We deployed some performance enhancements yesterday, so today everyone should have had an easier time updating change of duty status and editing a log event. Both of those processes where improved to run much faster. Most users were experiencing a bad lag time when they were doing those actions. It is much faster now. Let me know in the comments if you have seen an improvement.
Also, some users had an issue with the graph showing up incorrectly when they were crossing time zones. This has been fixed with this deploy.
