Massive performance gains and a ton more all arrive tonight on the default branch! We are extremely excited to release the update to you tonight as we close out this long cycle. We hope you find the wait to have been well worth it -- improvements abound with nearly every aspect of the gameplay receiving attention along with the true focus, the main event of the cycle, being the long awaited performance optimizations. See below for the full change logs. :)

What's Next?

We will be getting back to more rapid cycles now that we have taken care of the key foundational concerns that had hampered performance. We still have more performance gains ahead, and we'll continue to make incremental strides, but we're really ready to knock out some new content and additional gameplay systems! Next cycle you will be seeing: Tutorial, Cafe / Retail Overhaul, and Staff Scheduling. As usual we'll slide in a few features, QoL improvements, and fixes too -- but the focus will primarily be on these three areas. You'll be seeing the tutorial hit edge this coming week even! :) Don't forget the Official SimAirport Roadmap to see the whole picture of what to expect!

Thank You!

We want to extend a special thank you to the players on edge & experimental who have been instrumental to making this cycle a successful one. This was the longest cycle to date, and definitely one of the most challenging; we really appreciate the continued testing, bug reporting, and the overall patience that the community as a whole has & continues to extend to us. Your collective support continues to be incredible and is truly second to none. Thank you!!!
