huh, one day after public beta 5, we have... public beta 6. ios has been experiencing this as well. unusual, no? anyway, just mentioning it...
Actually it was 3 days.
But not unusual when public release is imminent.
Some of the pre-release golden masters were even coming out less than one day since the last one.
I guess developers are used to it because this sort of thing has been happening for years.
If you are new to the public betas it is just something you will have to get used to.
And advice I would give is to download it as quickly as possible and as soon as you find out about it for each beta. If you leave it too long to update you could end up missing a few betas.
Many people missed a few golden masters because they didn't expect them to come out so quickly.
