 CHANGES
 =======
 
-6.0.0dev0
----------
 
-A fair bit of code refactoring has gone on so that we might be able to scale the code, get it to be more performant, and more in line with other interpreters.
+New Builtins
+++++++++++++
+
+
+* `Elements`
+
+
+Compatibility
+-------------
+
+* ``*Plot`` does not show messages during the evaluation.
+
+
+
+Internals
+---
+
+* ``eval_abs`` and ``eval_sign`` extracted from ``Abs`` and ``Sign`` and added to ``mathics.eval.arithmetic``.
+* Maximum number of digits allowed in a string set to 7000 and can be adjusted using environment variable
+  ``MATHICS_MAX_STR_DIGITS`` on Python versions that don't adjust automatically (like pyston).
+
+
+Bugs
+----
+
+* Improved support for ``DirectedInfinity`` and ``Indeterminate``.
+* ``Definitions`` is compatible with ``pickle``.
+
+
+Package updates
++++++++++++++++
+
+#. Python 3.11 is now supported
+
+
+6.0.1
+-----
+
+Release to get Pillow 9.2 dependency added for Python 3.7+
+
+Some Pattern-matching code gone over to add type annotations and to start
+documenting its behavior and characteristics. Function
+attributes are now examined and stored at the time of Pattern-object creation
+rather than at evaluation time. This better matches WMA behavior which pulls
+out attribute this even earlier than this.  These changes speed up
+doctest running time by about 7% under Pyston.
+
+Combinatorica version upgraded from 0.9 (circa 1992) to 0.91 (circa 1995) which closer matches the published book.
+
+Random builtin documentation gone over to conform to current documentation style.
+
+6.0.0
+-----
+
+A fair bit of code refactoring has gone on so that we might be able to
+scale the code, get it to be more performant, and more in line with
+other interpreters. There is Greater use of Symbols as opposed to strings.
+
+The builtin Functions have been organized into grouping akin to what is found in WMA.
+This is not just for documentation purposes, but it better modularizes the code and keep
+the modules smaller while suggesting where functions below as we scale.
+
+Image Routines have been gone over and fixed. Basically we use Pillow
+imaging routines and as opposed to home-grown image code.
+
+A number of Built-in functions that were implemented were not accessible for various reasons.
+
+Mathics3 Modules are better integrated into the documentation.
+Existing Mathics3 modules ``pymathics.graph`` and ``pymathics.natlang`` have
+had a major overhaul, although more is needed. And will continue after the 6.0.0 release
+
+We have gradually been rolling in more Python type annotations and
+current Python practices such as using ``isort``, ``black`` and ``flake8``.
+
+Evaluation methods of built-in functions start ``eval_`` not ``apply_``.
 
-Image Routines have been gone over. A number of Built-in functions that were implemented were not accessible for various reasons.

 #. ``boxes_to_`` methods are now optional for ``BoxElement`` subclasses. Most of the code is now moved to the ``mathics.format`` submodule, and implemented in a more scalable way.
 #. ``from_mpmath`` conversion supports a new parameter ``acc`` to set the accuracy of the number.
 #. ``mathics.builtin.inout`` was split in several modules (``inout``, ``messages``, ``layout``, ``makeboxes``) in order to improve the documentation.

-#. Operator name to unicode or ASCII comes from Mathics scanner character tables.
-#. Builtin instance methods that start ``apply`` are considered rule matching and function application; the use of the name ``apply``is deprecated, when ``eval`` is intended.
