pcb-rnd 2.4.0 (r34705/r32627)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

pcb-rnd part:

	[ar_cpcb]
		-Cleanup: use pen via padstack proto instead of old via diameters
		-Fix: don't use old via hole diameter, extract this from pen's via padstack proto

	[autoplace]
		-Cleanup: remove local vector implementation, use genvector for list of boxes

	[autoroute]
		-Fix: copy and validate route style via padstack proto instead of diameters
		-Change: switch over to using route style via padstack proto instead of diameters

	[build]
		-Fix: byaccic make rule: use full relative paths to all files instead of cd'ing into the plugin's dir - this way generated #line will have full path too which may be less confusing to some weaker C compiler implementation

	[cam]
		-Update: default file name derivation for new librnd export options vs. attributes API
		-Cleanup: const correcntess for the new librnd export options API

	[core]
		-Fix: implicit func declaration
		-Fix: c89 violations (empty declarators)
		-Fix: make Connection(find) result message more clear, especially when no object is found
		-Fix: moving selected objects to current layer uses the move object call that has the bugfix for moving floaters
		-Fix: padstack conversion shouldn't crash when it fails early, while counting layers
		-Fix: obj_line unreg: do not unreg endpoint objects, they were not registered in the first place
		-Del: old ring/hole diameter from the route style API
		-Del: remove internal, legacy board via hole/pad diameter setter functions
		-Del: box-box intersection code -> moved to librnd
		-Cleanup: pcb_board_set_via_drilling_hole() shouldn't check for code hardwired minimal/maximal hole size (it was overriden using force anyway)
		-Cleanup: pcb_board_set_via_size() shouldn't check for hardwired minimal/maximal via size (it was overridden by force anyway)
		-Cleanup: remove PCB_MIN_PINORVIAHOLE (hardwired minimum size)
		-Cleanup: remove PCB_MIN_PINORVIASIZE (hardwired size limitation, not in use)
		-Cleanup: remove PCB_MIN_GRID (hardwired size limit not in use)
		-Cleanup: remove PCB_MIN_PINORVIACOPPER (hardwired size not used in core)
		-Cleanup: remove pcb_custom_route_style - not used by anything, not reentrant; leftover from a pre-conf time
		-Cleanup: RouteStyle() action uses the central route-style-to-pen set function instead of trying to invent a local implementation
		-Cleanup: remove pcb_board_set_line_width() and pcb_board_set_text_scale() from the public API - trivial short functions used by only one caller
		-Cleanup: move undo serial management out from low level ApplyPen call so operation on selected will be a single undo serial
		-Cleanup: UI layers do have a non-NULL, valid data parent, a dedicated (pcb_data_t *) within pcb_board_t; this makes ui layers less of a special case and is one step toward being reentrant
		-Cleanup: registering a new UI layer requires a pcb_board_t * because UI layers are really under a board
		-Cleanup: change the internal API of ListBlock so whether selection should be done is an extra explicit argument - fixes the unwanted subc selection on show netnames
		-Cleanup: list_block_cb should never select; make object selection side effect an explicit argument in the basic list block call
		-Add: font ID field in the route style struct
		-Add: API CHANGE: undoable pcb_route_style_change() argument list extended with font id
		-Add: RouteStyle() can set the font property

		-Add: helper function to return pen via bbox larger side (useful for constructing via site search boxes)
		-Add: ApplyPen() action on object, for lines and arcs
		-Add: text object: undoable any-field change (low level)
		-Add: ApplyPen() for text objects
		-Add: ApplyPen for padstacks
		-Add: ApplyPen(selected) to complement ApplyPen(Object)
		-Add: public poly point preallocation API so loaders can save on reallocs
		-Split: padstack bbox calculation so that a prototype's bbox can be calculated too
		-Update: convert the default boards to lihata v8 - use explicit padstack vias and text scale in routing style

	[dialogs]
		-Fix: don't fancy executing an infinite loop when grid is set to zero in padstack library preview
		-Del: remove printer calibration dialog, print the url of the manual process instead
		-Update: librnd API change on export options ->value removal: use hid->argument_array instead
		-Add: padstack lib dialog: padstack prototype copy & paste using system clipboard
		-Add: action pstklib(board, retid) lets the user select a prototype from the board's list and returns the pid as long
		-Add: optional presel argument in pcb_dlg_pstklib() so it can select a padstack proto from the list on open
		-Add: pstklib() action: optional presel argument

	[djopt]

		-Fix: restore NULL info after drawing padstacks and misc virtual layers, before drawing UI layers to ensure proper UI layer display

	[drc_query]
		-Fix: default config: overlapping holes test: consider padstacks with hole > 0 only

	[export_lpr]
		-Fix: load default values for ps inherited fields as well while initializing the export
		-Del: remove calibration code that cross-called the ps exporter for the test page
		-Add: optional plugin configuration for printer calibration default value in X and Y directions

	[export_openems]
		-Fix: do not crash if excitation is not set (to_hz conversion returns error on input NULL)

	[export_png]
		-Fix: do allow exporting mask and bottom silk in CAM mode
		-Fix: in CAM mode render bottom side silk with invisible color if --as-shown is set

	[export_ps]
		-Cleanup: do not rely on PCB_MIN_PINORVIAHOLE for drill helper minimum setting, just specify a small-enough number - PCB_MIN_PINORVIAHOLE is going to be removed from the API
		-Fix: eps export: if CAM is active, do not omit the bottom silk when explicitly requested
		-Fix: eps export: when exporting the bottom silk with CAM, --as-shown applies far-side invisible-color

