Today we would like to let everyone know that with the release of version 0.25, the 32-bit client will be discontinued. Please note that there will be no support or updates for this version going forward.
However, you may still access the last supported version by switching to the following branch on Steam:
0.23.5.1-32bit - No updates - Windows 32bit - 0.23.5.2
IMPORTANT: If you are unable to upgrade to a 64-bit operating system make the transition prior to the release of version 0.25 to ensure that your game will remain playable.
This decision will allow us to free up development time and enable us to take advantage of newer technologies. According to our data, less than 0.5% of users are still using 32-bit operating systems.
If you are still using a 32-bit operating system we strongly advise that you upgrade to 64-bit if your hardware allows, as this will improve the security and performance of your system.
If you’re not sure which version you use or need help with upgrading, please check this article for more information.
