This is a scheduled bugfix release. The hgweb script was fixed to handle index generation for invalid paths. Handling of symlinks was improved for the keyword extension. Several bugfixes were made to subrepositories: removal of read-only Subversion files on Windows was fixed, a missing .hgsub file is now handled as if it was removed, empty directories are pruned when a Subversion subrepository is removed, a Python 2.6 bug was fixed for subrepositories. The MQ extension was fixed to ignore subrepositories. Support for generating x64 native MSI packages was added.
