8.1 built on May 22, 2022

  • Breaking Change - by default Admin UI is now running on HTTPS. Default certificate is self-signed so you might need to click through the Self Signed Warning at the first connection. On HTTP port there is now a placeholder that explains this change and also contains the automatic redirect script and button to switch to continue through HTTPS.
  • Added new proxy authentication scheme - Captive Portal. It can be used to authenticate users to modern Microsoft Azure Active Directory (cloud directory) as well as normal on-premises Active Directory and Local Users Database.
  • Added support for Squid 5.5 on Ubuntu 20. The virtual appliance and Microsoft Azure and Amazon AWS images are now based on this version too.

8.0 built on February 27, 2022

  • Added support for Squid 5.2 on Ubuntu 20. The virtual appliance and Microsoft Azure and Amazon AWS images are now based on this version too.
  • Updates of definition files are performed using new updates.diladele.com server. Updates should be faster now.

  • Removed some old settings from Admin UI that are not supported by Squid 5 (for example, no more dns_v4_first setting present).

  • Breaking Change in virtual appliance - default operating system user root is now only able to login using console; remote login using ssh is disabled. This is to prevent security issues in default deployments when administrator forgets to change the default credentials.
  • Improved drill downs in custom reports; reports module is faster (rewritten in golang); Admin UI of Traffic Manager is improved.
  • Dropped Raspberry PI compilation/support; the system is too underpowered for a full scale web filtering solution.