	[fp_fs]
		-Fix: configurable prefix filter bug required full match, not prefix match

	[gui_act]
		-Add: SetSame() works on text scale, thickness and font

	[import_mucs]
		-Change: switch over to using via pstk proto instead of diameters

	[import_sch2]
		-Fix: detect broken/unfinished import setup and invoke the dialog instead of reimport

	[io_bxl]
		-Update: use full relative path in byaccic generated files

	[io_lihata]
		-Fix: more graceful handling of invalid via hole dia problems (than assert)
		-Fix: write text scale and clearance dummies without creating empty nodes; also fixes typos in scale_x/scale_y dummies
		-Cleanup: remove route style old via diameters from internal API
		-Add: concept of route style unset font id, for compatibility with old boards
		-Add: v8 saves and loads route style fid (font ID) if it's not -1
		-Add: when saving <v8 route styles, convert via padstack proto to diameters
		-Add: v8 route style pstk protos: when loading an old file with diameters, create the prototype
		-Add: altough lihata v8 doesn't have via dia and hole dia in route style, accept it with a big warning (may be useful for manually written files)

	[io_pads]
		-Add: enable the plugin to load various versions of PADS ASCII boards

	[io_pcb]
		-Cleanup: move old route style parser code from core to io_pcb - nothing else uses it (nothing else ever should!)
		-Move: PCB_MIN_PINORVIACOPPER to geda/pcb loading - this value should be compatible with the hardwired value in geda/pcb
		-Split: route style compatibility save into a separate function (io_lihata will need to reuse it)

		-Add: code to create padstack prototype from route style diameters (on load)

	[io_tedax]
		-Fix: autorouter: don't use old via hole diameter, extract this from pen's via padstack proto

	[jostle]
		-Cleanup: use pen via padstack proto instead of old via diameters

	[lib_hid_pcbui]
		-Fix: don't try to verify or tune via geometry when using via padstack prototype

	[lib_compat_help]
		-Fix: compat pad save: properly reverse engineer rectangular polygons into centerline with stroke width, even for 45 degree rotated case
		-Add: route style compat API: helper for creating a via padstack proto from old via diameters (on load)
		-Split: compatibility via data extractor into a low level one that works from a prototype and the original high level one that calls this function for a padstack instance
		-Split: compat via pstk prototype generator from pstk generator into a separate function for reuse
		-Move: compatibility route style via pstk proto -> diameters converter from io_pcb to lib_compat_help as it will need to be reused in io_lihata for pre-v8

	[lib_hid_pcbui]
		-Fix: find best fitting route style instead of first fit - because of wildcard text settings
		-Fix: update pen by reselecting the current routing style after a routing style modification from the dialog

		-Add: route style dialog: font id button (invokes the font selector)
		-Add: route style dialog: concept of unset font id, for compatibility with old boards

	[menu]
		-Del: printer calibration menu item - no such feature anymore
		-Add: ApplyPen menu items for object and for selected
		-Add: menu binding for interactive custom grid setting

	[millpath]
		-Fix: the plugin depends on ddraft for intersection calculation

		-Cleanup: create local menu file for the puller plugin so its menus from the central menu file can be removed
		-Update: librnd API change on export options ->value removal: update export plugins on librnd calls
		-Update: export plugins: new way of loading default values for librnd API change
		-Del: remove clibration hook from all export plugins - API is going to be removed from librnd

	[puller]
		-Add: local menu file

	[qparse]
		-Fix: in non-function syntax stray whitespace at the end shouldn't induce an extra empty argument at the end of argv[]
		-Fix: update 'consumed' output to skip over closing parenthesis for function syntax or terminating semicolon

	[scconfig]
		-Del: special buildin-hack for lib_compat_help: core doesn't depend on it anymore

	[teardrops]
		-Fix: exto: set up intern copper layer offset when converting line into teardrop exto so that the new object won't change layer
		-Fix: exto: accept only copper layers for edit object

	[tests]
		-Update: vendordrill test res for the new pen terminology in info messages
		-Update: cam test refs for black bottom silk color (svg without --as-shown doesn't do the gray invis color anymore)

	[tool_std]
		-Fix: don't allow drag&drop cut&paste to even start if the rat layer is active - if we'd allow that, cut would remove objects but the subsequent paste would fail because the buffer tool can not be activated
		-Cleanup: use pen via padstack proto bbox size for searches instead of the old diameters
		-Add: place via from style proto
		-Add: render via xor-draw using real via geometry (from proto)
		-Add: xor-draw a clearance approximation when clearance indication is enabled
		-Add: cache via and text tool IDs

	[util]
		-Fix: sign verify typo: --print on crl should use the file name passed on command line
		-Update: repo.hu crl for another year

	[vendor]
		-Cleanup: remove PCB_MIN_PINORVIACOPPER, rather depend on conf node design/min_wid for fixing up invalid route styles
		-Cleanup: remove DRC section from the example - DRC in vendor files are not supported
		-Change: switch over from tuning the .Hole field of the routing style struct to deal with via padstack prototypes
		-Del: remove via pad diameter tuning - vendor drill is about changing drill sizes only, finding thin copper is up to the DRC

librnd part:

	[build]
		-Fix: make sure the local .so symlink is always updated so it never points to a previous, lower versioned .so build - matters for non-installed, from-source app compilation

