*'''10 April 2017:''' G7 replaced with an almost identical new one that does not have fingerprints or scratches! The blaze of the new one is at 5000A, rather than 4600A, since the latter is no longer available from the manufacturer. The 5000A blaze is also a better match for the peak response of this CCD.
* '''30 March 2017:''' New functionality added to the GUI for the rear-of-slit (Lodestar) camera to allow background subtraction. There is now also a slider bar to adjust the brightness of the display, this works best with background subtraction applied.
* '''20-25 January 2017:''' Engineering run during which the cryostat was re-aligned to the rest of the instrument in an attempt to remove what was thought to be coma in the images. Eventually concluded that the faint tails extending redward of arc lines are an optical ghost - a series of reflections thought to arise as light bounces between the CCD and the field-flattener lens that forms the cryostat window. There is no simple fix for this so the effect will just have to be quantified.
* '''21 December 2016:''' Initial documentation for Quick-Look GUI added: https://topswiki.saao.ac.za/index.php/Quick_Look_Tool
