== Mercurial 4.1.3 (2017-4-18) ==
This is an out of cycle release to address a security issue:

 * `hg serve --stdio` could be tricked into granting authorized users access to the Python debugger. Thanks to Jonathan Claudius of Mozilla for reporting this issue


== Mercurial 4.1.2 (2017-4-3) ==
This is a regularly-scheduled bugfix release.

 * Mercurial should work inside IIS on Windows again. (Bts:issue5493)
 * zstd support now refuses to work on old bundle formats. (Bts:issue5506)
 * Merges involving subrepositories no longer crash in some cases. (Bts:issue5505)
 * Checking for new heads during push is [[https://www.mercurial-scm.org/repo/hg/rev/ed5b25874d998ababb181a939dd37a16ea644435|no longer]] accidentally quadratic

== Mercurial 4.1.1 (2017-3-2) ==
This is a regularly-scheduled bugfix release.

 * Several incorrect mailing list addresses have been corrected.
 * Various error cases have been corrected during push and pull.
 * Minor issues that happened when Mercurial spawned worker processes have been fixed.

== Mercurial 4.1 (2017-2-1) ==
An [[Release4.1|overview of new features]] available. This is a regularly-scheduled quarterly feature release.		 == Mercurial 4.9 (2019-02-01) ==

An [[Release4.9|overview of new features]] available. This is a regularly-scheduled quarterly feature release that also contains security fixes.

=== security ===

It was possible to use symlinks and subrepositories to defeat Mercurial's path-checking logic and write files outside a repository. This has been fixed. Users on older versions can either disable subrepositories with {{{[subrepos] allowed=false}}} in their configuration or by ensuring any cloned repositories don't contain malicious symlinks.

(3.8.1 was released immediately after 3.8 to fix a release oversight.)

Regularly scheduled feature release. This release contains a low-priority security fix for:

CVE-2016-3105 Mercurial: arbitrary code execution when converting Git repos

 . Mercurial prior to 3.8 allowed arbitrary code execution when using the convert extension on Git repos with hostile names. This could affect automated code conversion services that allow arbitrary repository names. This is a further side-effect of Git CVE-2015-7545. Reported and fixed by Blake Burkhart.

1. Mercurial 4.9 (2019-02-01)

An overview of new features available. This is a regularly-scheduled quarterly feature release that also contains security fixes.

1.1. security

It was possible to use symlinks and subrepositories to defeat Mercurial's path-checking logic and write files outside a repository. This has been fixed. Users on older versions can either disable subrepositories with [subrepos] allowed=false in their configuration or by ensuring any cloned repositories don't contain malicious symlinks.

1.2. commands

  • archive: use manifest.matches() to simplify and speed up matching
  • branch: allow changing branch of merge commits with --rev

  • branches: add -r option to show branch name(s) of a given rev (issue5948)

  • graft: abort if --date/user specified with --currentdate/currentuser (BC)
  • graft: introduce --base option for using custom base revision while merging
  • help: add internals.extensions topic
  • help: show advanced, experimental and deprecated extensions with --verbose

  • log: fix line wrap on diffstat with -G/--graph (issue5800)

  • merge: make local file storage in the .hg/merge directory extensible

  • pull: fix inconsistent view of bookmarks during pull (issue4700)

  • push: add --publish flag to change phase of pushed changesets
  • push: config option to control behavior when pushing to a publishing server

  • resolve: fix mark-check when a file was deleted on one side (issue6020)

  • tags: cache 'repo.changelog' access when checking tags nodes
  • update: fix edge-case with update.atomic-file and read-only files

1.3. core

  • revlog: always enable generaldelta on version 2 revlogs

  • revlog: make sure we never use sparserevlog without general delta (issue6056)
