+## [1.2.2] - 2023-02-09
+
+### Fixes
+
+- Arguments with the `.allUnrecognized` parsing strategy no longer consume
+  built-in flags like `--help` and `--version`. ([#550])
+- Fixes an issue introduced in version 1.2.0 where properties with underscored
+  names couldn't be parsed. ([#548])
+- Improves the error message for cases where platform availability causes the
+  synchronous `ParsableCommand.main()` static method to be run on an
+  `AsyncParsableCommand` type. ([#547])
+
