+## Unreleased
+
+Now by default, `tar` files will be written which works better when checking them into
+Git. Those who need the previous behaviour, can use the `xz` feature instead.
+
+### New Features (BREAKING)
+
+ - <csr-id-55382c0aa6f04a3bb689299c613df2a39f261289/> make `xz2` optional to write uncompressed tar files by default.
+   Previously, compression was beneficial due to storage in `git-lfs`.
+   Now, storing (mostly) non-binary files is actually better moving forward.
