• Gravity surveyor module removed. We can read elevation directly from ship controllers now.
  
• Auto-drop function reworked to use elevation. The command has been changed up a bit. READ THE DOCS.

For example, the following drop command will stop at elevation 500m after initiating braking at 1500m. During the burn phase (while out of gravity), it will use ion and atmo thrusters. During the braking phase, it will use all three thruster types.

Minor PID rework to apply the things I've learned in From the Depths. Re-tuned gyro & thruster PIDs.

Fixed for IMyBlockGroup changes.

• "Start" an optional timer block named "Launch Done" when the "launch start" command finishes (i.e. when your ship leaves natural gravity)
  
• "Start" an optional timer block named "Drop Done" when the "launch auto" command finishes (i.e. reaches the desired stopping altitude)

If resuming cruise after a re-compile or world reload, the first "cruise stop" issued will be equivalent to "cruise reset" -- it will reset all thrusters.

This prevents restoring the thrusters to a disabled state (because they were previously shut off upon attaining the desired speed).

This is a safety/convenience fix since most people probably wouldn't have "cruise reset" on their toolbar.

Updates the Cruise Control module with a subtle change to the "cruise stop" command. See the May 4th Cruise Control changelog.

• Fix bug in Damage Control module that caused it to fail to start properly when re-initializing

Reworked the "gravity surveyor" module a bit. The commands have changed; see the docs.

Can now store multiple planets/moons in a single text panel. The "drop auto" function will use the top-most entry.

Add an "orbit" function that will periodically (1/6th of a second every 3 seconds) align the ship with the gravity vector. Works great with cruise control, especially when flying over smaller planets/moons.

Improvements to Cruise Control module:

• Measure velocity based on frames rather than real time. Makes things smoother when sim speed is erratic.
  
• Add bias factors for asymmetric thruster configs. It should be <1.0 if it favors the thrusters for the forward, left, up directions. >1.0 for the others. Experimental, leaving everything at 1.0 is the original behavior.

Velocity measurement changes also made to VTVL module.
