AT-SPI2 Released

release date: 2011-02-01

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-SPI5 is now available for download at:

Note: at-spi2-core 1.91.6 contained a crash introduced with a last-minute API addition, so there is a with a fix for that and another issue.
