Really big improvement with this next major version for RocRay :painting:

0.10.0 is the largest change to RocRay so far. The application model has been rebuilt: state changes and drawing are now separate callbacks, slow work runs as tasks without stalling the frame, and the platform gains files, HTTP, UDP, SQLite, subprocesses, screen capture and more

Big thank you to @Romain Lepert for working through lots of different issues and helping shape the APIs and bugfixes.

There is also now a large docs site with a tutorial and introduction to Roc -- which you can download as a PDF if you like. Would love you to check it out and let me know if you find it helpful.

It's enormous ... a lot of the documentation is LLM authored and human reviewed. I hope folks don't mind too much - but I appreciate being able to provide this information and covering a so much more ground than I ever could on my own while also juggling all my other projects.

My hope is that people find roc-ray useful and actively contribute to it or extend it with more features, or go on to build even better Roc platforms. :rock_on:

Also thank you @Pierre Thierry -- we refactored the API completely around capabilities so by default every roc-ray app should now be much more trustworthy.

I also shared on Reddit -- feel free to give it a like to feed the algorithm :smile:
