After one exciting year in Early Access, I am very pleased (and a little proud) to announce the 1.0 release of JOY OF PROGRAMMING and the conclusion of its Early Access phase. This does not mean 1.0 will be the final update. On the contrary: I plan to support JOY OF PROGRAMMING for the foreseeable future and add new levels whenever I have ideas for new challenges. Of course, I also hope the 1.0 release will bring in some new players and our little community will grow with more user made levels (check out the level editor after you're comfortable with the game itself)!

I think it is more important than ever to deepen and widen your programming skills, and game-based learning is great opportunity to do just that.

Happy Coding!

Full changelog over the last year until today:
version 1.0.0
- Added "tinygrad" (https://github.com/tinygrad/tinygrad) to third party modules for deep learning
- Increase virtual RAM upgrades (64->128, 128->256, 256->1024)
- Added new machine: VacuumRobot, automatically cleans up all objects with tag "Dirt".
- Added two new Machine Learning levels: Image Classification and Coin Detection

version 0.9.0
- Added a new level:
- SQL Database (Machine Learning category)
- Preparations for 1.0 release
- Removed "Beta Map" feature.
- Cleaned up some obsolete UI
- Linux/Proton support: Please use Proton Experimental. All levels (including image processing levels) now work correctly under Proton Experimental (but not under Proton 9.03).
- Known issues:
- Localization: While the UI and the tutorials are fully localized in different languages, most other levels do not support localization. These are created with the included level editor which does not support easy localization. Unfortunately, this cannot be easily amended and will not change in the upcoming 1.0 release.
