+- Update to version 1.4.7
+  * Fix incorrect work of set_* where hash function generates
+    full ulong_t hash value
+  * hsh_string_hash generates full 64bit hash value on platforms
+    where sizeof(long) == 8
+  * Improve build and test system
+  * tests/err: minor fix, target "test" should not remove _mkc_*
+    and .o files
+  * Avoid trailing \n in format argument for err_* functions, no
+    need for it any longer
+  * tests/err/errtest.c: fix another compilation failure due to
+    __wur (warning used result)
+  version 1.4.6
+  * Add missing fix (compilation failure) for tests/err/errtest.c
+  version 1.4.5
+  * err_* functions:
+    + Fix segfault caused by "ap" is used twice.  Solution is to
+      va_copy it and use copied "ap" for printing to stderr.
+    + Improve formatting (no empty lines in log files)
+  * err_set_program_name: handle correctly NULL argument
+  * log_mkpath function: avoid use of alloca(3)
+  * hsh_pointer_compare function now follows -1/0/1 logic
+  * Add more tests for log_*, err_*, hsh_* and set_* function
+
+- Fix build with gcc 9.x
+
+- Drop Group tag
+
+- Spec cleanup
