Breaking changes in Cartographic Information Model V3

Question

Hi team,

I'm writing a python toolbox that uses the Cartographic Information Model (CIM) to retrieve layer symbology.

The docos always warned that ArcGIS Pro 3.0 would introduce V3 of the CIM with breaking changes, but I can't find any info on what those changes are.

So that I can make my toolbox compatible with both V2 and V3, is there any material on this somewhere?

Cheers

Andrew

Thanks Dan, I guess I’ll just have to compare the two CIM docs for each item.

v2 and v3 documentation is here

Esri/cim-spec: This repository hosts the specification for the Cartographic Information Model (github.com)

and some others which may be of interest

Esri/cim-symbol-builder-js: Use the CIM Symbol Builder to explore different combinations of symbol layers and their properties to create your desired CIMSymbol in the ArcGIS API for JavaScript. (github.com)

but I don't see any document citing a simple change list