	[core]
		-Fix: wrong action description for SetGrid()
		-Split: export option (default val) to attrib copy code to a separate function for reuse
		-Split: code that loads all export attributes/values from the options table for a hid into a public function so export plugin init code can call it
		-Import: cleaned-up box-box intersection code from pcb-rnd
		-Del: box list type: not generic enough plus no user left
		-Add: Grid(ask) for setting custom grids

	[dad]
		-Add: macro to set up an export option using an external hid_attr value

	[gtk]
		-Fix: do not lose the "mouse entered drawing area" event after closing a popup when the command line is open; fixes the "command line -> popup -> scroll -> scroll-lockup" bug
		-Fix: menu errors in message log should end in \n for a readable log
		-Fix: color conversion: 1 LSB got lost on a color conversion round trip half of the cases
		-Fix: win32 glue: wrong arguments to rnd_system() killed cache update on win32
		-Fix: accept 'ungrab' type of drawing area entering as enter event to fix a pan lockup on mid mouse button 'dragged' from outside to inside the drawing area
		-Fix: don't crash on setting mouse cursor when no tool is loaded

	[hid]
		-Cleanup: API CHANGE: remove ->value field from export options; export options should be const and current values should be maintained in hid->argument_array; this will fix a bug caused by unknown sizeof(enum) vs. void *
		-Cleanup: API CHANGE: read-only export option split: function callback option needs to get the value as well
		-Fix: const correctness in handling export/hid options: they are read-only
		-Fix: const correctness in taking hid options (read-only)
		-Fix: const correctness: store export options only in const
		-Fix: const correctness for the new API in hid_nogui
		-Fix: const correctness on export options in all core HIDs
		-Fix: const correctness in the older export option registration call
		-Fix: const correctness in DAD around read-only export options
		-Del: API CHANGE: remove the old, NULL hid option registration call - it won't work with the read-only option table
		-Del: remove the old ->value field of export options; since this struct is read-only in all export/hid plugins by now, it can not be written and the split _values[] array shall be used
		-Del: API CHANGE: RND_DAD_DUP_EXPOPT() - unsafe for read-only option tables
		-Del: the printer calibration hook, ->calibrate(): should be done outside of ringdove apps

	[hid_lesstif]
		-Update: export options ->value removal

	[lesstif]
		-Cleanup: argument handling; option table is read-only, follow the new API of split values
		-Cleanup: remove old, commented out pcb_width and pcb_height - the code uses hidlib struct for long enough not to need to remind us

	[loghid]
		-Cleanup: switch over to read-only command line option table to follow librnd API change
		-Cleanup: excess initialization of export opt ->value

	[util]
		-Add: sign verify: --print for human readable output
		-Update: sign: repo.hu crl for another year

		-Cleanup: unify render script function naming and calling conventions
		-Cleanup: simplify drawing the 'invisible'/'far side' doc/silk layers for the render script
		-Cleanup: disable code for excess GUI flushes after drawing the "invisible" (far side) objects in GUI mode

	[draw_fontsel]
		-Fix: use "element" color (default silk) for black and mark color for red: users who change their background color will likely to change these too to keep them visible

	[drc_query]

		-Fix: buffer to board copy: separate keep_ids from udpate extobj parameter; keep_ids is temporarily disabled but we still need to execute extobj updates
		-Fix: buffer to board copy: update all floaters to get it recalculated (for the current board state after placement)
		-Fix: dimension: don't crash on all-floater update
		-Fix: increase undo serial after conversion so each conversion can be undone separately

	[fp_wget]
		-Fix: fp_wget shall work from the converted lihata version instead of the converted fp version because the fp format is too limited

	[io_autotrax]
		-Add: io incompatibility error on saving text with clearance != 0
		-Add: io incompatibility warning for text rotated not in 90 degree steps

	[io_eagle]
		-Cleanup: wrong return type and unused vars

	[io_pcb]
		-Add: io compatibility error on saving text with clearance != 0
		-Add: read support for 4.3.0 pad center description in footprints
		-Add: comment on why the optional extra layer type should be ignored on read: geda/pcb code is totally broken and writes the _wrong_ layer type so it would even ruin outline layers while at the moment (4.3.0) it won't really let the user have editable mask or paste layer

	[io_tedax]
		-Add: io compatibility error on saving text with clearance != 0

	[lib_hid_pcbui]
		-Fix: do not create menu names for outing styles and layers with '/' in them, that interferes with menu path addressing and breaks the menu system on merge

	[librnd]
		-Change: link librnd using the .so files, with -l, instead of static linking (next step of librnd separation)
		-Fix: order of -l's does matter; link librnd first as in a semi-static setup libs like -lgtk need to come after librnd
		-Cleanup: remove workaround that was needed when librnd was static linked
		-Add: pcb-rnd-src helper script to set up LD_LIBRARY_PATH for source local execution
		-Update: use the new conf API option for simpler plugin intern config registration

		-Add: layer context popup: menu items for toggling wireframe and thindraw xforms

	[pcblib]
		-Fix: parametric footprint default param list for msop, qsop, ssop and tssop: don't use newlines, that's incompatible with original-awk (OSX)

		-Fix: typo in report name may cause rnd_printf to resolve argument not passed (%P)

	[scconfig]
		-Add: half-working -static for ./configure - some libs still need to be added manually

	[shape]
		-Fix: round rect poly: maximum rounding radius depends on number of square corners so rounding can go beyond half of a side
		-Add: the GUI shape generator prints an error message in the log about how exactly the round rect generation failed
		-Cleanup: const correctness on error report

