As promised I wanted to give you some information on the update of the Linux+ exams. Officially there are minor changes and I wanted to give you a list of those items in case you are planning to that the exams.
Just as a note the Linux+ certification is run by CompTIA and certification organization that has a number of other industry standard certifications like Network+, A+, and Security+. Another organization, the Linux Professionals Institute (LPI), also has certifications like the Linux Essentials, LPIC-1, LPIC-2, and LPIC-3. https://www.lpi.org/certification/get-certified-lpi/
If you take the Linux+ you can send you information to LPI and get the LPIC-1 certification without having to also take it from them since the exams cover the same information. http://greg.porter.name/wordpress/?p=1128
