New features:

  • Support of SSL client/server connection: Compared to the MariaDB GPL client library this implementation uses a global (per library instance) SSL context which needs less memory and results in better performance.
  • Read-a-head cache to reduce the system load and time.
  • Added an additional experimental layer to communicate with other databases via plugins, e.g. Sqllite. This feature is disabled by default and not recommended for production use.
  • Dynamic columns support via dynamic column API
  • Support for utf16 character set
  • Documentation, currently available in html format only
  • Graphical installation wizard for Windows platforms (msi installer)

  • Performance schema support for connection attributes
  • Added microseconds support for prepared statements: datetime, timestamp and time to string conversion now return microsenconds

  • IPV6 support
  • allow old password authentication (pre 4.1 passwords)
  • Support for connection timeout parameter on windows platforms
  • New API functions:
