Mercurial 4.3 (2017-08-07)

Mercurial 4.3 (2017-08-07)#

Mercurial 4.3 release#

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

Security fixes#

CVE-2017-1000115#

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

CVE-2017-1000116#

Mercurial was not sanitizing hostnames passed to ssh, allowing shell injection attacks 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.
