librnd 3.1.1 (r34045)
~~~~~~~~~~~~~~~~~~~~~
	[core]
		-Fix: conf system shouldn't throw error on shifting 0-length array for prepend
		-Fix: suppress error message on duplicate action and choose the app's action to keep for the actions that got moved from pcb-rnd to librnd at librnd 3.1.0; this is how librnd 3.1.1+ will work with old pcb-rnd executables
		-Fix: comment description of the dialog box geo change event: it means geometry _may_ have changed (gtk4 for exmaple will flood with unchanged geo on leave/enter)
		-Fix: set as many of the -c plugins/ before gui/export initialization as possible, but then try again the ones that didn't work after export/gui initialization: they may be export/gui conf nodes; for exmaple this allows setting opengl backend via -c even tho it is a hid_gtk_* plugin conf node
		-Fix: input handler makes event with hidlib (when hidlib is known)
		-Fix: provide a new set of key input handler calls to pass on hidlib to the event handler
		-Fix: DAD: wrong parameter name in comment about "tree row append under"

	[doc]
		-Add: developer doc: drawing on DAD widget and rendering path through HIDs and libs
		-Fix: packager's: remove $C from packages.html when not used
		-Fix: packager's doc: remove duplicate $PREFIC/lib/librnd3/scconfig from file listing

	[gtk]
		-Fix: remove gtkx cflags and ldflags: gtk2 plugins should use gtk2 flags, gtk4 plugins should use gtk4 flags so it is possible to compile both as plugins
		-Fix: hidgl_init() needs to be called on an existing gl context so it needs to wait until the widget is created
		-Fix: force-realize the new dialog after creation and iterate so that it is really created before returning so that the caller can manipulate widget states
		-Fix: dlg_attr* widget implementations should be dispatched to per-version gtk common instead of directly including global common - this gives the version dependent layer a chance to override or extend dad widget implementations without a maze of #ifdefs
		-Fix: hid glue: call backend uninit on pixmap uninit to get bakcend caches free'd
		-Fix: don't use gdk pixmap type directly in common code, gtk4 won't have it
		-Fix: don't call implementation-specific pixmap uninit if it is not available
		-Cleanup: use hidgl reset at the end of crosshair draw instead of low level gl xor mode setting
		-Cleanup: do not include stencil and opengl headers directly, everyhting shall go through hidgl.h
		-Cleanup: gtk2-gl shall not incldue opengl.h as no low level drawing is done
		-Cleanup: top window placement function name reflects its timing nature
		-Cleanup: gdkc_window_get_pointer() should have no return value (not used at caller)
		-Cleanup: compat API: unify calling convention on paned: pass GtkWidget and cast in compat
		-Cleanup: const correctness on gdk key query
		-Cleanup: move gtk2-only tree table keyboard workaround to the gtk2 layer so common code doesn't need #ifdefs on gtk version
		-Add: abstract drawing area type and class for the preview widget: in gtk2 it's a drawing area in gtk4 it's a GLarea
		-Add: preview opengl rendering creates new context with low level draw before first draw
		-Add: support for sparse grid in gtk2 and gtk4 opengl render
		-Add: bind gl texture free

	[gtk2]
		-Del: remove top window resize grip widget: it's not a natural gtk thing, it never made into lesstif or the gtk4 port and poll shows nobody would miss it anyway
		-Fix: missing include for preview context init
		-Fix: wrong order of hidgl init and new context calls in top window drawing area
		-Fix: correct "top-left" coords of pixmap rendering when flipped
		-Fix: flip (mirror) content of pixmap if displayed on flipped board
		-Fix: when rendering pixmap in composite rendering mode, also calculate and set clip
		-Fix: don't let global grid extend beyond the drawing area even if board is flipped
		-Add: uninit pixmap call that frees local transformed caches

	[gtk4]
		-Fix: do not scale color for transparency, it makes the output too light
		-Fix: window placement: window x;y needs to be queried separately because allocation is in window-coordinates
		-Fix: drawing area realized signal doesn't have a return value
		-Fix: make sure lib_gtk_common conf file is specified only once to avoid redundant Makefile rules generating the C version of the file
		-Fix: always declare gtkc_event_*
		-Fix: when acquiring x;y from a widget for a non-mouse event, convert surface coords into widget coords (fixes pcb-rnd "del key jumps crosshair away" bug)
		-Cleanup: remove xor color tuning from high level: in the vao backend we do not have real xor, only some blending cheat so color needs to be tuned locally
		-Cleanup: compiler warnings: missing cast on paned
		-Cleanup: remove scrollbar dead code
