Toolchain Versions

On Linaro Releases the “latest” toolchain is 7.2-2017.11 although there are also 7.3-2018.05 and 7.4-2019.02.
Are these later two not considered stable or is it just that the “latest” simlink has not been updated?

These are stable releases only, see: Linaro Releases

I am not sure which symlink you are referring too. But Linaro Releases points to 7.4-2019.02 release only.

BTW, latest gcc-8 onward tool-chain releases are managed by ARM here [1].

Thanks sumit.garg.
The link I was following was:
https://releases.linaro.org/components/toolchain/binaries/latest/aarch64-linux-gnu/

AFAIK, this link isn’t valid now which makes sense also as latest tool-chain (gcc-8) is being managed by ARM.
