The CloudStack community maintains two types of releases; the main releases and the LTS (Long Term Support) releases. The LTS releases receive bug and security fixes for a period of 18 months after the main release (for more details click here). The main releases receive only critical bug fixes for a short period. The general expectation is that the users of the main version will upgrade to a new version in order to receive fixes.

It's essential that you verify the integrity of the downloaded files using the PGP or SHA512 signatures. The PGP signatures can be verified using PGP or GPG. First download the KEYS as well as the asc signature file for the relevant distribution. Make sure you get these files from the main distribution directory, rather than from a mirror. Then verify the signatures using:
% pgpk -a KEYS
% pgpv apache-cloudstack-X.X.X-src.tar.bz2.asc
or
% pgp -ka KEYS
% pgp apache-cloudstack-X.X.X-src.tar.bz2.asc
or
% gpg --import KEYS
% gpg --verify apache-cloudstack-X.X.X-src.tar.bz2.asc apache-cloudstack-X.X.X-src.tar.bz2
Please see CheckingSignatures for a more extensive explanation of the pgp verification.
Additionally, you can verify the SHA512 signatures on the files, by performing
% sha512sum --check apache-cloudstack-X.X.X-src.tar.bz2.sha512
For easier installation or upgrades, the official source code release has been supplemented by community members who have chosen to provide package repositories that also include noredis libraries.
Instructions for using these community provided repositories can be found in the Configure Package Repository section of the Installation Guide.
