Self-hosted ZenNotes server 2.51.0 with the pinned browser artifact web-2.51.0-web.hd4bbb4979ae81a3e (built from ZenNotes/zennotes 8ff2cb86, the desktop 2.51.0 release commit).
What changed for self-hosters: the browser app now registers its service worker from bundled code instead of an inline script, which this server's Content Security Policy had been refusing, so the offline shell installs again. The server code itself is unchanged from 2.50.4 apart from the artifact pin and the version.
Verification before publication: prepare-web installed the archive from the manifest URL and verified every file; vet, package tests and the embedded bundle test passed; a standalone run answered health, served the bundle and sw.js under the policy, refused an unauthenticated listing and wrote a note; the five binaries matched SHA256SUMS; an upgrade and rollback rehearsal against 2.50.4 on one vault and config read and wrote notes byte for byte in both directions.
Docker: adibhanna/zennotes:2.51.0, 2.51, and latest are published from this tag by the repository's Docker publisher.
