Colitu Windows v3.1.1

What changed in this release

v3.1.15 November 2026
More reliable automatic connection
Automatic mode now picks servers that better match your network, and the first connection after turning on your PC succeeds faster.
Performance improvements
- Automatic mode now always chooses servers for the network you are really on; connecting through certain servers could make the app treat their location as your own and pick worse servers later, and that no longer happens.
- After a restart while connected, automatic mode now picks the server itself instead of connecting to one that may not work on your network, so the first connection after turning the PC on succeeds faster.
