> People arguing 'its just a beta, it'll obviously change over time': what happened to Apple's relentless pursuit of quality before introducing something to the public? Nothing. They were always pragmatic about it, not "relentless". And it's not a beta. The final version is coming in very short time, so it will be 98% the same. What it is is a FIRST version (iteration) of the new design. It will improve in iOS 8 and…
Wait, you're saying a beta release of ios7 isn't beta? Even if it is mostly the same for gA that doesn't discount it being beta software right now.
Sure, it's beta, as in "buggy, still under development, and not released yet".
What I mean it's not beta in the way the parent mentioned it (and some people use it): that there is any chance in hell it will change in any substantial way.
They might fix some bugs and add/remove a few things, but 99% of what you see now will be there in the fall release.
OS X/iOS betas shown in WWDC are not like some website or app beta that iterates between point releases and can be very different by the time it comes out. They are pretty much baked.
RC would be a better name for it.
