I've started to maintain ABI report for the Concurrency Kit here: http://abi-laboratory.pro/tracker/timeline/ck/
This is one of the libraries I maintain at http://abi-laboratory.pro/tracker/
with the aim to improve stability of the Linux ABI (kernel&base libraries for a start).
Hope the report will help Linux maintainers of the shared library to be aware of ABI changes and added/removed binary symbols. Please let me know if you'll find false positives in the report or if some comments should be added to the report.
The source code of the tracker is available here: https://github.com/lvc/abi-tracker
