• Measuring a long record takes about a third of the memory. The analysis sidecar now peaks at about 350 MB on a five-minute record, 730 MB on sixteen minutes and 1.2 GB at the thirty-minute limit, down from 770 MB, 2.3 GB and 4 GB. Cue points and loudness figures are unchanged. A thirty-minute record used to be able to get a 3 GiB container killed, which would have taken the station off air.
• A measurement stays readable after the analysis schema moves on, so a later re-measure will not cost any record its cue points or levelling while it runs.
• The image now carries the weights for the analysis sidecar's beat tracker, which adds about 80 MB. Nothing uses them yet.
• New records are now measured for tempo, how far to trust it, and where each bar starts. Nothing on air uses these yet. ANALYSIS_BEATS=off leaves the beat tracker out on a machine short of memory.
• Re-measuring a record can no longer cost it its cue points or level: if the new measurement fails or only covers part of the file, the old one stays. New records are now measured ahead of any re-measuring.
• A record's page now shows its measured tempo and how sure the station is of it.
