kopia v0.23.0 released on 12-05-2026
kopia v0.23.0 is out now. It improves CLI security by restricting the insecure unauthenticated server to loopback binds and delivers a set of storage-provider and on-disk persistence fixes that reduce data-loss risk.
See the release notes on the Kopia GitHub repository for full details and the complete changelog.
What’s in this release
- Insecure unauthenticated server mode now restricted to loopback binds to tighten CLI security.
- New registration mechanism for storage providers to make provider handling cleaner and more explicit.
- On-disk persistence improvements: FS provider now syncs files and index blob files are synced before close to reduce the chance of lost data.
Upgrade notes
