Hello Joel, Thank you for contacting RED SUPPORT. I see what you are referring to and am looking into this, but this may be a typo or possibly a beta that got switched over to the release page. We post the differences in the release notes, however we always recommend having the camera on the latest release firmware build since it has the latest feature additions and bug fixes. Some of the major changes between build 5 and build 6 is that with build 6 you have a stills mode so you can toggle between motion or stills, the user interface has changed and it has the additonal OLPF options as well. Overall, build 6 has more fixes and features and is more stable than build 5. The latest build is 6.0.46 which is what we recommend using. Thank you.
