-# Incompatibilities
-
-Version 0.4 is incompatible with previous versions.
-The default location of the store has changed.
-The directory name of the default store used to be `sledstore`.
-Now it is just `store`. The program attempts to rename
-the store's directory name automatically. E.g. on Linux it tries
-to automatically rename
-`~/.local/share/matrix-commander-rs/sledstore/` to
-`~/.local/share/matrix-commander-rs/store/`.
-If you have used the default store name in the past,
-and automatical renaming is failing for you, then rename the store's
-directory name from
-`sledstore` to `store` manually. Also, some JSON and
-text output is different than in previous version. If you are parsing
-the output you should do careful testing to adapt to the changed
-output.
