Mozilla heeft enkele dagen geleden een nieuwe development milestone klaargezet van de Firefox 3-branch, die ook wel bekend staat als Gran Paradiso. Ondertussen zijn de ontwikkelaars al aangekomen bij de vierde alphaversie van Firefox 3.0, die vanaf deze ftp-map gedownload kan worden voor onder meer Linux (8,2MB), Mac OS X (17MB) en Windows (6,3MB). Gran Paradiso is de codenaam van de volgende tak van Mozilla Firefox die gebruikmaakt van Gecko 1.9 als engine om webpagina's te renderen. Firefox 3.0 alpha 4 wordt geleverd met een groot aantal veranderingen, waaronder verbeteringen in de gebruikersinterface van de Mac OS X-editie. Daarnaast is de ondersteuning voor offline browsen onder handen genomen en zijn er bugfixes doorgevoerd voor de Gecko-engine. In alpha 4 zat ook ondersteuning voor Growl, maar deze is er op het laatste moment eruit gehaald omdat deze voor een crash zorgde. Wat er allemaal veranderd is in Gran Paradiso Alpha 4 staat hieronder vermeld. De ontwikkelaars zijn inmiddels ook al begonnen aan de volgende alphaversie. Een pre-alpha hiervan kan gevonden worden in de nightly builds, waarvan de volledige alpha eind mei verwacht wordt:
Gran Paradiso Alpha 4 is now available for testing. New features in this development milestone of Mozilla Firefox 3 include the FUEL JavaScript library for extension developers, a redesigned Page Info window, improvements to offline application support and Gecko 1.9 bug fixes.Several Mac OS X additions have also been made, including support for Growl notifications, improvements to the Cocoa user interface and an initial version of the Breakpad crash reporting tool.
Gran Paradiso Alpha 4 is intended for Web developers and the Mozilla testing community only, with regular end users strongly advised to stick with the stable Firefox 2 for now. Alpha releases of Firefox 3 are branded using the Gran Paradiso codename in an effort to discourage regular end users from downloading them.
Gecko 1.9 Alpha 4 introduces several new features which can be tested by using Gran Paradiso Alpha 4:
