## [Unreleased]

## [1.4.0-beta.2] — 2026-08-20

> **Upgrading: regenerate your bindings, and commit `.bindgen-manifest.json` alongside them.** #190
> introduces a permanent public-name registry — the manifest is now the source of truth that keeps your
> generated type names stable across future bindgen upgrades, so check it in next to the generated code
> and regenerate through it. Two name changes land in this beta and only at the affected type sites, with
> no runtime change:
>
> 1. **Large named `@unboxed` unions follow their upstream alias** (#190). A named union with more than
> four runtime members now emits its source name (`StatusCode` → `statusCode`) instead of enumerating
> every member (hono's `v100OrV101Or…OrV511OrV1`). The previous structural name stays as a transparent
> compatibility alias, so existing call sites keep compiling.
> 2. **Bloated anonymous `@unboxed` union names are capped** (#200). An anonymous union mixing dozens of
> string literals (csstype `Property.*`, surfaced by blend `0.0.38-beta.1`) no longer produces a name up
> to 2,453 chars; past a length cap it degrades to a readable prefix + shape hash. Cosmetic only — the
> emitted `@unboxed` type body is unchanged.
>
> This beta also **unblocks generation on the newest blend** (`0.0.38-beta.1`): a public-identity collision
> that previously aborted the whole run with zero output now degrades to a stable manifest id and a warning
> (#190 follow-up). If you pin blend, you can move to `0.0.38-beta.1` after regenerating.

### Fixed

- **Anonymous large `@unboxed` union names no longer bloat to 2,000+ chars** (#200) — a union that mixes
