Month fact: Airbags in cars sold in Europe are generally smaller and inflate less forcefully than US airbags. This is because European safety ratings are based on belted crash test dummies, whereas US regulations are based on unbelted crash test dummies.

A bunch of stuff added to spt_gui (by @UncraftedName):

Changes:

• Added spt_gui! A very nice GUI that can be used instead of console variables to use some SPT features. Might be still slightly unstable (by @UncraftedName)
• A bug fix to spt gui (by @evanlin96069)
• Fix spt_cam_control locking mouse (by @evanlin96069)

Month fact

A swamp rabbit attacked U.S. president Jimmy Carter's fishing boat on April 20, 1979. The rabbit was hissing menacingly, its teeth flashing and nostrils flared, which prompted mr. president to attack with it using a paddle. The president was unharmed but the fate of the rabbit is unknown. However we can deduce that the rabbit has died, since the lifespan of swamp rabbits is at most 9 years which is less than the 45 years that have passed since the incident.

Changes
