The 0.8.2 update brought a few issues along with the performance benefits. This update fixes issues related to projectiles not being properly reset before being re-used, as well as a few potential crashes associated mostly with improperly initialized arrays.
There are a few notable balance updates as well, such as the fact that only one status effect can be applied per weapon. Upgrades can no longer add properties to a weapon that doesn't have them (e.g. volley enhancers can only apply to weapons that already fire a volley of projectiles) This is part of the upcoming 0.9 changes where weapons will be able to be customized even further in the fabrication menu. There are a few issues I am aware of that will be fixed in the very near future, but this update should hopefully fix any current issues that could potentially result in a crash.
