Mercurial 4.8 release

This page consists of 4.8 release which is work in progress.

1. New Features

• Command templates (aka formatter templates) are stabilized. See hg help <command> -v for details.

• New config option commands.resolve.mark-check to warn or abort on resolve --mark when files still have conflict markers

• New config option commands.resolve.confirm to confirm before performing action when no filename is passed.

2. New Experimental Features

• New absorb extension to make working changes "absorbed" into relevant changesets.
• New fastannotate extension to greatly speed up "annotate" with precomputed cache.
• The phabricator extension gets into hgext.

3. Other Notable Features

• Rebaes gets new --stop flag to stop interrupted rebase without discarding the ongoing changes.

• Several performance optimizations on fileset query.

• Sort out command help by categories.
• Improvements to zsh completions:
  • Completing files, shelve and unshelve commands
  • Completing merge tools
  • Completing added and removed (in addition to changed) files to commit and diff commands
  • Numerous updates to flags and descriptions
  • Fixes for minor issues and a couple of performance improvements

4. Bug Fixes

5. Backwards Compatibility Changes

• narrow extension has gone under big backward compatibility changes like introducing new server capabilities, moving narrowspec file to .hg/store/ etc. It's is highly recommened to update both client and server side narrow extension. <More details to be added>

• Emails from the patchbomb extension will always be printed as though they are iso-8859-1 if they're not valid us-ascii. Previously, previewed emails were always claimed to be us-ascii and might contain invalid byte sequences.
• 'hg debugdata' no longer accepts the path to a revlog file.
• Bulk-renaming of the formatter template keywords:
  • "{abspath}" and "{file}" to "{path}". Any "{path}" is a repository-absolute path. Use "{path|relpath}" to convert it to a filesystem path.
  • "{copy}" in status command to "{source}".
  • "{oldhashes}" and "{newhashes}" in journal template to "{oldnodes}" and "{newnodes}" respectively.
  • "{line_number}" to "{lineno}".
  • "{status}" of resolve command to "{mergestatus}".

• A repository will no longer use shared storage if it has a ".hg/sharedpath" file but no entry in ".hg/requires" saying it is shared.
  This change should not have any end-user impact, as all shared repos should have a ".hg/requires" file indicating this.
