OpenRCT2 v0.4.26 "Climbing the North Face of the Uxbridge Road" released!

This September people are literally crawling back to school. Don't worry, we've got something to cheer you up: another OpenRCT2 release!

This one is dominated by rendering fixes but we managed to squeeze in a few of stability fixes and some features.

A big ticket change is we now use Zstandard compression algorithm which should result in both faster load/save times and smaller park files! Read more about it, including how to recompress your parks, on our blog: https://openrct2.io/blog/2025/08/behind-scenes-0-4-26
