`:tabedit` now works as an alias to `:edit` with a path and as an alias to `:tabnew` without. `:tabnew` is a new command that opens a new tab with a new file if used without a path and works as an alias to `:tabedit` with one. `:tabclose` now works as a proper alias to `:quit` (i.e. passes the arguments) `:edit` now works more like before - it opens a given path in a new tab. It also doesn't do anything if the file was modified since the last commit, unless forced by using `:edit!` `:write` works properly again and doesn't overwrite files, unless forced by using `:write!` `:xit` is now called `:xit` and not just `:x` `:substitute` now properly replaces multiple groups (`:s/(a)b(c)/X\1\2X\0`)
