Flux v2.8.3 released on 16-03-2026
Flux v2.8.3 is out now. It addresses a regression in helm-controller that caused templating errors for charts containing literal ‘—‘ sequences (YAML document separators, embedded scripts, or certificate blocks), so users who deploy such charts should upgrade.
See the full changelog on GitHub (compare v2.8.2…v2.8.3) for details, and consult the helm-controller v1.5.3 changelog for component-specific fixes.
What’s in this release
- Fix in helm-controller: resolves templating errors for charts that include literal ‘—‘ sequences (YAML separators, embedded scripts, CAs inside ConfigMaps).
- helm-controller component updated to v1.5.3; consult the component changelog for details.
- Minor CLI and toolkit updates: add target branch name to the “update branch” behaviour and update toolkit components (PRs by fluxcdbot).
