Jun 1, 2026June 2026 monthly summary for google/quiche: Delivered a critical bug fix to QUIC MTU discovery when SoftMaxPacketLength is set lower than the current MaxPacketLength. The fix ensures the first probe packet size is calculated correctly, allowing MTU discovery to increase MaxPacketLength reliably and preventing probe failures. The change is guarded by the quic_fix_mtu_discovery flag and addresses edge-case behavior reported in issue #107.

Nov 1, 2025November 2025 monthly summary for google/quiche: Removed QuicPerPacketContext from QUICHE, simplifying packet processing and removing an unused context tied to the deprecated UDP proxy. The change aligns with the UDP proxy deprecation in GFE and ensures the codebase no longer creates or relies on QuicPerPacketContext. Implemented via a focused commit; verified no creation paths exist in GFE and updated related code paths as needed. The work consolidates maintainability gains and reduces potential runtime checks and dead code exposure. (PiperOrigin-RevId: 836355177)
