Tumbleweed Updates From openSUSE People

  • Tools Strace, BusyBox Update in Tumbleweed - openSUSE News

    openSUSE Tumbleweed had a variety of package updates in smaller snapshots throughout this week. A few things being prepared for Tumbleweed is that the Linux Kernel 5.16.1 was scheduled for check in and pre-integration tests for GNU Compiler Collection 12 have been started; the rolling release anticipates a merge of GCC 12 in mid-Spring. The latest Tumbleweed snapshot, 20220117, updated Italian translations for libstorage-ng 4.4.75 and added python-rpm-macros for building the package. Haskell support was dropped in the thrift 0.15.0 package, which is a scalable cross-language service framework for Remote Procedure Call and Inter-Process Communication. No changelogs were provided for the plugins package written in Rust called gstreamer-plugins-rs. The remaining packages in the snapshot were all Python Package Index updates. Among the key PyPI packages to point out is the major version update of python-unicodedata2 14.0.0, which dropped support for End of Life Python 2.7 and 3.5 and added support for Python 3.9, 3.10 and PyPy3. A Tumbleweed arm 20220118 snapshot was release updating the same package listed above.
