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

Version 0.9 - 2006-05-10

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.

Version 0.8.1 - 2006-04-07
