+# InstructLab Eval Release Strategy
+
+This document discusses the release strategy and processes for the
+`instructlab-eval` Python package built from the
+<https://github.com/instructlab/eval> git repository.
+
+## Versioning Scheme
+
+Releases use a `X.Y.Z` numbering scheme.
+
+X-stream release are for major releases. At this stage in the project a major release has not been cut and we expect each release to be a new Y-stream.
+
+Z-stream releases are meant for critical bug and documentation fixes. Z-stream releases are cut as maintainers see fit.
+
+## Schedule
+
+The project currently operates on an ad-hoc release schedule based on the discretion of the maintainers team.
+
+The cadence for major releases starting from 1.0 onward will be determined as the project matures.
+
+A schedule will be updated in a markdown file on the <https://github.com/instructlab/eval> GitHub repository.
+
+## Release Tracking
+
+Currently there is no formal process of release tracking. GitHub Issues are used for tracking individual work items.
+
+In the future, the project may use Milestones or Project Boards for more formal release planning. At that time this document will be updated.
+
+## Git Branches and Tags
+
+Every `X.Y` release stream gets a new branch.
+
+Each release, `X.Y.Z`, exists as a tag named `vX.Y.Z`.
+
+## Release Branch Maintenance
+
+Maintenance efforts are only on the most recent Y-stream.
+Critical bug fixes are backported to the most recent release branch.
+
+## Release Mechanics
+
+Release mechanics are done by a Release Manager identified for that release.
+The Release Manager is a member of the Eval Maintainers team that has agreed to take on these responsibilities.
+The Release Manager can change on a per-release basis.
+
+The following are the steps for how Y-stream and Z-stream releases gets cut.
+
+### Y-Stream
+
+1. Determine a commit on the main branch that will serve as the basis for the next release - most of the time this should be the latest commit.
+1. Create a new release branch in the format `release-vX.Y` off of the determined commit (will match `main` if the latest commit is chosen).
+1. Create a new release on GitHub targeting the release branch and using the latest Y-Stream tag as the previous release (e.g. `0.15.1` precedes `0.16.0`).
+1. Announce release via the following:
+    - The `#eval` channel on Slack
+    - The `dev` mailing list
+
+### Z-Stream
+
+1. Backport all relevant commits from `main` to the `release-vX.Y` branch.
+1. Create a new release on GitHub targeting the release branch and using the previous Z-Stream tag as the previous release (e.g. `0.15.0` precedes `0.15.1`).
+1. Announce release via the following:
+    - The `#eval` channel on Slack
+    - The `dev` mailing list
+
+## Release Notes
+
+The project maintains a single `CHANGELOG.md` file that documents all releases. To ensure our users
+are well-informed about new features, improvements, and breaking changes, we maintain a
+`CHANGELOG.md` file. This file serves as a centralized place to document changes that will be
+included in the next (X) or (Y) release. Given that the project is in its early stages, we are
+currently focused on documenting changes for the next (Y) release.
+
+### Editing Release Notes
+
+When submitting a Pull Request (PR) that introduces notable features or breaking changes, committers
+need to update the `CHANGELOG.md` file. Clearly describe the changes, their impact, and
+any actions users might need to take. We want clear, concise, and user-friendly notes.
+
+### Branching for a New Release
+
+Each time we prepare for a new (X) or (Y) release, we branch out from the main codebase.
+As part of this branching process, the contents of `CHANGELOG.md` are reviewed and
+finalized.
