Well, I would not put the "stableness" as the main reason, but rather
that the new toolchains are only for x86_64, hence people stuck with a
32-bit host would be left out. So, we keep the 2014.09 for those in
32-bit land, and add 2015.02 for those in 64-bit land.

Also, I had a look at the latest toolchain, and it seems they've
switched it to a gcc-4.8.:
    http://releases.linaro.org/15.06/components/toolchain/binaries/
which gives:
    $ ./gcc-linaro-4.8-2015.06-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --version
    arm-linux-gnueabihf-gcc (Linaro GCC 4.8-2015.06) 4.8.5
    [...]

while the previous is still using a gcc-4.9:
    http://releases.linaro.org/15.05/components/toolchain/binaries/
which gives:
    $ ./gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc --version
    arm-linux-gnueabihf-gcc (Linaro GCC 4.9-2015.05) 4.9.3 20150413 (prerelease)
    [...]

So, it seems that they are not completely "stable" with their latest
toolchain releases anyway... :-/

However, I'm open to discussion. Hence adding the topic on the list for
the DevDays. If we agree on keeping the old version, the series is
ready. If not, it's easy to chop it down and just do the replacement
with the new version.

Yann E. MORIN.
