June 2025 monthly summary for zenoh-c: Stabilized build reliability under panic='abort' and restored CI stability. No new features were released this month; the focus was a critical bug fix addressing size mismatches in Mutex types when the poison flag is compiled out in certain panic modes. Implemented a safe handling approach using decl_c_type_inequal! to accommodate these variations; commit 7c76c19e6fde19225f6c38f9f553e523cfb848cd ("Fix build with panic=\"abort\" (#1038)"). Impact: reliable builds in CI and production panic configurations, enabling faster iteration and higher confidence in release readiness. Technologies/skills demonstrated: build tooling, macro-based type handling, cross-language build robustness.

May 2025: Stabilized adminspace query responses in ZettaScaleLabs/zenoh by correcting the encoding to application/json, ensuring JSON payloads are correctly interpreted by clients across two reply scenarios. The change improves interoperability, reliability, and client tooling integration with admin queries.
