+rxvt-unicode changelog <= google-friendly title
+
+TODO: xcopyarea pass broken, fix and improve
+TODO: event mechanism that replaces on_user_command with something more scalable.
+TODO: slipwheeling needs a keyboard grab to get key release events.
+TODO: overlays collide with the way the out-of-focus cursor is being drawn
+TODO: "slow" rendering mode for bidi and scripts, pango!
+TODO: read property sequence is broken with respect to utf-8 etc.
+TODO: slow drag selection on remote display - other things seem fast (rxvt illness, motion hints?)
+TODO: better resource handling for tabbar in -pe tabbed.
+WISH: investigate -pe tabbed -g 80x25 being 23 not 24 or 25 lines
+      => when setting the constraints, the wm might (correctly)
+         resize the outer window, which might result in a smaller window overall.
+         or something like that. guys, send me a patch.
+WISH: coloured pastebin
+WISH: load system-wide config file even if we don't have one
+WISH: look into XAddConnectionWatch, does anybody need that?
+DUMB: support tex fonts
+TODO: perl-shell-window? perl-unix-socket?
+TODO: command line editing when icanon?
+TODO: split ROW into a ROW_fast (0..total*2-1) and ROW macros?
+TODO: catch exceptions when calling perl hooks
+TODO: xdbe
+TODO: optimise bg reeval for resize for common patterns (pixmap bigger than window?)
+TODO: pack rxvt_fatal messages into the exception object
+TODO: load must not cache, but global image cache must be cleaned
+TODO: description into --help output?
+TODO: rxvt -help => (see rxvt-XXX(1))?
+TODO: xor_rect should shift right
+TODO IMPL: recalc bg only when not fully covering (no alpha, repeat|extend etc..)
+
+TODO IMPL: colour-change event with index
+TODO IMPL: recalc bg always on bg colour change
+
+TODO: document typical actions in rxvt.1.pod keysyms
+TODO: warn with a graphical message when env has been modified
+TODO: c&c perl socket via daemon-ext mechanism
+TODO: simplify extension metainfo cache, cache on disk
+TODO: URxvt::Ext::Name installs urxvt ext name and provides pod/manpage for URxvt::Ext::Name
+TODO: üpixel droppins idenrasm,ll,scrollup
+TODO: cuu/cud and probably others default to 1 when arg is 0, not just missing, in xterm/vt102, but not in rxvt
+TODO: implement xterms nih 1006 mouse mode because the fud campaign against urxvt's 1015 mode works.
+
+TODO: confirm-pastes should check for any ctl
+TODO: fix ESC G reply forever, or simply completely disable it?
+	- work around API change breakage in perl 5.28, based on a patch by
+          Roman Bogorodskiy.
+	- improved security: rob nation's (obsolete) graphics mode queries
+          no longer reply with linefeed in secure/default mode.
+	- ISO 8613-3 direct colour SGR sequences (patch by Fengguang Wu).
+	- xterm focus reporting mode (patch by Daniel Hahler).
+	- in some window managers, if smart resize was enabled, urxvt
+	  erroneously moved the window on font change - awesome bug
+	  #532, arch linux bug ##34807 (patch by Uli Schlachter).
+	- fix urxvtd crash when using a background expression.
+	- properly restore colors when using fading and reverse video
+	  is enabled while urxvt is focused and then disabled while it
+	  is not focused, or vice versa (patch by Daniel Hahler).
+	- fix high memory usage when an extension repeatedly hides and
+	  shows an overlay (reported by Marcel Lautenbach).
+	- the old bg image resources are now provided by the background
+	  extension, and perl is thus required for bg image support. No
+	  configuration change is needed: urxvt autoloads the background
+	  ext if any bg image resource/option is present. The old bg image
+	  resources are also now deprecated; users are encouraged to
+	  switch to the new bg image interface (see man urxvt-background).
+        - expose priv_modes member and constants to perl extensions
+          (patch by Rastislav Barlik).
+
+9.22 Sat Jan 23 21:07:33 CET 2016
+	- NOTICE: this release updates terminfo.
+	- add terminfo capabilities for various ctrl and shift-ctrl key variants
+	  (patch by Sebastian Schmidt).
+        - fix longstanding core font encoding bug where some character
+          ranges could not be mapped from unicode to the font: affected
+          encodings are big5, gb2312, iso8859-8 (hebrew), jis0201 and
+          ksc5601 (reported by Mikachu).
+        - fix crash when the number of columns is 1 and a 0 width character is inserted
+          (reported by Kuang-che Wu).
+        - fix a crash when parsing an invalid color specification (reported by Kuang-che Wu).
+        - fix a buffer overflow in font name parser (reported by Kuang-che Wu).
+	- do not start blinking cursor if the window is unfocused (reported by
+	  Devin J. Pohly).
+	- change the width of underline and i-beam cursor to 2 pixels (based on
+	  a patch by Omar Sandoval).
+	- add pointerShape resource to change the mouse pointer shape
+	  (based on a patch by Brian Watson).
+	- a keysym resource for a key which is already bound to an
+	  action now properly rebinds the key.
+	- do not report mouse motion events if Shift is active (patch by Daniel Hahler).
+	- put the alpha component last in responses to OSC color queries
+	  (patch by Benjamin Herr).
