While installing or launching previous versions of Acrobat on macOS 10.14 (Mojave), the following warning messages were displayed:
Acrobat core code base was migrated to 64-bit with the Acrobat DC release in 2015. However, shared components were not migrated then, and that caused these warning messages.
In this release, all the shared components are now migrated to 64-bit for all the Acrobat tracks – DC, Classic 2017, and Classic 2015. As a result, no such warning dialogs are shown during application installation and launch.
In this release of Acrobat, many Mac OS X Deprecated APIs, particularly related to the file system access, are replaced with newer optimized APIs in core areas, such as Viewer, Distiller, Synchronizer, and Plug-ins. It's resulted in a huge improvement (70%) in the application launch time on all supported Mac OS with APFS file system. It's also improved the application’s responsiveness across various features and made it twice as fast as before.
These improvements are available in both DC and Classic 2017 tracks.

Adobe is testing this new PDF sharing experience in Acrobat DC. Therefore, the new experience may not be available to all Acrobat DC users.
You can now sign and certify PDFs in Acrobat DC and Acrobat Reader DC using CryptoTokenKit based smart cards on macOS.
Previous versions of Acrobat have support for digital signature using smartcards based on CDSA and used TokenD modules. Support for CryptoTokenKit based SmartCards is added in this release of Acrobat for both DC and Classic 2017 tracks. The option is available in Application > Preferences.
