AT-SPI2 0.3.2 Released

release date: 2010-05-24

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.

AT-SPI2 0.3.2 is now available for download at:

This release fixes numerous bugs and should generally be much more usable than prior releases.

What's changed in AT-SPI2 0.3.2

pyatspi Changes

  • Remove double deletion of application from the desktop cache handler. Was causing a mostly harmless exception when an application shut down.
  • Role changes now update the cache.
  • Avoid throwing an exception in getState() if an object no longer exists. This avoids potentially throwing an eception where at-spi-corba may not.
  • Do not use the cache if registry.start() has not been called; allows simple scripts without a main loop to work better. Disable relocation by default.

core changes

  • Make sure that disconnecting applications send their root path in the remove applications signal. This was causing applications to not be removed from the desktop properly.

Atk Changes

  • Some hyperlink fixes.
  • Cache additions are now done in an idle call. This prevents additions from being made when an object may not be fully initialized and prevents Firefox 3.6 from crashing.
  • The cache object has been placed into the org.a11y.atspi namespace. Disabled relocation by default.

How can I contribute to AT-SPI2?

We are actively seeking contributors to help us make this the standard accessibility framework for Gnome. We need help testing with Gnome accessibility technologies, improving performance, and generally tying up loose ends. The above-referenced page contains a list of known issues that should be fixed.
