+The following are the changes from calc version 2.12.4.6 to date:
+
+    Updated RPM build process to remove use of deprecated flags.
+
+    Applied a number of fixes calc.spec file.
+
+    Changed rpm release to 2.1.
+
+
+The following are the changes from calc version 2.12.4.3 to 2.12.4.5:
 
     Added gvec.cal resource script.
 
-    Added calc-symlink make rulle to setup symlinks from stardard locations
+    Added calc-symlink make rule to setup symlinks from stardard locations
     into a tree specified by a non-empty ${T} makefile variable.  Added
     calc-unsymlink to remove any symlinks that may have been created by
     the calc-symlink rule.
 
+    If is OK for the calc-symlink make rule to pre-remove a symlink.
+
+    Fixed bug was uncovered in calc that caused script failures when calc
+    is called within a while loop in BASH if the while loop is fed from
+    stdin due to calc's redirection/inheritance of stdin and no option
+    to change this behavior.  Thanks gores to David C. Rankin
+    <drankinatty at gmail dot com> for the bug fix and to David Haller
+    <dnh at opensuse dot org> for helping debug this problem.
