mod_h2 v2.0.13

• New directive 'H2MaxDataFrameLen n' to limit the maximum amount of response
  body bytes put into a single HTTP/2 DATA frame. Setting this to 0 places
  no limit (but the max size allowed by the protocol is observed).
  The module, by default, tries to use the maximum size possible, which is
  somewhat around 16KB.
  This sets the maximum. When less response data is availble, smaller frames
  will be sent.

mod_h2 v2.0.12

• client resets of HTTP/2 streams led to unwanted 500 errors
  reported in access logs and error documents. The processing of the
  reset was correct, only unneccesary reporting was caused.
• Upgrade requests from HTTP/1.1 to HTTP/2 via the "Upgrade" header were
  always ignored for a request with a body. The check for this was incomplete
  and missed bodies announced via "Transfer-Encoding". Fixed. Refs #243

mod_h2 v2.0.11

• WARNING: the directive "H2HeaderStrictness" from v2.0.4 has been
  removed again. Leading/trailing whitespace in header values is now
  being stripped both for requests and responses. The checks for this
  in nghttp2 v1.50.0+ are now always disabled.
  This means that clients that send leading/trailing ws continue to
  work, but that whitespace makes no difference in processing a request.
  This is the same behaviour as in http/1.1 where the Apache parser does
  the stripping as well (since forever).

mod-h2 v2.0.10

• Extensive testing in production done by Alessandro Bianchi (@alexskynet)
  on the v2.0.x versions for stability. Many thanks!
• refactored stream response handling to reflect the different phases
  (response/data/trailers) more clearly and help resolving cpu busy loops.
• Adding more negative tests for handling of errored responses to cover
  edge cases.
• mod_http2: fixed handling of response where neiter an EOS nor an ERROR was
  received as a cause to reset the stream.
• mod_proxy_http2: generating error buckets for fault response bodies, to
  signal failure to fron when response header were already sent.

mod-h2 v2.0.9

• Fixed a bug where errors during reponse body handling did not lead to
  a proper RST_STREAM. Instead processing went into an infinite loop.
  Extended test cases to catch this condition.

mod-h2 v2.0.8

• Delaying input setup of a stream just before processing starts. This allows
  any EOS indicator arriving from the client before that to take effect.
  Without knowing that a stream has no input, internal processing has to
  simulate chunked encoding. This is not wrong, but somewhat more expensive
  and mod_security has been reported to be allergic to seeing 'chunked'
  on some requests. See https://bz.apache.org/bugzilla/show_bug.cgi?id=66282.
• mod_proxy_http2: fixed #235 by no longer forwarding 'Host:' header when
  request ':authority' is known. Improved test case that did not catch that
  the previous 'fix' was incorrect.

mod-h2 v2.0.7

• fixed idle connection handling for non-async MPMs, like worker.
  With mpm_worker, idle conection could go into a busy loop waiting for
  new data to arrive.

mod-h2 v2.0.6

• fixed handling of connection Timeout setting to not apply when streams
  are still being processed. Adjusted test case expectation.
• referring to #234, adding an explicit close after a request has been
  processed to prevent missing EOS indicators from leaving a stream open
  indefinitely.
• fixed a race condition in end-of-input handling for requests (introduced
  in the v2.0.x line).

mod_h2 v2.0.5

• Synchronized changes from Apache trunk development. Improvements in pollset
  handling and simplification of response data passing to main connection.
• Improvements in shutdown scenarios that wake up a potentially sleeping
  pollset that might block a clean child exit.

mod_h2 v2.0.4

• new directive H2HeaderStrictness (highest|rfc7540|rfc9113) to configure
  the strictness of HTTP header checks. rfc9113 forbids leading and trailing
  whitespace in headers and is supported when building against
  nghttp2 v1.50.0 or newer. The default is the backward compatible
  behavior, e.g. rfc7540.
• Integrated improvements from Apache httpd 2.4.x branch:
  • remove unused and insecure code. Fixes PR66037.
  • preserve the port number given in a HTTP/1.1
    request that was Upgraded to HTTP/2. Fixes PR65881.
