+## 0.2.0 - 2022-12-09
+### Breaking Changes
+- Changed the module interface. ``interrupt_o`` was renamed to
+  ``global_interrupt_o``. Additionally, the module also exposes pin level
+  interrupt signals in addition to the single, globally multiplexed gpio
+  interrupt signal. Existing RTL integrating this IP need to adapt the port
+  list of their instantiations.
+### Changed
+- Change default pad count from 56 to 32.
+- Use the clock gated input stage by default for simulation targets
+- Bump AXI Version
+### Fixed
+- Fix warning about unconnected interface port
