Changed
- All samplers are now async and run on-demand when a metrics endpoint is hit.
Percentiles must now be calculated from the free-running histograms. (#334) - BPF is now non-optional on Linux. (#336)
- Makes HTTP compression dependent on client accept headers, removes the need
for separate configuration of compression. (#337) - Removes histograms for counter and gauge metrics. (#338)
- Histogram grouping power reduced from 7 (0.781% error) to 3 (12.5% error).
This reduces the memory footprint for each histogram. (#339)
