Release notes:

Stability improvements

Reduce disk utilization when catching up by not downloading everything before performing actual work.
Force sync bucket files when performing bucket operation. There was a small chance that buckets would be “lost” during certain events like a hard reboot, causing the instance to be in an unrecoverable state.
Do not try to “fix missing buckets” as this is misleading
Fixed race condition (caused by doing redundant work) when publishing to multiple archives
Fixed http command to ban nodes that was broken in a previous release.
Automated quorum set generator was generating invalid quorum sets when using all 3 quality levels in a single configuration.
Add a way for load generator to mark run as “failed”.
Fix a race condition on Windows that was causing catchup to fail.

Squash SQL schema changes, it’s now not possible to upgrade an instance older than 11.0.0
