Do you have AppleScript in your InDesign workflows? InDesign is hosting an Office Hours special tomorrow.

Original post from the InDesign Developers Prerelease* quoted here:

Developer Action Required:
Review all AppleScript-based event handlers in your workflows.

Inline handlers using globals, arguments, or helper functions should be refactored to use external .applescript files.

Keep logic self‑contained within the handler script to maintain compatibility with the modern framework.

Hi there! Obviously I’m late to this and did not attend the meeting. I have several legacy INDD Applescripts running in our enterprise and was hoping for some followup. So the breaking changes are certain to be coming? Can you say which InDesign release these changes will occur (would help greatly in scheduling refactoring time for the scripts)? And is this applicable to pure AppleScript apps and scripts, or JS/Applescript hybrids? I’m really sorry to have missed the meeting!
