Bumps github.com/quic-go/quic-go from 0.54.1 to 0.57.0.

Release notes

Sourced from github.com/quic-go/quic-go's releases.

v0.57.0

This release contains a fix for CVE-2025-64702 by reworking the HTTP/3 header processing logic:

  • Both client and server now send their respective header size constraints using the SETTINGS_MAX_FIELD_SECTION_SIZE setting: #5431
  • For any QPACK-related errors, the correct error code (QPACK_DECOMPRESSION_FAILED) is now used: #5439
  • QPACK header parsing is now incremental (instead of parsing all headers at once), which is ~5-10% faster and reduces allocations: #5435 (and quic-go/qpack#67)
  • The server now sends a 431 status code (Request Header Fields Too Large) when encountering HTTP header fields exceeding the size constraint: #5452

 

Breaking Changes

  • http3: Transport.MaxResponseBytes is now an int (before: int64): #5433  

Notable Fixes

  • qlogwriter: fix storing of event schemas (this prevented qlog event logging from working for HTTP/3): #5430
  • http3: errors sending the request are now ignored, instead, the response from the server is read (thereby allowing the client to read the status code, for example): #5432

What's Changed

Full Changelog: quic-go/quic-go@v0.56.0...v0.57.0

v0.56.0

This release introduces qlog support for HTTP/3 (#5367, #5372, #5374, #5375, #5376, #5381, #5383).

For this, we completely changed how connection tracing works. Instead of a general-purpose logging.ConnectionTracer (which we removed entirely), we now have a qlog-specific tracer (#5356, #5417). quic-go users can now implement their own qlog events.

It also removes the Prometheus-based metrics collection. Please comment on the tracking issue (#5294) if you rely on metrics and are interested in seeing metrics brought back in a future release.

Notable Changes

  • replaced the unmaintained gojay with a custom, performance-optimized JSON encoder (#5353, #5371)
