Upgrading to httpd 2.4 and documentation - Any missing info? (Apache Users)

Hi Apache users!

A while ago there was an interesting discussion on the dev@ mailing list about the adoption percentage of httpd 2.2 vs 2.4, and I was wondering if the people that have not upgraded yet have suggestion about whether or not the documentation needs any improvement to facilitate the process.

The 2.4 release is the only one actively developed and it offers tons of new features compared to 2.2, among them:

- HTTP/2 support (https://httpd.apache.org/docs/2.4/mod/mod_http2.html)

- <If>/<Else> directives (http://httpd.apache.org/docs/2.4/mod/core.html#if)

- lua scripts support (https://httpd.apache.org/docs/2.4/mod/mod_lua.html)

- most up to date version of the event mpm (https://httpd.apache.org/docs/2.4/mod/event.html)

- most up to date version of mod_ssl

- a lot of bug fixes!

I understand that a lot of you have complex and difficult environments to migrate, but it would be great to extend the 2.4 release as much as possible. Are there any gap in documentation or anything else that we can help with to ease the process?

Let me know!
