Version 0.9.1 - 2006-07-24

These are the major changes between Mercurial 0.9 and 0.9.1:

• New features:

  • You can now configure your hgweb server to let remote users push changes over http.

  • You can now import a patch in a mail message by saving the mail message, and importing it. This works for patches sent either inline or as attachments.

  • The diff command now accepts -rA:B syntax as a synonym for -r A -r B, and adds -b and -B options.

• New contributions and extensions:

  • The acl extension lets you lock down parts of a repository against incoming changes

  • The extdiff extension lets you run your favourite graphical change viewer

  • Comprehensive integration with the vim editor

  • A restricted shell for ssh-hosted repositories

  • An importer for darcs repositories

• New hooks added:

  • preupdate is run before an update or merge in the working directory.

  • update is run after an update or merge in the working directory.

• Behaviour changes:

  • NOTE: Mercurial as installed by the Windows binary installer no longer performs automatic line-ending conversion for Unix/Linux compatibility. To re-enable this feature, edit your mercurial.ini file after you upgrade.

  • The Windows binary installer now automatically adds hg to your %PATH%.

  • The backout command now runs an editor by default, to let you modify the commit message for a backed-out changeset.

  • An earlier problem with parsing of tags [http://www.selenic.com/repo/hg?cs=dbdce3b99988 has been fixed]. This makes tag parsing slower but more reliable.

• Memory usage and performance improvements:

  • The remove command has been rewritten to be hundreds of times faster in large repositories.

  • It is now possible to clone a repository very quickly over a LAN, if the server is configured to allow it. See the new server section in the hgrc documentation.

• Other changes of note:

  • Mercurial will now print help for an extension if you type hg help EXT_NAME.

  • The usual array of bug fixes and documentation improvements.

  • The integrated web server is now more [http://www.python.org/dev/peps/pep-0333/ WSGI]-compliant.

  • Work has begun to solidify Mercurial's API for use by third-party packages.

Version 0.9 - 2006-05-10

[http://www.selenic.com/pipermail/mercurial/2006-May/008093.html Release announcement.]

These are the 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.
