Net geen zeven maanden na de eerste bètaversie hebben mensen van Joomla! de tweede bèta van de 1.5-tak beschikbaar gesteld. Joomla! is een uitgebreide content management system dat op een groot aantal platformen draait en gebruikt kan worden om een weblog, website en/of collaboratiesite te maken. De software biedt daarnaast ondersteuning voor zogenoemde extensions, waarmee de functionaliteit van de eigen site uitgebreid kan worden met bijvoorbeeld statistieken, reactiemogelijkheden en beheertools. Wat Joomla! 1.5 beta 2 met zich meebrengt kan hieronder gelezen worden:
Joomla! proudly presents its most important coding adrenaline surge to the development and designer community. With today's release of Joomla! 1.5 Beta-2, we're shifting gears into turbo mode; an entirely re-factored core, internationalisation, FTP layering, next-generation API and framework that's so flexible and powerful and, of course, a designer's dream for unparalleled templating flexibility.With Joomla! 1.5 the Joomla! project really starts firing on all cylinders. The difference between our current 1.0.12 and the forthcoming 1.5 Beta-2 are not easy to describe, but in essence Joomla! 1.0.x was based upon the Mambo codebase, whereas Joomla! 1.5 has been completely rewritten from scratch. Joomla! 1.0.x was written with "freedom of use" in mind; with Joomla! 1.5 we expanded on this and added "ease of use". This all sounds very nice, but what does it mean? Freedom of use refers to the unlimited possibilities you have when building web-sites, and with ease of use we have tried to make life simpler for the end user, the web administrator and of course the third party developers.
