Version 0.2.14 fixes a few glitches in wallet and enhances I2P support. I'll see how to make the website more clear respectively such questions.
I recommend at least version 0.2.11 released in 2021. In fact, some older versions are compatible with current network too, but can work not so stable in practice. Also it's the minimum version that can work with current Tor network.
