Error on create float window

[kozer]

I build neovim from source (distro: arch, using aur package neovim-git),
and when in logs I get the following error:

2019-03-17T13:02:40.846 ERROR (pid:15685) [model-float] - Error on create float window: Error: request nvim_open_win - Wrong number of arguments: expecting 3 but got 5

Your neovim have incompatible API with current neovim master.
nvim_open_win() should require 5 params.

Shouldn't I build from master?
Running git describe --long I get the following:

warning: tag 'v0.3.4' is really 'stable' here
v0.3.4-413-g9ef8d0d6b

Do I miss something here?

This one seems to change some things, by passing width and height as an option

[chemzqm]

Get it, the api changed.

This should fix it
