In early 2023, the digital privacy landscape was shifting. Many users still relied on older operating systems like Windows 7 and 8.1, even as Microsoft officially ended their support. Version 12.0.4 arrived as a "bridge" release. It introduced significant under-the-hood changes, such as the transition to multi-locale bundles, which allowed users to switch browser languages without downloading a new installer.

However, this version also signaled the beginning of the end for legacy support. Developers warned that maintaining security on older platforms was becoming "hard work" and likened running unsupported software to driving a "car with faulty brakes". By March 2026, official support for these legacy branches finally concluded with version 13.5.29, making 12.0.4 a nostalgic marker of the era when Tor still natively supported the final vestiges of the Windows 7 and 8 generation.
