Zerobyte Release Notes

⚠️ Breaking Changes

Dynamic secret references have been removed. env://... and file://... values are no longer resolved from repository or volume settings. It was replaced by startup-time provisioning instead: define those resources in a provisioning file and let Zerobyte resolve secret references during startup. This feature was removed because it is too difficult to secure properly in an multi-user environment.

Before upgrading, replace any existing env://... or file://... values with the real secrets, or migrate those resources to file provisioning. Otherwise, affected connections may fail after the update. See example documentation

If you didn't use dynamic secret references, nothing changes for you

I have opened a discussion if anyone wants to ask questions or understand in more details why this had to be removed

Improvements

Backup details now include a snapshot order toggle, so you can switch between oldest-first and newest-first views

Bug Fixes

• Snapshot and archive downloads now handle filenames with special characters more reliably
• Rejects include patterns that escape the selected volume root, preventing invalid backup configurations from being accepted
• Snapshot actions such as restore, download, delete, and tag now handle unusual snapshot IDs or refs that begin with - correctly
• Fixed permission handling for temporary credentials files, causing issues on some specific file systems

New Features

• Zerobyte now includes a light theme, with a header toggle
• Backup ETA: running backups now show an estimated time remaining alongside progress details.

Bug Fixes

• Snapshot downloads are more reliable: dumping files from snapshots was fixed to avoid interrupted or incomplete downloads.
• Rclone-backed volumes no longer time out almost immediately because of an incorrect timeout conversion.
• Container timezone handling was fixed for certain timezones missing in the base alpine image
