+New features
+------------
+
+* implemented set_axes() method to replace one, several or all axes of an array (closes :issue:`67`).
+  The method with_axes() is now deprecated (set_axes() must be used instead).
+
+    >>> arr = ndtest((2, 3))
+    >>> arr
+    a\\b | b0 | b1 | b2
+     a0 |  0 |  1 |  2
+     a1 |  3 |  4 |  5
+    >>> row = Axis('row', ['r0', 'r1'])
+    >>> column = Axis('column', ['c0', 'c1', 'c2'])
+
+    Replace one axis (second argument `new_axis` must be provided)
+
+    >>> arr.set_axes(x.a, row)
+    row\\b | b0 | b1 | b2
+       r0 |  0 |  1 |  2
+       r1 |  3 |  4 |  5
+
+    Replace several axes (keywords, list of tuple or dictionary)
+
+    >>> arr.set_axes(a=row, b=column)
+    or
+    >>> arr.set_axes([(x.a, row), (x.b, column)])
+    or
+    >>> arr.set_axes({x.a: row, x.b: column})
+    row\\column | c0 | c1 | c2
+            r0 |  0 |  1 |  2
+            r1 |  3 |  4 |  5
+
+    Replace all axes (list of axes or AxisCollection)
+
+    >>> arr.set_axes([row, column])
+    row\\column | c0 | c1 | c2
+            r0 |  0 |  1 |  2
+            r1 |  3 |  4 |  5
+    >>> arr2 = ndrange([row, column])
+    >>> arr.set_axes(arr2.axes)
+    row\\column | c0 | c1 | c2
+            r0 |  0 |  1 |  2
+            r1 |  3 |  4 |  5
+
+* implemented from_string() method to create an array from a string:
+
+    >>> from_string('''age,nat\\sex, M, F
+    ...                0,  BE,       0, 1
+    ...                0,  FO,       2, 3
+    ...                1,  BE,       4, 5
+    ...                1,  FO,       6, 7''')
+    age | nat\sex | M | F
+      0 |      BE | 0 | 1
+      0 |      FO | 2 | 3
+      1 |      BE | 4 | 5
+      1 |      FO | 6 | 7
+
+* allowed to use a regular expression in split_axis method (closes :issue:`106`):
+
+    >>> combined = ndrange('a_b = a0b0..a1b2')
+    >>> combined
+        a_b | a0b0 | a0b1 | a0b2 | a1b0 | a1b1 | a1b2
+            |    0 |    1 |    2 |    3 |    4 |    5
+    >>> combined.split_axis(x.a_b, regex='(\w{2})(\w{2})')
+        a\\b | b0 | b1 | b2
+         a0 |  0 |  1 |  2
+         a1 |  3 |  4 |
+
+* allowed the syntax axis[groups]:
+
+    >>> groups = year[2001:2004], year[2008,2009]
+    >>> groups
+    (year[2001:2004], year[2008, 2009])
+    >>> x.time[groups]
+    (x.time[2001:2004], x.time[2008, 2009])
+
+Miscellaneous improvements
+--------------------------
+
+* added installation instructions (closes :issue:`101`).
+
+* viewer : make shortcuts work even when the focus is not on the array editor widget
+  (ie it is on the array list, or on the interactive console) (closes :issue:`102`).
+
+* allowed matrix multiplication (@ operator) between arrays with dimension != 2 (closes :issue:`122`).
+
+* viewer : automatically display plots done in the viewer console in a separate window
+  (unless "%matplotlib inline" is used). Plots can be done via the array widget
+  (using shortcut CTRL+P or right click) or from the console:
+
+    >>> arr = ndtest((3, 3))
+    >>> arr.plot()
+
+  Now both methods generate a plot in separate window.
+
+* improved LArray.plot to get nicer plots by default.
+  The axes are transposed compared to what they used to, because the last axis is often used for time series.
+  Also it considers a 1D array like a single series, not N series of 1 point.
+
+* Axis.group is now deprecated (Syntax "age[10:19] >> 'teens'" must be used instead)
+  (closes :issue:`148`).
+
+Fixes
+-----
+
+* viewer: allow changing the number of displayed digits even for integer arrays as that makes sense when using
+  scientific notation (closes :issue:`100`).
+
+* viewer : fixed opening a viewer via view() edit() or compare() from within the viewer
+  (closes :issue:`109`)
+
+* viewer : fixed compare() colors when arrays have values which are very close but not exactly equal
+  (closes :issue:`123`)
+
+* viewer : fixed legend when plotting arbitrary rows (it always displayed the labels of the first rows)
+  (closes :issue:`136`).
+
+* fixed posargsort labels (closes :issue:`137`).
+
+* viewer : fixed xticklabels when zooming on a plot (closes :issue:`143`)