+	- the key_press hook is now invoked before processing the
+	  event, as documented. This change was done in 9.21 but not
+	  announced and fixes debian bugs #511377, #531751 and red hat
+	  bug #1105069. Note that this change breaks a few scripts,
+	  such as mark-yank-urls, which rely on the previous buggy
+	  behaviour that urxvt processes the event (in particular
+	  keysym bindings) before invoking the hook.
+	- the tabbed extension now properly refreshes the active tab
+	  on a key press when the mouse pointer is outside the terminal
+	  window.
+	- add 'lookup_keysym' perl method to lookup the action bound
+	  to a key combination.
+	- a key combination bound to 'matcher:select' can now be used
+	  to cycle through the matches in matcher.
+        - change perl integer accessors (->width et al.) into mutators.
+
+9.21 Wed Dec 31 14:50:03 CET 2014
+	- the "moa redraw 8-bit british vintage colour management" release.
+	- NOTICE: this release updates terminfo.
+	- fix pixel droppings on overdraw when a secondary core font has the
+          same height but different ascent.
+        - implement cvvis in terminfo as blinking cursor, to distinguish it
+          from cnorm (emacs uses cvvis which is commonly a blinking cursor).
+        - when xft support was compiled in, colour queries erroneously returned
+          premultiplied values, this also affected internal queries, for example
+          when calculating faded colour. alpha is now divided out when possible,
+          which is more correct but loses colour resolution.
+	- add DECSCUSR xterm extension to set the cursor to a vertical bar.
+	- add 'extension:string' action, and associated on_action perl
+	  hook, for keysym resources that invokes actions provided by
+	  perl extensions. The 'perl:string' action and
+	  on_user_command hook are deprecated but still supported.
+	- add 'builtin-string' action for keysym resources that restores string
+	  mappings for keys that have predefined actions in urxvt.
+	- add -k option to urxvtc for killing the daemon process.
+        - document urxvtd's -e/--eval option that was implemented in 9.16,
+          but not documented.
+	- add -dockapp option to make the wm treat urxvt as a dockapp.
+	- add -mc option and multiClickTime resource to set the maximum time
+	  between multi-click select events (patch by Joe Peterson).
+	- new 'eval' extension to evaluate arbitrary perl code with keysym
+	  bindings. The extension also provides methods that implement basic
+	  actions, such as pasting selections and scrolling.
+	- the macosx-clipboard and macosx-clipboard-native extensions have been removed.
+	- kuake extension now uses the kuake.hotkey resource to specify the hotkey.
+	- new 'matcher:select' mode of matcher to iterate over the matches with the keyboard.
+	- the 'matcher:list' feature of matcher now honours the launcher
+	  associated to a matched pattern.
+	- speed-up matcher underlining on very long lines (reported by Edward Z. Yang).
+	- fix up/down commands of searchable-scrollback so that they always move
+	  to the previous/next logical line with a match, if any.
+	- searchable-scrollback resource has been deprecated (use keysym instead).
+        - extension parameter passing is deprecated (use resource mechanism instead).
+        - upgrade to GPLv3 (see COPYING).
+	- compile out of the box on Solaris 10, again.
+        - fix height and position of the stippled area in next scrollbar (patch
+          by Thomas Otto).
+        - fix off-by-one bug causing the iso14755 window not to jump out of the
+          way properly.
+	- fix crash that may happen if a lib to which urxvt is linked to calls setenv.
+	- fix memory leak in special_{encode,decode} perl methods.
+	- fix refresh bug that occurs when reverse video is set on a cell
+	  containing a space and with the same bg and fg colour, red hat bug
+	  #830236.
+        - fix crash that may happen if an x error is received after a terminal
+          window/popup has been destroyed already.
+        - removed superfluous 0 digit from sgr terminfo sequence.
+        - greatly improve colour allocation on colour-starved pseudocolour
+          displays to avoid read-write cells instead of simply failing
+          (this is only relevant for antique 8bpp frame buffers).
+        - do not free fade colours when not doing fading (this is likely
+          only relevant for antique 8bpp frame buffers).
+	- do not specialcase 2 or 4 colour visuals, leading to
+          simpler and actually more correct code.
+        - hopefully no longer leak colours on !truecolour visuals.
+        - use consistent method names (scr_recolour => scr_recolor).
+        - use simpler (but slightly less bogus) formula for nearest
+          colour choice (this is likely only relevant for antique 8bpp
+          frame buffers).
+        - remove fallback behaviour when initialising colours - the
+          behaviour was inconsistent between startup vs. later and
+          was only effective when valid colours couldn't be allocated.
+
+9.20 Sat Apr 26 16:22:27 CEST 2014
+        - (libptytty) fix bug that prevented urxvtd from writing utmp
+          entries when using --fork (reported by Ryan Kavanagh).
+        - security bugfix: window property values could be queried even
+          in secure mode (reported by Conor McCarthy).
+	- fix build when perl is enabled and fading is disabled.
+	- fix regression that broke continuous scrolling when pressing
+	  and holding the scrollbar up or down button, gentoo bug #493992.
+	- increase the maximum length of a command sequence to 32k bytes,
+          to allow longer OSC sequences (previous limit was 2k).
