LTS Release Process and Support

This page shows the steps on creating an LTS (Long Term Support) release and supporting older LTS versions.

Quick rundown of what LTS entails:

• An LTS release is a feature release tagged as LTS
• An LTS release occurs every 12 months
• An LTS version is supported for at least 18 months before End of Life (EoL)
• At maximum two LTS versions to support concurrently

For a more in-depth overview regarding our LTS approach, check out RFC8 - ISIS Long Term Support.

Instructions to Support Older LTS Version

**Note: Automation of Steps 1 - 3 is TBD. The PR in Step 3 will be manually reviewed and approved before merge.

Step 1: Check the PRs for Labels

• Any bugfix PR that addressed an issue with the bug label should have a bug label as well.
• Manually update PRs with the bug label in preparation for the next step.

Step 2: Cherry-pick the PRs

• Pick and choose the bugfix PRs that will be brought down into the LTS version.

Step 3: Create PR

• Create a PR and manually make the selected bugfixes by hand.
• Be sure to reference the bugfix PRs in the body of this PR.
• Merge the PR into the LTS version of interest.

Step 4: Increment LTS Patch Version

• Increment the patch version of the LTS build.
• Release the newly versioned build via Anaconda.