		-Cleanup: const correctness in css bg color set
		-Cleanup: realize/unrealize singals do have void * user data even if the code doesn't use it at the moment
		-Cleanup: rnd_gtk_tree_table_arrow_width() is gtk2-only
		-Cleanup: missing casts for top window custom scrollbar
		-Cleanup: wrong number of arguments for wt_preview singal callback
		-Workaround: gtk4 bug: GUI locks up if popup menu is not hidden before executing actions, e.g. in case of context menu inserting new layer
		-Add: call gl render
		-Add: port wt_preview compat to gtk_gl_area
		-Add: comment about popdown memleak and gui lockup
		-Add: top window and attribute dialog delayed placement because gtk4 is fighting it
		-Add: top win scrollbar widget: "jump here" when clicked outside of the slider

	[lesstif]
		-Fix: correct "top-left" coords of pixmap rendering when flipped
		-Fix: flip (mirror) content of pixmap if displayed on flipped board
		-Add: prepare the code for sparse grid (disable it for now as it's a gtk-only config node)

	[lib_hid_common]
		-Fix: preferences dialog: remove references to pcb-rnd from text printed on GUI

	[lib_hid_gl]
		-Cleanup: remove PRIM_MASK_* code from direct draw: all users got deleted between pcb-rnd 2.1.2 and 2.1.3 back in 2019
		-Split: original drawing backend into draw_direct and the API to draw.h to make room for alternate implementations
		-Cleanup: stencil calls to stencil_gl.[ch]
		-Cleanup: remove low level gl calls from anywhere else but backend code
		-Cleanup: rename colour to color - the codebase follows US English
		-Cleanup: functions with no arguments should be (void) in the low level draw API
		-Cleanup: do not use "static inline", it's not c89; use portable RND_INLINE instead
		-Cleanup: rename solid_rectangle to fillrect: shorter and more consistent with the codebase
		-Cleanup: rename texture_quad to textrect for consistency with other rect calls
		-Cleanup: rename "circular" cap drawing internals to be consistent with the rest of the code base: round cap
		-Cleanup: move stencil op reset from gtk gl to draw low level
		-Clenaup: view (translate+zoom) low level gl setup from gtk side to draw backend (new opengl does not have matrix transformations)
		-Cleanup: abstract push/pop matrix so that gtk doesn't need to do these with gl low level
		-Cleanup: disable a large chunk of dead code - seemingly some old stencil/mask draw code from before layer compositing
		-Cleanup: report error into the message log, not to stdout, when stencil bits are not available
		-Add: support for sparse grid
		-Add: hidgl_set_color() so that hids won't need to use low level draw .h directly
		-Add: error backend: in case no backend is available for rendering, print an error message and provide nop for all calls (better than a segf on NULL function ptr calls)
		-Add: vao backend for non-compat-mode opengl (gtk4), with ES and desktop shaders
		-Add: infrastructure for tracing opengl calls
		-Add: plugin configuration for backend selection logics
		-Add: stencil backends; config bools for disabling each stencil backend
		-Add: support for texture free (releases opengl texture name)

	[lohgid]
		-Fix: make_gc call-through should pass on delegatee hid instead of loghid's own hid - most GUI HIDs will store this pointer and make a check on USE_GC() to make sure no foreign gc is used and loghid would be considered foreign

	[scconfig]
		-Fix: lib_gtk_common is not compiled anymore, disable or depend on lib_gtk2_common and lib_gtk4_common
		-Fix: warn about missing lesstif only if the user explicitly requested it
		-Fix: warn about missing libstroke only if the stroke plugin is explicitly requested by the user
		-Fix: refine no-system-installed-fungw warning to tell it's librnd that needs to be reconfigured
		-Add: refine the gtk2+gl disable warning - opengl is much less generic than it seemed when that message was originally written: every version of gtk and probably every single HID using opengl will have different dependencies
		-Add: more accurate gtk2 vs. gtk4 warnings and notes for all combination of explicit and implicit requests
		-Add: more sophisticated gtk2 vs. gtk4 conflict resolvement: if the user expressed explicit interest in either version on the command line, prefer that one instead of the standard gtk2-over-gtk4 preference
		-Change: switch gtk4 from disable-all to disable so --all=plugin picks it up

	[script]
		-Fix: live script error message: request the user to system-install fungw (not necessarily from source) and reconfigure librnd, not pcb-rnd

librnd 3.1.0 (r33720)
~~~~~~~~~~~~~~~~~~~~~
	[build]
		-Fix: build all objects of gensexpr so that all headers can be installed
		-Fix: install the two missing headers in src_3rd genht
		-Add: install headers of gensexpr when the lib plugin is compiled

