New Features
- Adds support for the Envoy HTTP Connection Manager settings headers_with_underscores_action and max_requests_per_connection.
Additionally, adds support for the HTTP Connection Manager allow_chunked_length setting and the cluster-level max_concurrent_streams setting (#5762) - Enables you to force cert rotation, even if the existing certificates are still valid (#5855)
Fixes
- Ensure that enterprise features, when used by an open source user, produce error messages (#4020)
- Remove the Upgradable Plugin interface. This abstraction was a little leaky. Now we handle upgrading plugins in the enterprise application itself, as that is the source of truth for what should be upgraded. (#4367)
- Add a helm option to support running the certgen job on upgrades and installs (#4638)
