✔ phpng engine improvements 10-25% performance gain on most realworld applications lower memory usage Cleans up some things for a future JIT ✔ Abstract Syntax Tree ✔ 64-bit integer support on Windows ✔ Catchable "call to member function of non-object" ✔ Various cleanups (remove old ASP/script tags and more) ✔ Null Coalesce Operator ✔ Uniform variable syntax prop getStr(){0} // support nested :: $foo['bar']::$baz $foo::$bar::$baz $foo->bar()::baz() // support nested () foo()() $foo->bar()() Foo::bar()() $foo()() // support operations on arbitrary (...) expressions (...)['foo'] (...)->foo (...)->foo() (...)::$foo (...)::foo() (...)() // two more practical examples for the last point (function() { ... })() ($obj->closure)() // support all operations on dereferencable scalars // (not very useful) "string"->toLower() [$obj, 'method']() 'Foo'::$bar]]> Still early. More things will likely be added First RC scheduled for June 2015
