[ANN] Crystal 0.21.0 released!

[Matías García Isaía]

Crystal 0.21.0 has been released!

- Changelog: https://github.com/crystal-lang/crystal/releases/tag/0.21.0

- Usual installation methods: https://crystal-lang.org/docs/installation/index.html

This release brings many bugfixes, with some additions to the standard library and a bit of cleanup in the standard API.

Highlights:

- The compiler now reuses previous macro run compilations so {{ run(...) }} is only re-run if the code changes

- String can now hold invalid UTF-8 byte sequences, and they produce a unicode replacement character when traversed

- Slice can now be read-only

- Added HTTP::Multipart and HTTP::FormData (thanks @RX14)

Also, the contributing guidelines have been updated - please check the CONTRIBUTING.md file in the repository.

As always, refer to the changelog for the complete list of changes.

Happy crystalling!

• Added String#scrub and String#valid_encoding?

Awesome, I actually reached for those exact two just last week, now I can sweet.

As a note, I'm seeing that sometimes changes to ".ecr" files I use in a kemal projects aren't seeing updates "take" is that related I wonder? It's odd sometimes it works sometimes it doesn't (before, I thought it always did...).

Thanks all!