	[show_netnames]
		-Add: netname label cache; invalidate the cache on netlist or board change
		-Add: invalidate the label cache on font change

		-Split: padstack shape size capture from the search code
		-Cleanup: make the code reentrant
		-Cleanup: don't use global PCB directly
		-Cleanup: use %mm trace prints for coords instead of unitless %f
		-Fix: don't convert doubles to int for drawing the arc - do proper rounding and convert to rnd_coord_t (so it works in 64 bit coords setup)
		-Add: teardrop extended object with a curved < mark on the exto 'E' mark

	[tests]
		-Add: automated tests for vendordrill skips
		-Add: vendordrill tests for all different rounding methods and pure loading
		-Fix: vendordrill tests: remove installation-specific full paths from the output

	[util]
		-Fix: pcb-rnd-svg: wrong return value on test-all
		-Fix: pcb-rnd-svg: be able to run pcb-rnd from source
		-Add: gsch2pcb-rnd needs to define rnd_app_package for anyload to compile
		-Add: sign: ./verify --print prints the crl or ca in human readable form

	[vendordrill]
		-Del: processing of the drc subtree (rather print an error with an URL to details on the anyload transition)
		-Del: do not load vendor name - it is not used for anything
		-Fix: use <> #include for librnd
		-Cleanup: use enum instead of macros for rounding rule names
		-Cleanup: use switch instead of long if()s for sorting out rounding rules
		-Cleanup: code terminology: use "nearest" instead of "closest" to match argument name

librnd part:

	[anyload]
		-Add: basic reg/unreg infra, action, loader,

		-Add: support for menu patches
		-Add: support for conf subtrees
		-Add: anyload() without arguments should pop up a file selection dialog

	[build]
		-Fix: enable the mkdtemp forward decl workaround for non-debug builds - on OSX feature macros disable the mkdtemp prototype
		-Fix: missing ptrdiff and other type detections required for libporty_net on some systems
		-Fix: detect ioctl and fionbio for libporty_net
		-Fix: cross compilation: build puplug objects in separate files for host and target instead of running make clean and risking a race condition
		-Fix: don't append NULL to CFLAGS when there's no -pedantic available
		-Workaround: apple uses multiple -framework words in the LDFLAGS - we need to patch the list before running uniq so they are all kept
		-Add: Makefile rules for symlinking local .so and .so.2 libs in the source dir, for pcb-rnd's temporary from-source execution
		-Add: option for static linking librnd (windows needs this because of broken dynamic link: dlls can't reference host app symbols without some extra magic)

	[conf]

	[core]
		-Fix: local realpath implementation shall return NULL when path not found (security...)

		-Add: grid(get) - returns current grid size (for scripting)
		-Add: CreateMenu: an optional argument for setting the accel (key binding) on the new menu

	[gtk]
		-Cleanup: disable more theme setting code that fell out of usage
		-Fix: do not lose the "mouse entered drawing area" event after closing a popup when the command line is open; fixes the "command line -> popup -> scroll -> scroll-lockup" bug

	[hid]
		-Cleanup: const correctness: passing on a pixmap for HID draw can not be const, because the HID will want to load ->user_data for caching

	[hid_gtk2_gdk]
		-Fix: negative gc width always means size in pixels
		-Fix: don't crash on invalidate request before the GUI is fully initialized, just ignore it
		-Fix: gdk render optimization bug on zero-length lines

	[lib_gtk_common]
		-Fix: do not query xy on pan stop (middle button release): results in gray GUI lockup
		-Fix: inactivate pan mode when opening context popup (works around a gtk misfeature: the popup takes focus and mouse button release is not delivered)

	[menu]
		-Fix: menu patch: removing a whole menu tree should first remove submenus, by the actual submenu nodes not by other lihata nodes

	[poly]
		-Fix: pline embrace circle: accurate hline-line intersection calculation so the code doesn't get confused on near misses

	[script]
		-Workaround: manually register the languages provided by the fawk binding so they are found even if there is no system installed fungw
		-Fix: printing uninitialized string in error message when script fails to load
		-Fix: guess lang for the builtin case needs .pup ending because the rest of the code will want to remove it
		-Fix: remember hidlib context for timers so it is possible to execute actions from timers
		-Fix: live script stop should call script preunload() to give the script a chance to clean up
		-Fix: when live script dialog is closed, call script's preunload when unloading
		-Add: live scripting hotkey: {p s l} (for plugin, scripts, live)
		-Add: math helper actions: pcb_rand() and pcb_srand()

	[win32]
		-Fix: use rnd_system() instead of system() for the gtk startup hack on windows

		-Fix: don't attempt to compile puplug for the host, let librnd do that
		-Fix: dynamic link plugin template: path to librnd's local templates changed
		-Fix: static link order: librnd-hid needs to come after librnd-poly because poly depends on core

		-Fix: uniq_name links to librnd static libs instead of cherry picking objs (which won't be available when librnd is installed)
		-Fix: uniq_name: don't use invalid pointer and don't print with %p (format not guaranteed); use array offset and #%d instead for maximum portability

		-Fix: cam: do not depend on installed pcb-rnd
		-Fix: suppress missing standard lib warning and empty lines in cam test
		-Fix: cam: layer group export test: can't export @inivisible any more, it's an on-screen-only virtual layer

		-Fix: make -ldl optional, some systems (e.g. windows) don't have it
		-Fix: set the default value of disable_so to false so the variable always exists
		-Fix: hidlib plugins with internal menu file need a different path reference for building the file
		-Fix: gen_conf.sh shouldn't try to keep all html files open for the whole time of generating them - some systems will have a lower limit on open fds
		-Fix: wrong order of args in svn:externals