	[core]
		-Fix: typo in anyload declaration

		-Add: mark some menu item fields obsolete and scheduled removal

	[dad]
		-Add: publish RND_DAD_SUBDIALOG so that dialg boxes can be build to include caller supplied subdialogs

	[diag_rnd]
		-Import: conf related diag actions from pcb-rnd so that all Ringdove apps have them
		-Import: finish importing diag actions by enabling the plugin and triggering ./configure from tab

	[doc]
		-Add: start documenting wayland specific GUI limitations

	[fsd]
		-Fix: don't segfault in shortcut saving if there's no app dotdir

	[gtk]
		-Split: win resize binding in two, because gtk2 prefers it before show() and gtk4 needs it after show()
		-Add: abstract GDK_MOD1_MASK: gtk4 renamed MOD1 to ALT
		-Add: abstract mouse cursor names (enum or char * or both) to compat layer because gtk4 does it differently
		-Add: internal xpm creation API to allow scaling later

		-Cleanup: replace rnd_hid_gtk_ prefix with rnd_gtk_
		-Cleanup: replace prefix with rnd_gtkg_ in glue API
		-Cleanup: remove _port_ from function names not dealing with ports directly
		-Cleanup: replace GHID_ prefix with RND_GTK_
		-Add: extend the doc to explain the source code split in lib_gtk_common
		-Del: drawing_area_size_allocate_cb() - it's a noop
		-Del: gtkc_widget_get_preferred_height() - no caller
		-Add: API to abstract drawing area configure event, installed on the top window's drawing area
		-Cleanup: rename the dwg resize compatibility event struct to a more generic xy event since it can be reused for mouse as well
		-Change: xy event delivers coords in long (strictly speaking: an int can be 16 bit)
		-Change: do the top window scroll wheel binding through the event xy wrapper for gtk4 compatibility
		-Change: extend the xy event call API to xyz so that mouse scroll wheel key modifiers can be passed back
		-Change: do the top window drawing area enter/leave events using compat.h (for gtk4 transition)
		-Change: do the top window drawing area mouse motion events using compat.h (for gtk4 transition)
		-Cleanup: remove gdk event type dependency from rnd_gtk_note_event_location() so it would work in gtk4 too
		-Change: generalize drawing area event setup, preparing for gtk4
		-Cleanup: switch over preview widget motion, scroll and resize from direct signal binding to compat binding for portability to gtk4
		-Change: do the preview drawing area mouse press/release events using compat.h (for gtk4 transition)
		-Add: generalize event setup so it can be reused independently of drawing widgets
		-Move: resize grip into a separate function; creation to compat layer since gtk4 likely won't have it
		-Move: resize grip xpm from gtk-common to gtk2-common; it won't be supported in gtk4 in any form
		-Move: resize grip: move out from gtk2 topwin - it's a large chunk of unrelated code and may be removed later
		-Update: "who did what" kind of historic banner to reflect changes made for pcb-rnd
		-Split: low level input singal connect/disconnect from common gtk to version-specific gtk as signal handling changed in gtk4
		-Cleanup: use compat layer for top window mouse press/release signals for gtk4 portability
		-Cleanup: figure and pass on modifier keys with mouse button press event from the compat layer so less version-dependent queries are made in gtk-common
		-Cleanup: use version-portable mouse press event for the get location loop
		-Add: compatibility layer for key press event handling
		-Cleanup: top window key presses go through the compatibility layer
		-Cleanup: use compat event bindings for location loop key events
		-Cleanup: switch over preview widget key handling to compat layer
		-Cleanup: bu_command uses the compat layer for key bindings
		-Split: move label wrapper for click bind to the compat layer, it works differently in gtk4
		-Add: compat API for tracking window size changes instead of gtk2-only configure event
		-Add: compat layer for window and widget destroy and delete signals
		-Cleanup: use compat layer for enter event on top window drawing area
		-Split: keyboard translation to gtk version generic and specific halves for gtk4 porting
