mod_h[ttp]2 v1.5.2
Recommended update for all 1.5.x users:
- fixed connection shutdown deadlock on linux when client closed early
- beam shutdown does now wait on endpoint to finish using buckets in flight,
hopefully addressing crash issues completely - Since 1.5.1 the internal HTTP/2 protocol is reported as "HTTP/2.0" for
better compatibility and since CGI's SERVER_PROTOCOL seems to require this
format
