Adobe just released the final version of Lightroom 5.2 and Adobe Camera Raw 8.2. Note that ACR 8.2 is compatible with both Photoshop CC and Photoshop CS6.
These updates include several bug fixes and add add support for 16 new cameras, including the Canon EOS 70D, Fujifilm X-M1, and Sony RX100 II, along with new lens profiles.
There are no links yet to download Adobe Camera Raw directly. Adobe prefers users to use the Adobe Application Manager or the Update feature in Adobe Bridge or Photoshop to install the update since its easy to screw up the installation if you're running both 32- and 64-bit versions of Photoshop and Bridge. If I find direct links to ACR 8.2 I'll post them later.
Download: To install Adobe Camera Raw 8.2, use the update mechanisms in Photoshop CS6 or CC.
The full list of new cameras supported by these versions is as follows:
