-Version 8.2.0 is released.   This version has a few new operators and streamlined unit tests, as well as the usual bug fixes.
+Version 8.3.0 is released.   This is another incremental release with a few new operators.  I've also been focusing on
+filling in help text for all the units.  Right now there are 172 units that don't have help text.

+## Using rpnChilada
 
 rpnChilada is very easy to use.  It's just like any RPN calculator: Operands go first, then the operators. All examples assume `rpn` is an alias for `python /<path-to-rpn>/rpn.py`.  In interactive mode, you leave off the `rpn`.
 I always create an alias for "python rpn.py" called "rpn".  If you are using the package installed with pip, there are commands in the scripts directories called "rpn" and "rpnChilada" to launch rpnChilada.

+## Built-in Help
+
 rpn has pretty extensive built-in help, although the help files are not complete. However, all operators have at least a brief description, and most are obvious enough to use easily.
 
 Start with `rpn help` for an overview. To dive right in, see `rpn help examples`. In interactive mode, typing `help` will launch help mode. Then, `topics` will print out a list of help topics and `exit` will return to rpn.
 
+## Data Files
+
 The data files are stored in the same location as `rpn.py` in a subdirectory called `rpndata/`.

 ## Release Notes

+Added the 'solve_frobenius' operator and renamed 'denomination_combinations' to
+'count_frobenius'.
+
+Added the 'sequence' and 'tau' operators.
 
 The astronomy operators now don't care which order the arguments are in, except
 for 'angular_separation', which expects the first two arguments to be
