We are not able to see Robot Manager 8.7.3 version in Market place as per the documentation of RM upgrade, only 8.7.2 version of RM is available for download.
Will RM 8.7.3 version be available for download from market place ? or we have to go ahead with 8.7.2 version of RM.
Pega Robot Manager is aligned to Pega Platform minor releases but not to the patch releases. You can use Pega Robot Manager 8.7 with any of the Pega Platform 8.7 patches.
Pega Robot Manager 8.7.3 patch is due to be released in the next few weeks but it is NOT available in the Pega Marketplace or in the Pega Software download site.