		-Change: better handling of missing dynamic linking; explicit disbale also disable puplug -ldl detection
		-Change: compile ureglex plugins with shared common exec
		-Add: compile and install sphash - the build infra provided by librnd depends on it
		-Add: --disable-so ./configure option - especially for windows, where .dll is not comparable to .so, and the cross-compilatio uses static linking with librnd anyway
		-Add: hidlib install plugins
		-Add: require fungw pup installation path to present (required for proper script plugin loading in case of system installed fungw)
		-Add: print TODO messages only in debug compilation
		-Tune: skip a level of unnecessary indirection when compiling host puplug

	[core]
		-Fix: hid uninit sequence: keep hid structs until after pup unload so plugin uninit cals won't address into already free'd memory
		-Fix: do not attempt to load plugins from installation libdir if installation path is not available compile time (e.g. on windows)
		-Fix: do not register empty path in puplug plugin search path

		-Fix: do not include non-standard <memory.h>
		-Fix: rnd_setenv() implementation in case of only putenv is available caches all the sets and makes sure each variable is stored in memory only once
		-Del: do not auto-load all fungw scripting engine plugins - the script plugin will pick the ones needed
		-Cleanup: remove useless comment
		-Add: HID API: option to initialize export option values and load those with the command line args, instead of overwriting the default value
		-Add: HID API: extended export plugin options registration that remembers the hid so that the command line arg parser uses the right backup memory per HID
		-Add: init stage 3: automatically load all plugins from all plugin directories available (optional)
		-Add: add fungw pupdir to the pup search path so scripting plugins can be loaded

	[DAD]

		-Fix: zoom-win call updates gtk scales so the view doesn't jump away e.g. in the first zoom after a zoom extent

	[lib_hid_common]
		-Add: action API for toolbar init so lib_hid_common doesn't need to be static linked
		-Add: rnd_zoom() action to expose the internal zoom mechanism - so that ringdove apps don't need to link lib_hid_common directly
		-Add: publish window placement save utility functions that are used by pcb-rnd preferences window

	[libporty_net]
		-Fix: try a differen AIX <string.h> workaround to avoid warnings on Linux
		-Cleanup: comment out #warnings, they are not portable
		-Workaround: AIX select problem

	[libuirc]
		-Fix: pick up actual nickname from the server from the 001 message (this may be different from the nick we wanted to set, due to nick name length constraints)

	[poly]
		-Change: increase rtree stack max size for real complex polygons

	[script]
		-Change: move the plugin to librnd so other ringdove apps have the same scripting (moved at pcb-rnd r33401)
		-Fix: remove local engine name guessing, search fungw engines to figure
		-Fix: language listing: strip whitespace from language name
		-Fix: script load logic depends on the ext/lang/eng cache instead of all plugins already loaded
		-Fix: load fungw language binding plugin from the dir fungw got installed to
		-Fix: live scripting language listing works from only fungw pup install dir
		-Fix: live scripting: get language list from the $script-ext field of the pup files, not from the $desc (as the desription is not intended to be parsed)
		-Fix: pass proper hidlib context to live_run() so that script reload from the GUI doesn't crash
		-Fix: use librnd's globalconst instead of pcb-rnd's so the plugin can be moved to librnd later
		-Del: pcb_script_pup_paths - librnd places fungw pup install dir on search path
		-Del: remove local pup map/parse function from live_script, use puplug's
		-Cleanup: c "scripting" API decoupled from pcb symbolism (while keeping backward compatibility for now)
		-Cleanup: namespace: switch from pcb_ to rnd_ where possible, to prepare the transition from pcb-rnd to librnd
		-Cleanup: const correctness
		-Cleanup: publish guess_lang(), it's used from multiple parts of the code
		-Cleanup: use the right vector type for the engine cache
		-Cleanup: remove unused var
		-Update: fungw API change on pup_list_parse_pups() callbacks
		-Split: undo calls (used in live script) to a separate glue .c so it will be easier to replace them with action calls plus it will show what actions the host app needs to deliver
		-Change: use pup's readdir calls in the language map code as it would be moved to puplug
		-Add: when language is unspecified for a script, use fungw engine based guessing
		-Add: determine default script file name extension by calling the fungw engine for the currently selected language
		-Add: debug action for printing the language list
		-Add: guess_lang: parse pup files for the $script-ext lines and prepare for building hashes of those
		-Add: guess_lang uses the extension/language/engine cache built from the pup files
		-Add: pass on hidlib to script to more calls, especially script loading calls, in preparation of setting "script user call context" during script initialization
		-Add: set up "script user call context" during script load/initialization so the action calls made by the script have the right context
		-Add: use the action API for arranging undo with the host app instead of hardwiring pcb-rnd undo calls
		-Add: more details on script parse failure (which fungw plugin reported the problem)
		-Add: corner case: if a lang name is really a fungw engine name (without the fungw_ prefix), accept that too (for cli)
		-Add: live scripting: list language aliases too, so bash is found for cli

	[tests]
		-Fix: librnd make clean removes all empty dirs and temp fiels generated
		-Cleanup: rename pcb-printf/ to rnd_printf/ because that's the name of the call and the API we are testing
		-Update: pcb-printf test should link the whole lib instead of cherry picking objects

	[ureglex]
		-Import: exec part of r267
		-Add: README with the original url and mention of public domain

pcb-rnd part:

