Backward compatibility report
Hello,
I've prepared backward compatibility reports for HttpClient and HttpCore libraries:
http://abi-laboratory.pro/java/tracker/timeline/httpclient/
http://abi-laboratory.pro/java/tracker/timeline/httpcore/
I hope they will help users, maintainers and developers to maintain backward compatibility. The reports are updated daily by the japi-compliance-checker and japi-tracker tools: https://github.com/lvc/japi-compliance-checker
Please let me know if there are some false positives in the report.
Thank you.

Great!
Are you by any chance going to build a Maven plugin for your report
generator? I would love to replace Clirr plugin with something better.

Hello,
Thank you for reporting this bug. Usually the tool checks super-classes and doesn't report removal of overwritten methods. But in this case the super-class is defined in the different jar (httpcore-4.2.5.jar) and therefore it was not taken into account. I'll try to fix the report soon.

Hi Andrey
The reports look pretty awesome.
However, if I am not mistaken removal of overwritten methods from a
subclass should not affect binary compatibility, should it?
http://abi-laboratory.pro/java/tracker/compat_report/httpcore/4.2.5/4.3/55421/bin_compat_report.html#Removed
High severity for these changes sounds a bit too much if you ask me.

It does not make sense to check compatibility between 4.x and 5.x
The 5.0 series deliberately breaks compatibility.
So it uses a different package name and different Maven coordinates.
This allows the jars to co-exist safely on the classpath.
Note: if either the package name is changed, or the Maven coord (GA)
is changed (but not both) then that is an error.
