============================== Qiskit |version| release notes

.. These release notes get converted into Markdown files via the infrastructure at https://github.com/Qiskit/documentation, which then gets deployed to https://quantum.cloud.ibm.com/docs/api/qiskit/release-notes. Changes to these release notes will update those release notes the next time the API docs are generated for this version.

You should set `earliest-version` to:

if on a stable branch, then the earliest tagged release of the minor series.  For

stable/2.1 this would be 2.1.0rc1.  For stable/2.2 this would be 2.2.0b1.  Typically

you should update this as part of making the x.y.0 "final" release (e.g. when tagging

2.2.0 or 2.3.0).
if on main: it doesn't matter all too much; it just affects how many old release notes

are built and tested as part of the release.  It still needs to be a tag reachable on main,

though, which is typically rc1 tags.