+        - new Ctrl-Meta-c and Ctrl-Meta-v bindings to interact with
+          the CLIPBOARD selection.
+        - new extension: selection-to-clipboard.
+        - the extensions macosx-clipboard and macosx-clipboard-native
+          are deprecated and will be removed in the next release.
+          Support for the clipboard on OS X can be more generally
+          enabled by setting the XQuartz preference to sync the OS X
+          pasteboard and the X11 clipboard.
+
+9.19 Sun Oct 27 17:16:07 CET 2013
+	- work around perl 5.18.0 breakage in tabbed extension
+          (reported by Karol Blazewicz) and in pod (Dominic Hargreaves).
+	- fix regression that caused the double-click word selection to
+	  erroneously include a tab on the left of the selected word.
+        - implement FOCUS variable and focus_fade function in background
+          expression, to allow focus-sensitive background images.
+	- add support for the set cursor style (DECSCUSR) control
+	  function.
+	- honour cursorColor also when the cursor style is underline.
+        - export some Color_xxx constants to Perl.
+
+9.18 Sun Mar 24 15:33:35 CET 2013
+	- fix regression that caused artifacts on resize.
+
+9.17 Fri Mar  1 13:46:08 CET 2013
+	- add shade operator in background perl extension.
+        - avoid starting or ending the selection in the middle of wide
+          characters to avoid artifacts (reported by Tiago Resende).
+	- fix artifacts that may occur if the character in the cursor
+	  cell has width > 1 (reported by Tiago Resende).
+	- fix regression that causes artifacts on scrolling if
+	  saveLines is 0 and the window is resized (reported by Bert
+	  Münnich).
+	- fix build when perl is enabled and pixbuf and transparency
+	  are disabled.
+
+9.16 Thu Dec 27 11:56:43 CET 2012
+	- the "so much new stuff your eyes will pop out" release.
+        - INCOMPATIBLE CHANGE: renamed urlLauncher resource to url-launcher.
+	- fix processing of DEC private mode save sequences (patch by Patrick
+	  Hemmer).
+        - perl extensions now have their own manpages, installed as urxvt-NAME(1),
+          e.g. urxvt-background(1) - see urxvt-extensions(1) for a list.
+	- fix disabling of cursor blink with the option-popup menu (based on a
+	  patch by Jan Larres).
+	- the font height is not augmented anymore when lineSpace is non zero.
+	- fix "new pagemap" vs. "delete pagemap" mismatch ([] vs. non-[]),
+          as diagnosed by clang.
+	- fix height mismatch between active and inactive cursor when
+	  lineSpace is non zero (patch by Stanislav Seletskiy).
+        - make it compile with LOCAL_X_IS_UNIX again (reported by
+          nickfailure@gmail.com).
+        - completely redone background pixmap support - users can now
+          specify arbitrary expressions (And programs) that calculate
+          new terminal backgrounds. see the urxvt-background manpage
+          for details.
+        - xrender is now required for background pixmap support.
+        - perl extensions can now provide commandline switches and resources
+          which show up in -help etc.
+        - iso14755 51 mode window now displays row and column.
+        - implement a -visual switch and move that and -depth to frills, also
+          warn when we can't get the requested visual.
+        - new env variable: RXVT_PERL_LIB.
+        - allocate all screen memory in one go and let the virtual memory
+          subsystem sort it out. this simplifies code, improves access
+          locality, saves a bit of ram and makes things a bit faster, too.
+	- remove support for libafterimage.
+        - update to CVS version of libev, for a whopping 11kb size decrease.
+        - do not ship yet another copy of ecb.h, use the one in libev or
+          libptytty instead.
+        - selectively mark some methods as cache-hot/cache cold, which
+          might speed up execution but definitely decreases codesize.
+        - Fix regression that prevented the scrollbar trough color
+          from being applied (reported by Derek B. Noonburg).
+        - Fix the scrollbar size for rxvt style (patch by Mark Robinson).
+
+9.15 Sat Jan 21 13:36:56 CET 2012
+	- remove "using namespace std" because clang erroneously
+          thinks thats an error.
+	- finding a matching font (e.g. bold version of the base font)
+	  was broken (reported by Eamon Walker).
+	- fix parsing of bg image styles. They really work now.
+	- fix blurring of bg image borders when using xrender.
+	- fix xrender blur on common xrender implementations that do
+	  not behave correctly when the same pixmap is used as source
+	  and destination in composite operations.
+	- fix regression that caused tabbed to compute the wrong size
+	  for tabs.
+	- allow again an empty suffix in a keysym list spec (patch by
+	  Sung Pae).
+	- unsupported support for sun studio's CC added.
+	- fix -C option on solaris.
+
+9.14 Wed Dec 21 18:40:33 CET 2011
+	- INCOMPATIBLE CHANGE: the urxvtd default socket path is now
+	  $HOME/.urxvt/urxvtd-<nodename>.
+	- INCOMPATIBLE CHANGE: the "list" keysym expansion now requires
+	  loading of the "keysym-list" perl extension.
+	- INCOMPATIBLE CHANGE: A scale value of 0 in the bg image
+	  geometry no longer enables tiling, so as to make it possible
+	  to disable both scaling and tiling.