	[act_draw]
		-Cleanup: remove global PCB dependency

	[act_read]
		-Cleanup: remove global PCB dependency
		-Add: idplist(print)

	[asm]
		-Add: menu for the feature plugin

	[ch_editpoint]
		-Add: plugin to indicate object editpoints and terminal names on hover

	[ch_onpoint]
		-Cleanup: don't calculate arc endpoints locally, call the dedicated function
		-Cleanup: move onpoint object lists from core/crosshair to ch_onpoint
		-Move: onpoint related code from core to plugin ch_onpoint to make core smaller and cleaner
		-Fix: don't crash if there's no tool
		-Add: allow indication only for tools that can edit geometry

	[core]
		-Cleanup: use vtp0 and pcb_any_obj_t for on-point highlight instead of a locally defined type+obj* struct to reduce code size (pcb_any_obj_t has a type field)
		-Cleanup: on-point: DrawLineOrArc(): don't need to pass type+obj, pcb_any_obj_t does include the type
		-Cleanup: on-point: DrawLineOrArc(): no need to do trickery with the layer argument, lines and arcs do remember their parent layers in pcb_any_obj_t
		-Cleanup: on-point: make DrawLineOrArc() static - needed by onpoint only; rename to remove CamelCase
		-Cleanup: decouple pcb_board_set_changed_flag() from PCB, adding a pcb_board_t * context pointer first arg
		-Cleanup: remove global PCB dependency from padstack actions
		-Cleanup: remove global PCB dependency from conf actions
		-Cleanup: remove global PCB dependency from font actions
		-Cleanup: remove global PCB dependency from file actions
		-Cleanup: pcb_xordraw_movecopy() grew too large, split it up to a per object type function
		-Cleanup: onpoint indication should be an obj common bit, not a flag - it's temporary data never to be saved
		-Fix: get low level text scale X,Y change undoable
		-Fix: make ChangePinName() undoable
		-Fix: make ChangeNonetlist() undoable
		-Fix: padstack undoable change hole shall call the proto updater to keep caches and hashes in sync
		-Fix: arc wireframe draw: never call the hid with negative radius (that resulted in artifacts)
		-Fix: RouteStyle() action help text did not reflect how the code worked
		-Fix: route style: text scale is really an int, not a coord
		-Fix: hole diameter change in padstack op shouldn't use old drc setting to limit minimum size; the padstack editor and the property editor already allows the user to set any size, don't do arbitrary limiting here either
		-Fix: pcb_text_draw_string_simple() shall set up xform and info to avoid crash
		-Fix: don't crash on pcb==NULL in text mirroring in buffer
		-Fix: don't use PCB from some actions, that's not available while new board is created
		-Fix: move crosshair out to the limit before removing the old board - this should trigger all ch_ plugins to release their old data, to avoid stale pointers
		-Fix: drc print: don't print measured or expected value if it is FGW_INVALID
		-Fix: when removing/destroying a polygon, remove it from parent subc term list
		-Fix: footprint parameter split: find and remove the trailing ')' even if there are spaces after it
		-Fix: set rendering to positive before drawing the fab layer (might be the first thing drawn on an empty board)
		-Fix: ChangeFlag doesn't have thermal anymore (thermal is not a flag bit)
		-Fix: SetThermal() with value non-zero should also turn on thermal
		-Fix: update library entry parent after sort or array relocation so it doesn't point to invalid/free'd memory
		-Fix: clear_buffer should reset buffer origin as well so it is not inherited between operations
		-Fix: new board creation crosshair state mismatch caused sw render HIDs to lose xor draw after creating a new board
		-Fix: low level label draw: separate x and y text mirroring is possible now, use it (fixes ctrl+tab text mirror bug)
		-Fix: turn off clearance optimization for line/arc/poly vs. poly intersection check if bloat != 0 (it caused shorts missed)
		-Fix: make subc flag change undoable (affects the lock tool)
		-Fix: SetThermal(): wrong description on the meaning of the numeric style values
		-Fix: SetThermal(): allow value 6 as well
		-Fix: pcb_net_find_by_obj() shouldn't crash on a terminal whose subc has no refdes attribute
		-Update: default boards are of lihata board v7, so plain save will not downgrade new boards to v6
		-Change: use style clearance for 'show drc clearance' instead of bloat
		-Change: conf field descriptions of the old DRC fields, which are now either obsolete or repurposed to limiting sizes
		-Add: tool infra: flag to mark tools that can edit object geometry
		-Add: generic, undoable attribute set function
		-Add: generalized subc layer allocation based on copying an existing subc layer
		-Add: respect rnd_render's ->override_render so loghid works
		-Add: padstack proto update makes a cache in tr[0] about which shapes are connected to the hole or slot
		-Add: padstack proto update calculates a cached prototype bit that indicates if all copper shapes are connected by the hole/slot
		-Add: RouteStyle(): undoable on set
		-Add: RouteStyle(): undoable route style name change (and query)
		-Add: RouteStyle(): commands for setting and querying text scale and text thickness
		-Add: RouteStyle(): undoable new and del commands
		-Add: extend the footprint API with an option for copying tags
		-Add: plug_io for saving and loading padstacks
		-Add: crosshair code: build a cache for attached object drawing: publish a clean() function that needs to be called before any crosshair attached object change so a cache can be maintained
		-Add: if a polygon has the clearpolypoly flag and showing the clearance is enabled, calculate the clearance offset poly and draw it while the poly is being moved or copied
		-Add: polygon helper: calculate the clearance polygon of a text object, without subtracting it
		-Add: when a text object is being moved, indicate the true clearance when clearance indication is on
		-Add: draw the clearance (union on all copper layers) around the padstack when it's being moved
		-Add: throw an error if no drc rule got executed
		-Add: crosshair: generate an event for updating screen indications when crosshair changed position
		-Add: editpoint indication on line, arc, polygon, padstack objects
		-Add: layer pointer to ID conversion (helper function)
		-Add: in-place subc replacement: keep thermal flags on terminals (map and apply thermals)
		-Add: subc in-place replacement: make a map of floaters, attempt to match them up and move/rotate new floaters accordingly
		-Add: find.c: publish low level pcb_isc_pstk_line_shp(), lib_polyhelp needs it for hole-on-contour
		-Add: find.c: padstack shape to polyarea converter (helper function)
		-Add: SetThermal(): support the 'noshape' style

