Default build is dev version?

Hi,

I am new to px4 firmware development. I fork the master (1.9.2 currently) and clone to my local Linux (Ubuntu 16.04), and “make px4_fmu-v5 default” for my FC board (CUAV pixhack v5), but the console shows: PX4 version: v1.9.0-627-ge25db01. I am confused here. Is there something I need to add when building the firmware to get the latest stable release?

Thanks
Max
