Breaking change in most recent release

  File "/usr/local/lib/python3.8/dist-packages/prometheus_flask_exporter/__init__.py", line 15, in <module>
    from prometheus_client.exposition import choose_encoder

added in 0.14.0 it seems. are you following https://semver.org/?

We are experiencing this issue as well importing prometheus_client from prometheus_flask_exporter. prometheus_flask_exporter has an unversioned import of prometheus_client in their requirements.txt and this latest release of prometheus_client seems to have broken prometheus_flask_exporter. However, this is likely a breaking change for prometheus_flask_exporter, not prometheus_client, no? Updating to a more current version of prometheus_flask_exporter fixes the issue, I believe.

Sorry about this, the breaking change was accidental, and was renamed in #776. I am happy to change it back and created #796.

Note that breaking changes are allowed in 0.x releases, but if it was a purposeful change a [CHANGE] entry would be added to the changelog.

0.14.1 has been released with choose_encoder restored.
