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 two years (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' will upgrade to a new version in order to receive fixes.
Apache CloudStack's most recent release is 18.104.22.168.
This is current CloudStack LTS release.
Full release notes can be found in the version 22.214.171.124 Release Notes website.
Instructions for building from source and installing Apache CloudStack can be found in the Installation Guide. Instructions for building from source and upgrading from a previous version of CloudStack to Apache CloudStack 126.96.36.199 can be found in the upgrade section of the Release Notes (see above).
It's essential that you verify the integrity of the downloaded files using the PGP or MD5 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
% pgp -ka KEYS % pgp apache-cloudstack-X.X.X-src.tar.bz2.asc
% gpg --import KEYS % gpg --verify apache-cloudstack-X.X.X-src.tar.bz2.asc
Additionally, you can verify the MD5 or SHA512 signatures on the files.
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.
Apache CloudStack's CloudMonkey tool is a CLI and shell environment designed for interacting with CloudStack-based clouds.
CloudMonkey's current release is 6.0.0.
For easier installation or upgrades, the official source code release has been supplemented by community members who have pushed the python package to the Apache CloudStack CloudMonkey Github release page.
