Unity 2017.2 You scoff at us

I want to ask you guys developers, you there in your mind? Why after every update to the new version there are new critical bugs?
I Upgraded today to version 2017.2 and build for ios has completely stopped working.
UnityLinker failure… bhla bhla bhla…
Yesterday everything worked on version 2017.1
WTF?

Go on… What the fck with cache server? It hangs up and freezes Unity completely when switching platform.

Soon you will be hated by developers for numerous bugs, I regret that once your engine was chose and made 3 projects on it, now I have to suffer with your engine.

Are you just ranting/venting or trying to report a bug?

Firstly, there was already a bug report on the first problem.
And secondly - I’m tired of doing a bug report. I did this all the time, 3 long years, but nothing changes, why should I waste time on bug reports if nothing happens?
Where is quality control? Why should I do their work?

Tell me please, they could not check the CacheServer? Or they could not verify the build system for iOS? Why do I check it?

Sounds like you’re ready for Unreal.

The irony is good, but I switched to Unreal already at the beginning of the year. I have 2 projects on it in development and there it’s a pleasure to work, the number of bugs with each new release decreases, and not like here.

Nothing breaks in new releases, everything works stably under any platform.

Glad to hear it’s working out. Best wishes in your development.

The solution of the first issue found. If someone faced with any failures of ios or android build process, you need to delete Library folder of the project completely. Then restart, wait a couple of eternities and go on.
What happened with CacheServer I still dont know. Investigating…
