Revision as of 11:07, 29 January 2009

Fremantle is the codename of the Maemo 5 release. It comes after Maemo 4.1 (Diablo) and before Harmattan.

Fremantle timeline

This is a timeline based on known events and announcements. Many dates are quite flexible at this point.

• 2008-06-01: "Fremantle" codename announced in LinuxTag 2008. See maemo LinuxTag update.
• 2008-09-17: First annoucements in OSiM World: OSiM News: What's up with Maemo? (Ari Jaaksi, Head of Maemo Software @ Nokia) & Get ready for 2009!OSiM World 2008 (Erkko Anttila, Maemo SW Fremantle product manager, and Quim Gil, Maemo SW open source advocate).
• 2008-09-19: More announcements in the Maemo Summit 2008 - Summary: What can we get out of Fremantle (slides) (video), by Peter Schneider (Maemo SW head of product marketing)
• 2008-12-08: First pre-alpha SDK and first report on API changes. Suitable for platform development only.
• 2009-01-29: Second pre-alpha SDK with Media Application Framework and more new platform components.

Expected:

• Plan for a presentation in FOSDEM FOSDEM about Fremantle running in the BeagleBoard.
• Plan for a mature alpha SDK with new Hildon application framework and API freeze available around February 2009.
• Bossa conference in March. Maemo activities tbd.
• Beta SDK released between March-May, ready for application development including support for Mozilla based browser and Greasemonkey add-ons.
• Qt 4.4 "garage" support and Theme Maker by Urho Konttori planned to be ready by the beta SDK release.
• Final release when ready.  :)

New

• High definition camera support
• OpenGL ES
• Clutter
• Meta Tracker
• PulseAudio
• GUPnP
• OHM
• upstart
• A2DP & AVRCP support
• OpenMAX

Changes

Toolkit

• New and updated Hildon/Gtk widgets.
• Gtk 2.0 library upgraded to version 2.12
• Glib upgraded to 2.16
• Pango upgraded to 1.20
• Cairo upgraded to 1.6.4
• gcc upgraded to 4.2

UI Framework

Fremantle introduces a new UI framework which uses Clutter OpenGL library. It provides the following functionality:

• Window manager
• Task Launcher
• Task switcher
• Home view
• Status menu and status area
• New Hildon notification API for handling desktop notifications.

Media Application Framework

A new framework that provides high-level components to developers to ease the task of writing media player applications by abstracting them from the details of low-level components. Thus, it allows them to focus on the UI design and development. The framework also eases the development of 3rd party plugins, similar to GStreamer, but on a higher level.

Data management

Tracker introduced to replace libmetalayer.

Connectivity

BlueZ

BlueZ updated to version 4.x. Brings along a major redesign of the D-Bus API and local bluetooth service framework. The main benefit of this change is decreased code complexity both on the BlueZ and the application side due to a much simpler API.

osso-gwconnect

Removed since identical functionality has been a part of Bluez core since Chinook.

Samba

Samba support to be dropped.

ClinkC

ClinkC deprecated in favour of GUPnP. The following main advantages have been identified to support this transition:

• Designed specifically for Maemo.
• Much simpler design/api compared to ClinkC or any other UPnP library.
• Uses glib's main loop for waiting on sockets rather than launching several threads that adds lots of unneeded complexity and therefore introduces lots of hard-to-kill bugs.

Location framework

Changes tbd.

Multimedia

• Gstreamer OpenMax wrapper on freedesktop.org.
• New GStreamer plugin introduced that wraps openmax-il components under the gstreamer API.
• OpenMax plugins for all the codecs.
• No DSP sink and sources anymore.
• esound replaced by libcanberra.
• Speex introduced.
• GUPnP introduced.

System SW

• initfs isn't used anymore
• Device startup handled by Upstart instead of sysvinit. Location and format of init scripts differ.
• OHM introduced as a policy framework mainly for audio in addition to dsme and mce components, which are responsible for device state and mode control.
• Profile API : A new client library (libprofile) and daemon (profiled) introduced for accessing profile settings.
• Alarm API's updated: The number and functionality of API interface functions remains roughly the same as before. The usage (parameters passed) and underlying transfer protocol (dbus messages) are changed substantially.
• BusyBox updated to 1.10.2 (or newer?).

SDK

• GCC updated to 4.x. Stricter checks for C and C++ code.

RTCom

• Farsight API break: Farsight upgraded/re-written to farsight2.
• Telepathy: libtelepathy outdated. Use telepathy-glib instead.
• Evolution-data-server dropped.
• libgalago and galago-daemon dropped.

Window manager

Window manager upgraded to matchbox-window-manager-2
