Now available: Varnish Cache 5.0, now with HTTP/2 support

Yesterday the Varnish Cache project released the first version of Varnish Cache 5.0 with experimental HTTP/2 support. We're pretty excited about it, as is the community of Varnish Cache users. Varnish Cache 5.0 features changes to some (mostly) internal APIs and adds new features from Varnish 4.1. These changes include things like separate VCL file and VCL labels, ban lurker efficiency improvements, changes from hit-for-pass to hit-for-miss, among other things. Probably the most anticipated of Varnish Cache 5.0's new features is support for HTTP/2. It's experimental in that it works (test it out!) but is not being used in any big production sites yet.
