 - Added `limit` parameter to `option().counted()` to limit the number of times the option can be used. You can either clamp the value to the limit, or throw an error if the limit is exceeded. ([#483](https://github.com/ajalt/clikt/issues/483))
 - Added `Context.registerClosable` and `Context.callOnClose` to allow you to register cleanup actions that will be called when the command exits. ([#395](https://github.com/ajalt/clikt/issues/395))
