+* Mon Jun 12 2023 Eugene Syromiatnikov <esyr@redhat.com> - 1.0-13
+- Handle symvers.xz in kabi.attr (#2209253).
+- Fix indirect __crc_* sumbols parsing in find-provides.ksyms
+  and find-requires.ksyms to avoid matching multiple sections
+  producing bogus duplicate provides for kmods that have both __kcrctab
+  and __kcrctab_gpl sections (#2115811, #2178935).
+- Call "readelf -R" on a correct section in find-requires.ksyms.
+- Rewrite section data extraction in find-provides.ksyms and find-requires.ksyms
+  to avoid garbage at the end of extracted sections, causing unnecessary awk
+  complaints (#2115811).
+- Perform section parsing inside the awk script in find-provides.ksyms
+  and find-requires.ksyms to avoid hitting command line argument limit
+  when handling large .rodata sections (#2178935).
+
 * Tue Jan 31 2023 Eugene Syromiatnikov <esyr@redhat.com> - 1.0-12
 - Support storing of __crc_* symbols in sections other than .rodata.
 - Resolves: #2135047
