### Branches
* `master`: latest stable release.
* `dev`: latest development branch.
* `dev-slice`: experimental branch with a different way of managing mimalloc pages that tends
to use less memory than regular mimalloc with similar performance. Give it a try and please
report any significant performance improvement or degradation.
* `dev`: development branch for mimalloc v1.
* `dev-slice`: development branch for mimalloc v2 with a new algorithm for managing internal mimalloc pages.
### Releases
### Release
* 2021-01-31, `v2.0.0`: beta release 2.0: new algorithm for managing internal mimalloc pages that tends to use reduce memory usage
and fragmentation compared to mimalloc v1 (especially for large workloads). Should otherwise have similar performance
(see [below](#performance)); please report if you observe any significant performance regression.
* 2021-01-31, `v1.7.0`: stable release 1.7: support explicit user provided memory regions, more precise statistics,
improve macOS overriding, initial support for Apple M1, improved DragonFly support, faster memcpy on Windows, various small fixes.
### Older Releases
* 2020-09-24, `v1.6.7`: stable release 1.6: using standard C atomics, passing tsan testing, improved
handling of failing to commit on Windows, add [`mi_process_info`](https://github.com/microsoft/mimalloc/blob/master/include/mimalloc.h#L156) api call.
* 2020-08-06, `v1.6.4`: stable release 1.6: improved error recovery in low-memory situations,
