Comment (by yawning):

 > We want to be sure users without SSE support won't get an update then,
 for instance.

 Should they get a large clearly visible warning that their platform won't
 be supported for much longer? (In browser UI ideally since enough people
 probably don't read the release notes).

 Anyone using something that doesn't support SSE2 is guaranteed to be on 32
 bit Windows or Linux, and if we ever need to do it, detecting SSE2 support
 is trivial (`CPUID` with `EAX` set to 1, look at bit 26)...
