Scala Toolkit makes Scala powerful straight out of the box

We’ve reached the first milestone for implementing the Scala Toolkit. We’ve talked with maintainers and interested parties and decided on the following libraries: MUnit for testing, Sttp for HTTP client, UPickle/UJson for reading, writing and operating on JSONs, OS-Lib for operating on files and the operating system.

I’m hacking on a small project called sudori, an experimental sbt. The initial goal is to port the macro to Scala 3. It’s an exercise to take the macro apart and see if we can build it from the ground up.

Custom JIT compilation with Runtime Multi-Stage Programming

For a while now I’ve been fiddling with a library called Slinc, a way to link C code in Scala. Originally, I was using Scala 3 macros to produce native bindings and helper code, but I recently discovered that Runtime Multi-Stage Programming produces much more performant code.

As this has been a longer than usual development stretch (between 3.3.0 and 3.4.0), this release contains a large number of significant changes and improvements. Additionally, several improvements that we're very excited about didn't quite make the cutoff and have been pushed to 3.5.0.
