Missing from the changelog:

 From 2.208:
2804 Impure nested functions should be legal inside pure functions

 From 2.209:
std.math:
Intrinsics std.math.yl2x and yl2xp1 added. Improves performance of 
std.math.log() and similar functions (and they are now pure nothrow).

(Yes, I know, not very exciting compared to Andrei's new Phobos <g>).
