+pcb-rnd 2.2.2 (r32050)
+~~~~~~~~~~~~~~~~~~~~~~
+	[act_draw]
+		-Add: PolyBool() action
+		-Add: low level draw using gc: DrawText() and DrawColor()
+		-Add: DrawLine() for low level, gc based rendering
+		-Add: DrawPoly() for low level, gc based rendering
+
+	[act_read]
+		-Fix: missing argument in ReadGroup() syntax description
+		-Add: ReadGroup() field accessor: ltypehas matches the 4th argument's layer type flag (specified as a string) and returns 0 or 1 if the layer group has that type
+		-Add: ObjCenter() action that returns the x or y coord of the center of an object (for scripting)
+
+	[autoroute]
+		-Fix: optimize with manhattan lines only
+		-Fix: refine the 'netlist stale' error message to get the user use the right rats optimization
+		-Del: false-positive(?) assert
+		-Add: temporary rats nest optimization for the old autorouter (manhattan)
+	[build]
+		-Add: detect byaccic and ureglex unless disabled
+		-Add: generate byaccic and ureglex rules
+	[cam]
+		-Fix: GUI: do not create excess directories while the user is typing an output path
+
+	[clearance]
+		-Add: polygon's enforce_clearance field
+
+	[conf]
+		-Add: public counter on how many times each conf root got replaced; this helps the caller detect side effects of e.g. loading a design file thay brought its own design level conf
+
+	[core]
+		-Fix: when freeing a subc, don't unreg it if parent is INVALID: it may simply be an unregistered subcircuit
+		-Fix: idpath: str->idpath conversion went wrong when path was prefixed with data address
+		-Fix: idpath: idpath->str in non-relative mode shall insert data name in front of the path
+		-Fix: when loading a new board, if it doesn't have a conf subtree make sure to reset the design role conf tree upon succesful load so the design conf of the previous board won't leak in
+		-Fix: unnecessary recursion in dynflag clear (turned O(n) into O(n^2))
+		-Fix: padstack broken ring check: a ring can not be broken if there's no hole
+		-Fix: io incompat listing in batch mode
+		-Fix: selected operation shall recurse and apply to subc floaters
+		-Fix: MoveLayer() gi and ga shouldn't allow creating new layers in a substrate group (happened on the cross-section view)
+		-Fix: object snap: use mouse coord, not crosshair coord so multiple snap points in between grid points are accessible; screen-search for snapping start with grid/8, then check grid/4 radius before searching in the original grid/2 - this gives it a chance to find the closer object first
+		-Fix: PCB_FP_FOPEN_IN_DST_ shouldn't use FILE as sizeof(FILE) is not always known
+		-Fix: cursor key direction mixed up in menu file
+		-Fix: toss buffer should not copy/move objects that are part of a subc (fixes bug: floater refdes text copied as a standalone second text object)
+		-Fix: RouteStyle() set generates the necessary route-style-changed event and if we were setting the current style, updates the pen too, so the current style stays selected
+		-Fix: do not double-add subc-parts in the rtree on move-buffer undo
+		-Fix: snap: grid realign should use crosshair coords, not mosue cursor coords, but grid size is still set to 0;0 - this allows both picking the alignment to a "background image" and realign to an object
+		-Fix: snap: prefer snapping to subc origin over snapping to grid
+		-Fix: arc split undo: add the new arc to the remove list
+		-Del: layer naming styles other then pcb-rnd and fixed (old, pre-CAM gerber layer namings)
+		-Del: special case code that placed donut rats
+		-Cleanup: prefix LIB_ enum members with PCB_ to keep the namespace clean
+		-Move: deprecate the MinClearGap() action; move it from core to oldactions plugin
+		-Add: footprint API: new hook for moving file type detection from fp_fs to format plugins
+		-Add: extend the fp_fopen() API so it can split up the file name to sub-footprint name and this info is accessible for the caller
+		-Add: subfpname parameter to the footprint parse API so multi-footprint files get which footprint to load
+		-Add: implement pstk prototype free fields (also fixes related memleaks)
+		-Add: fungw: automatic idpath type conversions
+		-Add: inline function to calculate object iid
+		-Add: Netlist() action commands for enabling/disabling all rats
+		-Add: text clearance style is determined by 'boolean' text attribute "tight_clearance"
+		-Add: text scale_x and scale_y
+		-Add: generic call for retrieving a pointer to the thermal char of any object (to unify padstack and non-padstack access)
+		-Add: undoable any-object thermal operation (works on lines and polygons)
+		-Add: text placement by bbox: create text utility function by bbox/anchor scaling/placement (useful for alien formats)
+		-Add: when a footprint format supports multiple footprints per file, map the file and offer selection on import
+		-Add: optional interactive object list selector for the case there are multiple objects found on a screen search (the user can pick one)
+		-Add: local (per layer-type) clearance change in prototypes are undoable
+		-Add: make padstack proto shape grow undoable
+		-Add: pstk proto scale is undoable
+		-Add: Netlist(): AutoLen and NoAutoLen actions to change automatic net calculation bit of a net
+		-Add: generalize the board thickness calculation function so it can calculate the thickness of a stack between two layer groups, optionally filtering for layer group type as well; also works for a subset of the stack
+		-Add: expose the API for deciding if two lines overlap and can be simplified
+		-Add: layer group addressing syntax: #gid, for use from scripts
+		-Add: RouteStyle(): upgrade to be able to set and get some fields
+		-Add: RouteStyle() accepts "@current" as first argument for working with the current style (useful for set and get)
