v2.2.0-Release notes

This is a minor release for ProxySQL 2.x series containing several important features, fixes and enhancements.

New features and enhancements

• Added a feature to evaluate query annotations for prepared statements. #3453
• Added synchronization support for global ldap-% variables and mysql_ldap_mapping provided by Enterprise 'ldap_auth_plugin'. #3419
• Temporarily added session_track_schema to ignore_vars until proper support is added. #3442
  • NOTE: This just means that ProxySQL for now is going to just ignore session_track_schema. The absence of error when using this variable doesn't mean that it's supported.
• 're2' library is now compiled with -fPIC. #3405