+	- overhaul of the bg image operations. The old operations have
+	  been deprecated in favour of elementary operations and
+	  styles built on top of the new operations and scale/position
+	  settings. (Emanuele Giaquinta).
+	- support for libafterimage is deprecated and will be removed
+	  in the next release.
+	- fix a crash caused by selection_check not properly resetting
+	  out-of-bounds mark values (can happen when extending a selection
+	  while scrolling up in curses programs for example).
+	- do not move the selection when scrolling up and the selection is
+	  outside the scrolling region (Emanuele Giaquinta).
+	- fix display of bold bright black (reported by Ben Winslow).
+	- fix memory leak when urgentOnBell is set (patch by Nathaniel
+	  Filardo).
+	- fix a redraw bug that occurs when a bg pixmap is set and the
+	  wm does not honour the size hints set by urxvt. Now urxvt
+	  forces the size of the terminal window to be a multiple of
+	  the cell size.
+	- sanitise the argument of SD / SU sequences. Fixes a possible
+	  crash when the argument is big enough, red hat bug #711137
+	  (Emanuele Giaquinta).
+	- correctly split long lines when scrolling.
+	- urxvt now looks for perl extensions also in $HOME/.urxvt/ext.
+	- add bell-command perl extension to execute a command when a
+	  bell event occurs (Ryan Kavanagh).
+	- add set_urgency perl binding to set/reset the urgency hint.
+	- consume button release event in matcher (exg).
+	- keyboard accessible list of recent matches in matcher
+	  (Bob Farrell).
+	- properly process 'keysym' sequences in tabbed when using
+	  'focus follows mouse' and the focus is on the main window
+	  but not on the active terminal window (patch by Martin
+	  Pohlack).
+	- support for the freedesktop startup-notification protocol (patch by
+	  Michael Stapelberg).
+	- the direction of VPR and VPB commands was reversed.
+	- fix alignment of inherited root pixmap when it is a different size
+	  than the root window and the terminal window is off the left or top
+	  edge (Mikachu).
+	- make $self visible in "eval perl expression" popup action, also
+	  handle exceptions better.
+	- fix parsing of '-e' when it occurs as an option argument, such as in
+	  'urxvt -title -e' (Emanuele Giaquinta).
+
+9.12 Wed Jun 29 14:34:28 CEST 2011
+	- fix regression in processing of SelectionNotify events.
+	  urxvt would fail to request a selection if the owner did not
+	  support the UTF8_STRING target.
+	- fix rendering of double width chars in certain circumstances, more
+	  likely to happen if urxvt is compiled with 256 colors support as
+	  urxvt runs out of fonts much earlier then. Fixes gentoo bug #358151
+	  (Emanuele Giaquinta).
+	- restore support for 'list' syntax in keysym resources (requested by Sung Pae).
+	- always premultiply colour values - while this increases differences between
+	  core fonts and xft, it is "more correct" in practical situations.
+	- disable PTYTTY_REENTRANT option - not needed for urxvt and saves a bit of code.
+	- remove lucidatypewriter from the list of fallback fonts, it was the only
+	  non-xft non-cellfont in the list anyway.
+
+9.11 Mon May  2 10:34:46 CEST 2011
+	- fix compilation on GNU/Hurd, debian bug #624736.
+	- remove 'list' syntax for keysym resources, as it serves no useful purpose.
+	  If you need it, poke us and provide a use case.
+	- fix alpha channel support. Premultiply alpha in colours if the visual
+	  supports an alpha channel, as xrender expects premultiplied alpha
+	  (Emanuele Giaquinta).
+	- fix reply to a selection request sent by an obsolete client
+	  such as syncterm (patch by Marcin Cieslak).
+	- fix crash when the window is resized and the overlay is active
+	  (Emanuele Giaquinta, reported by Ryan Kavanagh).
+	- match character-wise rather than byte-wise in selection
+	  extension again. perl 5.8.9+ is required to avoid extreme
+	  slowdowns. Fixes debian bugs #523072, #616463.
+	- fix a possible crash if the INCR transfer process for a
+	  selection property timeouts and at least one chunk is
+	  received. (Emanuele Giaquinta)
+	- work around a memory corruption bug in xorg's XrmSetDatabase (apparently
+	  broken since http://lists.freedesktop.org/archives/xorg-commit-diffs/2004-March/000239.html).
+	- fix memory corruption bug when custom command sequences bound to keys
+	  were injected into an already-full pty input buffer.
+	- gdk-pixbuf is autodetected by default and preferred over libafterimage.
+	- do not prepend a newline to the selection text when the starting line
+	  of the selection is not highlighted (Emanuele Giaquinta).
+	- don't swap perl env with real env, save and restore it, just in case
+	  we ever get recursive perl invocations. also saves a bit of codespace
+	  with gcc.
+	- fix various memory leaks (Emanuele Giaquinta).
+	- fix typo in kIC terminfo capability, debian bug #446444.
+	- document 'thickness' resource.
+	- fix debian bug #504817, to the extent possible.
+	- try to detect byte order at compile time, saves a couple of
+	  hundred bytes, if your compiler is smart enough.
+	- add support for previewing the pasted data in confirm-paste
+	  (Emanuele Giaquinta).
+	- added "newlines to spaces" option in selection-popup.
