not seeing it with the beta profile installed.. hmm.

It's not a beta but public official released. Update using iTunes or remove beta to OTA update

 

[atlchamp]

only fix mentioned is the homekit issue

 

[chillip]

Not seeing it yet

Well, it says "iOS 11.2.1 fixes bugs including an issue..." meaning that there are other things that are fixed, just not necessarily called out in the overall release information.

 

[uandme72]

15C153 implies there are many changes since 11.2 which was 15C114.

 

[gwang73]

39 builds since the 11.2 release so I hope there's more fixes than just the HomeKit issue.

15C153 implies there are many changes since 11.2 which was 15C114.

But each change could be as small as a single line of code, or even a couple characters.

It would be a nice Christmas present if Apple solved my home button bug but alas its not to be. My X arrives tomorrow.

I dont think they change the build for each character change.

Or could be some build configuration change or something else similarly effectively inconsequential as far a the actual code and functionality goes.

The build changes if something changes. Could be anything.

Why are we so sure of getting only inconsequential changes.
Is it because of it being a 11.x.x version?

The build changes if something changes. Could be anything.

Then the final beta and the public release should also have different builds.
this does not happen though.

Because 39 build number changes in a 50MB update shows that its only inconsequential.

Second, Why? Why would there need to be a build number change between the final beta and the final release if they are the same exact builds? If they are the same build, developers don't get another update. Because they are the same exact builds. Take 11.2 for example. Exactly the same thing. So why would there need to be a different build number? That doesn't make sense.

Not really saying one way or another, simply pointing out that build numbers don't necessarily always say too much about how much has changed or what impact those changes could have when it comes to the end user.

They’ve been working diligently to find tune all the emoji’s to perfection

[Radon87000]

I really don't think there will be anything gamechanging till 11.3. It's my last hope.

How is it your last hope, you are getting your X tomorrow. Problem solved.

 

[atlchamp]

installed on X seems a bit more fluid but could be placebo

That's true but I would miss the bigger screen. If Apple came out with X Plus I would be all over that.

 

[Mlrollin91]

Usually is. Placebo is a nasty little trickster.

 

[planetf1]

Lack of updates for those on beta may indicate a new beta soon.... Though so close to Xmas I'm thinking not

There are not 39 builds, only 4 builds: 15C150, 15C151, 15C152, 15C153 (release). Apple does change build number to 150 for minor fix updates if they reach to 100+ builds in a major release.

Or, alternately, it took them 39 builds to get the functionality working as expected.

Don't mind, this is all just lighthearted, but we forum members would probably consider as a Christmas present that occasion when the home button delay issue stops getting raised every new thread.

While a lot of us feel it to be a bug, a bug, for all Apple cares, is something that is not working as "they" expect it to. It is clear that Apple intends the home button to work this way in iOS 11, therefore, stands to reason that it will most likely never be resolved for those amongst us who have had the pleasure to experience a near-instant home button on iOS 10.

Nothing can be done about it.
