Linux Upstream Tracker

API/ABI changes analysis for C/C++ libraries

"This service is intended for operating system maintainers to help in updating libraries and for software developers interested in ensuring backward compatibility of the API"

The service is powered by Andrey Ponomarenko's QA solutions:
  • ABI Compliance Checker - a tool for checking backward
    binary compatibility of a C/C++ library API
  • API Sanity Checker - an automatic generator of basic
    unit tests for a C/C++ library API
  • PkgDiff - a tool for visualizing changes in software packages
Available resources:
  • Today news
  • View history
  • Overall statistics of ABI breaks
  • Tracker for Java libraries
  • ABI tracker for Linux kernel (new!)