	[dialogs]
		-Del: preferences: half of the old DRC sizes - use the new DRC definitions
		-Cleanup: rename DRC sizes to limit sizes in the code to reflect change in the code logic
		-Fix: flag changes from the flag edit dialog are undoable
		-Fix: when the padstack editor changes the hole or local clearance in a prototype, make sure the prototype is updated (for the hash and caches)
		-Fix: padstack proto save file name memory leak
		-Fix: library dialog, refresh button: print an error message if parent/root can not be found
		-Fix: don't crash when library window preview is called with NULL footprint name (may be a result of a broken parametric footprint), just clean the buffer so that nothing is shown in the preview
		-Fix: dlg_confval_edit(): uninitialized default value for optional argument 'modal' (may cause crash on drc definition edit)
		-Change: merge limiting sizes and misc sizes, by now they are the same as limiting sizes are no longer DRC-related
		-Add: padstack lib dialog: load and save buttons for padstack prototypes
		-Add: default file name for padtsack save is padstack.lht
		-Add: preferences, sizes&drc: print an error message if there is 0 drc plugins available
		-Add: convert the manage plugins dialog into a non-modal dialog box that presents an alphabetically sorted list of plugins in a list
		-Add: manage plugins: button for unloading plugins
		-Add: plugins dialog: print reference count of each plugin (useful for debugging)
		-Add: make layer comb flag change undoable

	[doc]
		-Fix: packager's doc: grammar about diagnosing (in package desc); missing punctuation in package desc
		-Fix: use both pcb-rnd's own plugins and librnd's svn extern'd plugins when mapping for packager's doc
		-Fix: plated slots can be represented already
		-Update: renumberblock description for subcircuits
		-Update: conf tree for the drc "show/enforce" change
		-Add: mention imagemagick as soft dependency for running some tests
		-Add: clarify what ChangeSize() does to subcircuits
		-Add: action doc for RouteStyle(); document 'del' and 'new'
		-Add: document the low level ttf import action
		-Add: lihata format doc: document the new file format for padstack protos: pcb-rnd-subcircuit-v*
		-Add: developer doc: plugin development howto for local, per plugin menu files
		-Add: query: document coord(), netlen(), isvoid(), layer_setup(), int(), double() and .net
		-Add: query: document user functions
		-Add: refine the nonetlist flag sentence explaining the actual effects
		-Add: explain how openscad-transformation attribute is not used for subcircuit rotation
		-Add: INSTALL references the packaging doc - maybe this will help new packagers figure where to look
		-Add: link regex syntax from the appendix and from the feature doc

	[drc_query]
		-Fix: invalid drc value is FGW_INVALID, not FGW_VOID
		-Fix: action that sets drc def should create the conf node and set the default value even tho the def is created in multiple steps when done in actions
		-Fix: make sure definition default value is set only once, not overwriting exisitng value
		-Add: refine stock drc rule violation report with expected/measured values

	[export_openscad]
		-Fix: respect options set from the GUI

	[export_stl]
		-Fix: do not apply holes/slots that fall on the board contour, that'd result in invalid model
		-Fix: use clipped contour poly instead of the as-drawn one, so all sort of tweaks (like half-hole cutouts) appear in the output

	[export_test]
		-Del: plugin removed in favor of the more generic loghid plugin (in librnd): the actual sequence of calls HID heavily depends on the do_export() implementation of the GUI/export hid chosen, so even if export_test worked, it would not have shown the same sequence as any actual export/screen-render

	[extobj]
		-Cleanup: remove code duplication on subc layer object copy
		-Cleanup: use the central subc layer allocation helper function instead of a local implementation
		-Fix: handle buffer copy/cut/move corner case: make sure the subcircuit is not added to the rtree twice
		-Fix: when (all) floaters are selected, also select the parent subc so it can be copied/moved to the buffer

	[find]
		-Cleanup: remove direct fctx->mark mark test and sets where it matters: wrap them in inline functions so they can be extended for the multi-component objects
		-Fix: don't assume hole/slot connection within a padstack if the hole/slot is not plated; special case: if term ID is set on a padstack with disjoint copper shapes, it should be taken as connected; rationale: each shape has the same terminal ID and we generally assume same-terminal-IDs are connected within the part soldered on
		-Add: make the padstack shape vs. padstack shape intersection (geo code) API public, padstack prototype code caching the shape overlaps with holes will need it
		-Add: maintain a multimark hash table in find context and allocate it for padstacks when needed (when not all copper shapes are connected)

