No Lua SDK for Lightroom Classic v15?

Hi. I noticed that the Lua SDK version for LrC that is available in the Adobe Developer console is still stuck at v14.3. Will there not be a SDK release for v15?

 

I am hoping that all of the new AI and assist features might be getting better scripting support.

 

(Also, maybe finally API support for image stacks...though that probably will never happen 😉 )

Since Adobe doesn't do a great job of keeping the documentation timely and up-to-date, I regularly run Lua discovery scripts on new versions, looking for new functions, methods, and keys. For LR 15.0, I found just one new function:

 

LrApplication.addHapticObserver

 

I haven't tried to figure out what it does, but I'm guessing it can monitor presses and pressure of stylii and tablets. It's a companion to the undocumented LrApplication.addKeyModifierObserver(), which I did figure it years ago -- it lets you track the up-and-down state of modifiers keys like Shift and Ctrl.

I just downloaded SDK 15.1 resources.

In the past many years, Adobe has released new SDKs sporadically, perhaps once or twice per major version, well after the .0 of the major version is released.

Can LrApplication.addKeyModifierObserver() also detect the status of the Caps Lock key?
