 Notes:
 
 - Versioning policy: SubMiner stays 0-ver. Large or breaking release lines still bump the minor number (`0.x.0`), not `1.0.0`. Example: the next major line after `0.6.5` is `0.7.0`.
+- Supported prerelease channels are `beta` and `rc`, with versions like `0.11.3-beta.1` and `0.11.3-rc.1`.
 - Pass `--date` explicitly when you want the release stamped with the local cut date; otherwise the generator uses the current ISO date, which can roll over to the next UTC day late at night.
 - `changelog:check` now rejects tag/package version mismatches.
+- `changelog:prerelease-notes` also rejects tag/package version mismatches and writes `release/prerelease-notes.md` without mutating tracked changelog files.
 - `changelog:build` generates `CHANGELOG.md` + `release/release-notes.md` and removes the released `changes/*.md` fragments.
 - In the same way, the release workflow now auto-runs `changelog:build` when it detects unreleased `changes/*.md` on a tag-based run, then verifies and publishes.
 - Do not tag while `changes/*.md` fragments still exist.
+- Prerelease tags intentionally keep `changes/*.md` fragments in place so multiple prereleases can reuse the same cumulative pending notes until the final stable cut.
 - If you need to repair a published release body (for example, a prior version’s section was omitted), regenerate notes from `CHANGELOG.md` and re-edit the release with `gh release edit --notes-file`.
+- Prerelease tags are handled by `.github/workflows/prerelease.yml`, which always publishes a GitHub prerelease with all current release platforms and never runs the AUR sync job.
 - Tagged release workflow now also attempts to update `subminer-bin` on the AUR after GitHub Release publication.
 - AUR publish is best-effort: the workflow retries transient SSH clone/push failures, then warns and leaves the GitHub Release green if AUR still fails. Follow up with a manual `git push aur master` from the AUR checkout when needed.
 - Required GitHub Actions secret: `AUR_SSH_PRIVATE_KEY`. Add the matching public key to your AUR account before relying on the automation.
