potiuk opened a new pull request, #65837:
URL: https://github.com/apache/airflow/pull/65837
Codifies the chart's two-branch development model in both the contributor
guide
(``contributing-docs/10_working_with_git.rst``) and the dev doc
(``dev/README_HELM_CHART2_DEV.md``):
* ``main`` — Airflow Helm Chart 2.x: dropped deprecations, restructuring, and
the in-progress extraction of optional features from the core chart into
separate Kustomize overlays.
* ``chart/v1-2x-test`` — 1.2x.x maintenance line.
Adds explicit Helm Chart 2.0 scope items mirrored from the
[Apache Confluence Release
Plan](https://cwiki.apache.org/confluence/display/AIRFLOW/Release+Plan)
(drop Airflow <3.1, Kustomize overlays, drop in-chart DB, Helm 4.0 review,
multi-instance per namespace), with a pointer to the wiki as the source of
truth as the plan keeps evolving.
Adds a "Contributing a bug-fix that should land in 1.2x.x" section that walks
contributors through the three scenarios (bug in both lines vs. 1.2x.x-only
vs. main-only) and documents the existing ``backport-to-chart/v1-2x-test``
label. The generic ``automatic-backport.yml`` workflow already strips the
``backport-to-`` prefix and feeds the rest to ``cherry-picker``, so the label
is already wired end-to-end with no code changes required. Updates the
committer-side instructions to apply the label before merging.
Docs only — no code or workflow changes.