		-Cleanup: strict match event callback function signature with (void *) user data
		-Cleanup: reclassify private bu_menu functions to static
		-Del: unused rnd_gtk_create_menu_widget_path()
		-Del: remove accel group support from bu_menu: we are not using menu accel for hotkey handline
		-Del: unused action group from global gtk state (we took away hotkey handling from gtk long ago)
		-Cleanup: menu API: don't depend on the custom menu type, pass GtkWidget (gtk4 will use a different widget)
		-Cleanup: move custom menu widget implementation into the .c file to make it private and remove it from the API; gtk4 will not need it
		-Cleanup: move menu toggle callback to private as the glue code always called it with one specific implementation; this removes GtkAction from the API (which is really an internal implementation detail and gtk4 doesn't have)
		-Cleanup: bu_menu: move API doc from .c to .h
		-Cleanup: bu_menu: mark all private functions static
		-Move: bu_menu to lib_gtk2_common - it will be a totally different implementation for gtk4
		-Add: abstract GdkCursorType into compat.h because it's changed in gtk4
		-Move: adjustment tune from ui_zoompan to the compat layer as it has to be done differently in gtk4
		-Add: abstract entry set/get into the compat layer because gtk4 changed the API
		-Add: abstract gtk_entry_set_width_chars() into the compat layer because gtk4 made this more complicated too
		-Del: gtkc_widget_add_class_style() - only the gtk3 port depended on it
		-Split: RND_GTK_KEY() into a gtk2 and a gtk4 variant; only gtk2 needs scconfig detection on this
		-Add: compatibility call for widget background color set - gtk4 doesn't have this (maybe we will need to use css)
		-Add: port wrap-click-bind on labels and picture boxes to use the centralized signal handler macros isntead of manual bindings so they will work with gtk4
		-Cleanup: get rid of end-packing, always use start-packing (in preparation of packing abstraction needed for gtk4)
		-Add: compat API for packing widgets; switch over from gtk2/gtk3 API to the compat API for packing widgets
		-Cleanup: use compat rnd_gtk_color_t instead of GdkColor
		-Add: compat API for frame-set-child
		-Cleanup: use compat api for setting frame child when creating top window
		-Add: abstract creating scrolled windows (gtk2 requires 2 args, gtk4 requires no arg)
		-Add: abstract "get entry widget from combo-box-with-entry" into compat.h because gtk4 does this differently
		-Add: abstract adding a child to a scrolled window - gtk4 requires a specific call for it
		-Add: disable gtk2-specific tree-table workarounds for other versions of gtk
		-Add: abstract tree-table key press binding, event forwarding included
		-Fix: tree table key handler: use librnd's control key modifier to check if control is pressed for ctrl+c
		-Add: abstract copy-text-to-clipboard into compat
		-Add: abstract button child set for picture buttons
		-Add: abstract gtk window destroy: in gtk2 it's widget destroy, in gtk4 a specific window destroy call
		-Add: abstract packing paned children into compat (as gtk4 changed the functions slightly)
		-Add: dad label creation API because truncated/rotated labels are different in gtk4
		-Add: abstract window set id to compat because gtk4 doesn't have it
		-Add: abstract window resize and move - gtk4 has removed this API because of wayland
		-Add: abstract "add main vbox in the content area of a dialog box" mechanism into compat; gtk4 needs different packing
		-Add: abstract show_all(), gtk4 doesn't have that
		-Add: abstract run dialog because gtk4 doesn't have it
		-Move: old, gtk2-only, native gtk file selector from gtk common to gtk2 common - gtk4 won't have a native version at all
		-Add: abstract widget destroy (gtk4 doesn't have it)
		-Add: abstract waiting for destroy events to get delivered (gtk4 removed APIs)
		-Cleanup: move top bar theming to compat layer, hopefully gtk4 can implement it as a no-op
		-Add: abstract gtk_main_quit() (gtk4 removed the API)
		-Add: abstract button set image (not present in gtk4)
