[Solved] Release notes

I agree. It's difficult to find information regarding RB4 release information. It would be useful to have a saved thread for all information related to the releases. If there is already a forum/thread containing the information I'd be grateful if someone could post the link.

As a general rule, I do not perform an upgrade unless there are release notes. Even if there are, sometimes I make a call that the release does not fix something that is specifically impacting my workflow or system stability.

Ver.4.0.3 (2015.11.18)

[NEW]
- CDJ-900 Track Browsing and Waveform Display in HID mode.
- CDJ-400 support.
- Coloured display for played tracks.
- Sampler playback position indication.

[FIXED]
- Cross Fader did not work in EXPORT 2-player mode.

- CUE markers were incorrectly displayed on the CDJ-2000NXS/900NXS/2000 in HID mode.
- Metronome paused in certain situations.
