=== {{Anchor|SCL}}Add-ons releases ===
Software Collections (SCL) is a CentOS [[Software repository|repository]] that provides a set of [[programming language]]s, [[database server]]s, and various related packages. Provided software versions are either more recent than their equivalent versions included in the base CentOS distribution, or are made available as official CentOS packages for the first time.<ref name="software-collections-1.0-release-notes">{{Cite web |url=http://dev.centos.org/centos/6/SCL/docs/ |title=Software Collections 1.0: Release Notes |website=centos.org |url-status=dead |archive-url=https://web.archive.org/web/20131102000443/http://dev.centos.org/centos/6/SCL/docs/ |archive-date=2 November 2013 |access-date=30 October 2013 |df=dmy-all}}</ref> (See also the list of CentOS repositories [[#REPOS|below]].)

Packages available from the SCL do not replace the default system tools provided with CentOS. Instead, a parallel set of tools is installed in the {{Mono|/opt}} directory, and can be optionally enabled per application by using supplied {{Mono|scl}} utility. For example, the default versions of Perl or MySQL remain those provided by the base CentOS installation.<ref name="software-collections-1.0-release-notes" />
