Up until version 1.1, Mercurial took a "when it's ready" approach to releases. Starting with version 1.2, we've switched to a consistent calendar-based release schedule. This helps us get bug fixes and new features into our user's hands more quickly, improve our planning process, and keep our development cycles from growing stagnant.

Time-based Release Plan

How we manage releases.

1. Theory

Up until version 1.1, Mercurial took a "when it's ready" approach to releases. Starting with version 1.2, we've switched to a consistent calendar-based release schedule. This helps us get bug fixes and new features into our users' hands more quickly, improve our planning process, and keep our development cycles from growing stagnant.

2. Major releases

Starting with 6.1, Mercurial now follows a 4-month cycle with the following key dates:

3. Code Freeze

Each release cycle ends with a code freeze that starts approximately two weeks before the release date. When the code freeze begins, the following things happen:

  • default branch is merged into stable
  • stable branch receives the @ bookmark to be checked out in new clones

  • one -rc testing release is made, including binary packages
  • only patches suitable for the stable branch are accepted
  • packagers should start producing nightly builds if possible

The point of the freeze is to get everyone to focus on testing and bug fixes for the upcoming release, so please don't distract from that by sending RFC patches or starting feature discussions.

{i} Please be aware that translators need time to synchronize translations before releases so avoid unnecessary string changes in the last few days of the freeze

/!\ All developers should be sure to check out the stable branch after the freeze is declared (no commits on default, also don't merge stable into default)

4. Rules for code freeze and stable branch commits

Because the code freeze is on the stable branch, the rules for each are the same. The following are allowed:

  • bug fixes
  • error message improvements
  • doc fixes
  • template fixes
  • improved translations

Things that don't belong on the stable branch:

  • code cleanups
  • spelling corrections in comments, etc.
  • minor performance fixes
  • test improvements that don't accompany a fix
  • all work related to new features
  • everything else

The guiding rule for stable is to reduce user-visible defects while minimizing risk and churn. If a change has no user impact, it's not appropriate for stable, even if it has no apparent risk.

5. Minor releases

Minor releases will be made by tagging the current state of the stable branch, which is continually kept in a production-ready state, except for possible issues during the early days of the freeze.

Releases will be made in a timely manner for significant behavior regressions, data integrity issues, or security issues.

Barring such issues, minor releases will be made on or about the first of every month that doesn't coincide with a major release.
