+* Thu Mar  4 2021 Matthew Miller <mattdm@fedoraproject.org> - 2.12.8.2-1
+- new upstream stable release 
+- the value of exponent expressins which equal zero (like 0^(0) or 0^zero
+  where zero is a variable with value 0) is now 1, just like 0^0
+- Calc shell scripts now need to be called with and -s -f at the end of the
+  shebang #! line.
+- set ARCH_CFLAGS to nothing, because otherwise it will now default to
+  putting -march=native in there, which reduces portability and may conflict
+  with rpm opt flags.
+
 * Tue Jan 26 2021 Fedora Release Engineering <releng@fedoraproject.org> - 2.12.7.2-7
