libstdc++ finally supports C++11's ! My team will be able to ditch boost regex once GCC 4.9 hits a stable version of Ubuntu.

It is also nice to see more parity with Clang when it comes to diagnostics and ASan/UBSan.

Only six months since 4.8 was released. Is GCC moving to a more regular release schedule?

It's 2014, we can now have colored output! Will error and warning messages get unique id's with explanatory/accompanying documentation in 2034?

Seems like competition from clang led to some really practical improvements.

GCC 4.9 hasn't yet been released (and won't be until after Easter). Currently there's only a release candidate. See http://permalink.gmane.org/gmane.comp.gcc.devel/135470

What's wrong with every every 6 months? It's not like bug fix releases aren't dropped in the meantime.

This is huge- you can now do this on a laptop

I think that was the point... every 6 months being better than every 6+dx months as seemed the case before.

I don't personally notice a change though, IMHO releases have been fairly consistently released since the 4.0 timeframe.

That was a point release. 4.8.0 was released over a year ago.
