+
+This is i3 v4.12. This version is considered stable. All users of i3 are
+strongly encouraged to upgrade.
+
+If cairo ≥ 1.14.4 is available, i3 and i3bar will use cairo for rendering
+(instead of raw X11 drawing primitives). While this is currently optional,
+having cairo ≥ 1.14.4 will be a hard requirement in future release.
+
+This release contains a good number of detail improvements and fixes.
+
+ ┌────────────────────────────┐
+ │ Changes in i3 v4.12        │
+ └────────────────────────────┘
+
+  • use https instead of git/http, update contact information, add GPG key
+  • docs/hacking-howto: fix old cfgparse.y reference to config_parser.c
+  • docs/ipc: added link to i3ipcpp (C++ library)
+  • docs/userguide: clarify no_focus documentation
+  • docs/userguide: add documentation for binding modes

+  • man/i3-nagbar: fix example invocation
+  • man/i3: add “floating window” to terminology
+  • i3-sensible-*: quote variables correctly
+  • i3-sensible-editor: add neovim
+  • i3-sensible-terminal: add termit, st
+  • i3bar: use cairo for all drawing operations
+  • i3bar: support per-statusblock border and background colors
+  • i3bar: support different bar background colors depending on whether the bar
+    is on the focused output or not
+  • i3bar: multiple tray_output directives on the same bar are now supported
+  • i3bar: support disabling the modifier by specifying “modifier none”
+  • use cairo for all drawing operations
+  • fix a number of memory leaks, thanks to AddressSanitizer
+  • no_focus is now suppressed for the first window of a workspace
+  • “workspace next/prev” now looks for numbered workspaces after reaching the
+    last workspace (it used to incorrectly only look at named workspaces)
+  • multiple marks can now be set on a single window (but a mark can still only
+    be present on one window at a time)
+  • the “unmark” command now supports criteria
+  • the “con_id” criterion now supports the special value __focused__
+  • the “workspace” command now supports the --no-auto-back-and-forth parameter
+  • the “move window to workspace” command now supports the
+    --no-auto-back-and-forth parameter
+  • the “resize grow|shrink width|height” command now works for a nested split
+    in the same direction
+  • support _NET_WM_USER_TIME’s special 0 value, indicating that a window
+    should not be focused
+  • use 32-bit visual by default if available. This reduces graphical glitches
+    when using transparency (which is still not officially supported)
+  • the “move position center” command now supports criteria
+  • specifying invalid match criteria now results in an error instead of
+    blindly applying the operation to the currently focused window
+  • allow mouse bindings to run on the root window
+  • support matching _NET_WM_WINDOW_TYPE_NOTIFICATION in criteria
+  • all criteria are now matched, even when con_id or con_mark are given (used
+    to be a special case)
+  • allow the “id” criterion to be specified in any base recognized by
+    strtol(), not only base 10
+  • non-true color displays are now supported again (e.g. the Raspberry Pi)
+  • the “split” command now has a “toggle” option
+  • the additional color class “decoration_border” was added
+  • title_format is now stored on containers instead of windows, allowing the
+    use of title_format on split containers
+  • On OpenBSD, i3 now uses pledge(2)
+  • support _NET_WM_DESKTOP (for pager applications like gnome-panel)
+  • floating workspaces are no longer available (they were not supported for a
+    while now)
+  • floating windows now carry the I3_FLOATING_WINDOW atom so that tools like
+    compositors can be configured to match on floating windows
+

+  • i3bar: display short text only on the monitor(s) on which it is necessary
+  • i3bar: explicitly set cursor using libxcb-cursor if available
+  • i3bar: fix XEMBED messages
+  • i3-nagbar: explicitly set cursor using libxcb-cursor if available
+  • duplicated keybindings are now also detected when one uses bindcode but the

+  • keymap fallback for servers without XKB (e.g. TightVNC) has been added
+  • using pango markup in mode names is now optional, fixing a regression in i3
+    v4.11 where modes which contained characters such as “<” would break.
+  • moving windows to a workspace by specifying a mark now works
+  • the root output is now used when any RandR request fails (for x2go)
+  • assignments are now marked as run before executing them, preventing endless
+    loops/crashes when assignments cause another assignment evaluation
+  • splitting/floating a dock container no longer crashes i3
+  • correctly compare modifier mask when identifying keybindings (fixes
+    bindings which use --release)
+  • no longer fail config validation when there is no newline at the end of
+    the config file
+  • scrollwheel buttons are now only grabbed when necessary, allowing the use
+    of “bindsym button*” or scrolling in windows without focusing them (in case
+    no “bindsym button*” is present)
+  • parse con_id in base 16 (affected FreeBSD only)
+  • fix crash when opening a large number of windows
+  • reject empty swallow definitions to avoid crashes
+  • don’t remove SubstructureRedirect event mask temporarily (fixes i3bar
+    stopping after system suspend)
+  • move urgent flag before killing the parent to avoid a crash
+  • correctly validate “kill” command to avoid crashing when “kill” is invoked
+    on workspace containers
+  • actually accept the documented “workspace” token as an alternative to “→”
+    in assign statements
+  • remove _NET_WM_STATE on withdrawn windows to comply with the spec
