 - `ASDisplayNode, ASLayoutSpec, and ASLayoutElementStyle` now conform to `NSLocking`. They act as recursive locks. Useful locking macros have been added as `ASThread.h`. Subclasses / client code can lock these objects but should be careful as usual when dealing with locks. [Adlai Holler](https://github.com/Adlai-Holler)
 - Introduces `ASRecursiveUnfairLock` as an experiment to improve locking performance. [Adlai Holler](https://github.com/Adlai-Holler)
 - Adds an experiment to shorten init time. [Adlai Holler](https://github.com/Adlai-Holler)
+- Adds a check that Texture is compiled with stdc++11 as specified by the podfile. gnu++11 can cause subtle issues that are currently being investigated. [Adlai Holler](https://github.com/Adlai-Holler)
