The stable Tor Browser Bundles have been updated to fix a crash bug that existed in the previous version. If you were experiencing problems, please update and let us know if you have any further problems.

All alpha bundles have also been updated to Tor 0.2.3.23-rc. We've downgraded the Firefox version in the alpha Tor Browser Bundles to 10.0.9esr and will continue to keep the same version of Firefox in both bundles for the foreseeable future. In addition to that, the Linux and OS X versions have automatic port selection re-enabled, so those of you who were experiencing trouble running a concurrent system Tor on those systems should no longer have any issues.

All users who were using Tor 0.2.3.22-rc are strongly encouraged to upgrade.