+	- actually enabled solaris event ports backend (was disabled by accident).
+	- revert to 38400 baud max., mission accomplished.
+	- no longer create scary "pty_fill: PLEASE REPORT" message, instead,
+	  silently drain the input (problem is well understood now).
+	- no longer swallow rob nation's own graphics mode commands.
+
+9.10 Mon Dec 13 17:43:52 CET 2010
+	- the "schmorp=north korea dickey=south korea" release.
+	- INCOMPATIBLE CHANGE: make OSC 20 simpler and more correct
+	  (Emanuele Giaquinta).
+	- if options were compiled out, this could lead to the option
+	  count to be defined wrongly. This is likely behind the
+	  failures with gcc 4.5.
+	- explicitly depend on fontconfig and xrender when xft support
+	  is enabled. Although the public Xft api uses types from
+	  both, in Xft 2.2.0 these libs are private
+	  dependencies only thanks to an idiotic behaviour of
+	  pkg-config that was added to workaround cases like this one.
+	  Fixes linking when using GNU ld with --as-needed or GNU gold
+	  (based on patch by Jan Palus).
+	- fix minor memory leaks in urxvt and urxvtd.
+	- fix regression in urxvtd that prevented options from being correctly
+	  set (reported by Michal Vaner).
+	- implement xterm's horribly broken 1005 mouse reporting mode,
+	  and an alternative 1015 mode that works in non-utf-8 locales
+	  and has fewer limitations.
+	- fix a possible bug where mouse notifications didn't work after
+	  startup for the upper left corner.
+	- implement our own pixbuf to pixmap rendering to get rid of
+	  dependency on buggy gdk-pixbuf-xlib. Only truecolor visuals
+	  are supported (Emanuele Giaquinta).
+	- apply tinting before shading when both operations are requested.
+	  Previously they were intermixed when lightening and the result
+	  was inaccurate and confusing. Note that now a black tint yields a
+	  completely black image, regardless of shading (Emanuele Giaquinta).
+	- avoid spurious redraws of the bg image when bg is transparent or
+	  when using 'root' mode (Emanuele Giaquinta).
+	- fix build on XFree86.
+	- dynamically number options according to compiletime requirements.
+	  For the extra saved byte. Or so. Yay.
+	- start options at one, not zero. Wastes a bit per terminal. Maybe.
+	  saves 50 instruction bytes. Possibly.
+
+9.09 Sat Nov 13 01:39:07 CET 2010
+	- NOTICE: this release updates terminfo/termcap.
+	- the bestest release ever.
+	- it was verified that urxvt handles µ and μ correctly.
+	- add support for blending and blurring with XRender (Emanuele Giaquinta).
+	- add support for using gdk-pixbuf as image backend (Emanuele Giaquinta).
+	- cleanup and minor fixes of the image code (Emanuele Giaquinta).
+	- new perl extension "confirm-paste" (Emanuele Giaquinta).
+	- new on_tt_paste perl hook and tt_paste perl binding (Emanuele Giaquinta).
+	- new on_bell perl hook (Emanuele Giaquinta).
+	- searchable-scrollback no longer ignores the first line
+	  (Emanuele Giaquinta).
+	- properly set VSTATUS in termios for *BSD (reported by Ed Schouten).
+	- fix utmpx detection on upcoming FreeBSD 9.
+	- Use COMPOUND_TEXT encoding for WM_NAME/WM_ICON_NAME value when it
+	  is not fully convertible to STRING (patch by James Cloos).
+	- fix a buffer overflow that would cause wrong key sequences to
+	  be generated for numpad keys (introduced in 9.05).
+	- fix definition of sgr0 to work around limitations in luit.
+	- extend ISO 14755 5.4 mode to also print the font name of the
+	  characters other than first one in the selected cell
+	  (Emanuele Giaquinta).
+	- new iso14755 option to disable ISO 14755 at runtime
+	  (Emanuele Giaquinta).
+	- make sure pagewise scrolling scrolls at least one line
+	  (found by Mikachu).
+	- remove deprecated OSC 18 / 19 and make OSC 17 / 19 apply to
+	  highlightColor / highlightTextColor (Emanuele Giaquinta).
+	- add highlightTextColor resource to change the foreground colour of
+	  highlighted characters (Emanuele Giaquinta).
+	- make highlightColor apply also to selected cells with reverse video
+	  but not to non selected cells with reverse video (Emanuele Giaquinta).
+	- remove colorRV resource (it was enabled only with frills off).
+	- fix numlock handling, the most longstanding bug to date (Emanuele Giaquinta).
+	- reduce the number of custom bits to 4, to make room
+	  for 256 colours.
+	- add support for 256 colors (Emanuele Giaquinta, Marc Lehmann).
+	- add rxvt-unicode-256color terminfo and use it by default in 256 colors mode.
+	- update rxvt-unicode terminfo to state 7744 colour pairs to cover all
+	  88*88 possible pairs.
+	- actually added macosx-clipboard-native, which should have been in
+	  the 9.07 release but had been forgotten.
+	- fix hang if DECAWM is not set and there are not enough columns to insert a
+	  character (Emanuele Giaquinta).
+	- cub1 ("backspace") will now respect wrapping when past the rightmost column,
+	  working around a shortcoming of most tty line discipline's line editing.
