This fixes some issues with Google Chrome that were introduced in 5.0.0. See the draft 5.0.1 release notes for full details.
Please follow these instructions if you want to join the beta testing program. Bear in mind that the chance of encountering bugs in a beta release is higher than in a regular release – please ensure your data is backed up before updating.
As a beta tester, you can help us by providing feedback on stability and hardware support, and reporting software regressions (things that used to work in previous releases that stopped working on this new release).
