Today HCL kept their promise and delivered the brand new version V12 – some days BEFORE the official launch on June 7th 2021 !!
All announced language packs, clients and servers are available. The only part missing is HCL Traveler but
I assume that HCL Traveler will be available soon.
UPDATE: HCL Notes Traveler V12 also available for download !!
Here´s the list of the current available language packs:

So with a valid entitlement you should see the V12 installation packs on HCL FlexNet.
