v1.5.7 - 2018-08-12
* decrease minimum curve radius from 150m to 120m (speed limit was 68km/h now 60km/h)
* increase number of curve radius options from 24 to 27 in each direction
* adjust collision model on far-side mini platforms to prevent collision when an odd number of tracks and nonzero transit tracks are selected
* remove 5m straight track from ends of curved stations to allow truly smooth curves

v1.5.6 - 2018-08-09
* cargo stations (especially with an odd number of tracks) would flatten too much terrain

v1.5.5 - 2018-08-07
* new option to disable station building entirely
* fix road lengths on station building ("left") side, they were always longer than selected
* prevent terrain flattening when that road/entrance not selected
* prevent ugly terrain flattening near station building on sloped stations
* improved alignment of freight station building on curved stations

v1.5.4 - 2018-06-18
* fix game-crashing typo (introduced in v1.5.3)

v1.5.3 - 2018-06-18
* some passenger paths would not connect if station elevation non-zero
* road connection in front of station building conflicted with ground if station elevation non-zero

v1.5.2 - 2018-06-16
* fix minor pathing issue to underground cargo station platforms

v1.5.1 - 2018-06-14
* fix "terminals not connected" with extra-long cargo stations

v1.5.0 - 2018-06-13
* add option to slope entire surface station up to 4 degrees (1 deg ~= 1.75% grade)
* fix "terminals not connected" error on sharply-curved stations

v1.4.4 - 2018-06-11
* fix disconnected underground platforms at non-zero angle when surface tracks are curved
* add option for overall station elevation adjustment

v1.4.3 - 2018-06-10
* underground tracks can be rotated independently of surface tracks
* additional underground depth options to -30m
