The MorphOS development team is proud to announce the May 2026 release of the MorphOS Software Development Kit!

This SDK release delivers a major modernization update for the MorphOS development environment, featuring GCC 15.2.0, Python 3.14.4 with pip and virtual environment support, updated HTML documentation, and extensive updates across the toolchain and bundled utilities. Numerous core development components have been refreshed, including binutils 2.45.1, git 2.54.0, OpenSSL 4.0.0, OpenSSH 10.2p1, ffmpeg 4.4.7, perl 5.42.2, cmake 3.18.6, autoconf 2.73, automake 1.18, and many others.

One of the most important changes in this release is the migration of both ixemul and libnix to 64-bit time_t, off_t and fpos_t types, enabling proper support for dates past 2038 and large files throughout the SDK and newly compiled applications. Due to these ABI changes, developers are strongly encouraged to fully rebuild all existing libraries and object files. This release also includes many stability and compatibility improvements, including significant pdksh rework.

Our new SDK can be found in our files section. As usual, a separate source package is available for download as well.
