- [BUGFIX] gQUIC: do not destroy critical streams when connection is
closed. See issue #201.
- [BUGFIX] Drop #if LSQUIC_CONN_STATS from lsquic.h. See issue #211.

when malloc fails).
- [BUGFIX] Do not drop incoming data when STOP_SENDING is received.
- [BUGFIX] Receipt of STOP_SENDING should not cause read-reset.
- [BUGFIX] Allow stream writes after receiving RESET.
- [BUGFIX] Typo in stream: ANDing enum with wrong flag.
- [BUGFIX] Reset elision: do not use zero as special stream ID value,
for zero is a valid stream ID in IETF QUIC.
- [API] Add optional on_conncloseframe_received() callback.
- Use zero error code in RESET stream sent in response to STOP_SENDING.
- [OPTIMIZATION] Adjust packet reordering threshold when spurious losses
are detected.
- [API] Pass pointer to local sockaddr to ea_get_ssl_ctx() callback.
- [API, FEATURE] Add es_delay_onclose option to delay on_close until all
data is ACKed. Use new function lsquic_stream_has_unacked_data() to
learn whether peer acknowledged all data written to stream.
- [API] Add optional on_reset() stream callback to get notifications
when RESET or STOP_SENDING frames are received.
- [BUGFIX] On STOP_SENDING, make conn tickable is _writeable_, not
readable.
- [BUGFIX] Check whether ECN counts are set in ACK struct before using them.
- [BUGFIX] Calculate TLP timer correctly when only one packet is in flight.
- [BUGFIX] Min RTO delay is 200 milliseconds, not 1 second.
- [BUGFIX] Memory leak in QPACK decoder handler: discard hset when necessary.
- Allow retired and drained CIDs to be reused after a timeout.
- [BUGFIX] Get rough RTT estimate on receipt of Handshake packet.
This prevents BBR on the client from miscalculating pacing rate,
slowing down sending of ACK packets.
- [BUGFIX] Packets sent during handshake are app-limited.
- [BUGFIX] Bandwidth sampler starts in app-limited mode.
- [BUGFIX] Memory leak: free QPACK handler context in stream dtor.
- Logging improvements.
- [BUGFIX] Allow peer to migrate when its SCID is zero-length.
- [BUGFIX] PADDING size calculation: only one Short packet can be
coalesced. (This should have been part of the fix in 2.24.1).
- Abort connect if received NEW_CONNECTION_ID but current DCID is
zero-length.
- Improve log messages
- [API] Allow use of ea_get_ssl_ctx() on the client (optional). PR #186.
- [BUGFIX] Expand datagram with ack-eliciting Initial to 1200 bytes
after connection promotion.
- [BUGFIX] Discard CRYPTO frames from lower encryption levels after
connection promotion.
- [BUGFIX] Cancel path response if path could not be initialized.
- [FEATURE] QUIC and HTTP/3 Internet Draft 31 support. Drop ID-30
and ID-31 support.
- [BUGFIX] Divide-by-zero in newly enabled conn stats code when no
packets were sent.
- [BUGFIX] Memory leak in gQUIC client when server hello cannot be
parsed.
- [BUGFIX] Server Initial packet size calculation.
- Log user-agent and CONN_CLOSE reason when peer reports error.
- Example programs: Specify ALPN for echo and md5 clients and servers
(issue #184).
- Example programs: Don't add "QUIC_" prefix to lines in keylog file
(issue #185).
- http_server: Fix fd leak in preadv mode; fix preadv() usage when
reading from disk.
- Add QPACK stats collection and experimentation mode, see the new
es_qpack_experiment setting.
- Log busy connection stats every second using the new "conn-stats"
log module.
- Log about skipping only once.
- Update HTTP/3 greased frame type formula.
- Use ls-qpack v2.2.1.
- [FEATURE] IETF Client 0-RTT support.
- [BUGFIX] Do not schedule MTU probe on first tick.
- [BUGFIX] Parsing DATAGRAM frame.
- [BUGFIX] If push promise fails, do not invoke hset destructor.
- [BUGFIX] Client: When connections are IDed by port number, check DCID.
Fixes issue #176.
- Revert the 2.22.1 lsquic_is_valid_hs_packet change. All that was
necessary is a change to the way we call it in lsquic_engine. No
change to the function itself is required.
- [FEATURE] Extensible HTTP Priorities (HTTP/3 only).
- [FEATURE] Add conn context to packet-out memory interface (PR #175).
- [BUGFIX] gQUIC proof generation: allocate buffer big enough for
signature (issue #173).
- [BUGFIX] Make library thread-safe: drop use of global variables
(issue #133, issue #167).
- [BUGFIX] Deactivate only *recent* HQ frame, not any HQ frame.
- [BUGFIX] gQUIC server: associate compressed cert with SSL_CTX,
instead of keeping them in a separate hash, potentially leading
to mismatches.
- [BUGFIX] Stream data discard infinite loop: break on FIN.
- cmake: add install target via -DCMAKE_INSTALL_PREFIX (PR #171).
- Support randomized packet number to begin a connection.
- Mini and full IETF connection size optimization.
- http_client: specify HTTP priorities based on stream conditions.
- [FEATURE] QUIC and HTTP/3 Internet Draft 31 support.
- [API] Let user generate Souce Connection IDs.
- [FEATURE] Allow building lsquic as shared library.
- [OPTIMIZATION] Receive history: use a single contiguous memory
block for everything.
- Deprecate QUIC versions ID-27 and ID-30.
