+* Fri Jan 23 2026  Jakub Martisko <jamartis@redhat.com> - 4.9-5
+- lib/dfa.c: Increase the maximum size of the transitions table
+- After changes introduced between sed 4.2 and 4.4, some regexps
+  started to hit the table size limits. This lead to repeated deletion
+  and rebuilding of the table, leading to massive performance drops.
+  While the core issue is still present, this change should at least
+  help by moving the threshold of the regexp complexity that triggers the 
+  table rebuilds.
+- Resolves: RHEL-144027
+
+* Fri Apr 18 2025 David Abdurachmanov <davidlt@rivosinc.com> - 4.9-4
+- Properly check valgrind arches (fixes riscv64 build)
+  Resolves: RHEL-87803

 * Tue Oct 29 2024 Troy Dawson <tdawson@redhat.com> - 4.9-3
 - Bump release for October 2024 mass rebuild:
