Hello,
So, Libabigail 2.1 has been released.
You can download it at http://mirrors.kernel.org/sourceware/libabigail/libabigail-2.1.tar.gz.
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
https://sourceware.org/libabigail/apidoc. The tools are documented
online as well at https://sourceware.org/libabigail/manual/libabigail-tools.html.
With this release, Libabigail now supports the Compact C Type format,
(a.k.a CTF[1]) alongside the DWARF debug info format.
Another highlight of the release is the support the for Linux kernel
symbol namespaces.
Of course, this release also contains a lot of bug fixes, as usual.
