-* Plots made with Array.plot() in a Python script will be shown by default,
-  unless either the filepath (see below) or ax arguments are used. Shown plots
-  will open a window and pause the running script until the window is closed by

 New features
 ^^^^^^^^^^^^
 
-* Array.plot now has an ´animate´ argument to produce animated plots. The
-  argument takes an axis (it also supports several axes but that is rarely
-  useful) and will create an animation, with one image per label of that axis.

   will create an animated bar plot with one frame per year.

+* implemented :py:obj:`Array.plot()` ``show`` argument to display plots
+  directly, without having to use the matplotlib API. This is the new default
+  behavior, unless a ``filepath`` is given.
 
 * implemented a new kind of plot: `heatmap`. It can be used like this:
 
     >>> arr.plot.heatmap()
 
+* implemented :py:obj:`Session.align()` to align all the arrays in several
+  sessions at once. Closes :issue:`501`.
+
 * added a feature (see the :ref:`miscellaneous section <misc>` for details). It works on :ref:`api-axis` and
   :ref:`api-group` objects.

 Fixes
 ^^^^^
 
-* fixed something (closes :issue:`1`).
+* fixed error message when trying to take a subset of an array with an array
+  key which has ndim > 1 and some bad values in the key. The message was also
+  improved (see the issue for details). Closes :issue:`1134`.
+
+* added support for Pandas Series in :py:obj:`asarray()`. This is considered a
+  fix because it kind of worked but silently ignored the index and name of the
+  series (closes :issue:`895`).
+
+* fixed evaluating operations involving X.axis and an array when
+  that operation is only valid in the context of a larger array by delaying
+  the evaluation until the larger array is known (closes :issue:`1129`).
