format_version of SDK main project files?

[turn2on]

I look at my builds, look at current 440_235 SDK Examples.. And look to the Developer Support section of the site with descriptions, and have various versions in "format_version"..

motherboard_def.lua:
- SDK 440_235: format_version = "2.0"
- My projects: format_version = "2.0"
- Dev Support: format_version = "3.0"
... File format version of the motherboard_def.lua file. Should be "3.0" for this version of the SDK. Required. (description of SDK 4.4.0)

What's right to use? And what if we use 2.0 vs 3.0?


realtime_controller.lua:
- SDK 440_235: format_version = "1.0"
- My projects: format_version = "1.0"
- Dev Support: format_version = "1.0"

Already have answer at new Dev forum:

info.lua:
Version 2.0 is required if the device type is note_player.

motherboard_def.lua:
Version 3.0 is required if your device supports pattern automation.

display.lua:
Version 1.0 is the latest and only version
