The following non-security bugs were fixed:
- Fix conditional for selecting gcc-13 Fixes: 51dacec21eb1 ('Use gcc-13 for build on SLE16 (jsc#PED-10028).')
- Fix reference in 'net_sched: sch_sfq: use a temporary work area for validating configuration' (bsc#1242504)
- MyBS: Correctly generate build flags for non-multibuild package limit (bsc# 1244241) Fixes: 0999112774fc ('MyBS: Use buildflags to set which package to build')
- MyBS: Do not build kernel-obs-qa with limit_packages Fixes: 58e3f8c34b2b ('bs-upload-kernel: Pass limit_packages also on multibuild')
- MyBS: Simplify qa_expr generation Start with a 0 which makes the expression valid even if there are no QA repositories (currently does not happen). Then separator is always needed.
- Require zstd in kernel-default-devel when module compression is zstd To use ksym-provides tool modules need to be uncompressed. Without zstd at least kernel-default-base does not have provides. Link: https://github.com/openSUSE/rpm-config-SUSE/pull/82
