Adobe has released Lightroom version 6.14, the Last and final Standalone Version of Lightroom, adding some bug fixes and camera and lens compatibility.
Lightroom 6.14 | December 2017
Lightroom 6.14 is the last perpetual, standalone version of Lightroom.
While you may continue to purchase and use Lightroom 6 with a perpetual license, Adobe will no longer provide updates to the software. Consider upgrading to the Creative Cloud Photography plan to get the latest updates in Lightroom Classic CC and the all-new Lightroom CC, and ensure that the software works with raw files from the newest cameras.
The current Adobe CC plan rates can be found here.
