I’m pleased to announce the release of ppx\_optint.0.2.0, a small ppx for [optint](https://github.com/mirage/optint) literals. Instead of writing `Optint.minus_one` or `Optint.Int63.minus_one` you can write `-1i` or `-1I` respectively. It may be handy if you write code with a lot of optint literals.

Version 0.2.0 tries to be smarter and will use `Optint.of_unsigned_int32` and `Optint.Int63.of_unsigned_int` over `_.of_string` when possible.
