Phoronix: GCC 4.5.0 Compiler Released
Version 4.5 of the GNU Compiler Collection (GCC) was running behind with too many regressions being left open, but only a few weeks ago they cleared their P1 regressions and then put out the GCC 4.5 release candidate. Now, already, GCC 4.5 has been officially released...

Yes, LTO is definately the big one this release (particularly since llvm's LTO is only available on the OSX platform). Then we have Graphite, although it was already in 4.4, it was bare-bones and has now been enhanced considerably. Also plugin support has great potential (like llvm's DragonEgg). I'm surprised myself at how fast the gcc 4.5 release came out, here's hoping llvm 2.7 get's past it's critical bugs and releases soon aswell.
Yes I hear you, but making a c++ frontend is hard and it takes time. Meanwhile DragonEgg gives more options to those who wants to use llvm's optimizer rather than gcc's.
