Qt? 99.99% of the API from Qt 4 (2005) is identical in Qt 6 (ongoing). A few headers were renamed, and a few minor functions, generally stuff you can port in 1 day.
When they released Qt 5 and 6 and decided to switch from Qt Widgets to a new GUI toolkit (QML), they didn't say "umm, just rewrite your whole codebase in QML bro", they kept widgets around in perpetual maintenance mode. This is how you respect your users.
- dvdkon 3y agoI think what Qt does is a good compromise, but there are breaking changes. Complex FLOSS projects spent months or years upgrading from Qt4 to Qt5 and then to Qt6. The exact timeframe is a matter of priorities and available developers, but someone had to put a not insignificant amount of work into porting. A far cry from decades-long ABI compatibility.
