## [Unreleased]
+TODO... writeup `truststore` switch & 3.10+ requirement.
+
The 0.28 release includes a limited set of backwards incompatible changes.
**Backwards incompatible changes**:
* The `verify` argument no longer accepts string arguments.
* The `cert` argument has now been removed.
-* The `SSL_CERT_FILE` and `SSL_CERT_DIR` environment variables are no longer automatically used.
+* The `SSL_CERT_FILE` and `SSL_CERT_DIR` environment variables are no longer automatically used. They can be enabled manually although should be obsoleted by our switch to `truststore`.
For users of the standard `verify=True` or `verify=False` cases this should require no changes.
