ObjFW 是一个可移植的、轻量级的 Objective C 编程语言框架。

Changes:

1. fixes double-retain in OFList. 
2. It will not ignore the timeout in OFStreamObserver when using select(). 
3. It performs -[OFURL copy] in a try block to prevent a leak when an exception occurs. 
4. It fixes a too large buffer in -[OFMutableString _applyTable:withSize:]. 
5. It calls madvise() on the correct length variable so that it covers the whole string. 
6. It fixes a warning when sizeof(size_t) < sizeof(long long). 
7. It skips possible BOMs when appending strings
