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.

9c4445241e Release 1.19.3
- [BUGFIX] Q044: don't encode packet number in 6 bytes.  Six-byte
  packet number encoding does not exist in Q044.  This fixes a
  regression introduced in '[BUGFIX] Buffered packets can contain
  ACK frames' -- we need to keep QUIC version in mind when selecting
  the longest possible packet number encoding used for the buffered
  packet that carries the ACK.
- [BUGFIX] Do not increase CWND when timeout occurs.
- http_client: support setting handshake timeout on command line.
  Use -o handshake_to=timeout.
- http_client: use -k to connect UDP socket to pick up ICMP errors.
- http_client: allow pathless mode, when only handshake is performed
  without issuing any requests.  This can be done by simply not
  specifying a -p flag on the command line.

8ca33e0e19 Release 1.19.0
- [FEATURE, API Change] 0-RTT support.  Add function to export 0-RTT
  information; it can be supplied to a subsequent connect() call.
- [FEATURE] Add -0 flag to http_client to exercise 0-RTT support.
- [BUGFIX] Resuscitate the Windows build.
- [BUGFIX] Send HTTP settings (max header list size) if necessary.
- [BUGFIX] Buffered packets can contain ACK frames.
- [BUGFIX] Make packet writeable once all STREAM frames are elided.
- [BUGFIX] Fix potential null dereference when realloc fails.
- cmake: simplify build configuration.

6aba801d42 Release 1.18.0
- [API Change] Can specify clock granularity in engine settings.
- [BUGFIX] Pacer uses fixed clock granularity.  Since the change on
  2018-04-09, it is not necessary to try to approximate the next tick
  time in the pacer: it can use fix clock granularity specified by
  the user.
- [BUGFIX] Do not tick constantly before handshake is done.
- [BUGFIX] Do not exit tick prematurely: reuse packet with ACK.  Even
  if we cannot allocate *more* packets, we could still be able to write
  to one already allocated.
- [BUGFIX] Do not schedule pacer if there are no lost packets.

4d83f5bd45 Release 1.17.15
- [BUGFIX] http_client: make sure only one read per on_read() callback
  is performed in the header conversion bypass (-B) mode.
- http_client: with -E, assign random priority when stream is created.
- [OPTIMIZATION] On immediate write, place an ACK frame into the first
  buffered packet if an ACK is queued.  This reduces the number of
  standalone ACK packets.
- [OPTIMIZATION] Allow placing more than one STREAM frame from the same
  stream into an outgoing packet.  This change minimizes the number of
  buffered packets required to store several small HTTP messages by
  virtue of allowing more than one STREAM frame from HEADERS stream in
  the same packet.
- [OPTIMIZATION] Flush headers when writing to buffered packets.  This
  causes the headers to be written to the same buffered packet queue,
  thereby improving packet utilization, especially for small HTTP
  messages.

19f667fba5 Release 1.17.14
- [FEATURE] http_client can now collect stats: time to connect, TTFB,
  time to download, requests per seconds, and bandwidth.  See -t flag.

- [BUGFIX] http_client: -B, -K, and -r can be used at the same time.

- [BUGFIX] http_client: do not display cert chain before each request.
  Now this is only done once per connection, if the handshake is
  successful and -a option is given.

- [BUGFIX] Do not wait to dispatch on_close() after reading.  If a
  stream is scheduled to be closed after on_read() callback returns,
  close it immediately instead of waiting until the end of the tick.
  If client creates new request from on_close() event, they will be
  processed in the same tick instead of waiting for the next one.

- [BUGFIX] HEADERS stream is critical: always treat it with highest
  priority.

8252b0b935 Release 1.17.6
- Add failsafe: resume sending packets after some time

  The change puts a 1-second limit on the amount of time the engine
  will not send packets after some packets are delayed.  This makes
  the library robust in case the user does not unblock the engine
  explicitly using lsquic_engine_send_unsent_packets() call.

- [BUGFIX] Handle corner cases in send controller when packets are
  a) delayed or b) dropped during repackaging.

- [BUGFIX] Memory leak: destroy buffered packets during controller
  cleanup.

3229dd1160 Release 1.14.3
- [BUGFIX] Do not abort conn on STREAM frame for a reset stream
- [BUGFIX] Drop packets that would become empty due to repackaging.
  Packets on the scheduled queue may be marked for repackaging.
  Frames such as ACK frame that are never resent are removed from
  repackaged packets.  We must check that the newly repackaged packet
  would not be empty.  If it would be, it is destroyed instead and
  the next packet on the scheduled queue is used.  Note that this
  change only affects the logic to return the next packet to be sent.
  Lost packets that are being rescheduled are already processed in
  this fashion.
- Byteswap CID before logging it - this makes it match Chrome CIDs.
  (Except Q035, which is the last little-endian GQUIC version we
  support.)

14e3680d6b Release 1.14.0
- [API Change] Disable packet sending if full batch cannot be sent
  If lsquic_packets_out_f() cannot send the whole batch, disable
  packet sending until lsquic_engine_send_unsent_packets() is called.
- [BUGFIX] Handle case when STREAM frame does not fit.
- [BUGFIX] Always allow incoming STREAM frames to overlap.  Peers
  may send overlapping STREAM frames even if using versions older
  than Q043.
- Custom header set fixes:
  - set "FIN reached" flag when custom header with FIN flag is
    claimed;
  - do not return custom header set for a reset stream.

3b55e6ae0a 1.13.0: [FEATURE, API Change] HTTP header bypass
Add ability to create custom header set objects via callbacks.
This avoids reading and re-parsing headers from the stream.

to turn it on).

- 1.10.1

  This avoids a problem of accumulating a very large list of packets
  (possible when speeds are high and socket's receive buffer is large)
  and processing it all at once.
- If glibc is older than 2.17, link with rt.  This is necessary for
  clock_getres(2).
