I realize there might not be a direct answer to this question, but I am wondering if there are any communicated expectations of when this will happen or if anyone can comment on the challenges involved. I understand for instance yum is a major dependency on 2.6, but curious in what ways 2.7 is incompatible.
RHEL 7 includes Python 2.7 and has been out for a while already.
Not only is RHEL 7 supporting and shipping python 2.7, but from RHEL 6.4 and onwards python 2.7 is available through "Software collections".
From Red Hat Software Collections 1.0 product documentation:
This set includes python 2.7 installed in parallel with the version provided by default, installed under
/opt
.There are more software in there worth noting like PostgreSQL 9.2 and Perl 5.16.3.
