+### Bug Fixes
+
+* **cs2-modding:** keep the game's mscorlib on Linux, so a mod using spans or tuple deconstruction builds ([77105d0](https://github.com/CitiesSkylinesModding/agents-plugins/commit/77105d01d6d59da47892bd17b1da0a585c65f140))

+* **unity-devtools:** report a held debugger slot, and name the advertised port when an attach fails ([cf97321](https://github.com/CitiesSkylinesModding/agents-plugins/commit/cf973218ef6a39cb38462f9d6178b99e1ac3a636))
+
+
+### Bug Fixes
+
+* **unity-devtools:** make failed evals name what failed, and refuse entity() past the store's bound ([28544c2](https://github.com/CitiesSkylinesModding/agents-plugins/commit/28544c2a5ffaab4528a5e5bd6b2269ef2133db40))
