September 2025: Zenoh stability enhancements focused on eliminating deadlocks in session management. Implemented Zenoh Session Deadlock Fix by releasing the session lock before potentially long-running listener callbacks, preventing deadlocks when removing MatchingListener from the session state. This change improves reliability under load and reduces latency spikes during listener processing.

August 2025: Focused on stability improvements in cross-platform PTX loading for cubecl. Implemented a data-type compatibility fix by switching PTX data storage from Vec<i8> to Vec<c_char> in PtxCacheEntry and in load_ptx, ensuring consistent data representations across platforms and cudarc expectations. This resolves platform-specific differences and reduces PTX load failures, enabling more reliable GPU kernel execution. No new user-facing features delivered this month, but the change improves reliability and accelerates future feature work for CUDA-backed workloads.
