Patch notes for v0.8.7a

* Added new 3D models for T1/T2 Electrolyzers. * Optimized truck buffer balancing when storages or dumping designations are cut off from trucks, which caused FPS drops at high sim speeds (over 10x faster in those cases). * Fixed incorrect layout of height 4 ramp entrances. * Fixed trains planning switchbacks that ignored critical sections when the switchback point was in the middle of a partly critical track piece. * Fixed trains that reversed while holding block reservations never releasing them. * Fixed grade 1:4 to grade 1:8 track transitions being used when building in G8-only mode, they are now allowed only when building from or attaching to a G4 piece. * Fixed path-finding heuristics for tracks with R30 curves.
