-# Product Taxonomy Model - Adding "CFTC" value in TaxonomySourceEnum
+# *Technical Change - Update Python generation to utilize the new process*
 
-_Background_
+## Background
 
-A gap has been identified in the model when capturing taxonomy values for commodity underlyer assets as defined by CFTC regulation. Introducing `CFTC` as a taxonomy source is necessary to properly map these values within the model and to support population of the **"Commodity Underlyer ID"** fields in DRR.
+The upcoming release of CDM 7 will standardize the serialization format (Issue #3236) and include a new Python library generated by updated tooling.
 
-_What is being released?_
+## What is being released?
 
-The contribution is the addition of a new `CFTC` value to the `TaxonomySourceEnum` in order to represent the Commodity Futures Trading Commission as a taxonomy source, enabling support for **Commodity Underlyer ID** rules under CFTC jurisdiction in DRR.
+The Python library will use updated tooling that supports metadata.  Python support for functions will arrive in a subsequent update.
 
-_Review Directions_
+Note that the new Python library for CDM 6.x will use the new serialization format that is not backward compatible with data produced by the old Python libraries.  Before standardization, cross-language data exchange (e.g., between Java and Python) was not guaranteed. The new Python tooling facilitates such compatibility by implementing the new format.
