Pierre-Sassoulas · 2026-07-14T09:13:16Z

Add 3.15 trove classifier (3.14 already present)
Add 3.14 and 3.15 to tox envlist
Add 3.14 and 3.15 to unit, integration and e2e CI matrices
Enable allow-prereleases on setup-python so 3.15 pre-releases install
Mark 3.15 experimental (continue-on-error) since it is not yet released, so its failures do not block PRs

Add 3.15 trove classifier (3.14 already present)
Add 3.14 and 3.15 to tox envlist
Add 3.14 and 3.15 to unit, integration and e2e CI matrices
Enable allow-prereleases on setup-python so 3.15 pre-releases install
Mark 3.15 experimental (continue-on-error) since it is not yet released, so its failures do not block PRs
