 Syntax changes
 ^^^^^^^^^^^^^^
 
-* deprecated :py:obj:`Session.add()`. Please use :py:obj:`Session.update()` instead (closes :issue:`999`).
+* made :py:obj:`Array.append()` work for the cases previously covered by ``Array.extend()`` (when the appended value
+  already has the axis being extended) and deprecated ``Array.extend()`` (closes :issue:`887`).
 
-* deprecated passing individual session elements as non-keyword arguments to :py:obj:`Session()`.
-  This means that, for example, ``Session(axis1, axis2, array1=array1)`` should be rewritten as
-  ``Session(axis1name=axis1, axis2name=axis2, array1=array1)`` instead. Closes :issue:`1024`.
+* renamed ``Array.sort_axes()`` to :py:obj:`Array.sort_labels()` (closes :issue:`861`).
 
 * renamed :py:obj:`Array.percentile()` and :py:obj:`Array.percentile_by()` `interpolation` argument
   to `method` to follow numpy and thus support additional "interpolation" methods.

-
 * deprecated the ability to target a label in an aggregated array using the group that created it.
   The aggregated array label should be used instead. This is a seldom used feature which is complex
   to keep working and has a significant performance cost in some cases, even when the feature is not used

 Miscellaneous improvements

-* made all I/O functions/methods/constructors to accept either a string or a pathlib.Path object
+* made all I/O functions/methods/constructors accept pathlib.Path objects in addition to strings
   for all arguments representing a path (closes :issue:`896`).
 
 * added type hints for all remaining functions and methods which improves autocompletion in editors (such as PyCharm).

 * made :py:obj:`ipfp()` faster (the smaller the array, the larger the improvement)
   For example, for small arrays it is several times faster than before, for 1000x1000 arrays it is about 30% faster.
 
-* made operations between two Arrays with the same axes much faster.
+* made arithmetic operations between two Arrays with the same axes much faster.
 
 * made Array[] faster in the usual/simple cases.
