+_powerlevel9k/master_ is the stable branch of Powerlevel9k, the one that virtually everyone uses.

+_powerlevel9k/next_ is the development branch for the next release. Powerlevel10k is over 100

+In fairness, Powerlevel9k has acceptable latency when given a spartan configuration. If all you need
+is the current directory without truncation or shortening, Powerlevel9k can render it for you in
+17 ms. Powerlevel10k can do the same 30 times faster but it won't matter in practice because 17 ms
+is fast enough (the threshold where latency becomes noticeable is around 50 ms). You have to be
+careful with Powerlevel9k configuration as it's all too easy to make prompt frustratingly slow.
+Powerlevel10k, on the other hand, doesn't require trading latency for utility -- it's virtually
+instant with any configuration.
