Version 0.9 of the Mercurial SCM is now available at: http://selenic.com/mercurial/release/mercurial-0.9.tar.gz More information available at: http://selenic.com/mercurial/ Mercurial is a fast, easy to use, lightweight Source Control Management system designed for efficient handling of very large distributed projects, while also excelling for small projects. It is written in Python. Mercurial runs on all popular platforms. It is used by such well-known projects as Xen, OpenSolaris, MoinMoin, and microformats. Many thanks to the numerous developers, testers, and users who contributed to this release. Enjoy! Major changes between Mercurial 0.8.1 and 0.9: - The repository file format has been improved. - This has resulted in an average 40% reduction in disk space usage. - The new format (called RevlogNG) is now the default. - Mercurial works perfectly with both the old and new repository file formats. It can transfer changes transparently between repositories of either format. - To use the new repository format, simply use `hg clone --pull` to clone an existing repository. - Note: Versions 0.8.1 and earlier of Mercurial cannot read RevlogNG repositories directly, but they can `clone`, `pull` from, and `push` to servers that are serving RevlogNG repositories. - Memory usage has been improved by over 50% for many common operations. - Substantial performance improvements on large repositories. - New commands: - 'archive' - generate a directory tree snapshot, tarball, or zip file of a revision - Deprecated commands: - 'addremove' - replaced by 'add' and 'remove --after' - 'forget' - replaced by 'revert' - 'undo' - replaced by 'rollback' - New extensions: - Bugzilla integration hook - Email notification hook - Nested repositories are now supported. Mercurial will not recurse into a subdirectory that contains a '.hg' directory. It is treated as a separate repository. - The standalone web server, 'hg serve', is now threaded, so it can talk to multiple clients at a time. - The web server can now display a "message of the day". - Support added for hooks written in Python. - Many improvements and clarifications to built-in help.
