 * added official support for Python 3.9 (0.32.3 already supports it even though it was not mentioned).
 
-* added a feature (see the :ref:`miscellaneous section <misc>` for details). It works on :ref:`api-axis` and
-  :ref:`api-group` objects.
+* added :py:obj:`CheckedSession`, :py:obj:`CheckedParameters` and :py:obj:`CheckedArray` objects.
 
-  Here is an example of the new feature:
+  `CheckedSession` is intended to be inherited by user defined classes in which the variables of a model
+  are declared. By declaring variables, users will speed up the development of their models using the auto-completion
+  (the feature in which development tools like PyCharm try to predict the variable or function a user intends
+  to enter after only a few characters have been typed). All user defined classes inheriting from `CheckedSession`
+  will have access to the same methods as `Session` objects.
 
-    >>> arr = ndtest((2, 3))
-    >>> arr
-    a\b  b0  b1  b2
-     a0   0   1   2
-     a1   3   4   5
+  `CheckedParameters` is the same as `CheckedSession` but the declared variables cannot be
+  modified after initialization.
 
-  And it can also be used like this:
+  The special :py:funct:`CheckedArray` type represents an Array object with fixed axes and/or dtype.
 
-    >>> arr = ndtest("a=a0..a2")
-    >>> arr
-    a  a0  a1  a2
-        0   1   2
-
-* added another feature in the editor (closes :editor_issue:`1`).

-  .. note::
-
-     - It works for foo bar !
-     - It does not work for foo baz !
+  Closes :issue:`832`.
