= Mercurial 3.8 release = == Features == * `hg update` and other commands that can perform update (such as `hg pull -u`) now warn about other topological heads * [[CHg|cHg]] has been added * `hg update` now updates to the tip-most changeset on the same topological branch. Before, it would update to the tip-most changeset, possibly on a different topological head * Hints on how to continue interrupted commands are now printed (e.g. `hg resolve -m` will now tell you to run `hg rebase --continue` or `hg histedit --continue`) * The experimental automv extension has been added. This extension attempts to detect file copes and renames automatically. * The 3rd party hgwatchman extension has been imported as the [[FsMonitorExtension|fsmonitor extension]]. This extension uses filesystem watching to make commands like hg status significantly faster on large repositories. * `hg rebase` now chooses its default destination the same way `hg merge` does * `hg pull -u` now activates a bookmark if the has a bookmark * `hg pull -u` now deactivates a bookmark if the destination doesn't match the existing bookmark * Improved edge styles in graph log. Cset:d7af9b4ae7dd * User template keywords and functions can be defined in `[templatealias]` section. * It's now possible to push the active bookmark using `hg push -B .`. == Improvements == This release includes many improvements, including (but not limited to): * performance of copy detection during rebases has been improved, potentially leading to faster rebase execution * performance of `hg log -f ` has been improved * syntax errors in loaded extensions are now handled better * `hg update` on Windows should now be up to 4x faster * JSON encoding should now be proper UTF-8 for all inputs * Performance of the `-` revset operator has been improved * The blackbox extension now logs more data * "hgext" is now a Python namespace package * revsets accessing changelog data (commit messages, authors, dates) are now 10-15% faster * hg.exe built in MinGW will now link against the proper Python DLL A full overview is available on WhatsNew.
