Blue Iris Updates - Official Thread 6.0.8.6

I have two BI 6.x setups in completely different locations (and separate host computers) which have worked fine for ages. Both have up to date annual updates with auto-renew. Recently both were updated and they both reverted to evaluation mode seemingly forgetting the registration codes. I managed to get one of them up and running again with the code which I purchased 2 years ago but is in fact the code for the other system which is of less importance. On the other I have emailed support twice but so far no answer as need the original code seeing as it was some 11 years ago and not sure where the email has gone. On one of them I also noticed the camera groups setup had mostly been deleted so I had to recreate them and reassign to the users. I did assume the registry backup and restore would restore the keys and fix the groups but apparently not.

I am hoping support will answer soon as been several days. But has anyone else seen this?

Thanks - John

I updated to v6.0.7.2 and lost all my camera groups. Does anyone know how to get back the groups. I did downgrade to v6.0.7.1 and the camera groups are still missing

Take a look at this post a few weeks back re an update messing up groups @jaydeel then produced a PS script to check and review your groups within the registry a few posts later

6.0.8.6

Undocumented under-the-hood change

Starting with v6.0.8.6 (6/30/2026), Blue Iris now uses a rolling 3-second average when calculating the bitrate macros %k and %007. Ken has also confirmed that the FPS macros %f and %006 were similarly updated. He noted that the changes were suggested by AI.

Previously, the calculation was based on 10 one-second buckets of frame data.

Users graphing these macros should expect smoother values than in previous releases, even though the underlying camera behavior is unchanged.

It's worth noting that these macros represent values measured and averaged by Blue Iris from the received video stream, not values reported directly by the camera.