	[font]
		-Fix: when unlinking a font (e.g. for fontedit()), re-link the parent of all symbol arcs and polys to avoid invalid ref

	[fp_fs]
		-Add: configurable prefix based file name ignores on lib mapping
		-Add: suffix based file name ignore from config (during lib mapping)

	[import_tinycad]
		-Add: atomic netlist import: undo undoes all at once

	[import_ttf]
		-Add: Erich's patch on cubic

	[io_lihata]
		-Cleanup: read: group all global states in a struct (reduce global vars)
		-Cleanup: read: do not depend on a global variable for the context, pass the read context struct down in every call that needs it
		-Fix: do not accept negative arc radius on load, change it to 0 and throw an error
		-Fix: buffer load shall set read version from the header, else padstacks won't work (as they did not exist in v1)
		-Update: make v7 the default format to use by extedit
		-Add: save padstack file: write a new header and the padstack proto subtree with ID 0
		-Add: parse pcb-rnd-padstack-v* for the padstack proto in it

	[io_pcb]
		-Add: long, detailed error message about non-undoable layer swaps

		-Add: atomic netlist import: undo undoes all at once

	[lib_compat_help]

	[lib_hid_pcbui]
		-Fix: route style: text scale is really an int, not a coord

		-Add: make del and new buttons on the route style docked dialog undoable
		-Add: icon buttons for all layer visible/invisible

	[lib_polyhelp]
		-Cleanup: use pcb_board_set_changed_flag() instead of directly setting the changed flag

		-Del: local scconfig templates for the build - use librnd's
		-Del: rnd_r_end() - dummy call to empty function, the iterator doesn't allocate anything
		-Move: box direction enum and macros to from librnd to local box_dir.h (needed by autoplace and autorouter only)

	[menu]
		-Fix: buffer content load, {b f l}, should clear the buffer before the load so only the new content is in the buffer by the end of the operation

	[tests]
		-Fix: RTT: handle missing convert(1) or compare(1) by really skipping the corresponding tests
		-Del: librnd test - it's in the now separate librnd project

		-Fix: shift-click in-place footprint replacement from buffer shall keep rotation and side of the original footprint
		-Fix: thermal tool should work when clicking on subc padstack
		-Fix: changing the lock state of an object shall mark the board changed
		-Fix: tool_move calls extobj float_pre and float_geo in pair so the extended object is not messed up
		-Fix: escape in arc and rectangle tools shouldn't immediately switch to the arrow tool but first fall back to the arc or rectangle initial state
		-Fix: lock: increase undo serial after locking/unlocking so they don't batch with random other operations
		-Change: use style clearance for 'show drc clearance' instead of bloat
		-Add: thermal tool: better fallback mechanism on multiple objects found and indicate if didn't do anything because all candidates were locked



librnd part:

	[librnd/build]
		-Del: tests left over from pcb-rnd
		-Del: remove pcb-rnd leftovers from Makefiles
		-Move: scconfig lib from scconfig/ to src/ so it is part of the single install subtree for reuse by apps
		-Move: gen_conf.sh to librnd/scconfig (with installation) so apps can reuse it
		-Move: scconfig templates from scconfig to src/librnd/scconfig as it's becoming installable for apps to reuse
		-Cleanup: detach building the plugins from $(PLUDGID) so the temporary in-pcb-rnd build still works
		-Cleanup: move src_plugins to src/librnd/plugins for easier svn externs and consistency with the installation later
		-Cleanup: plugin headers should be #included as <librnd/plugins/*.h> for portabilirty
		-Fix: make sure make dep generates the dependencies with full relative path (requires an extra step of 'sed' to work around gcc's shortcomings)
		-Fix: broken installation of buildin.hidlib.h
		-Fix: missing dependency on test-rnd executable to buildin.hidlib.h
		-Fix: use the same path notation for buildin.hidlib.h dep as for the build rule
		-Fix: mark all plugins part of $hidlib
		-Change: install doc and data in /librnd, not in /pcb-rnd
		-Add: #define LIBRND_ROOT so configure compiles
		-Add: install minimal libfungw headers and genht headers (apps will need these)
		-Add: make map_plugins.sh more generic so ringdove apps can reuse it without having to copy it
		-Add: install map_plugins.sh so apps don't need to copy it
		-Add: temporary branch in the internal conf generator template for pcb-rnd, as long as it needs to compile librnd locally
		-Add: set librnd plugin root from the Makefile so plugins are found

	[librnd/core]
		-Cleanup: dedoxygen comments

		-Del: pcb-rnd related docs
		-Del: rnd_r_end() - useless dummy
		-Del: remove vcs comment mentioning multiple crosshair shapes from the copyright banner - that piece of code got removed
		-Fix: RND_ACT_CALL_C() needs to get hidlib as first argument and set up the call properly because action code depend on the hidlib context pointer
		-Fix: can't pass function pointer in low level C action call because there's no place the temporary func wrapper could be allocated
		-Fix: indicate error on action not found in parse action also in the case of action with arguments
		-Fix: str2coord for action arg conversion: do not crash on empty coord
		-Fix: don't crash if menu file did not parse
		-Fix: hid uninit sequence: keep hid structs until after pup unload so plugin uninit cals won't address into already free'd memory
		-Fix: don't crash if rnd_tool_get() is called before tool init
		-Fix: DAD: coord spin: accept 0.00 as legal value even without unit (special case)

		-Fix: mark plugin a hidlib plugin
		-Fix: preserve override_render bit after setting up the delegation
		-Add: set HID bit 'override render' to capture rendering calls
