to the full range of software in the ARM Debian distribution (including GIMP, Iceweasel/Firefox and OpenOffice) via a chroot environment. Derivatives MeeGo In the wake of the release of the MeeGo code base, there are two main community efforts to bring MeeGo to the current Maemo devices (N800, N810, and N900), as Nokia has launched the N9, which is powered by MeeGo. These efforts are the MeeGo adaptation for the N800 and N810 devices, and the MeeGo to N900 project. Harmattan Harmattan was originally planned as a transitional operating system developed by Nokia, meant to be a bridge between Nokia's Maemo and the MeeGo project. It is still using the APT package manager for applications, but the graphical user interface and major parts of the system were improved, rewritten from scratch or rebased on top of Meego frameworks. It is heavily using the Qt libraries instead of GTK+/Hildon, and introduced a new UI paradigm based on Swipe gestures, done from the edge of the screen. After problems with the original Meego project, Nokia decided to rename Harmattan to Meego/Harmattan and shipped their N9 with this OS. Mer Mer is a completely free and open-source software distribution targeting mobile and embedded systems, first developed for reimplementing Maemo in the open, and then rebased on top of the MeeGo tools. Qt In January 2008, Nokia began the process of acquiring Trolltech, the developer of the Qt application framework. Nokia has since announced plans for the Qt libraries to be bundled with Maemo by Q4 2008, though without a platform-specific "hildonized" user interface as is offered with GTK (meaning Qt applications will look different from hildonized GTK applications). This will make porting of Qt applications to the platform easier for developers, and make new applications available to users. Qt support on S60 devices will likely lead to cross-platform application sharing between the two platforms. The announcement has been met with mixed reactions in the developer community. Release history Naming Maemo codenames are named for winds. For example, the latest release, codenamed "Fremantle", is a reference to the Fremantle Doctor, the Western Australian vernacular term for the cooling afternoon sea breeze which occurs during summer months in south west coastal areas of Western Australia. *: Hacker Editions, Nokia-released, but community-maintained. Primarily used by developers to continue developing programs while using older hardware. Maemo Summit In 2008 and 2009, Maemo developers and users gathered at
