D is a modern C-style programming language, declarative, object-oriented, and with inferred static typing, somewhat inspired by Python, Java, Eiffel, C# and Ruby. It provides many conveniences, like automatic memory management, concurrency-awareness, contractual design, or first class arrays and dictionaries, built-in macro and meta programming features. It still permits inline assembler, and produces fast and native binaries.
major feature: Destructors for structs allocated on the heap are now invoked. ASM statements can now be used in pure, nothrow, @nogc, or @trusted code. Package protection attribute can be optionally bound to specified package. The garbage collector got faster. volatileLoad and volatileStore intrinsics were added. Experimental: The garbage collector can now be configured. byKeyValue was added. initOnce was added to perform thread-safe lazy initialization.
