acra v0.92.0 Release Notes

Release Date: 2022-03-01 // about 2 years ago

  • 🚀 This release brings stability and performance fixes to AcraServer and AcraTranslator. It officially deprecates usage 🔧 of AcraConnector in favour of TLS everywhere. Some default configuration params are changed in favour of more secure & 👍 better performance settings.

    Core:

    • AcraServer, AcraTranslator:
      • Improved TLS certificate validation performance with CRL. #482
      • Poison record detection turned off by default. Flag --poison_detect_enable changed default value from true to false. #484
      • Removed SecureSession and AcraConnector support as transport encryption. #481
      • Improved and clarified log messages. Removed messages with error level for success cases (not detected poison record), clarified context of messages. #487
      • Added suggestions in log messages how to solve issues with TLS connections. #493
      • Improved in-memory caching keys:
      • Added caching symmetric keys like asymmetric #489
      • Added caching metadata about rotated keys #498
      • Added new flag --keystore_cache_on_start_enable that turns on loading all keys into in-memory cache on startup. #497
      • Changed default value for --keystore_cache_size parameter from -1 (which means no limits for cache) to 1000 (cache items). #497
      • Legacy keys that were used with AcraConnector are now ignored during initial caching on startup. #510
    • AcraServer:
      • The default CryptoEnvelope has changed from acrastruct to acrablock in the encryptor_config. Now AcraServer will use faster encryption by default. You can select which CryptoEnvelope to use in encryptor_config. See AcraStructs vs AcraBlocks documentation, #485
      • Extended PostgreSQL's SQL syntax support with null::<type> type casts. #479
      • Changed the default values for next CLI parameters:
      • --tls_client_id_from_cert changed from false to true. Now AcraServer require app's TLS certificates and map them to keys. #481
      • Improved performance for:
      • querycapture handler in AcraCensor. #483
      • transparent encryption and poison record detection. #487, #496
      • searchable encryption. #490
      • Removed next CLI parameters due to removed AcraConnector support:
      • --securesession_id, --acraconnector_tls_transport_enable, --acraconnector_transport_encryption_disable. #481
    • AcraTranslator: Now AcraTranslator works with TLS by default, it doesn't support AcraConnector anymore. #481
      • Removed next CLI parameters due to removed AcraConnector support:
      • --securesession_id, --acratranslator_tls_transport_enable, --acraconnector_transport_encryption_disable. #481
    • AcraKeymaker:
      • Now handle correctly generation symmetric keys into not existing folders. #486
      • Removed next CLI parameters due to removed AcraConnector support:
      • --generate_acraconnector_keys, --generate_acraserver_keys, --generate_acratranslator_keys. #481
    • AcraKeys:
      • Removed next key types for all commands (generate, read, destroy): transport-connector, transport-server, transport-translator. #481
    • AcraConnector:
