Multi Theft Auto: San Andreas v1.0.1 is focused on fixing some high priority client and server crashes, resolving compatibility issues and improving cross-platform compatibility (including support for running on Mac OS X) for the dedicated server, while fixing some various major bugs within the client and resources package.
This release is backwards compatible with our previous release (v1.0). This means that you can use the new v1.0.1 client to connect to v1.0 servers, however we still encourage server owners to upgrade to the latest version due to the number of issues that were fixed in this release.
On a sidenote: this is also the first release that we're doing from our open-source repository at GitHub, so if you'd like to contribute, be sure to fork our repository!
A basic list of changes can be found in the Changelog on our repository, or in the download's description.