		-Add: abstract top window set child (gtk4 doesn't have containers)
		-Cleanup: replace event box with a plain box and remove container based population of it in the top window upper bar - the event box was used earlier to a theme-update trick that was disabled years ago because of risk of unreproduciable crash
		-Add: abstract box that is created only for setting the background color - in gtk2 it was an event box, but there's no such thing in gtk4
		-Cleanup: use compat layer for background color modification in top window alert section
		-Add: abstract widget set focusable
		-Add: abstract scrollbar creation for gtk4 API change
		-Add: abstract left ptr named mouse cursor
		-Add: abstract custom mouse cursor index-to-shape conversion because shape type differs between gtk2 and gtk4
		-Cleanup: remove long unused mouse cursor name defs
		-Add: abstract setting custom mouse cursor call
		-Add: abstract widget-set-cursor
		-Add: abstract cursor warp - gtk4 doesn't have that API because of their bondage&discipline approach
		-Add: abstract wt preview redraw (invalidate)
		-Fix: preview widget: use compat layer for making the widget focusable
		-Add: abstract one more level of preview expose event as it's very different in gtk4
		-Add: abstract main and quit because gtk4 had to change the API on this too
		-Add: abstract parse arguments callback: gtk app initialization changed in gtk4
		-Add: abstract low level top window creation call, gtk4 has it differently
		-Add: abstract window origin query
		-Move: top window drawing update to compat layer as gtk4 changed render mechanism
		-Change: get_origin abstraction: pass on a widget, not a window, let the version-dependent backend figure how to get the window for that
		-Add: abstract clipboard get text, it's going to be different in gtk4
		-Add: abstract beep
		-Add: abstract explicit iterate call
		-Add: abstract benchmark (gtk4 needs to do flushes differently)
		-Add: abstract opening popup menus
		-Add: abstract mod1 mask apple fix - gtk4 likely won't need it
		-Add: abstract checkbutton set
		-Add: abstract check button signal name
		-Add: abstract check button get
		-Add: abstract setting scrollbar value - gtk4 doesn't have "range" for adjustment
		-Add: abstract scrollbar getvalue
		-Cleanup: rename adj to scb because our internal API is about scrollbars, adjustment is just the gtk2 implementation
		-Fix: zoom adjustment compat API: expect a scrollbar because gtk4 won't have ranges
		-Add: workaround button minimal size and image border (in gtk4) for image buttons
		-Fix: when adding dock box (not frame), don't make it expand: the main drawing area should take all extra space
		-Fix: pack attribute dialog widgets with alignment 'start' instead of 'fill' in the non-expfill direction to match DAD alignment expectations
		-Move: gtk gl common code from gtk2 gl hid to lib_gtk_common so that it is available for gtk4 as well
		-Fix: don't include gtk2-specific header in common code
		-Cleanup: don't hardwire gtk2_gl where hid is easily available
		-Fix: remove gtk2_gl direct reference where it can be avoided
		-Cleanup: remove gtk2 hid hardwirings from the common gtk gl code
		-Move: color-to-name function from common to gtk-version-specific plugin as color type changed from gtk2 to gtk4
		-Add: abstract the whole scrollbar+adjustment creation code from top-dialog - gtk4 needs it differently to work around yet another gtk4 bug
		-Change: generalize rnd_gtk_menu_widget() into rnd_gtk_menu_popup_pre(); in gtk4 it won't return a widget as popup widgets are not yet created
		-Fix: port color literal (gtk2 uses 16 bit int, gtk4 uses float 0..1)
		-Add: unify top window scrollbar thickness on default theme
		-Fix: use portable check button get active in DAD code for bools
		-Fix: symmetric keyboard unbinding macro for gtk4 event controller
		-Fix: symmetric mouse button unbinding macro for gtk4 event controller
		-Fix: symmetric gtk window destroy unbinding macro for gtk4 event controller
		-Add: set paned position on widget creation: workaround for async widget creation (gtk4)

