AT-SPI2 0.1.6 is now available for download at:

http://download.gnome.org/sources/pyatspi/0.1/
http://download.gnome.org/sources/at-spi2-core/0.1/
http://download.gnome.org/sources/at-spi2-atk/0.1/

Notes
=====

A list of work required before the a full release can be found at:

http://live.gnome.org/Accessibility/BonoboDeprecation

This release is intended to be installed on a system where the CORBA
version of at-spi is already present. Gtk and python modules will be
re-located to non-standard directories on install so as not to conflict
with the AT-SPI CORBA modules. To disable this re-location configure
with the '--disable-relocate' option.

What's changed in AT-SPI2 0.1.6
===============================

Pyatspi:
          * Fix orca performance issues & properly update the cache.

          * Enable re-entrancy.

          * Make AT-SPI Corba the default install and allow for
            re-location of the pyatspi library.

Core:
          * Temporarily disable install of the accessibility bus.

          * Make the registry implement the accessible interface and
            add a socket interface for adding children to its 
            accessible object.

Atk:
          * Plug/socket fixes, and remove conditional
            Always enable plug/socket code.  Bump atk requirement 
            to 1.29.3 accordingly.
            Fix cases where we were omitting the parent of a plug 
            if it was unknown.

          * The StreamableContent interface is not currently supported.
            Stop indicating that it is in the list of interfaces.

          * Modify the paths scheme.
            The null path now signifies no object. A new root path
            has been added representing the root accessible for a
            given connection.

          * Change the keystroke delivery method re-entrancy from
            looping over the bus to entering a g_main_loop.

          * Increase the lease time to rectify errors seen during orca  
            testing.

          * Make AT-SPI Corba the default install. Relocate AT-SPI2 by
            default.

What is AT-SPI2
===============

AT-SPI2 is a D-Bus based accessibility framework. It defines a D-Bus
protocol for providing and accessing application accessibility
information. The project includes a library for bridging the D-Bus
protocol to the ATK API, allowing Gtk based applications to be made
accessible. It also contains a client (AT) side library in Python.

Where can I get more information about AT-SPI2
==============================================

The project wiki is available at:

http://www.linuxfoundation.org/en/Accessibility/ATK/AT-SPI/AT-SPI_on_D-Bus

A page detailing the project plan can be found at:

http://live.gnome.org/Accessibility/BonoboDeprecation

How can I contribute to AT-SPI2?
================================

We are actively seeking contributors to help us make this the standard
a11y framework for Gnome. We need help testing with Gnome accessibility
technologies, and are especially looking for someone to create client
bindings in 'C' that meet the cspi API.

Hi, 

Mousetweaks is an assistive tool that uses at-spi. The patch to migrate mousetweaks to at-spi2 is ready,
but currently it does not make sense to apply it because of the following at-spi2 bug:
http://bugs.freedesktop.org/show_bug.cgi?id=25963 

The object of this email is the following: assuming that the bug gets fixed in time, should we migrate
mousetweaks before the release of GNOME 2.30 or wait for the next development cycle? 

In fact, once mousetweaks has been migrated to at-spi2, it will not work anymore with the old at-spi, making
it useless on system that do not ship the new at-spi2.

Cheers, 

Francesco. 

Hi Francesco:

Thanks for your work!

Would it be possible to add checks to the code to make it either conditionally compile/link for CORBA or
D-Bus, or link against both and have it choose at runtime?

I see in xml/org.freedesktop.atspi.DeviceEventController.xml:

  The best support for pre-emptive global keyboard listeners is provided
  on platforms whose Xserver implementation provides the XEvIE exension.

What should that be changed to?

Cheers,

Patrick

At some point, we need to investigate XInput2 and what it brings to the 
table.  For now, ignore that text and pay no attention to the man 
behind the curtain.  The DeviceEventController should behave properly 
independent of what underlying method (e.g., GTK hooks, XEvIE, XInput2) 
is used.  Of course, there are still some issues to be worked out with 
device event handling in AT-SPI/D-Bus -- it's still a work in progress.

The Libre Software Meeting (LSM or RMLL in French for Rencontres
Mondiales du Logiciel Libre) is conferences cycle about Free
Softawre. LSM is an annual event born in 2000 and since 2003, it
occurs in a different town each year. LSM are free as in beer and as
a speech  No fees, no places limit.

So far, among the various topics (culture, social and solidarity
economy, …) an "accessibility and handicap" topic used to take place.
This year, in addition to being a dedicated topic, the "Accessibility
and Handicap" topic is a transverse topic. It will thus not only
be composed of conferences in its own session (itself composed of
several approaches), but also participation to the other topics.

http://2010.rmll.info/Accessibility-and-handicap-topic.html

Now we just need to fill it! You can not only propose to expose
something among the ideas already proposed or not, or just
give a talk idea, or just a speaker idea, by simply replying to
accessibility <at> listes2010.rmll.info
