A new hardened Tor Browser release is available. It can be found in the 6.0a4-hardened distribution directory and on the download page for hardened builds.

This release updates firefox to 38.7.1. Mozilla decided to disable the Graphite library in this release and we are taking the same action: irrespective of the security slider settings the Graphite library won't be used for rendering fonts in Tor Browser 6.0a4-hardened. The Graphite font rendering library was already disabled for users on the security level "High" or "Medium-High".

Note: There is no incremental update from 6.0a3-hardened available due to bug 17858. The internal updater should work, though, doing a complete update.

Here is the complete changelog since 6.0a3-hardened:
