Yes I've been thinking about this too. As far as i can tell v0.10.x
was the last release to support ARMv5 due to changes in the V8
JavaScript engine. One thing i have been wondering is if we need to
support multiple versions of node.js or just 4.1.x? The node.js LTS
working group here https://github.com/nodejs/LTS/ seems to say that
0.10.x and 0.12.x are still being maintained but supporting only the
latest version would be simpler. What do you think?

I went off this announcement for V8
https://groups.google.com/forum/#!topic/v8-users/aSOFbaAQvMk where it
states the minimum is now ARMv6 with VFPv2. It was the no-VFPv2 port
that was removed but i don't know if it also requires any ARMv6 or
higher instructions. The node.js configure script only seems to check
form ARMv6 or ARMv7, see
https://github.com/nodejs/node/blob/master/configure#L616. So i
assume node.js and V8 need a minimum ARMv6 instruction set.
Thanks
