Eliot Miranda uploaded a new version of System to project The Trunk:
http://source.squeak.org/trunk/System-eem.930.mcz
==================== Summary ====================
Name: System-eem.930
Author: eem
Time: 9 March 2017, 5:57:44.800851 pm
UUID: bee2dd93-54fa-408c-bf35-fb8b6c842dc5
Ancestors: System-eem.929
Update the VM Stats report to include the more recent macrking vs compaction time, and scavenge threshold data. Break down the uptime in days if running for long enough.
