A recent update to Adobe CC has added new functions to both Lightroom and Photoshop!
In particular, the new 'dehaze' function should provide a great new tool that will allow you to "remove and/or creatively add haze into your image" in Lightroom CC and Photoshop CC (through Camera RAW).
Another great addition to LR is the addition of a 'black and white' slider in local adjustments (graduated filter, radial filter and adjustment brush), allowing you to "get more precise control over the brightest and darkest parts of your photos".
Some of the photoshop updates look awesome too! check out this video:
