 ### Breaking changes
 
--   the `maybe` combinator's return type changed from returning `T` to `T | undefined`
--   (internal) remove internal namespaces with flat types. `ResultKind.Fail` is now called `ResultKindFail` and so on.
--   added additional type safety (some details available in a1e925bd782a714c28e1fa49ec2cb2792a80ab88)
+-   fix: the `maybe` combinator's return type changed from returning `T` to `T | undefined`. This type is more correct because `maybe` can be called without an argument.
+-   refactor: (internal) remove internal namespaces with flat types. `ResultKind.Fail` is now called `ResultKindFail` and so on.
+-   refactor: added additional type safety (some details available in [a1e925bd782a714c28e1fa49ec2cb2792a80ab88](https://github.com/GregRos/parjs/commit/a1e925bd782a714c28e1fa49ec2cb2792a80ab88))
 
 ### New features
 
 -   add `isParjsSuccess`, `isParjsFailure`, `isParjsResult`. They can be used when testing your parsers.
 -   add example parser for `.ini` files (see the [README](./README.md))
--   add example parser for mathe expressions (see the [README](./README.md))
--   the `or()` combinator shows a clearer error message when it fails
+-   add example parser for math expressions (see the [README](./README.md))
 -   add the `.many1()` combinator, which is like `.many()` but requires at least one match
 -   add `.debug()` method for any parser. It will log the parser's name, the input, the result, and the remaining input. This is useful for debugging. See the [README](./README.md) for more details.
 -   add constant type inference for many parsers and combinators. For example, `const p: Parjser<"a"> = string("a")` is now the default inferred type when using `string()`. Previously, the type would be inferred as `Parjser<string>`. See the [README](./README.md) for more details.

+### Miscellaneous changes
+
 -   failure stack traces are printed on multiple lines
+-   the `or()` combinator shows a clearer error message when it fails
