i have not used this new build released today. but their betas have been very buggy wrt periods. i mean you manually select a word and spacing is messed up. you have to end up using the spacebar or the delete key for spacing (between words and between words and comma/fullstop). i checked the reviews and i can see that i am not the only one facing this issue. swiftkey handles spacing perfectly.
looks pretty. swiping typing is still pretty good. my only issue is that accessing special characters is hard. i use special characters in lots of my passwords so i have to dig deep. swiftkey makes them more accessible.
