Hi Carlos welcome here.
Weekly developer roms are compatible (not with stable), so you can skip some without the necessity of formatting and loosing personal data.

7.1.20 very good ROM, small ram usage compared to previous versions. And btw Google play icon logo went back to normal in my theme in 7.1.19 was very ugly
