Is it safe to upgrade to 3.2.13 or wait for 3.2.14

Hi,

I came across following link:
http://weblog.rubyonrails.org/2013/3/18/SEC-ANN-Rails-3-2-13-3-1-12-and-2-3-18-have-been-released/

which says rails vulnerabilities issue has been fixed in 3.2.13

However I could see another link which says Rails 3.2.13 has induced
Performance Regressions and Major Bugs.
Refer
http://blog.bugsnag.com/2013/03/20/rails-3-2-13-performance-regressions-major-bugs/

I am still not certain for upgrading to 3.2.13.

Please let me know.
