Adobe has released updates to Photoshop CC and CS6 that include Camera Raw 8.4 and more – and announced that the next update to Photoshop will not support Flash-based extensions such as Mini Bridge and Kuler. The Oil Paint Filter is also for the chop.

It's in the nature of software development – especially subscription-based tools that are iteratively developed – that as well as adding new features, sometimes companies kill off older features that are barely used, poorly implemented and/or use code bases that the developer doesn't want to support any more.

In this vein, Adobe has posted on its Photoshop blog that it's 'retiring' certain features when the next, as-yet-unannounced version of Photoshop CC is released. The key technology that's being dropped – perhaps surprisingly – is Adobe's own Flash, which developers could use to create additional panels that added extra tools.

Adobe introduced HTML5-based panels in Photoshop CC, so developers can still create extensions – but Flash-based panels will no longer work, including Adobe's own Mini Bridge and Kuler. The company says it's working on an HTML5 version of the Kuler colour scheme-building panel, but hasn't said whether it'll be released at the same time as the Flash version is killed off.

The Oil Paint filter is being removed because it relies "on a very large and complex code library used for an outdated technology (Pixel Bender) that is no longer supported".

The next Mac version of Photoshop will also work on Mac OS X 10.7 or higher, removing support for OS X 10.6. Adobe notes that users can update to OS X 10.9 for free, though this isn't possible for some older Macs.

For users who still rely on Flash panels, OS X 10.6 or want the Oil Paint filter, Adobe will still let you download that version.

Camera Raw 8.4

Camera Raw 8.4 is available for Photoshop CS6 and CC, though CS6 users get only new camera and lens profiles and bug fixes. Photoshop CC users get some useful new features too.

The update adds split-screen previews (above) for directly comparing edits to the original, replacing the old Preview button. You can also reset local corrections, change the grain effect from image to image (for image sequences such as time lapses), and remove red-eye from animals.

New cameras supported include Canon EOS 1200D, Casio EX-100, DJI Phantom, Fujifilm X-T1, Hasselblad H5D-50c and HV, Nikon D3300 and D4S, Olympus OM-D E-M10, Panasonic LUMIX DMC-ZS40, Phase One IQ250, Samsung NX30 and Sony's Alpha a5000 and Alpha a6000 (ILCE-6000).
