Update v5.8.2 & v5.8.3

Changelog for version 5.8.2:

• Adjustment to avoid arriving airplanes spawning too close behind slow airplanes.

• For custom airports:

  • Increased the airspace radius limit.

  • Added 'textpos' property to [areas]; this is for adding centered altitude labels. Older custom airports can keep using the old 'labelpos' (for uncentered altitude text). This change will make everything look the same after updating the game to v5.8.

  • Added new 'label' option to [background], which works similar to the 'text' option, but instead of centering the text at a given position, it is anchored top-left to the given position, similar to how beacons are labeled.

Hotfix v5.8.3 (4 February):

• Fixed a bug (that was introduced in v5.8.2), where boundary coordinates were incorrectly loaded.
