Since last year (2021H2) we were working with TMF677 release 18.5.1 (v4.0.1) which was marked as "TM Forum Approved". This version was then the most recent one available via TMF product search (it was then highlighted with "Production" header if I'm not wrong).
The newly published TMF677 release 20.5 (v4.0.0) is marked as "Member Evaluation" and from API contract perspective is completely incompatible with previous one. Both documents are tagged with v4, however Usage Consumption is now described as a Task so both operations and resource model has changed.
Now, TMF product search returns nearly identical file released as "Production" (v4.0.0) and marked as "TM Forum Approved". There is also "TMF677A Usage Consumption SID mapping R18.5.1" also highlighted with "Production" header but it doesn't seem to match the new API model.
Many thanks in advance,
