The T2 SDE 21.5 meta-distribution has been released, providing an environment for creating your own distributions, cross-compiling and maintaining package versions up to date. Distributions can be based on Linux, Minix, Hurd, OpenDarwin, Haiku, and OpenBSD. Of the popular distributions built on the basis of the T2 system, Puppy Linux can be noted. The project provides basic bootable iso images (from 382 to 735 MB) with a minimal graphical environment. More than 2000 packages are available for assembly.
The new release adds support for s390x and SuperH architectures, and brings 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 enabling TLB flush parallelism, faster implementation of zstd, reduced shutdown time, and profile-guided optimization (PGO) for builds. Updated component versions include GCC 11, Linux kernel 5.12.4, LLVM/Clang 12, GNOME 40, and recent releases of X.org, Mesa, Firefox, Rust, and KDE.
