Notable Changes

  • MDEV-20469: Plugin dialog could not be loaded (wrong path)
  • ODBC-440: Fixed typo in sha256_password cmake configuration
  • CONC-418: For unknown/not handled schannel error codes FormatMessage function will be used instead of returning "Unknown error" message.
  • CONC-417, MDEV-13492: At irregular intervals older windows versions (prior Windows 10) fail to establish a secure (TLS) connection and return errors SEC_E_INVALID_TOKEN, SEC_E_BUFFER_TOO_SMALL or SEC_E_MESSAGE_ALTERED. This is a bug in windows schannel library and was only fixed in recent versions, also OpenSSL provided a workaround (see https://github.com/openssl/openssl/pull/1350). Since we are unable to fix this, in case of an error during TLS handshake the errorcode Connector/C will try to reconnect up to three times if the error code was SEC_E_INVALID_TOKEN, SEC_E_BUFFER_TOO_SMALL or SEC_E_MESSAGE_ALTERED.
  • Included in MariaDB 10.4.10, MariaDB 10.3.20, and MariaDB 10.2.29
