Hello everyone, I am not good at English, this is translated by translation software. I have some problems. 1. Why does pkgsrc have so many branches? 2. The machine is Thinkpad X60, i386 processor, I want to install fcitx5, 10.0 branch does not have fcitx5-configtool, 10.0_2023Q4 does not have fcitx5-chinese-addone, I installed these two software in two branches respectively, but they cannot be used, what should I do? Thank you
