The T2 SDE 21.5 meta-distribution has been released, providing an environment for creating custom distributions, cross-compilation, and maintaining up-to-date package versions. Distributions can be built based on Linux, Minix, Hurd, OpenDarwin, Haiku, and OpenBSD. Among the popular distributions built on the T2 system is Puppy Linux. The project offers basic bootable ISO images (from 382 to 735 MB) with a minimal graphical environment. More than 2000 packages are available for building.
The new release adds support for s390x and SuperH architectures, bringing the total number of supported hardware architectures to 18 (alpha, arm, arm64, hppa, ia64, m68k, mips64, mipsel, ppc, ppc64-32, ppc64le, riscv, riscv64, s390x, sparc64, superh, x86, and x86-64). Significant optimizations have been made, including the utilization of TLB flushing parallelism, a faster implementation of zstd, reduced shutdown time, and the application of code profiling-based optimizations (PGO - Profile-guided optimization) during builds. Updated component versions include GCC 11, Linux kernel 5.12.4, LLVM/Clang 12, GNOME 40, as well as recent releases of X.org, Mesa, Firefox, Rust, and KDE.
