Libabigail 2.2 has been released.

You can download it at

Libabigail is a library which aims at constructing, manipulating,
serializing and de-serializing ABI-relevant artifacts.

It also comes with a set of associated command line tools to compare
the interfaces of ELF binaries resulting from the compilation of C or
C++ programs.

Typical use cases of libabigail tools include detecting ABI
incompatible changes across several releases of shared libraries or
incompatible changes in the interface between a Linux kernel and its
modules, for instance.

Users can of course write their own tools using the library.

The library comes with extensive API documentation available online at  The tools are documented
online as well at
