UNRELEASED

⭐️ New

• Dict now supports popitem, which removes and returns the last item in the Dict. (PR #2701 by @jayzhan211)

• Added String.unsafe_cstr_ptr(self) that returns an UnsafePointer[C_char] for convenient interoperability with C APIs.

• Added C_char type alias in sys.ffi.

🦋 Changed

• Continued transition to UnsafePointer and unsigned byte type for strings:
  • Rename String._as_ptr() to String.unsafe_ptr()
  • String.unsafe_ptr() now returns an UnsafePointer[UInt8] (was DTypePointer[DType.int8])

❌ Removed

🛠️ Fixed
