The latest version of Dreamweaver, 2017.5, is now available for download and install through the Creative Cloud desktop application. It usually takes around 24 hours for the update to be reflected in the app, so if you are unable to see it, log out and sign into the CC desktop app. If you still don't see it, wait for a few more hours before you post your observations here.
The 2017 releases of Dreamweaver CC brings in several new features and enhancements including support for Git, an all-new code editor, more intuitive user interface with a selectable dark theme, and several enhancements including an improved onboarding experience.

I am locking this post so that we can continue discussions on this release under more relevant headings.