	[hid]
		-Add: rnd_hid_fileselect(), wrapper aroud hid->fileselect that long term will obsolete hid->fileselect()
		-Cleanup: move hid->fileselect() description comment to rnd_hid_fileselect() and mark hid->fileselect() obsolete
		-Cleanup: use rnd_hid_fileselect() instead of direct hid call

	[hid_gtk2_gl]
		-Fix: uninitialize menu on exit
		-Del: long unused subcomposite start/end calls
		-Del: remove long unused dummy functions for line cap angle and faded color
		-Cleanup: split up main and preview expose gl code, move out the common gl context initialization code into a separate function (removes code dup)
		-Cleanup: remove unused variable from crosshair rendering
		-Change: crosshair draw function replaced interactive gl functions with vertex array
		-Change: draw the background using vertex array instead of interactive GL functions
		-Change: ghid_gl_draw_bg_solid_color() shouldn't take hidlib but x1,y1, x2,y2 because it's a generic low level gl rectangle draw function really
		-Split: preview expose code into a gtk2 specific and a common (zoom-setup + gl draw) part
		-Split: gtk2-specific code from common gtk-gl code
		-Add: comment to explain why ghid_gl_set_line_cap() is empty

	[lib_hid_common]
		-Import: generic part of preferences window, including the last four tabs from pcb-rnd so thye are available in all ringdove apps
		-Cleanup: remove the temporary Rnd_ prefixes, use rnd_ for the public API
		-Fix: preferences: do the initialization with 0 app specific tabs on the first call to Preferences() action if the app did not initialize - this makes it easier and safer to use preferences dialogs for simple apps that don't have specific preferences tabs

	[lib_hid_gl]
		-Change: replace GL_QUADS with GL_TRIANGLE_FAN since GL_QUADS is deprecated
		-Change: direct-draw a rectangle using vertex array instead of interactive GL functions
		-Move: expose init and Z_NEAR from lib_gtk2_gl (this is generic gl utility code useful for any gl rendering)
		-Move: background filled rectangle draw function from gtk2_gl
		-Cleanup: use line cap enum type for line end cap instead of int to make the API self-documenting
		-Cleanup: prefix Z_NEAR to avoid namespace pollution
		-Split: low level crosshair draw moved to generic gl draw code - it would be used independently of the toolkit

