- Drop support for Internet Draft 24.
- Code cleanup.
- [BUGFIX] Send HANDSHAKE_DONE only after Finished is received.
- [BUGFIX] Don't treat garbage UDP padding as library error; ignore
it instead.
- [BUGFIX] Fix compilation on FreeBSD (missing header).
- [BUGFIX] Do not delay ACKs for Initial and Handshake packets.
- [BUGFIX] Send PATH_CHALLENGE if path changed before mini conn promotion.
- Logging improvements.
- http_client: discard data faster.

- [API] Drop support for ID-23.
- [BUGFIX] Set key phase bit on outgoing packets correctly.
- Code cleanup.
- [API] Drop support for Q039.
- Improve ACK-queuing logic. Send an ACK once in a while if
peer keeps on sending non-ack-eliciting packets.
- Improve Alt-Svc string: Q050 and later are not included in
the old-style "quic" string.
- Send stateless resets if connection could not be promoted.
- Schedule MAX_DATA if needed when DATA_BLOCKED is received.
- Use ls-qpack 0.11.2 -- needed for server push optimization.

- [OPTIMIZATION] Generate random bytes in batches.
- Change loss_bits transport parameter ID to 0x1057 following latest
draft.
- Randomize period with which PINGs are sent to elicit ACKs.
- Some refactoring and code cleanup.
- [BUGFIX] Invalid read when parsing IETF transport parameters
(this was benign).
- [OPTIMIZATION] Frame bundling when using buffered packets in
IETF QUIC: a) flush QPACK decoder stream and b) include ACKs
in opportunistic fashion.
- Fix HTTP/3 framing unit test.
- Code cleanup.
- [BUGFIX] Initial packet size check for IETF mini conn applies to
UDP payload, not QUIC packet.
- Support old and new school loss_bits transport parameter.
- Use Q run length of 64 as suggested in the loss bits Draft.
- Undo square wave count when packet is delayed.
- Code cleanup; minor fixes.
- [HTTP3] Verify number of bytes in incoming DATA frames against
content-length.
- [HTTP3] Stop issuing streams credits if peer stops opening QPACK
decoder window. This addresses a potential attack whereby client
can cause the server to keep allocating memory. See Security
Considerations in the QPACK draft.
- [BUGFIX] Mini conn: don't shorten max packet size for Q050 and later.
- [BUGFIX] Init IETF connection flow controller using correct setting.
- Code cleanup and minor fixes.
- [FEATURE] Use occasional packet number gaps to detect optimistic
ACK attacks.
- [BUGFIX] Q050 client: all packet numbers are in the App PNS.
- [OPTIMIZATION] Merge multi-range ACK frames, not just single-range
ACK frames.
- IETF QUIC: use RTT estimate in ack timeout calculation.
- IETF handshake: abort conn when unexpected errors occur.
