# `cc-backend` version 1.5.1
Supports job archive version 3 and database version 12.
Supports job archive version 3 and database version 11.
This is a bugfix release of `cc-backend`, the API backend and frontend
implementation of ClusterCockpit.
For release specific notes visit the [ClusterCockpit Documentation](https://clusterockpit.org/docs/release/).
If you are upgrading from v1.5.0 you need to do another DB migration. This
should not take long. For optimal database performance after the migration it is
recommended to apply the new `optimize-db` flag, which runs the sqlite `ANALYZE`
and `VACUUM` commands. Depending on your database size (more then 40GB) the
`VACUUM` may take up to 2h.
## Changes in 1.5.1
### Database
- **New migration (version 12)**: Added covering index for stats queries for significantly improved query performance
- **New migration (version 11)**: Optimized database index count for better performance
- **New migration (version 11)**: Optimized database index count and added covering indexes for stats queries for significantly improved query performance
- **Migration 9 fix**: Removed redundant indices from migration 9 that are superseded by migration 11
- **Optional DB optimization flag**: Added `-optimize-db` CLI flag to run `ANALYZE` on demand; removed automatic ANALYZE on startup
- **Selective stats queries**: Stats queries are now selective, reducing unnecessary computation
