I'm aware that since I'm using non-cloud Hybris version, self publishing of spartacus libraries will be necessary.
But question is if 6.6x (or any other version 6) is compatible with SAP commerce (on premise) 2205 and production ready? Thanks
It has release version for 6.x and 6.6.x. They already mention that in the document it is compatible with 2005 and never versions.
