Hi Barry. Have a look at the toolchain flyer: https://wiki.linaro.org/WorkingGroups/ToolChain/Flyer
At any one time we run a development series and a maintenance series. At the moment these are 4.6 and 4.5 based respectively. When the FSF GCC 4.7 comes out, development will stop on 4.5, 4.6 will go into maintenance, and we'll start up a new 4.7 branch.
We currently only fix issues on tip and make them available in the next monthly release. While we don't support older releases or older branches, the branches are never closed or deleted so you are welcome to submit patches or make your own branch and backport changes into that.
that problem is most users have no toolchain team and no enough resources to work on backporting issues. most people just want to use a "stable" toolchain. so hope the consolidation of toolchain validation can help :-)
I guess the short answer is that for somebody wanting a stable toolchain, picking a release from the 4.5 series is the safer bet, and if you do find bugs, well, report them to launchpad.net/gcc-linaro or to this mailing list.
PS: Michael, can you update the flyer to include the links I suggested we add to the release announcement?
