Canon Digital Photo Professional 4 was introduced in June 2014.

Canon has updated its Digital Photo Professional 4 (DPP) software to version 4.1.50. The update brings support for a couple of new lenses and several camera models, improvements to multiple functions, and compatibility with 64-bit native environments, among other things. The newest version, says Canon, incorporates feedback from both APS-C and older full-frame owners eager for 'the very latest Raw workflow solution'.

Version 4.1.50 adds support for both the EF-S 24mm f/2.8 STM and EF 100-400mm f/4.5-5.6L IS II USM lenses, as well as the EOS-1D Mark IV, EOS 7D Mark II, EOS 7D, EOS 70D, EOS 700D, EOS 5D Mark II, and EOS 100D cameras. 

Joining the additional support are general software improvements and additions. Real-time adjustments are faster in version 4.1.50, and the Raw file workflow has been improved. User interfaces are 'more approachable', according to Canon, and there are now color adjustments for specific color gamuts. 

The latest version is available to download from Canon Europe's support website, where it is listed under supported camera models. There you can also see a full list of key features in the latest version.
