The privacy-centric TAILS Linux distro (The Amnesic Incognito Live System) announces:
Tails 3.0 will require a 64-bit x86-64 compatible processor. As opposed to older versions of Tails, it will not work on 32-bit processors.
We have waited for years until we felt it was the right time to do this switch. Still, this was a hard decision for us to make.
[...] Our current goal is to release Tails 3.0, and stop supporting computers with a 32-bit processor, on June 13, 2017.
Announced February 1: Tails 2.10 is out.
The site's news page (which could REALLY use #FragmentIdentifiers MUCH more effectively) says:
Tails 2.11 is scheduled for March 3rd.

even if the source code is 32/64-bit clean, you have to test the built product. If nothing else there could be code generation bugs in the compiler. I've actually seen these in my work.
It's a lot of labor to test a product as large and complex as TAILS. It's reasonable that they want to focus their effort where it is the most effective.
