====== Introduction ======

**Hyperbola** is under continual development. The current release name is "**Milky Way**". It is also (currently) known by the codename "**stable**".

Each version also corresponds to a set of named software repositories (at least one per CPU architecture).

At any given time, there is one stable release of **Hyperbola**, which has the support of the [[https://www.hyperbola.info/members/security-team/|Hyperbola security team]]. When a new stable version is released, the security team will usually cover it to debug packages, maintain patches imported from Debian and evaluate security threats through the [[https://issues.hyperbola.info|HyperTask]] to help the [[https://www.hyperbola.info/members/developers/|Hyperbola development team]]. Only stable is recommended for use.

There are also a main development repository testing maintained by the [[https://www.hyperbola.info/members/developers/|Hyperbola development team]] which is continually updated during the development of the next stable release. The latest packages arrive in testing (which always has the codename "**White Hole**").

===== Choosing =====

End users should generally choose to run either stable or testing. **Stable** is recommended for applications requiring stability and security (servers, firewalls etc) and is also recommended for those who are new to GNU/Linux. **Testing** is recommended for slightly more advanced users who are capable of [[https://issues.hyperbola.info|reporting]] and fixing bugs to help Hyperbola.
