v1.0.10

• Defaults to adding PersistentThrust for all parts with ModuleEngines and ModuleEnginesFX
• Adds toggle button on engine parts to activate PersistentThrust
• ModuleManager patch file checks for incompatible KSPIE engines and does not add PersistentThrust to them; doesn't add PersistentThrust to a part if it is already present

v1.0.9

• Recompiled for KSP 1.3.0

v1.0.8

• Update persistent thrust parameters only every 16th physics tick +some logging
• Updated location of KSP Steam directory. Updated Mono compiler to mcs. Load ionEngine patch after NFP to keep realistic maxthrust and electriccharge ratio.

v1.0.7

• Updated to compile with KSP 1.2

v1.0.6

• Recompiled with KSP 1.1.3
• Fixed bug where thrust (and propellant usage) was being applied twice

v1.0.5

• Updated and tested to compile and run with KSP 1.1
• Added DLLs to compile with KSP 1.1: KSPUtil and UnityEngine.UI

v1.0.4

• PersistentEngine now a PartModule, not ModuleEngines; it finds all ModuleEngines on the part and uses them
• PersistentEngine disabled if no ModuleEngines found on the part
• The ion engine patch now matches to module ModuleEnginesFX, due to the same change in KSP 1.0.5

v1.0.4dev0

Development version of v1.0.4. Not ready for production yet.

v1.0.3

• Made densityAverage public for external use

v1.0.2-alpha

• Modularized the physics update in OnFixedUpdate so that intermediate methods calculate and apply the delta-V and resource consumption.
• Intermediate methods are virtual so they can be refined.
• The Orbit.Perturb method didn't use time step size, so it's removed.
