+## [0.9.16] 2021-04-06
+### Fixes
+- Arch
+    - not skipping dependency checking when the user opts to proceed with a transaction that would break other packages
+    - AUR: not restoring the CPUs to previous scaling governors after the package is built when optimizations are on
+    - randomly crashing when solving repository packages dependencies (RuntimeError: dictionary changed size during iteration)
