Those two changes seem particularly important:<p>* Tails 3.0 works on 64-bit computers only and not on 32-bit computers anymore. Dropping hardware support, even for a small portion of our user base, is always a hard decision to make but being 64-bit only has important security and reliability benefits. For example, to protect against some types of security exploits, support for the NX bit is compulsory and most binaries are hardened with PIE which allows ASLR.<p>* Update Tor Browser to 7.0 (based on Firefox 52 ESR) which is multiprocess and paves the way to content sandboxing. This should make it harder to exploit security vulnerabilities in the browser.<p>What do you guys think about dropping 32-bit?
