bun lint and bun format go native (
c39c718)
Bun adds first-class linting and formatting commands with config support for ESLint/oxlint and Prettier/oxfmt-style workflows. This is a major expansion of the CLI, bringing a large built-in toolchain and new docs/tests to support it.
Yarn Berry lockfiles now migrate to bun.lock (
d1cb7db)
bun install can now convert Yarn 2+ lockfiles instead of rejecting them, preserving pinned versions when Bun can faithfully represent the graph. The migration handles workspaces, patches, aliases, git/tarball/file deps, catalogs, and more; when it can't preserve semantics exactly, it explains why and falls back to resolving from package.json.
bun check closes more gaps with tsc (b92e2f4)
This fixes several correctness issues around unions/intersections, readonly/private/protected property behavior, and large paths configs that previously caused quadratic work. It also tightens a few remaining parity differences with TypeScript in loop/destructuring cases.
bun check improves circular/looped type resolution (772f87f)
A broad refactor adjusts how bun check tracks in-progress resolutions, cached signatures, and loop visibility so it matches tsc on many more programs. The changes target subtle cases around recursive inference and Promise-like then resolution, reducing false errors and disagreement with TypeScript.
DOM constructors now validate subclassing before side effects (
39bbb71)
Web-facing constructors like WebSocket, Worker, and BroadcastChannel now read new.target.prototype before creating underlying resources. That prevents cases where a thrown subclassing check would otherwise leave a socket, subscription, or thread already started.
