Bazaar is a simple decentralized revision control system. Decentralized revision control systems give users the ability to branch remote repositories to a local context. Users can commit to local branches without requiring special permission from the branches that they branched from.

Changes:
This release includes new features like Stacked Branches, improved weave merge, and an updated server protocol. Knit format repositories are deprecated, and it is recommended that users upgrade them. Future releases will continue to support reading and writing them, but the authors will not be tuning them for performance as pack repositories have proven to be better at scaling. This is also the first release to bundle TortoiseBzr in the stand-alone Windows installer.
