8.1.0 2026-11-05

Improvements:

• Re-add support for Python 3.12 and 3.13, as they are still used by a lot of setups (e.g. Ubuntu 24.04 LTS and Debian 13). MapProxy now requires Python 3.12 or higher

Maintenance:

• Update GitHub Actions and test dependencies

• Cleaner coverage reports in CI

8.0.1 2026-11-03

Maintenance:

• Use Renovate instead of Dependabot and the docker-update workflow for dependency updates

• Pin GitHub Actions, CI service images and Docker base images to digests

• Docker images of a release are now built from the release tag, manual rebuilds only update dependencies

• Update nginx in the Docker images to 1.31.8 (Debian) and 1.30.6 (Alpine)

• Update test dependencies with security fixes (ecdsa, idna, soupsieve, urllib3)

8.0.0 2026-11-02

Breaking:

• Drop support for Python 3.10, 3.11, 3.12 and 3.13. MapProxy now requires Python 3.14

Improvements:

• Add support for Python 3.15

Maintenance:

• Raise minimal Pillow version to 13.0.0 because of security fixes
