Key Features

Added

  • Added a comprehensive redesign of the Settings page with improved user interface and enhanced functionality across all tabs including Users, Roles, Certificates, Connections, Security, Vault, License, and Advanced settings.
  • Added comprehensive security improvements including password history, expiration policies, forced admin resets, IP whitelist/blacklist functionality, and automatic account disabling for inactive users.
  • Added connector creation date tracking to provide better visibility into when connectors were originally created.

Changed

  • Improved support for FIPS 140-2 compliance to meet stringent federal security requirements for cryptographic operations.
  • Improved User Roles to relax the maximum role restriction for a user, and the maximum policy restriction for roles.

  • Improved the performance of the cleanup procedure.
  • Improved the performance of the application database by leveraging partitioning when SQL Server is used.
