+- Fix `Header.marshal` and the checksum and the length (@reynir, #145)
+- Delete a mutable field about the level into the header (@hannesm, #141)
+- **BREAKING**: de-functorize the package (@hannesm, @reynir, @dinosaure, #140, #143, #146)
+
+  These PRs attempt to de-functorize `Tar` so that users can implement I/O
+  themselves, using `Tar`'s own element serialization/deserialization functions
+  to take advantage of read/write methods. This avoids imposing on the user the
+  implementation of a module that is too rigid in his/her case (which could have
+  performance implications).
+
+  `Tar` offers functions for serializing/deserializing tar-specific elements
+  from `string`. It is then up to the user to know how to obtain or write these
+  `strings`.
+
+  To this, these PRs add "logics" (see `'a Tar.t`) requiring read and/or write
+  implementations and describing how to extract all entries from a tar file or
+  how to write a tar file according to a "dispenser" (like `Seq.to_dispenser`)
+  of entries.
+
+  These logics do not depend on a particular "scheduler", and these PRs propose
+  a derivation of these logics with `tar-unix`, `tar-eio` and `tar-mirage`.
+  These latter derivations mean that the API for these packages has only been
+  extended, and there are no breaking changes as such.
+
+  These logics also make it easy to offer a compression/decompression layer with
+  `decompress`, so you can easily manipulate and/or create a .tar.gz file.
