Lastline Defender and Analyst Hosted Release Notes

Version 2023.2.1

Feature Depreciation

  • Explicit proxy feature with TLS encapsulation will cease by 2023.3 release.
  • To ensure a satisfactory level of security, it is not advisable to use Windows 7. As a consequence, testing the maliciousness of files in this environment is no longer deemed relevant. Therefore, we have decided to gradually phase out the analysis of files on Windows 7. With this latest release, file analysis on Windows 7 will become optional. All analysis on Windows 7 will cease by January 2024.

Bug Fixes and Improvements

  • SENT-3787: Fix to a bug in the lastline_test_appliance codebase where certain tests would fail due to unexpected decoding issues.

Deprecation of API Methods

The Lastline API documentation includes a deprecation schedule for deprecated Lastline API methods, as well as information on how to replace usage of these deprecated methods with supported methods.

Sensor version 1220 was the final version to support Ubuntu Xenial as our operating system distribution.

The "Base Distribution" listed should be "bionic". If it is "xenial", the appliance distribution needs to be upgraded. For help on the upgrade process, please refer to the following instructions.
