Airport CEO Beta 4 
Happy weekend, airport CEO!
It’s time for the fourth beta version deployment, beta 4, building upon and stabilizing the very many and major changes we deployed as of beta 3. We’ve for some time now wanted to get back to our more fast-paced and agile beta development schedule which ties back to the two week sprint periods we originally announced. With beta 3 being such a major release and taking an unexpected amount of time, beta 4 and the other forthcoming betas will most likely move a lot quicker as demonstrated by this release.
Unlike beta 3, this update mainly focuses on continued bug fixing and stabilization with some minor exceptions. Please refer to the full release notes below and the update notes list further down detailing this update’s most important points.

Update notes
Water!
As a result of notable community demand and requests for this feature, beta 4 brings water to the world of Airport CEO. New maps, where climate applicable, will generate small ponds and lakes and you can also yourself beautify your airport surroundings with the new water tile.
In-world data overlays
This update contains a new in-world data overlay system which we’ll over the remainder of the beta period extend with various data sets, including heat maps. First out is a person walkability overlay that is intended to show you exactly where persons can and cannot walk.
Context panel
We’ve added a context panel to better communicate relevant controls and symbols as you perform certain actions. If you’re ever in doubt of what you’re looking at you can give it a quick peek to remind yourself.
Have we forgotten anything that needs a context panel like this? Let us know in the comments and we’ll see if we agree with you! 
And of course… loads of bug fixes and balancing
Most important in this update is the continued bug squashing and system balancing. Since this update mainly builds upon the large changes introduced in beta 3, beta 4 will be a lot more stable. We’ve fixed all issues you’ve reported on rooms not activating, franchise staff leaving on load, parking lots not being used and much more.
Work on beta 5 will begin next week and we hope to deploy its contents just prior to the end of the year and the holiday break. A dev blog detailing the beta period ahead and what the full release for ACEO will look like in 2021 will drop late tomorrow evening.
Thank you as always and have a great rest of the weekend!
