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.

http://www.selenic.com/pipermail/mercurial/2006-July/009510.html
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.
Sort PLIST.
Changes:
- new extensions:
mq (manage a queue of patches, like quilt only better)
email (send changes as series of email patches)
- new command: merge (replaces "update -m")
- improved commands: log (--limit option added), pull/push ("-r" works
on specific revisions), revert (rewritten, much better)
- comprehensive hook support
- output templating added, supporting e.g. GNU changelog style
- Windows, Mac OS X: prebuilt binary packages, better support
- many reliability, performance, and memory usage improvements
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
changes:
faster status, diff, and commit
reduced memory usage for push and pull
improved extension API
new bisect, gpg, hgk, and win32text extensions
short URLs, binary file handling, and optional gitweb skin for hgweb
numerous new command options including log --keyword and pull --rev
improved hooks and file filtering
