Upgrading?
AI Summary
This release includes multiple improvements for HTTP header quality value parsing, strict validation of WebSocket frame lengths to prevent overflow, and dependency updates.
Key Highlights
- Fix `QualityItem` parsing to recognize quality parameters before other parameters.
- Reject WebSocket frames with invalid 64-bit payload lengths using `ws::ProtocolError::Overflow`.
- Update `zstd` dependency to `0.14`.
- Update `brotli` dependency to `9`.
New Features
- Fix `QualityItem` parsing to recognize quality parameters before other parameters.
- Reject WebSocket frames with invalid 64-bit payload lengths using `ws::ProtocolError::Overflow`.
Full Release Notes
- Fix `QualityItem` parsing to recognize quality parameters before other parameters and ignore semicolons inside quoted values. - Parse header quality values as exact decimals and reject invalid numeric syntax. - Round float quality conversions to the nearest thousandth to preserve all three decimal places. - Reject WebSocket frames whose 64-bit payload length has the most significant bit set, or whose length does not fit in `usize` on 32-bit targets, using `ws::ProtocolError::Overflow`. - Update `zstd` dependency to `0.14`. - Update `brotli` dependency to `9`.