+	- add support for grabbing the clipboard selection and extend
+	  selection{_clear,_grab,} perl bindings to optionally work
+	  on the clipboard selection (based on patch by Dana Jansens).
+	- no longer force CERASE to BACKSPACE - use the system default. affects
+	  default value for VERASE only when no compatible setting for
+	  backspacekey was given.
+	- use higher than 38400 baudrate setting, if detected.
+	- erase screen would clear to the wrong background when blinking
+	  was enabled (which selects high intensity under some circumstances).
+	- scr_kill_char didn't touch the line.
+	- upgrade and port to libev-4.01.
+	- enabled solaris event ports and kqueue backends (if available).
+
+9.07 Wed Dec 30 07:07:18 CET 2009
+	- port to glibc-2.10 changes (strchr etc. returning const char *
+	  in C++), based on patches by Milos Jakubicek and Oliver Mader.
+	- the binary search algorithm to find precomposed characters
+	  was faulty, skipping some possible combinations (found by
+	  Mikachu).
+	- new -letterspace option, patch by Mark H. Wilkinson.
+	- enable --mlock option for urxvt with frills on
+	  systems supporting it (patch by Russell Harmon).
+	- urxvt did not compile without frills enabled
+	  (analysed by Matthew Rosewarne).
+	- correctly reset the mbstate after an illegal
+	  input sequence when handling terminal output (Emanuele Giaquinta).
+	- avoid redrawing wide characters with combining enabled on every
+	  refresh (reported by Mikachu).
+	- fix a typo preventing the ISO-646.1991 character set from being
+	  recognized (http://achurch.org/patch-pile/).
+	- better warning for x11 font encoding detection failures, also,
+	  try to deduce encoding from both font properties and name
+	  (adapted from http://achurch.org/patch-pile/).
+	- resizing the window with the scrollbar disabled via the escapes
+	  sequence could make the window bigger again (Mikachu).
+	- make sure the alignment for fd passing control messages
+	  is correct and work around some NetBSD issues (Taylor R Campbell).
+	- update to libptytty 1.3.
+	- replace macosx-clipboard by a nicer version by Reza Jelveh, and move
+	  the old version to macosx-clipboard-native.
+	- document the -uc option (Emanuele Giaquinta).
+	- assertions in libev are now enabled depending on frills.
+	- update AnyEvent implementation to version 5.23 API.
+	- work around arrogant bsd idiocies again: netbsd spills the default
+	  namespace with lots of symbols "for gnu/gcc compatibility" even
+	  though neither of them does it, and then calls the rest of the world
+	  in need of fixing. go figure.
+	- on_keyboard_command is on_user_command (patch by Michael Witten).
+	- setting the selection from perl will now reset the selection screen
+	  to the current screen. the screen can be manipulated using
+	  the new ->selection_screen method.
+	- implement --enable-assert configure option and get rid of DEBUG_STRICT
+	  (based on patch by Emanuele Giaquinta).
+	- fix printpipe data output (patch by Emanuele Giaquinta).
+	- allow `xxx' quoting style for perl selection.
+	- upgrade to libev-3.9 prerelease.
+	- updated compose tables to unicode 5.2.0.
+
+9.06 Sat Nov  8 17:47:18 CET 2008
+	- NOTICE: this release updates terminfo/termcap.
+	- updates libev to 3.48.
+	- the aterm code now frees the as visual and image manager objects
+	  when a window was closed.
+	- do not (wrongly) adjust the virtual line length inside
+	  scr_insdel_chars/ERASE (Miroslav Lichvar).
+	- fix an issue where wide tab characters caused character shifts
+	  when part of them was deleted (tracked down by Miroslav Lichvar).
+	- artificially enlargen the previous character at the end of a line
+	  when trying to output a character that doesn't fit. looks ugly, but
+	  makes copy&paste work.
+	- remove bogus "setuid/setgid security issues" from rxvt.1.pod, they
+	  no longer apply.
+	- the urgency hint is now cleared on both focus in and focus out.
+	- cache urgency hint locally to avoid server rtt on every focus change.
+	- perl 5.10 needs PERL_SYS_INIT3 on hppa.
+	- ignore byte-order marks and do not treat them like combining characters.
+	- fix build issue when CURSOR_BLINK is not defined (Emanuele Giaquinta).
+	- do some µ-optimisations to the character fast path.
+	- use a less cunning, but more robust algorithm to avoid one terminal
+	  monopolising the whole process by outputting a lot of text.
+	- try to work around linux first breaking sched_yield and now breaking
+	  the only known workaround.
+	- new option -icon to set _NET_WM_ICON (based on patch by Frank Schmitt).
+	- initialise the as visual only on demand, instead of unconditionally,
+	  to save memory in the common case of not using visual gimmicks.
+	- try to work around bugs in a few wm's that erroneously resize
+	  client windows on hint property updates by temporarily
+	  disabling size hints.
+	- implement the DECSTR soft reset sequence and use it for tput init,
+	  and make hard RIS and DECSTR both reset more private modes, such
+	  as mouse reporting.
+	- redundantly clear mouse reporting and a few other states in
+	  tput init/tput reset, for older urxvts.
