v0.15.0 :: Fleet

Breaking Changes

Imagescan, which has had a long life as an experimental feature, is now disabled by default. It can still be explicitly enabled; more information Image Scan on what this change means and how to keep the feature enabled. #4671 by @weyfonk in #4692

This release introduces Helm v4 and, since this version also incorporates Server-Side Apply, drift correction may be affected. To resolve possible issues where drift correction does not work, use force=true. This will be fixed in the next release.

Future Deprecation Notice

Imagescan will be deprecated in a future release.
