## Synfig 1.4.3 Release Notes

Synfig Studio 1.4.3 introduces major performance optimizations for Windows users and important bugfixes for all platforms. Please read the details below.

### Optimizations for Windows version

```
- We have removed many bottlenecks in Synfig's code, related with redundant calls of "getenv" function. This resulted in great performance improvement of Windows version ([#2826](https://github.com/synfig/synfig/issues/2826)). This fix also gives slight speed boost for MacOS, while Linux users will not see any significant difference.
- Windows version now shipped with embedded Python version 3.8.10, which results in smaller size of distributive and faster installation ([#67](https://github.com/morevnaproject/morevna-builds/pull/67)).

### Critical fixes
