I uploaded 1.3.1 to mentors and are looking for a sponsor for my upload:
https://mentors.debian.net/package/sentry-python/ <https://mentors.debian.net/package/sentry-python/>
Alternatively, one can download the package with dget using this command: dget -xhttps://mentors.debian.net/debian/pool/main/s/sentry-python/sentry-python_1.3.1-1.dsc <https://mentors.debian.net/debian/pool/main/s/sentry-python/sentry-python_1.3.0-2.dsc>
