## 0.32.0
**Release date:** 2022-11-17
This prerelease comes with a major refactoring of the controller's Git operations.
The `go-git` implementation now supports all Git servers, including
Azure DevOps, which previously was only supported by `libgit2`.
This version initiates the soft deprecation of the `libgit2` implementation.
The motivation for removing support for `libgit2` being:
- Reliability: over the past months we managed to substantially reduce the
issues users experienced, but there are still crashes happening when the controller
runs over longer periods of time, or when under intense GC pressure.
- Performance: due to the inherit nature of `libgit2` implementation, which
is a C library called via CGO through `git2go`, it will never perform as well as
a pure Go implementations. At scale, memory pressure insues which then triggers
the reliability issues above.
- Lack of Shallow Clone Support.
- Maintainability: supporting two Git implementations is a big task, even more
so when one of them is in a complete different tech stack. Given its nature, to
support `libgit2`, we have to maintain an additional repository. Statically built
`libgit2` libraries need to be cross-compiled for all our supported platforms.
And a lot of "unnecessary" code has to be in place to make building, testing and
fuzzing work seamlessly.
As a result the field `spec.gitImplementation` is ignored and the
reconciliations will use `go-git`. To opt-out from this behaviour, start
the controller with: `--feature-gates=ForceGoGitImplementation=false`.
Users having any issues with `go-git` should report it to the Flux team,
so any issues can be resolved before support for `libgit2` is completely
removed from the codebase.
