+## Known Bugs ❗❗
+
+Version `0.4.4` is a "workaround" release that is branched off of version
+`0.3.7`. Once a new release of `ggez` is released that fixes the known bugs,
+a new version will be released with the fixes. Because this is based on
+`0.3.7` of `mpd_info_screen`, Wayland support may not work. Try using `xwayland`
+with the environment variable `WINIT_UNIX_BACKEND=x11` set. A future release
+using the latest version of `ggez` should work with Wayland.
+
+Currently, the dependency "ggez 0.8.1"
+[fails to render album art](https://github.com/Stephen-Seo/mpd_info_screen/issues/1)
+on my machines using the latest version of this program (`main` branch). A
+version with this fix cannot be published to https://crates.io due to this
+version referring to a git commit as a dependency. Once ggez has released a new
+version with the commit that fixes this bug, this repository will be updated to
+use that version.
