Only a small number of changes in the LR 12.3 SDK compared to the LR 12.0 SDK:

These parameter names were added:  local_Amount, local_Maincurve, local_Redcurve, local_Greencurve, local_Bluecurve

Undocumented Changes

My automated scripts found the following changes:

photo:getFormattedMetadata ("fileType") and photo:getRawMetadata ("fileFormat") can return the new types "JXL" (for JPEGXL) and "AVIF".

photo:getFormattedMetadata ("trimmedDuration") returns the trimmed duration of a video, as it appears in the Metadata panel.
