mod-h2 v1.15.11

• mod_proxy_http2: the "ping" proxy parameter
  (see https://httpd.apache.org/docs/2.4/mod/mod_proxy.html) is now used
  when checking the liveliness of a new or reused h2 connection to the backend.
  With short durations, this makes load-balancing more responsive. The module
  will hold back requests until ping conditions are met, using features of the
  HTTP/2 protocol alone. [Ruediger Pluem, Stefan Eissing]

mod-h2 v1.15.10

• mod_proxy_http2: respect ProxyTimeout settings on backend connections
  while waiting on incoming data. [Ruediger Pluem, Stefan Eissing]

mod-h2 v1.15.9

• Since v1.15.4 mod_reqtimeout was enabled for h2 connections. This lead to closing of
  h2 connections when a handshake timeout was configured, irregardless if the handshake
  did happen or not. Added a positive test next to the negative one to ensure that
  mod_reqtimeout is removed after a successful handshake. Fixes #196

mod-h2 v1.15.8

• Fixed an unfortunate regression introduced in v1.15.7 that prevented
  H2_STREAM_ID to be set. Fixes https://bz.apache.org/bugzilla/show_bug.cgi?id=64330
  and Windows crashes reported in https://www.apachelounge.com/viewtopic.php?p=39012#39012.
• Synch with code spell/APLOGNO changes from Apache svn.

mod-h2 v1.15.7

• Fixes issue #195 regarding h2 slave connection ids that resulted in duplicate
  request ids being generated under loads.

mod-h2 v1.15.6

• Fix by Joe Orton for a gcc 10 warnings on s390x.

mod-h2 v1.15.5

• Fixed rare cases where a h2 worker could deadlock the main connection. All the good
  bits in this thanks to Yann Ylavic.

mod-h2 v1.15.4

• Fixed interaction with mod_reqtimeout. mod-h2 was knocking it out completely, however
  it allow configuration of the TLS handshake timeout and that is very useful indeed.
  Also, fixed a stupid mistake of mine that made H2Direct always on, irregardless
  of configuration. Found and reported by [email protected] and
  [email protected]. Thanks!
• Switched test suite and test cgis to python3. A regression in cgi.Fieldstorage() makes
  tests skip chunked uploads at the moment. Sad.
• Merged PR by @mkaufmann that avoids multiple field lengths violations to be logged
  on the same request.

mod_h2 v1.15.3

• fixes Timeout vs. KeepAliveTimeout behaviour, see PR 63534 (for trunk now,
  mpm event backport to 2.4.x up for vote).
• Fixes stream cleanup when connection throttling is in place.
• Counts stream resets by client on streams initiated by client as cause
  for connection throttling.
• Header length checks are now logged similar to HTTP/1.1 protocol handler (thanks @mkaufmann)
• Header length is checked also on the merged value from several header instances
  and results in a 431 response.

mod_h2 v1.15.2

• fixing mod_proxy_http2 to support trailers in both directions. See PR 63502.
