1. Translations

These release notes are available in the following languages:

2. Introduction

Welcome to the CentOS 5.9 release. CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by our Upstream OS Provider (UOP)1.

CentOS conforms fully with the upstream vendor's redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.) CentOS is a Free Operating System.

CentOS 5.9 is the ninth update to the CentOS 5 distribution series. It contains a lot of bugfixes, updates and new functionality. Before reading any further we advise you to read the UOP Release Notes and Technical Notes2. The rest of this document is an addendum and primarily covers CentOS-specific issues.

7. How to help and get help

As a CentOS user there are various ways you can help out with the CentOS community. Take a look at our Contribute page for further information on how to get involved.

7.1. Special Interest Groups

CentOS consists of different Special Interest Groups (SIGs) that bring together people with similar interests. The following SIGs already exist:

And we encourage people to join any of these SIGs or start up a new SIG, e.g.

7.2. Mailinglists and Fora

Another way you can help others in the community is by actively helping and resolving problems that users come up against in the mailinglists and the fora.

7.3. Wiki and Website

Even as an inexperienced CentOS user we can use your help. Because we like to know what problems you encountered, if you had problems finding specific information, how you would improve documentation so it becomes more accessible. This kind of feedback is as valuable to others as it would have been to you so your involvement is required to make CentOS better.

So if you want to help out and improve our documentation and wiki, register on the wiki or subscribe to the centos-docs mailinglist.
