Hello Thiago,
I've removed most of the false positives mentioned in the review from the report: http://abi-laboratory.pro/tracker/timeline/qt/
There are several remaining issues in the report. So I have some questions:
- Is class QPlatformScreen private and all related changes should be removed from the report? (http://abi-laboratory.pro/tracker/compat_report/qt/5.5.1/5.6.0-beta/8f965/abi_compat_report.html)
- Should I hide DesignerSupport class changes? (http://abi-laboratory.pro/tracker/compat_report/qt/5.5.1/5.6.0-beta/7404d/abi_compat_report.html)
- Whats about xdg_* changes in the libQt5WaylandClient.so? (http://abi-laboratory.pro/tracker/compat_report/qt/5.5.1/5.6.0-beta/59c65/abi_compat_report.html)
Thank you.
