addedNew Content:New Exhibit: The Maquoketa Formation! This is the first Ordovician-aged exhibit to open in SHADOWBOX, clocking in at around 445 million years old. On display here are fossils of Ampyxina bellatula , a blind trilobite!
addedNew Content:New Exhibit: The Winnica Formation! Hailing from the Silurian of Poland, this exhibit displays fossils of the oldest known vascular land plant species, Cooksonia pertoni ! Paleobotany fans will enjoy examining these 432 million-year-old ancestors to all trees, shrubs, flowers, grass, and more.
addedNew Content:New Exhibit: The Onondaga Limestone! A new addition to the Devonian crypt, this exhibit features fossils from New York that are around 380 million years old. This includes Dalmanites , a trilobite with prominent compound eyes; the coral genera Synaptophyllum and Heterophrentis ; and finally, two beautiful Paraspirifer shells.
addedNew Content:New Exhibit: The Kerch Basin! The final new exhibit in this batch is significantly younger than the rest, and represents our first Miocene exhibit. It displays ~10 million year old fossils of the seal Monachopsis pontica , discovered in the Crimean Peninsula of eastern Europe.
changedEnhanced Features:Texture streaming has been significantly improved in this update, which should lead to overall better performance across hardware configurations! In particular, look for gains in FPS, loading times, and hopefully a stark reduction in VRAM-related crashes.
fixedBug fixes:One loading screen fun fact typo was corrected.

-One loading screen fun fact typo was corrected.

Final thoughts:

This is a belated birthday update, and one that I and the rest of the team are celebrating as hopefully a big step forward in improving accessibility of SHADOWBOX for those with older and budget hardware. Game performance is as much an accessibility issue as anything else, so I encourage anyone who has tried the game at least once before to load it up again and see if 2.3.0 has improved the game on your end!
