kopia v0.23.0 released on 12-05-2026

kopia v0.23.0 is out now. Users get safer defaults and more resilient storage and snapshot behaviour.
See the full release notes on the project’s GitHub release page for detailed changes and installation instructions.
What’s in this release
- New restriction that limits insecure, unauthenticated server bindings to loopback addresses to reduce accidental exposure.
- Registration mechanism for storage providers, plus warnings for extra providers and robustness improvements in storage operations.
- Reliability fixes including explicit file syncs in the FS provider, syncing index blob files before close, and limiting PutBlobInPath retries to two attempts.
Upgrade notes
- Removal of LZ4 support — if you rely on LZ4-compressed repositories, plan to migrate away or remain on a prior release; consult the GitHub release notes for migration advice.
- Storage behaviour changes (for example the two-attempt limit for PutBlobInPath) may affect retries on flaky networks; test upgrades in a safe environment before rolling out widely.
