+BTF encoder:

+- The parallel reproducible BTF generation done using the new DWARF loader

+* Wed Jan 15 2025 Arnaldo Carvalho de Melo <acme@redhat.com> - 1.29-1
+- Multithreading is now in the DWARF loader using a jobs queue and a pool of worker threads.
+- The BTF encoding now is always reproducible, and as fast/faster than before.
+- The memory consumption is reduced.
+- Support for multiple BTF_DECL_TAGs pointing to same tag.
+- Verify that pfunct prints btf_decl_tags read from BTF.
+- Don't print functions twice when using 'pfunct -f function_name'.
