Probably there are lot of new features introduced in the 6.7 U1 which needs those new API calls.. As you are aware that now VMware has lot of partners integrating with multiple products which might require new api's, rather than delaying they introduced the same in new release with update 1.. It is most awaited updated as far as i can say..
I know this happens with vCloud Director, but at least there was guidance provided for that since there are multiple strains of it.
For vCenter, this is a departure.
It's also not in the release notes. VMware vCenter Server 6.7 Update 1 Release Notes
If this was going to happen, announce it at 6.7.0 and at least give partners time to prepare.
It's also entirely possible I can't find this sort of guidance in a public forum.
But when you have multiple vendors complaining about this (see Veeam and other backup vendors) ... it makes me thing this wasn't planned very well.
Totally agree. The real problem here is that VMware isn't providing partners the pre-release GA code. It's just dumped in their lap as a "surprise" moment same as it is with all customers. This is especially egregious for the data protection partners considering VMware has bowed out of the data protection business altogether after their abomination VDP product (an Avamar pig in lipstick) failed miserably. By them not working with those DP vendors all the way from beta through GA, these types of breaking changes cripple more and more customers until the vendor has a chance to catch up.
