+# v0.3.1 (2024-07-16)
+
+* Bumped minimum Go version to 1.21.
+* Added support for authenticated media.
+* Added `/powerlevel` command for managing power levels.
+* Disabled logging by default.
+* Changed default log directory to `~/.local/state/gomuks` on Linux.
+
+# v0.3.0 (2022-11-19)
+
+* Bumped minimum Go version to 1.18.
+* Switched from `/r0` to `/v3` paths everywhere.
+  * The new `v3` paths are implemented since Synapse 1.48, Dendrite 0.6.5,
+    and Conduit 0.4.0. Servers older than these are no longer supported.
+* Added config flags for backspace behavior.
+* Added `/rainbownotice` command to send a rainbow as a `m.notice` message.
+* Added support for editing messages in an external editor.
+* Added arrow key support for navigating results in fuzzy search.
+* Added initial support for configurable keyboard shortcuts
+  (thanks to [@3nprob] in [#328]).
+* Added support for shortcodes *without* tab-completion in `/react`
+  (thanks to [@tleb] in [#354]).
+* Added background color to differentiate `inline code`
+  (thanks to [@n-peugnet] in [#361]).
+* Added tab-completion support for `/toggle` options
+  (thanks to [@n-peugnet] in [#362]).
+* Added initial support for rendering spoilers in messages.
+* Added support for sending spoilers (with `||reason|spoiler||` or `||spoiler||`).
+* Added support for inline links (limited terminal support; requires
+  `/toggle inlineurls`).
+* Added graphical file picker for `/upload` when no path is provided
+  (requires `zenity`).
+* Updated more places to use default/reverse colors instead of white/black to
+  better work on light themed terminals (thanks to [@n-peugnet] in [#401]).
+* Fixed mentions being lost when editing messages.
+* Fixed date change messages showing the wrong date.
+* Fixed some whitespace in HTML being rendered even when it shouldn't.
+* Fixed copying non-text messages with `/copy`.
+* Fixed rendering code blocks with unknown languages
+  (thanks to [@n-peugnet] in [#386]).
+* Fixed newlines not working in code blocks with certain syntax highlightings
+  (thanks to [@n-peugnet] in [#387]).
+* Fixed rendering more than one reaction of the same type in a single message
+  (thanks to [@n-peugnet] in [#391]).
+* Fixed line-wrapped messages getting corrupted when receiving a reaction
+  (thanks to [@n-peugnet] in [#397]).

+  (thanks to [@octeep] in [#270]).

+* Added support for getting custom download directory with `xdg-user-dir`.
+* Added support for updating homeserver URL based on well-known data in
+  `/login` response.
+* Updated some places to use default color instead of white to better work on
+  light themed terminals (thanks to [@zavok] in [#280]).
+* Updated notification library to work on all unix-like systems with `notify-send`.
+    * Notification sounds will now work if either `paplay` or `ogg123` is available.
+    * Based on work by [@negatethis] (in [#298]) and [@begss] (in [#312]).

+A Matrix client written in Go using [mautrix](https://github.com/mautrix/go).
 
-A terminal Matrix client written in Go using [mautrix](https://github.com/tulir/mautrix-go) and [mauview](https://github.com/tulir/mauview).
+This branch contains gomuks web. For legacy gomuks terminal, see the
+[master branch](https://github.com/tulir/gomuks/tree/master). The new
+version will get a terminal frontend in the future. See also:
+<https://github.com/tulir/gomuks/issues/476>.
 
-Basic usage is possible, but expect bugs and missing features.

+## Please note: Template replacements don't work in this file. They are provided with default defines like
+## mentioned underneath.
+## If the keyword is not defined, "wails_tools.nsh" will populate them.
+## If they are defined here, "wails_tools.nsh" will not touch them. This allows you to use this project.nsi manually
+## from outside of Wails for debugging and development of the installer.
+##
+## For development first make a wails nsis build to populate the "wails_tools.nsh":
+## > wails build --target windows/amd64 --nsis
+## Then you can call makensis on this file with specifying the path to your binary:
+## For a AMD64 only installer:
+## > makensis -DARG_WAILS_AMD64_BINARY=..\..\bin\app.exe
+## For a ARM64 only installer:
+## > makensis -DARG_WAILS_ARM64_BINARY=..\..\bin\app.exe
+## For a installer with both architectures:
+## > makensis -DARG_WAILS_AMD64_BINARY=..\..\bin\app-amd64.exe -DARG_WAILS_ARM64_BINARY=..\..\bin\app-arm64.exe
