1.2.10 has just been released which a bunch of important fixes.
We are also pleased to introduce you a new Windows Installer for the first time.
This one includes all what's needed to get Nicotine+ running on a Windows computer!
Upgrading to 188.8.131.52 is advised. Several bugs in 1.2.5 were fixed, and a (previously unknown) long-standing issue in Windows with invalid characters with directories and filenames was resolved.
