[maemo-developers] New PySide and QtMobility bindings for Maemo!

[From: Luciano Wolf]

The PySide team is happy to announce new binary packages for PySide
and QtMobility bindings - Maemo version. This release is built against
the PR1.3 SDK and fully supports the new features in Qt 4.7!

There were some package names change to follow the new debian scheme
adopted by the desktop version. Any package depending on
pyside-qt4-<module> should depend on python-pyside.<module> from now
on. The same rule applies to QtMobility packages. They were changed
from pyside-mobility-<module> to python-qtmobility.<module>.

To avoid old application from breaking, transitional metapackages were
also provided.

The packages have already been uploaded to extras-devel. To begin Qt
development on Python for N900, just install the python-pyside /
python-qtmobility metapackages and start rocking!


About PySide
============

PySide is the Nokia-sponsored Python Qt bindings project, providing
access to Qt 4.7 framework, as well as to generator tools for rapidly
generating bindings for any Qt-based libraries.

The PySide project is developed in the open, with all facilities you'd
expect from any modern OSS project such as all code in a git
repository[2], an open Bugzilla[3] for reporting bugs, and an open
design process[4]. We welcome any contribution without requiring a
transfer of copyright.

Major changes since 0.4.1
=========================

The current focus in the development is to stabilize the bindings in
anticipation of the 1.0 release. Hence, PySide 0.4.2 is mainly a
bugfix release: in total, 49 bugs have been resolved!

In addition to the bugfixes, Qt meta-object properties are now
properly supported. See PSEP 103 [5] for details.

Note to packagers and binding developers
========================================

Even though this release is ABI-compatible with the previous one, we
recommend you to rebuild any binding packages generated with Shiboken
with the latest toolchain nevertheless. Due to our binding generation
scheme, the binding code is generated at build time using the
toolchain. Therefore, while the existing bindings continue to work,
the numerous bugfixes and improvements in the toolchain do not get
propagated to the bindings without a rebuild.

Acknowledgements
================

We'd like to thank our community members for all the assistance and
participation. This time, the special mention goes to Roman Lacko for
taking the thankless task of maintaining the Windows packages of
PySide!
