StatsBar
Optimized the statsbar to only run when you open it. This should drastically improve lagassist's performance on 1.13+

Cpu Benchmark
LagAssist relies on PassMark CPU benchmark data to be able to analyze your server. They recently changed their website content which broke lagassist's system used to "read" CPU benchmark results.
It has now been fixed.

StackMob For 1.8
Stackmob had issues starting up on 1.8 due to some of the features used by lagassist not existing in 1.8. Luckily, it's no longer an issue now, as new features are separated from old ones.

Maps, oh Maps!
The world storage system changed drastically from 1.12 to 1.13. While spigot has tried to maintain backward compatibility, there have been some things that didn't work as well between versions. This should now be fixed.
