Beside the new features above, we've done many performance improvements, enhancements and bug fixes on the current features. See the [4.3 milestone](https://github.com/abpframework/abp/milestone/49) on GitHub for all changes made on this version.

This version was a big development journey for us; [150+ issues](https://github.com/abpframework/abp/issues?q=is%3Aopen+is%3Aissue+milestone%3A4.3-preview) resolved, [260+ PRs](https://github.com/abpframework/abp/pulls?q=is%3Aopen+is%3Apr+milestone%3A4.3-preview) merged and 1,600+ commits done only in the [main framework repository](https://github.com/abpframework/abp). **Thanks to the ABP Framework team and all the contributors.**

## The Migration Guide

We normally don't make breaking changes in minor versions. However, this version has some small breaking changes, mostly related to Blazor UI WebAssembly & Server separation. **Please check the [migration guide](https://docs.abp.io/en/abp/4.3/Migration-Guides/Abp-4_3) before starting with the version 4.3**.