+	- partial/full clear screens did cause flickering and possibly pixel
+	  droppings when urxvt viewed the scrollback buffer.
+	- use current rendition style in DCH sequence.
+	- the 132/80 mode switch no longer forces a screen reset.
+	- add an osc sequence to change the border colour (Emanuele Giaquinta).
+	- new perl extension "overlay-osc", for status displays and the like.
+	- fix some minor cursor drawing issues with overlays by allowing
+	  overlays to modify screen flags (to disable the cursor themselves).
+	- work around programs not restoring rstyle before rmcup
+	  (analysed by Miroslav Lichvar).
+
+9.05 Sun Jun 15 20:09:20 CEST 2008
+	- new option --cd/chdir to set the starting working directory.
+	- tabbed extension now starts in the "correct" working directory.
+	- work around fedora 9 providing isastream but not the relevant
+	  header file for it (report by Tuncer Ayaz).
+	- upgrade libev, fixing a bug in the select backend.
+	  with more than 31 file descriptors on non-linux 64 bit systems.
+	- correctly reset the multibyte state to the initial one
+	  after EILSEQ (patch by Neil Booth). This fixes the
+	  issue of rxvt-unicode not properly displaying text after an illegal
+	  sequence on NetBSD and probably other systems.
+	- more intelligent property handling with -pe tabbed, works around
+	  broken window managers (kwm et al.), saves bandwidth and should
+	  help working window managers as well.
+	- made tabs moveable (based on a patch by Petr Machata).
+	- implement ESC [ 3 K as a more rational alternative to ESC [ 0 K.
+	- support relative paths for RXVT_SOCKET in urxvtd.
+	- the tabbed extension now blindly copies over all (rxvt-) resources
+	  from the toplevel window to the children.
+	- better diagnostic on 0x0 window geometries.
+	- update AnyEvent API to version 3.4 and above.
+	- document the default value of :0 for DISPLAY.
+	- rename perl method XChangeWindowProperty to XChangeProperty.
+
+9.02 Tue Jan 29 11:58:36 CET 2008
+	- the "exg makes everybody happy" release.
+	- fix build with !xft.
+	- always compile in plain style scrollbar (simplifies code and looks great).
+
+9.01 Sat Jan 26 20:49:27 CET 2008
+	- be more aggressive about handling X events, this seems to be required
+	  with newer xlibs (should fix the "screen stays black until event is
+	  received" problem, again :)
+	- add buffered resource to control xft double-buffering.
+
+9.0  Fri Jan 25 19:34:04 CET 2008
+	- fix a crash bug where urxvtd would crash when urxvtc was called
+	  with wrong arguments (I wish debian maintainers in general would
+	  report bugs and their proposed fixes to the original package maintainers
+	  instead of sitting on them for good measure to see if anybody notices).
+	- drawing xft compose characters was causing garbage to be drawn.
+	- correctly clear xft character background in all cases.
+	- implement bracketed paste mode (xterm private mode 2004).
+	- improve documentation on alpha channel handling, make urxvt
+	  work better on servers lacking the RENDER extension when alpha
+	  channels or background images are used.
+	- check for refresh after initialising to avoid staying blank
+	  till the first event arrives. or so.
+	- the FORCE_UNBUFFERED_XFT feature macro works again.
+	- continuously update transparency while moving/resizing now.
+	- OSC 39/49 are deprecated and aliased to OSC 10/11.
+	- cub1 now acts as advertised (and ignores the "wrapped" state).
+	- the 132/80 mode switch now forces a height of 24, too, and
+	  resets the terminal.
+	- scrollbar code cleanups.
+	- stopping children is no longer confused with children exiting.
+	- removed (undocumented) #aarrggbb format.
+	- updated to libev 3.0.
+
+8.9  Mon Dec 24 07:51:40 CET 2007
+	- fix the issue where urxvtd would not immediately close a window
+	  when the command exited but only on the next X event.
+	- changed terminfo file not to use application keypad mode.
+	- fix the issue where making a selection in one urxvtd window
+	  would not clear it visually in another.
+	- fix an issue of urxvt not getting background pixmap updates
+	  and flickering after bg pixmap changes (reported by Mikachu).
+	- fix redraw bug in xterm scrollbar with -sr (reported by Mikachu).
+	- correctly provide dependencies for libev (µikachu).
+	- minor code reorganisations and cleanups.
+	- be more robust in case the urxvt-popup extension cannot be loaded.
+
+8.8  Sat Dec 15 19:40:39 CET 2007
+	- option -C was aliased to all unsupported options, activating
+	  options that shouldn't be compiled in, leading to interesting
+	  effects.
+	- updated libev, working around a bug in linux 2.4, curing the
+	  symptom of urxvt not closing its window on shell exit. also
+	  fixes a problem with urxvt not refreshing.
+	- the text blink callback was called even when no blinking
+	  text was visible.
+	- pre-8.4 slipwheeling behaviour has been reinstated, with
+	  some minor improvements.
+	- streamlined x events processing to only flush once per
+	  display and not once per terminal window.
+	- quite a bit of minor code cleanups and codesize optimisations.
+
+8.7  Sun Nov 25 10:23:49 CET 2007
+	- update libev with an important bugfix that would cause crashes
+	  when closing windows (when using rxvtd, and update is recommended).
