Changelog

Sourced from h2's changelog.

0.4.19 (August 24, 2026)

• Improve default (auto) small DATA frame budget based on configured connection window.

0.4.18 (August 20, 2026)

• Add data_frame_budget(n) methods to client and server builders.

0.4.17 (August 19, 2026)

• Fix limiting of excessive small DATA frames to ignore EOS frames.
• Fix HPACK encoding table to cap the max size to 4kb.

0.4.16 (August 17, 2026)

• Fix limiting excessive amount of small DATA frames.
• Fix double counting pushed streams when receiving 1xx responses.
• Fix releasing of flow control capacity earlier, when RecvStream is dropped.
• Fix missed wakeup in poll_trailers.
• Fix extra memory retained when copying HeaderValues.
• Fix resets received after END_OF_STREAM to allow the data to still be received.
• Fix busy-looping when IO write returns 0 to mean connection closed.
• Optimize HPACK decoding tables from 4-bit states to 1-byte states.
• Optimize IO writing contention by not holding lock while flushing.

0.4.15 (June 15, 2026)

• Fix closing a connection when header size is "way too large" (currently x4 configured limit).
• Fix overflow calculating padding length if a DATA frame had 255 bytes of padding.
• Fix ignoring library-initiated resets in the connection state loop.
• Fix decoding panic with an absurd amount of headers and no limit to now use try_append().
• Fix rejecting frames on streams whose HEADERS have not been sent.
• Fix poll_capacity() to not return Some(Ok(0)).
• Fix discarding of buffered DATA frames when a reset is scheduled.
