25.1. Backwards Compatibility Changes

* The infinitepush extension is believed to be unused, and will be deleted at

the end of 2020 unless users contact mercurial-devel@mercurial-scm.org.

* 'hg grep' now searches working copy file contents by default. We recognize

this is a significant change from past behavior, but surveys of large bodies of users indicated nobody used (and almost nobody understood) the previous no-flags behavior of 'hg grep'. The new behavior aligns with the behavior most users expected (including hg's maintainers), which also happens to be the behavior of 'git grep'. Given that the old behavior was confusing to the point of being unusable, we were comfortable changing this behavior.

25.2. API Changes

* 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from

a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a collection of magic strings. As of now, the values are the same, but code should be prepared for these values to change in the future.

* 'mercurial.hg.updatetotally' is now more thorough about checking its

'updatecheck' keyword argument. Previously invalid values would have used
the configured default updatecheck method, but now will raise ValueError.

* 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking

up changectx instances from a bookmark name. Use 'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.

amend: enable support for closing the branch

   * 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.

== Version 0.8.1 - 2006-04-07 ==

Released [http://www.selenic.com/pipermail/mercurial/2006-April/007534.html 2006-04-07].

 * 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` and `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

=== Backwards Compatibility Changes ===

* The infinitepush extension is believed to be unused, and will be deleted at
  the end of 2020 unless users contact mercurial-devel@mercurial-scm.org.

* 'hg grep' now searches working copy file contents by default. We recognize
  this is a significant change from past behavior, but surveys of large bodies
  of users indicated nobody used (and almost nobody understood) the previous
  no-flags behavior of 'hg grep'. The new behavior aligns with the behavior
  most users expected (including hg's maintainers), which also happens to be
  the behavior of 'git grep'. Given that the old behavior was confusing to the
  point of being unusable, we were comfortable changing this behavior.

=== API Changes ===

* 'mercurial.hg.update*' and 'mercurial.merge.update' now expect a value from
  a set of NAMED_CONSTANTS ('merge.UPDATECHECK_*' constants) rather than a
  collection of magic strings. As of now, the values are the same, but code
  should be prepared for these values to change in the future.

* 'mercurial.hg.updatetotally' is now more thorough about checking its
  'updatecheck' keyword argument. Previously invalid values would have used
  the configured default updatecheck method, but now will raise ValueError.

* 'mercurial.bookmarks.bmstore' no longer has a convenience method for looking
  up changectx instances from a bookmark name. Use
  'repo[repo.bookmarks[name]]' intead of 'repo.bookmarks.changectx(name)'.


=== commands ===
 * amend: add option to update to the current user
 * amend: enable support for closing the branch
 * amend: enable support for using the secret phase
 * bookmarks: actual fix for race condition deleting bookmark
 * bookmarks: remove changectx() method from bmstore (API)
 * branchmap: explicitly warm+write all subsets of the branchmap caches
 * import: add debug messages when parsing data from patch header
 * import: read X-Mercurial-Node email header to determine nodeid
 * log: populate keywords if specified in custom -Tjson(...) or -Tcbor(...)
 * merge: replace magic strings with NAMED_CONSTANTS (API)
 * push: support config option to require revs be specified when running push

=== core ===
 * exchange: abort on pushing bookmarks pointing to secret changesets (Bts:issue6159)
 * exchange: avoid unnecessary conversion of bookmark nodes to hex (API)
 * revlog: add a 'sidedata' parameters to addrevision
 * revlog: add a way to control sidedata changes during revlog.clone
 * revlog: add the appropriate flag is sidedata are passed to 'addrevision'

 * revlog: stop using '_processflags' directly
 * revlog: use the new sidedata map return in the sidedata method
 * templatefuncs: account for user's diffopts in diff() (BC)
 * ui: option to preserve the progress bar

 * unshelve: abort on using --keep and --interactive together
