04f8f447b2 Release 2.23.0
- [FEATURE] IETF Client 0-RTT support.
- [BUGFIX] Do not schedule MTU probe on first tick.
- [BUGFIX] Parsing DATAGRAM frame.

  necessary is a change to the way we call it in lsquic_engine.  No
  change to the function itself is required.

  (issue #133, issue #167).
- [BUGFIX] Deactivate only *recent* HQ frame, not any HQ frame.

  instead of keeping them in a separate hash, potentially leading
  to mismatches.
- [BUGFIX] Stream data discard infinite loop: break on FIN.

b1a7c3f944 Release 2.20.0
- [FEATURE] QUIC and HTTP/3 Internet Draft 30 support.
- [FEATURE] Unreliable Datagram Extension support.
- [FEATURE] Adaptive congestion controller.
- [BUGFIX] Do not send MAX_STREAM_DATA frames on crypto streams.
- [BUGFIX] Fail with CRYPTO_BUFFER_EXCEEDED when too much CRYPTO
  data comes in.
- [BUFFIX] Spin bit is now strictly per path; value is reset on
  DCID change.
- [BUGFIX] Check that max value of max_streams_uni and
  max_streams_bidi TPs is 2^60.
- [BUGFIX] Close IETF mini conn immediately if crypto session
  cannot be initialized.
- Deprecate ID-28 (no browser uses it): it's no longer in the
  default versions list.
- New programs duck_server and duck_client that implement the
  experimental siduck-00 protocol.  They quack!
- IETF crypto streams: don't limit ourselves from sending.
- Command-line programs: turn off QL loss bits if -G is used, as
  Wireshark cannot decrypt QUIC packets when this extension is used.
- Turn all h3 framing unit tests back on.
- Fix malo initialization when compiled in no-pool mode.

2f2f436324 Release 2.19.9
- [FEATURE] Add lsquic_stream_pwritev().  This function allows one to
  reduce the number of system calls required to read a file from disk
  by using lsquic_stream_pwritev() together with preadv(2).
- [BUGFIX] When stream is reset, it is writeable -- let user collect
  the error.
- [BUGFIX] Calculate correct conn flow control if reading ends early.
- [BUGFIX] Remove stream from read and write queues on internal
  shutdown.  This is a regression introduced in 2.19.7.
- [BUGFIX] Swapped arguments in IETF RESET_FRAME generation.
- Turn off mini conn history when compiling with Visual Studio; this
  allows the project to compile on Windows again.
- http_client: Add -3 flag to stop reading from streams early; code
  cleanup.
- Don't use -Werror.

7483dee074 Release 2.18.0
- [API] Rename "0-RTT" to "session resumption." In IETF QUIC, "0-RTT"
  always refers to early data, meaning a request that the server can
  reply to in the very first return flight.  A more appropriate name
  for what we support on the client site is "session resumption," which
  is standard TLS terminology.  Later, when we add support for 0-RTT
  (early data), we can use the 0-RTT terminology again, this time in
  proper context.
- [BUGFIX] Do not set certificate callback if ea_lookup_cert is NULL.
- [BUGFIX] Make connection tickable when it's marked as closed.
- [BUGFIX] Fail certificate lookup if SNI is not present in HTTP mode.
- Several documentation fixes and improvements.
- Minor code cleanup.

- [FEATURE] QUIC and HTTP/3 Internet Draft 29 support.
- [BUGFIX] Check that scheduled packets are also sendable when
  calculating a connection's "tickable" property.
- [BUGFIX] Don't count scheduled packets as in-flight when pacer is
  checked on tick.
- gQUIC: delay calling on_new for pushed stream until headers are
  available.
- Allow nested calls to lsquic_engine_connect().

- [BUGFIX] Don't warn about dropped Initial packet sequence gaps during
  mini/full handoff.
- [BUGFIX] Send correct conn error when HTTP/3 frame is truncated.
- [BUGFIX] Mini conn: consider amplification when deciding to return
  TICK_SEND.
- [BUGFIX] Don't double-count tag length in amplification logic.
- [BUGFIX] Don't squeeze out lone path challenges.
- [BUGFIX] Log messages dealing with scheduled packet queue squeezing.
- [BUGFIX] don't wipe current path if no path challenge responses
  come back.
- [BUGFIX] When path is reset, don't lose path_id which is used for
  logging.
- Downgrade flow control violations to info log level from warnings.
- Fix connection cap extra check, avoid checks in nested calls.
- Fix some unit tests when extra checks are enabled.
- Use ls-hpack 2.2.1.
- Turn off unconditional extra checks for IETF clients.
- Extra checks: don't verify sent size of hello packets.  Client
  changes DCID length and this check will fail.
