+===================================================================================
+Release Notes For v1.3.0
+===================================================================================
+
+Version 1.3 is supposed to be fully backwards compatible with 1.2.
+
+For users:
+
+* Behavioural changes
+
+  Dunst respects the timeout with millisecond accuracy now. Notifications with
+  a one second timeout are not shown up to three seconds.
+  Additionally you can specify timeout values in milliseconds, seconds, minutes,
+  hours or days using the ms, s, h, or d suffix in the config value
+  respectively.
+
+  Transient notifications time out ignoring the `idle_threshold` setting and are not
+  saved in history. This can be overridden with a rule containing `set_transient = no`.
+  In the same vein there is the `match_transient` condition to match transient
+  notifications via rules.
+
+  A prefixed tilde (`~/`) in path settings (browser, dmenu, script) is interpreted as the
+  home folder of the user.
+
+* Configuration Options
+
+  `icon_folders` got deprecated and renamed to `icon_path`. `icon_folders` is still
+  supported, but will get removed in future.
+
+  The option `ellipsize` got introduced. It controls where to ellipsize the text of
+  an overlong notification if `word_wrap = no`.
+
+For maintainers:
+
+* Dependencies
+
+  The GTK3+ dependency got removed. Instead of this gdk-pixbuf is required
+  explicitly. This had been a transient dependency before.
+
+  In the Makefile, libxrandr is now specified to require version 1.5 or newer.
+  The dependency on libxrandr >= 1.5 is not new, Dunst 1.2.0 required it too
+  but there was no active check for it.
+
+* Installation process
+
+  The internals of dunst's make installation process have slightly changed. The
+  install routine won't install the service files for DBus and systemd in a hardcoded
+  subdirectory of $PREFIX. It'll now query the `dbus-1` and `systemd` pkg-config
+  packages for those paths and will put it there.
+
+  To overwrite the pkg-config values, you can manually specify another path.
+  Use `SERVICEDIR_(DBUS|SYSTEMD)` vars as parameters to your make calls.
+
+  For all introduced variables, see [the README.md].
+
+* Portability
+
+  GNU-specific functions have been disabled to make dunst portable to nongnu libc's.
+
+For a full list of changes see [CHANGELOG.md].
