+pyqtgraph-0.9.8  2013-11-24
+
+  API / behavior changes:
+    - ViewBox will auto-range when ImageItem changes shape
+    - AxisItem: 
+        - Smarter about deciding which ticks get text
+        - AxisItem.setScale(float) has the usual behavior, but .setScale(None) 
+          is deprecated. Instead use:
+          AxisItem.enableAutoSIPrefix(bool) to enable/disable SI prefix scaling
+    - Removed inf/nan checking from PlotDataItem and PlotCurveItem; improved 
+      performance

+
+Installation Methods
+--------------------
+
+  * To use with a specific project, simply copy the pyqtgraph subdirectory
+      anywhere that is importable from your project
+  * To install system-wide from source distribution:
+        `$ python setup.py install`
+  * For instalation packages, see the website (pyqtgraph.org)
+
+Documentation
+-------------
+
+There are many examples; run `python -m pyqtgraph.examples` for a menu.
+
+Some (incomplete) documentation exists at this time.
+  * Easiest place to get documentation is at <http://www.pyqtgraph.org/documentation>
+  * If you acquired this code as a .tar.gz file from the website, then you can also look in
+      doc/html.
+  * If you acquired this code via GitHub, then you can build the documentation using sphinx.
+      From the documentation directory, run:
+          `$ make html`
+
+Please feel free to pester Luke or post to the forum if you need a specific
