#2From the release notes http://varnish.org/docs/5.0/whats-new/relnote-5.0.html "It is important that people understand that Free and Open Source Software isn't the same as gratis software: Somebody has to pay the developers mortgages and student loans."
Varnish is an excellent piece of software, but I thought it was totally funded by the commercial side varnish software. How does this model work? It seems odd to ask for donations while also selling an expensive supported version?

A one or two orders of magnitude greater speed, lots of configurations for caching policies, the ability to split a request in several subrequests (ESI) and some other nice things.

"Until now Varnish Software has done a lot of work for the Varnish Cache project, but for totally valid reasons, they are scaling that back and the project either needs to pick up the slack or drop some of those activities."
Why they are pulling back is anybody's guess. But it sounds like they are focusing on monetizing the existing codebase instead of further developing it.

#6Historically, PHK was a very vocal criticizer of SPDY and HTTP/2: http://www.varnish-cache.org/docs/trunk/phk/http20.html
Of course he relented and implemented SPDY and HTTP/2 anyway.
But all the same I can't help but feel that his original criticsm still stands, and what we need is a rethink of e.g. cookies.

#7It's always good to see new stuff coming out for Varnish. Do these changes warrant a major jump in release numbers especially when HTTP/2 support (biggest feature) is experimental?
Anyway, I'm looking forward to testing it out and integrating v5 with Cachoid ( shameful plug: https://www.cachoid.com/ ).

Faster and far more configurable, the configuration language (VCL) compiles to 'C' and you can inline bits of C if you want.

Not sure if the performance gains are still valid. There's reports that state the contrary: https://deliciousbrains.com/page-caching-varnish-vs-nginx-fa...
Nginx has something similar to ESI called SSI (http://serverfault.com/questions/406103/main-differences-bet...)

#10Do I understand this right?
It supports HTTP/2, but doesn't support HTTPS. Therefore it supports HTTP/2 in a mostly unusable form, because browser vendors (for good reasons) decided to support HTTP/2 only over HTTPS.
