Merge branch 'develop' * develop: Adjusting comments. Adding release notes. Adjusting `AVResultEntryFilter` implementation classes, making sure we adhere to the same principles across both `ResultEntryFilter` and `OngoingResultEntryFilter`. Adding `ChainedRealtimeEntryFilter` which replaces `OngoingRealtimeResultEntryFilter`. Making sure we are not drifting in time with cached realtime tail.