+	- do not compile in the block builtin graphics with --disable-frills.
+
+8.6  Fri Nov 23 14:10:57 CET 2007
+	- upgrade libev to disable kqueue on anything but netbsd as it
+	  seems to be broken everywhere else w.r.t. ptys.
+	- allow for spurious event notifications, as at least epoll and
+	  especially solaris ports like to lie about them (symptoms:
+	  urxvt "hangs" until there is some x11 related activity).
+	- -keysym command line options are now subjected to xlib parsing.
+	- add 'xrm' option analogous to Xt one.
+
+8.5a Wed Nov 21 10:16:33 CET 2007
+	- make it compile with --disable-transparency.
+
+8.5  Wed Nov 21 05:19:20 CET 2007
+	- expect major portability issues in this release: please test and report.
+	- converted from the veritable io manager event loop to
+	  the high performance libev (http://software.schmorp.de/pkg/libev).
+	- minor tuning to the perl selection (include single words and more quoting chars).
+	- fix memory leak in pixmap code.
+	- fix a serious bug while setting the XIM destroy callback
+	  on (typical) 64 bit systems.
+	- automove-background functionality re-implemented internally using :root op in pixmap
+	  geometry string. For example: rxvt -pixmap "image.jpg;:root"
+	- do not link rxvtc against every lib on the planet anymore.
+	- parallel builds should work once more.
+
+8.4  Sat Oct 27 14:02:13 CEST 2007
+	- overhaul of the transparency/pixmap code (sasha).
+	- fix possible race between visual bell and poweron.
+	  (reported by Martin von Gagern, gentoo?).
+	- urxvt -e no longer crashes the child.
+	- fixed some minor memleaks on incorrect usage or
+	  missing DISPLAY.
+	- implement xterm 1002/1003 mouse tracking modes (exg).
+	- source code organisational cleanups (exg).
+	- updated io_manager.
+
+8.3  Wed Aug  1 20:21:31 CEST 2007
+	- new option: skipScroll/-ss, enabled by default.
+	- go with the times and expect x11 library files in /usr/lib, not
+	  /usr/X11R6/lib.
+	- initial transparency improvement/afterimage support
+	  patch by Sasha Vasko.
+	- add urgentOnBell resource to set the urgency hint
+	  (patch by Philip Paeps).
+	- do not process focus events caused by grabs
+	  (patch by Mikachu).
+	- add iso14755_52 resource to disable iso14755 5.2 (exg).
+	- add binding for backspace in iso14755 5.1 to remove the last
+	  digit (exg).
+	- better option handling, support more than 30 options (exg).
+	- nuke reconf script, serves no purpose anymore.
+	- fixed and documented matcher/on_user_command processing in matcher
+	  extension (tpope).
+	- compile out of the box on Solaris 10 (exg).
+	- fix MappingNotify events (reported by Stephan Walter).
+	- zero-initialise mwmhints, this seems to solve all sorts of minor
+	  problems.
+
+8.2  Sat Feb 17 21:35:28 CET 2007
+	- fix make depend in src/, reported by exg.
+	- fixed typo in urxvt::GET_CUSTOM, causing the result to be wrong.
+	  (patch by Sergey Vlasov).
+	- unbundled iom perl interface somewhat.
+	- scrollbar-xterm now uses the selected scrollColor instead of fg
+	  (found by Aiviru).
+	- disabled linux kernel bug workaround again: disabling it gives
+	  a 50% speed hit on affected machines, while enabling it gives
+	  a similar speed hit to screen, which is likely the more common
+	  case to work around for :/
+	- urxvt::rend2mask perl function, and utilization of it by matcher
+	  (patch by Moshe Kamensky).
+	- use perl:matcher on a keysym to open most recently displayed URL.
+	- with matcher, when multiple patterns match, last wins, not first.
+	- fix make and make install with srcdir != builddir (exg).
+	- updated bundled libptytty to fix a bug where the tty would be kept
+	  open (see the libptytty ChangeLog for details).
+	- delay setting the IUTF8 flag to after the tty settings have been
+	  set so its value does not get lost (reported and analysed by Andrei
+	  Paskevich).
+	- rip out support for obsolete sgtty.h interface.
+	- rip out support for non-POSIX termios variants.
+	- update libptytty.
+	- update iom.C, make it call ptytty::sanitise_stdfd on init.
+	- when !XFT, change rounding of colours to use a less correct formula to
+	  meet user expectancies (#aaa becomes #a000a000a000 not #9f9f9f9f9f9f).
+	- change the starting offset of the pixmap set with backgroundPixmap
+	  from (50,50) to (0,0) (exg).
+	- fix a typo in button_release, now meta-button2 request the value of
+	  the Clipboard selection as it should (patch by Serge Koksharov).
+	- fix a bug in drawing a cell with a nonspacing char when using an xft
+	  font with inheritPixmap and tintColor (exg).
+
+8.1  Thu Dec  7 22:27:25 CET 2006
+	- ｹﾘｽﾏｽﾌ゚ﾚｾ゙ﾝﾄ - zomg!!1, it's too early!!!
+	- fix the assumption that chars < 256 are single-width. Now
+	  only assume this for codepoints 32 to 126 (reported by Dai.H.).
+	- $term->strwidth
