quic-go
A production-ready QUIC implementation in pure Go
Back to changelogNew
v0.58.0
This release optimizes the QUIC handshake:
- Multiple incoming packets are now processed before sending an acknowledgment, reducing the total number of packets sent: #5451
- ACK frames are now packed into coalesced packets, reducing the need to send a separate packet just for the ACK in many cases: #5477
- When packets are buffered during the handshake, this now doesn't lead to inflated RTT measurements anymore: #5493, #5494
Other notable changes
- quic-go now has a new logo: #5484
- ACK frames can now be encoded with up to 64 ranges (previously: 32): #5476
- Serializing ACK frames is now significantly faster: #5476
- Improved batch packet processing logic: #5478
- qlog: added support for the
datagram_id on packet_sent, packet_received and packet_buffered events, using the CRC32 of the packet: #5455
