[CentOS] el7: Thunderbird?

Hi Folks,

Just wondering what Thunderbird users are doing on el7 now it's been
removed from the distro?

I note EPEL has a thunderbird package but it seems very out of date at
version 24.5.0. Version 24.6.0 was released 10 June, nearly 6 weeks ago,
and fixed 3 critical security issues. Is this normal for EPEL to be so
far behind on security updates?

The other alternative seems to be running the tarball from Mozilla, but
that is only available in 32-bit and I don't really want to install a
whole bunch of 32-bit libs just to run one program.

So what is everyone else using?
