Beta is a testing and development platform. Users can assist by using beta to test fixes and feature changes before they are made available in regular releases. This assistance and user feedback (including bug reports) is welcomed, but the platform should be considered to be unstable.

Purpose

Betas serve multiple purposes:

• From a user point of view, using a beta and providing feedback is an easy opportunity to be involved in process of improving their favorite open-source softare - an opportunity which requires little or no techincal skill. And because beta gets fixes before release, it is also a place where a user can get relief from problem that has been fixed but not made it to release.
• From a developer and release management point of view, beta is a secondary test bed for patches and features which have already been used in daily build channel. Overall stablility and quality is monitored, so that regressions are found and fixes verified before the code moves to a release version.
• Add-ons authors use the beta channel to develop, update, and fix their add-ons

While beta is considered to be unstable, it is an explicit goal that quality and stability be sufficiently high that the platform be usable by some users on a continuous, daily basis. User feedback helps make that possible.

Installion and updates

You can get the beta from the channel page. Updates occur roughly every 6 weeks, and also on an as needed basis determined by developers and Thunderbird release management. When you run the beta, updates are pulled from the beta channel so that you get beta updates, not release updates. Updates occur every 10 weeks, and also as needed as determined by developers and release managers.

If you want to also run "normal" releases of Thunderbird (also known as ESR releases), you should install the beta in a different directory than the release version. (And when you run your release version, its updates come from the "release" channel", not the beta channel.

• Release - the most stable platform, with major new versions roughly every 10 months, with minor versions every 6 weeks
• Beta - pre-release platform described above
• Daily - is an highly unstable testing and development platform, the intial location where developer patches land for new features and fixes.
