This is the third bug-fix release of the 2.3.x release cycle! 🎉

This release was triggered by a segfault caused by a memory corruption in the new lufs C code that was introduced with release 2.3.2. If you are using this code and this release, please consider upgrading.

Otherwise, the release includes minor fixes. It should be suitable for production but can be updated at your earliest convenience.

This release is also the first one to include builds for both versions of OCaml: 4.14.x and 5.x. As of now, the memory usage with Ocaml 5 is still significantly higher and not suitable for production in our opinion. However, we will need to make the switch one day or another so we decided to start providing both build to make sure that we stay compatible with the latest ocaml 5 code and can continuously test and improve memory optimization with this version.
