problematic because the applications
installed by the users need to be reinstalled
manually.

Identified future releases
maemo and the Internet Tablet OS to share
●
wind codenames and version numbers.
● Codenames don't reveal major/minor
releases, release dates or new devices.
● Useful tool to communicate plans to the
maemo community and Nokia partners.
● They follow the alphabet: after B(ora) will
come C, D, E, F...
● Bora and the 3.x series will be followed by
maemo 4.0 Chinook. Then Diablo. Then
Elephanta...

Consolidating API management
Chinook will bring another API break,
●
needed for the alignment with GTK+
upstream (from 2.6 to 2.10).
● Developers can partially test applications
on top of Sardine already.
● Plan to release alpha and beta SDKs to
facilitate porting before Chinook launch.
● From Diablo onwards we aim to keep
backward compatibility in justified API
breaks to grant platform stability.
● We depend from upstream breaks, though.

Hildon goes upstream
User environment designed for mobile
●
devices with a strong focus on usability and
attractive look & feel.
● Originally designed for touchscreen input
with a stylus or thumb.
● First developed for Nokia Internet tablets,
now aiming to support several form factors
as well.
● Built on top of the GNOME Mobile and
Embedded platform.
Quim Gil / LinuxTag / Berlin / 1-june-2007

code in your hands
Hildon goes upstream
Provides a set of libraries, a theme
●
framework, the Hildon desktop, an input
methods framework and UI guidelines to
build applications.
● Plugin interfaces to extend Hildon.
● Language bindings. So far it supports
Python and C++. Other languages under
consideration.
● All components have accessibility support,
especially to allow automatic UI testing with
tools like Dogtail.
