I just released i3 v4.15. Release notes follow:

 │ Release notes for i3 v4.15 │

This is i3 v4.15. This version is considered stable. All users of i3 are
strongly encouraged to upgrade.

Aside from a number of fixes and documentation improvements, a number of
commands have been extended to be more complete (e.g. “assign”, “resize”).

 │ Changes in i3 v4.15        │

  • build: AnyEvent::I3 moved to the i3 repository, so that its main consumer,
    the i3 testsuite, can use new features immediately (such as the tick event,
    in this case).
  • docs/hacking-howto: promote “using git / sending patches” and “how to
    build?” sections
  • docs/i3bar-protocol: document that pango markup only works with pango fonts
  • docs/ipc: document focus, nodes, floating_nodes
  • docs/ipc: urgent: complete the list of container types
  • docs/ipc: document how to detect i3’s byte order in memory-safe languages
  • docs/ipc: document the GET_CONFIG request
  • docs/userguide: fix formatting issue
  • docs/userguide: explain why Mod4 is usually preferred as a modifier
  • docs/userguide: use more idiomatic english (full-size, so-called)
  • docs/userguide: switch from removed goto command to focus
  • docs/userguide: mention <criteria> in focus
  • docs/userguide: remove outdated 2013 last-modified date
  • dump-asy: add prerequisite checks
  • dump-asy: fix warnings about empty container names
  • i3-dump-log: enable shmlog on demand
  • i3-sensible-terminal: add “kitty”, “guake”, “tilda”
  • i3-sensible-editor: add “gvim”
  • i3bar: add --release flag for bindsym in bar blocks
  • i3bar: add relative coordinates in JSON for click events
  • ipc: rename COMMAND to RUN_COMMAND for consistency
  • ipc: implement tick event for less flaky tests
  • ipc: add error reply to “focus <window_mode>”
  • ipc: send success response for nop
  • default config: add $mod+r to toggle resize mode
  • default config: use variables for workspace names to avoid repetition
  • introduce “assign <criteria> [→] [workspace] [number] <workspace>”
  • introduce “assign <criteria> [→] output left|right|up|down|primary|<output>”
  • introduce a “focus_wrapping” option (subsumes “force_focus_wrapping”)
  • introduce percentage point resizing for floating containers:
    “resize set <width> [px | ppt] <height> [px | ppt]”
  • introduce “resize set <width> ppt <height> ppt” for tiling windows
  • rename “new_window” and “new_float” to “default_border” and
    “default_floating_border” (the old names keep working)
  • output names (e.g. “DP2”) can now be used as synonyms for monitor names
    (e.g. “Dell UP2414Q”).
  • the “swap” command now works with fullscreen windows
  • raise floating windows to top when they are focused programmatically
  • _NET_ACTIVE_WINDOW: invalidate focus to force SetInputFocus call
  • make focus handling consistent when changing focus between outputs
  • round non-integer Xft.dpi values
  • tiling resize: remove minimum size
