CraftOS-PC 2 is getting closer to release, adding some of the final features to be implemented. This will hopefully be the last beta build (next will be release candidate). This release also is the first to fully pass CraftOSTest (in the repo root), indicating full API compatibility.

In this build:

  • Both forms attach the computer peripheral to the current computer
• Added modem peripheral
  • Still WIP, expect some bugs
• Added GIF recording support
  • Press F3 to toggle recording
  • Shows red circle in corner while recording
  • Limited to 15 seconds for performance reasons
  • Saves to ~/.craftos/screenshots/<time>.gif
• Added coroutine override to partially solve some problems in #1
• Moved Windows install directory to 64-bit Program Files
• .craftos directory is now created on boot
• Reimplemented fs.find, fixing #4 (fs.find returns {} on Windows)
• Added some CC: Tweaked features
  • #16 (Add monitor.getTextScale())
  • #24 (Add automatic HTTPS requests)
  • #25 (Add term.nativePaletteColor())
  • #29 (Make os.time() and os.date() case-insensitive)
• Moved all dynamic libraries into Mac app (fixes dyld errors)
• Added switch to auto-run script (--script )
