Flux v2.8.3 released on 16-03-2026
Flux v2.8.3 is out now. It fixes a regression in helm-controller that caused templating errors for charts containing literal ‘—‘ sequences (YAML document separators, embedded scripts or CAs in ConfigMaps), so users who saw chart render failures should upgrade.
See the release on GitHub for the full changelog and upgrade guidance; follow the Flux v2.7+ upgrade procedure when moving from v2.6 (upgrade procedure, full changelog: v2.8.2…v2.8.3).
What’s in this release
- Fix for helm-controller templating errors when charts include literal ‘—‘ sequences, restoring correct chart rendering.
- Bundles helm-controller v1.5.3 — see the component changelog for details (helm-controller v1.5.3 changelog).
- Small CLI and toolkit updates: update-branch now shows the target branch name, plus automated toolkit component updates via PRs.
Upgrade notes
- Recommended for all users; follow the Flux v2.7+ upgrade procedure when upgrading from v2.6 (follow the procedure).
- If you need to revert, roll back to the previous release (v2.8.2).
