Release Note: JEP 306: Restore Always-Strict Floating-Point Semantics

Floating-point operations are now consistently _strict_, rather than having both "strict" floating-point semantics (`strictfp`) and subtly different "default" floating-point semantics. This restores the original floating-point semantics of the language and VM, matching the semantics before the introduction of "strict" and "default" floating-point modes in Java SE 1.2.
