Release Notes

Features and bugfixes in our latest releases. Please see the Download page for links to source and binaries.

Note that Mercurial follows a time-based release plan with major releases every three months and minor (bugfix) releases on the first of every month (see TimeBasedReleasePlan).

Be sure to read the upgrade notes when upgrading.

(See the archive for older versions)

1. Mercurial 4.3.3 (2017-10-01)

• Prevent crashes when clearing progress bar. (issue5684)

• rebase: move bookmarks with --keep (issue5682)

2. Mercurial 4.3.2 (2017-09-18)

• restore compatibility with older versions of Python 2.7 by not using a bytearray with struct.unpack_from()
• restore mingw compatibility for setup.py
• hgwebdir: read 'web.template' untrusted (plugs potential security issue)

• repair: preserve phase when not using generaldelta (issue5678)

• ssh: fix flakey ssh errors on BSD systems

• restore error handling behavior around certain I/O errors; the regressed behavior could result in transactions not being properly rolled back if stdio handles encountered errors (issue5658)

• templatekw: choose {latesttag} by len(changes), not date (issue5659)

• record: fix revert -i for lines without newline (issue5651)

• mq: create non-lossy patches, also with custom global diff configuration

3. Mercurial 4.3 / 4.3.1 (2017-08-10)

(4.3.1 was released immediately after 4.3 to fix a release oversight.)

An overview of new features available. This is a regularly-scheduled quarterly feature release.

3.1. Notable changes

• experimental amend extension providing the amend command
• experimental sparse extension
• Support for Python 2.6 has been dropped.
• Bundles created by the strip extension now store phase information. It will be restored when unbundling.
• The strip extension now removes relevant obsmarkers. If a backup requested (the default), the obsmarkers are stored in the backup bundle and will be restored when unbundling.

• hg show work (from the experimental show extension) now displays more info

• hg show stack is a new view for the current, in-progress changeset and others around it

• Mitigation for two security vulnerabilities

3.2. CVE-2017-1000115

Mercurial's symlink auditing was incomplete prior to 4.3, and could be abused to write to files outside the repository.

3.3. CVE-2017-1000116

Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks on clients by specifying a hostname starting with -oProxyCommand. This is also present in Git (CVE-2017-1000117) and Subversion (CVE-2017-9800), so please patch those tools as well if you have them installed.

4. Mercurial 4.2.3 (2017-08-10)

This was an out-of-cycle backport of security fixes from 4.3 for users stuck on Python 2.6.

5. Mercurial 4.2.2 (2017-07-05)

This is a regularly-scheduled bugfix release.

• largefiles: avoid a crash when archiving a subrepo with largefiles disabled
• rebase: also test abort from pretxnclose error

• rebase: backed out changes 2519994d25ca and cf8ad0e6c0e4 (issue5610)

• rebase: reinforce testing around precommit hook interrupting a rebase

6. Mercurial 4.2.1 (2017-6-4)

This is a regularly-scheduled bugfix release.

• hg graft now works when grafting across merges that were problematic before (b4e1e30528c7).

• A race condition in hg status was partially fixed (issue5584).

• The message about deprecated SHA-1 hashes in the [hostfingerprints] config section now references the correct syntax for replacing them with SHA-256 hashes (issue5559).

7. Mercurial 4.2 (2017-5-2)

An overview of new features available. This is a regularly-scheduled quarterly feature release.

7.1. Notable changes

• Pager support has been moved into core and is now enabled by default. This is now controlled with the ui.paginate setting.
  • Note that in 4.2-rc, the ui.paginate option was named pager.enable. The old name has been dropped in the final release. If you had turned pagination off using pager.enable=False, please update your config.
• Color support has also been moved into core and is now enabled by default (the ui.color setting now defaults to 'auto').

• The new experimental 'show' extension provides a way to view various information about your repository in an ergonomic way. It is deliberately designed for human consumption and not for scripting, so it doesn't carry the same backward compatibility guarantees as other commands. See 'hg help -e show' for more information.

• Mercurial now requires setuptools on Windows.
