tokio#7874 Lock-free is_cancelled via AtomicBool for CancellationToken. Eliminates >2ms mutex contention in hot paths by replacing mutex with atomic operations.

cloudflare/agents#781 Fix: properly type tool error content in getAITools. Corrects TypeScript type definitions for error handling in Cloudflare's AI agent framework.

hyper#4011 Case-insensitive trailer field matching per RFC 9110. Fixes HTTP/2 trailer header handling to comply with spec requirements for case-insensitive field names.

cilium/ebpf#1945 Add poller and eventRing interfaces for eBPF event handling. Extends the library's event processing capabilities for ring buffer operations.

smoltcp#1127 Check silent_until expiry in Meta::poll_at. Fixes 100% CPU spin when a DNS query times out with an unresolved neighbor by falling through to socket_poll_at once the silence period expires.

smoltcp#1126 TCP challenge ACK for duplicate ACKs in LAST-ACK state (RFC 9293 §3.10.7.4). Fixes silent discard of stale acknowledgments by sending a challenge ACK response.

embassy#5598 Align ring buffer reads to ADC scan sequence length. Fixes channel value shifting after DMA overrun recovery in STM32 ADC ring-buffered mode.

rust-clippy#16402 Fixed false positive lint for proc-macro generated code. Prevents incorrect warnings on procedurally generated Rust code that would otherwise pass compilation.

rapier#806 GeometricMean coefficient combine rule for friction simulation. Implements alternative friction model for more realistic physics simulation in the Rapier physics engine.

RustPython#6661 Fixed set in-place operators with self argument. Resolves bug in Python set operations when operating on self (e.g., s |= s).

floem#1025 Cache whitespace TextLayouts in editor paint. Performance optimization that caches text layout calculations for whitespace characters in the Floem UI framework.

torchcvnn#106 Added input validation to normalization layers. Prevents runtime errors by validating tensor shapes and types in PyTorch complex-valued neural network library.

mitmproxy#8046 Fix modify_body crash when replacement contains backslash sequences. Resolves crash in mitmproxy's body modification addon caused by unescaped backslash sequences in regex substitution.

pySigma#442 Fix chained boolean operators in condition expressions. Extracts all operands from pyparsing results and folds them into a left-associative binary tree, fixing silent drops in expressions like A or B or C.
