Summary
workerd v1.20260901.1 implements FileSystemWritableFileStream in TypeScript and adds encoding-stream and compression-stream suites with migrated tests. It also catches leaked SQLite handles during initialisation failure.
Why it matters
The additions bring more browser-compatible streaming primitives to server-side JavaScript and reduce runtime resource-leak risk in edge applications.
