 ## Versioning & releases
 
-- Use `bun run version:prod` or `bun run version:beta` to bump versions.
-- Beta releases use `manifest-beta.json`.
+- Use `bun run version:prod` or `bun run version:beta` to bump versions — both bump `manifest.json`; `version:beta` just expects `package.json`'s version to carry a `-beta.N` suffix, which is what marks the release a prerelease.
 - Release tags must match `manifest.json` version exactly (no leading `v`).
 - Attach `main.js`, `manifest.json`, `styles.css` to the GitHub release.

 * Inline Dataview fields are now recognized inside blockquotes and callouts — `> up:: [[Note]]` (and `> - up:: [[Note]]`) now creates the `up` edge, matching the behavior already shipped on the 1.12 maintenance line (4.14.3, #724). A trailing link on the same line still stays ordinary prose, per the #731 fix.

+* Retired `manifest-beta.json` and the separate `version-bump-beta.mjs` script. The 4.15.0 changelog noted BRAT reads `manifest-beta.json` from the repo root, which was true of older BRAT versions; as of BRAT v1.1.0 it's ignored entirely — beta installs are resolved by pinning a release tag and reading that release's `manifest.json` directly. `version:beta` now bumps `manifest.json` the same way `version:prod` does; the only thing that still needs to differ going into a beta release is `package.json`'s version carrying a `-beta.N` suffix.
+* `release:beta` no longer pushes to a hardcoded branch — it pushes whatever branch is currently checked out. The hardcoded `main:main` was harmless on `main` but had been copied verbatim onto the `1.12-compat` branch as `master:master`, a branch that doesn't exist, silently breaking the script there.
+* CI now runs on push to `main` and `1.12-compat`, not only on pull requests. A broken TypeScript pin sat on `main` for two months because nothing ever ran CI against the branch directly.
