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.

For the record, you can get 64-bit processors that don't have TPM and IME (and AMD's equivalent of IME). There are real reasons to go 64-bit only, including security improvements, like NX bits and increased memory space, and cutting down on bugs and workload for the developers. However, I question whether the tradeoff is worth it, given what the user base of TAILS happens to be from their figures versus what people imagine it is. But I can see their assessment going the other direction. Worst case scenario, I can see a fork where people just do minimal fixups and recompilation of TAILS source to keep 32-bit stuff going.
