In case you missed this, it’s now official. The Nik suite of plug-ins will not be developed in the future. From the banner at the top of the Nik website:
“We have no plans to update the Collection of add new features over time.”
The collection is still free to download and use, but the real question is about compatibility in the future, with either Photoshop/Lightroom upgrades or changes in Windows and Mac core OS versions.
