 * Moved the repository to [Github](https://github.com/areaDetector/ADAndor).
 * Re-organized the directory structure to separate the driver library from the example IOC application.
 
+R2-1
+----
+* Added support for the Shamrock spectrographs.  
+  This supports control of grating selection, center wavelength, and slit sizes.
+  It is a separate driver, and is only supported on Windows because Andor does not provide a 
+  Shamrock SDK on Linux.
+* Added support for saving data in Princeton Instruments V3.0 SPE file format with XML footer.
+  This is used to save calibration information from the Shamrock spectrometer.
+  None of the other formats will save calibration information from the SDK, although they do from Solis.
+TODO BEFORE R2-1 RELEASE:
+* Fix problem of crashing when exiting the IOC.
