+The following are the changes from calc version 2.11.5t2 to date:
+
+    Fixed a bug, reported by Ernest Bowen <ernie at turing dot
+    une dot edu dot au> that caused command lines to be echoed in
+    interactive mode.  Fixed a bug that sometimes left the terminal
+    in a non-echoing state when calc exited.
+
+    Renamed error codes E_FGETWORD1 and E_FGETWORD2 symbols to
+    E_FGETFIELD1 and E_FGETFIELD2.
+
+    Made a minor format change to the top of the calc man page.
+
+    The findid() function in file.c 2nd argument changed.  The argument
+    is now mostly a writable flag.  This function now finds the file
+    I/O structure for the specified file id, and verifies that
+    it is opened in the required manner (0 for reading or 1 for writing).
+    If the 2nd argument is -1, then no open checks are made at all and
+    NULL is then returned if the id represents a closed file.
+
+    The calc builtin function, fopen(), now allows one to specify
+    opening files in binary modes.  On POSIX / Linux / Un*x-like systems,
+    text file is the same as a binary file and so 'b' to an fopen has
+    no effect and is ignored.  However on systems such as MS Windoz
+    the 'b' / binary mode has meaning.  See 'help fopen' for details.
+
+    On systems (such as MS Windoz), calc will produce a different error
+    message when it attempts to open /dev/tty.  This will condition
+    will occur in things like calc scripts when they switch from ``batch
+    processing'' commands from and want to start interactive mode.
+
+    Regression tests fopen in binary mode in a few places where a
+    difference between text and binary string lengths matter.
+    The intfile calc resource file also uses binary mode.
+
+    Changed the rand() builtin and its related functions srand() and
+    randbit() to use the Subtractive 100 generator instead of the
+    additive 55 generator.  This generator as improved random properties.
+    As a result, of this change, the values produced by rand(),
+    rand() and randbit() are now different.
+
+    Updated regression tests for new rand() and randbit() output.
+
+    Applied a bug fix from Ernest Bowen <ernie at turing dot une dot
+    edu dot au> dealing with one-line "static" declaration like:
+
+    	static a = 1, b;
+
+    Added regression test 8310 to test for the static bug fix.
+
+
 The following are the changes from calc version 2.11.5t0 to date:

    Fixed a compile problem with Linux 2.4 / Debian.  Thanks goes
