After the version jump from 2015 to 2015 in April, Acrobat now was updated to version 2018 after only half a year. But only for the subscription variant (Continuous track). The subscription variant (Classic track) stays with version 2017:
(The update can also be installed using the Acrobat menu Help > Check for Updates….)
Many users have got an automatic update since the corresponding option in the preferences was recently activated by default.
Despite the divergent version numbers all of the new features of this update are available in both variants!
The new Acrobat versions support PDF 2.0. Documents using PDF 2.0 are now opened without a warning. They can also be saved as PDF 2.0. However PDF 2.0 is not supported in Acrobat Preflight (yet). Since Callas has already integrated PDF 2.0 checks and fixups in pdfToolbox 9.4 this feature will certainly soon be available in an upcoming Acrobat update.
Unfortunately Adobe is quiet about which of the new features of PDF 2.0 are supported in the new Acrobat versions!!!
