KDevelop released KDevelop 5.3 beta 1.
In the release notes they wrote
Support for other platforms
KDevelop is written with portability in mind, and relies on Qt for solving the big part there, so next to the original “unixoid” platforms like Linux distributions and the BSD derivatives, other platforms with Qt coverage are in good reach as wel, if people do the final pushing. So far Microsoft Windows has been another supported platform, and there is some experimental, but maintainer-seeking support for macOS. Some porters of Haiku, the BeOS inspired Open Source operating system, have done porting as well, building on the work done for other Qt-based software. For KDevelop 5.3 the small patch still needed has been applied to KDevelop now, so the Haiku ports recipe for KDevelop no longer needs it.
KDevelop is already in the HaikuDepot, currently still at version 5.2.2. It will be updated to 5.3.0 once the release has happened.
