747be414e2 Release 2.8.4
- [HTTP3] Verify number of bytes in incoming DATA frames against
  content-length.

  ACK frames.
- IETF QUIC: use RTT estimate in ack timeout calculation.
- IETF handshake: abort conn when unexpected errors occur.

ff892190dd Release 2.7.3
- [DEBUG] Further dedup next advisory tick messages when reason is
  the same.
- [BUGFIX] Update size of `a` array in TP struct.  Fixes (benign)
  GitHub bug #94.

a137764bf2 Release 2.7.2
- [BUGFIX] Send controller: update scheduled bytes when DCID length
  changes (IETF client).
- [BUGFIX] Drop alarm check from sanity test.  It no longer works now
  that we use loss chains.
- [PORTABILITY] Fix build on Alpine Linux.
- [PORTABILITY] Fix build using XCode.
- Client initial DCID length: use RAND_bytes() instead of rand(3).
- Add unit tests for connection min heap.

Dmitri Tikhonov
936463fe29 Release 2.7.1
- [BUGFIX] client: don't call ignore_init() in middle of batch send.
  ignore_init() makes an assumption that the send controller has access
  to all outgoing packets.  This change wraps a few IETF full connection
  methods to delay calling ignore_init() until the engine returns all
  outgoing packets that were batched.
- [BUGFIX] set errno to EAGAIN if sendmmsg() can't send all of them.
  This needs to be done because the value of errno may be lost on
  some platforms.
- [BUGFIX] Typo that set all bits in sm_qflags lead to crashes.
- [BUGFIX] Do not cancel header block processing after failure, as
  QPACK releases the reference in that case.
- [CLEANUP] IETF encrypt: replace assert(0) with a warning.
- Several small improvements to the test server.

Dmitri Tikhonov
7ee4152504 Release 2.7.0
- [API, FEATURE] Close connection immediately when ea_packets_out()
  fails with errno != EAGAIN.  The API change is that errno is now
  examined.  Make sure to set it if using something other than
  sendmsg() to send packets.
- [CLEANUP] Immediate close logic in IETF full conn.
- [CLEANUP] Fix bogus warning about uninitialized `pair' variable.

Dmitri Tikhonov
84dbbb75d5 Release 2.6.1
- [BUGFIX] set retry token on all resubmitted packets.

428530e38e Release 1.19.6
- [BUGFIX] Ensure that Largest Observed does not decrease in ACKs we
  send.  ACK frames placed in packets in buffered queues (optimization
  introduced in 1.17.15) can be preceded by an ACK frame generated later.
  In this case, the older ACK frame should not be sent out, as Chromium-
  based servers flags decrease in the ACK frame's Largest Observed value
  as an error.
