+### Fixed

+- Resolved incompatibility with a dependency's update in `agb-tracker`. If you
+  are already using `agb-tracker`, then this won't yet cause an issue as your
+  lockfile will maintain the working version. However if start a new project, or
+  update dependencies, cargo will choose the later incompatible version.
