The latest release has some interesting features like handling list of files as input, PCRE support, more readline-like bindings at the in-built prompt, lazy unmount, auto-proceed on open option (very handy when you are opening files one after another).
The keybind `e` to edit a file in `EDITOR` has been restored on multiple user requests.
Along with pre-built packages there's a static binary to download and run `nnn` without installing.
