 ### Writing breadcrumbs to disk in the main thread

 Contributors: @kevinrenskers, @brustolin and @philipphofmann
 
 For the benefit of OOM crashes, we write breadcrumbs to disk; see https://github.com/getsentry/sentry-cocoa/pull/2347. We have decided to do this in the main thread to ensure we're not missing out on any breadcrumbs. It's mainly the last breadcrumb(s) that are important to figure out what is causing an OOM. And since we're only appending to an open file stream, the overhead is acceptable compared to the benefit of having accurate breadcrumbs.

+## Remove the permissions feature

+Date: December 14, 2022

+We [removed](https://github.com/getsentry/sentry-cocoa/pull/2529) the permissions feature that we added in [7.24.0](https://github.com/getsentry/sentry-cocoa/releases/tag/7.24.0). Multiple people reported getting denied in app review because of permission access without the corresponding Info.plist entry: see [#2528](https://github.com/getsentry/sentry-cocoa/issues/2528) and [2065](https://github.com/getsentry/sentry-cocoa/issues/2065).
