It is with a blatant denial of the current situation that I announce the next release of Slipshow:

## Slipshow 0.10.0: Don’t look `{up}`

The ~~asteroid~~ star of the release is the new warnings that the compiler can raise to help you write a bug-free presentation. Those warnings are visible on the command-line, but also in the hot-reloading preview in `serve` mode!

Warnings will hopefully help detect bugs in your presentations and improve the experience, especially of newcomers!

This time, I’d like to thanks @Alistair for the incredible [Grace 💅](https://github.com/johnyob/grace) library. Whenever I look somewhere, I find a new OCaml pearl. Thank you for that! This library, the ecosystem, open-source, are all awesome things.

And thanks again to NLNet for [supporting](https://nlnet.nl/project/Slipshow/) the development of Slipshow!
