[Ellzord]

Update scala version to 2.13.1 so we can use latest features.

Unfortunately Xitrum is using dependencies that do not support Scala 2.13 yet:
twitter/chill#316

Memo:
We may have problem with collections when adding Scala 2.13 support:
https://docs.scala-lang.org/overviews/core/collections-migration-213.html

I will try and keep an eye on these dependencies. It looks like some of them are merged but not yet released.

@ngocdaothanh is this the only dependency?

[ngocdaothanh]

@Ellzord Thanks for the info.

I've just published slf4s-api package for Scala 2.13:
https://github.com/xitrum-framework/slf4s

There's only one more dependency that doesn't support Scala 2.13 yet:
lloydmeta/schwatcher#76

I'll fork and release it for Scala 2.13.

I'm thinking about replacing Schwatcher (not maintained any more) with better-files (it looks very popular):

[Ellzord]

Do you need any additional help?

hello，When can support for 2.13 be completed, is the upgrade in progress?

[ngocdaothanh]

I've updated Xitrum to add support for Scala 2.13.

In a few hours, I'll update related projects (like xitrum-new and xitrum-demos), and post announcement to the Google forum:
https://groups.google.com/g/xitrum-framework

Stay tuned.