	[scconfig]
		-Add: include full version string in config.h so apps can print it for easier debugging
		-Add: explicit variable for libarchdir in librnd.mak
		-Add: gtk4 detection logic
		-Fix: don't let both gtk2 and gtk4 configured as builtin; porefer gtk2 over gtk4 for now

~~~~~~~~~~~~~~~~~~~~~
	[core]
		-Fix: don't crash on NULL string in rnd_conf_print_native_field() (ConfDump() action)

		-Add: define what exactly the CHANGE_CB does for a tree

	[gtk]
		-Cleanup: util_watch doesn't depend on in_mouse
		-Fix: tree table: add the tree view widget directly in the scrolled window so they can interact; this way moving the cursor will automatically update scroll
		-Fix: do not omit tree table when RND_HATF_SCROLL is not set (did not set wltop)
		-Fix: uninitialized pixels in custom mouse cursor imported from xbm smaller than 24x24
		-Fix: DAD tree click release should stop gtk from double-opening the given subtree
		-Fix: more robust fix for subtree expand when the arrow is clicked: let gtk handle the arrow
		-Fix: tree table enter_cb is called only on double click or enter on a row
		-Add: implement the subdialog HATT

		-Add: mark RND_HID_FSD_IS_TEMPLATE obsolete and schedule removal
		-Add: fileselect descr argument is not really used at the moment
		-Add: API for optional DAD widget poke

	[hid_gtk2_gl]
		-Fix: gdk_color_parse() doesn't handle alpha, remove it when it is present in the input color string

	[lesstif]
		-Fix: remember if popup is open and don't lose get_xy coords (crosshair coords) so that actions triggered from the right context popup won't ask for new coords
		-Fix: close the popup menu when an item is selected and mark the popup inactive after the corresponding action finished
		-Fix: tree table: call DAD CHANGE_CB on enter pressed
		-Fix: tree table: double click on entry should call change cb
		-Fix: memory handling error on HATT_STRING set()
		-Add: HATT_SUBDIALOG implementation

	[lib_hid_common]
		-Import: plus and minus xpm's from pcb-rnd (layer selector)

	[scconfig]
		-Fix: do not accept lesstif installation if it doesn't have XmEXTERNAL_HIGHLIGHT (required for picture buttons and toggle buttons)

	[script]
		-Fix: use the 'selected' callback instead of the 'changed' callback for DAD_TREE() because the API around 'changed' is not clear

librnd 3.0.1 (r32954)
~~~~~~~~~~~~~~~~~~~~~
	[build]
		-Fix: running 'make' in any plugin changes to the right source directory to rebuild that plugin

	[core]
		-Fix: change internal GUI HID load mechanism: do not autoload HID plugins, but try to selectively load only the ones that are requested by the user or preferences; when there is absolutely no preference, load them all, but make sure to load lesstif first because it is broken and order of -lXm and -lXt matters even in dynamic linking

	[dad]
		-Fix: coord spin: print values to at most 6 decimal digits to reduce rounding errors

	[doc]
		-Add: link edakrill from the -rnd box
		-Add: mention genht and fungw in INSTALL for extended user scripting

	[gtk_common]
		-Fix: implicit declaration of tool function in dlg_topwin

	[hid]
		-Fix: don't ever fall back to automatically pick a GUI hid if it's marked hidden

	[lib_gtk_common]
		-Fix: implicit declaration of tool calls in bu_menu
		-Add: center view after the initial zoom-to-extent

	[lib_hid_common]
		-Fix: Zoom() without arguments is "auto zoom" which should zoom to extent _and_ center (pan)

	[loghid]
		-Fix: do not let loghid hook itself (would lead to infinite loop)
		-Fix: sanity check on all loghid calls to avoid infinite loop (loghid calling loghid)
		-Fix: mark loghid's GUI sniffer hidden so it's never picked up as default/fallback HID

	[poly]
		-Fix: excess semicolon ruined strict C89 validity

	[scconfig]
		-Cleanup: const correctness: don't make char * const if it's malloc'd and free'd

	[tests]
		-Fix: don't mind if some files are already removed in make clean's make uninstall of the local librnd installation


librnd 3.0.0 (r32916)

	[action]
		-Add: API CHANGE: introduce RND_APP_PREFIX() for RND_ACT_FAIL() and other ACT macros to know the host application namespace prefix
		-Cleanup: rename from pcb_act* prefix to rnd_act* prefix for clarity and namespace

	[anyload]
		-Add: spare fields

	[conf]
		-Fix: don't crash if native node is queried before the hash is initialized
		-Fix: don't crash if app didn't specify user conf dir
