+ │ 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)

+  • 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
