authcache 7.x-2.0-beta4

This is the fourth beta release of Authcache 2.0. This release fixes a couple of defects but also introduces some noteworthy enhancements.

This release contains substantial changes to some JavaScript files. Be sure to test with a couple of browsers before deployment.

The example.vcl changed slightly (diff). Please review and incorporate the modifications if you operate a VCL derived from this file.

Since 7.x-2.0-beta3 the following changes were introduced:

Outlook

Boost support likely will be moved to its own module before the 7.x-2.0 release. See #2349495: Move Authcache Boost to its own project for the reasons and also join the discussion there if you have an opinion about that matter.

Nginx users might want to subscribe to #2358775: SSI Support.
