* '''28 July 2016:''' The SpUpNIC optics fogged up due to a massive condensation event in the 74". A temporary dry nitrogen purge was introduced into the instrument to drive out the moisture - fortunately no real harm was done.
* '''1 June 2016:''' Disabled the input field and ''Go'' button for changing the grating angle in the instrument control GUI (to accompany the hardware changes described below). Please contact the standby electronics technician if you wish to change either the grating angle or the grating.
* '''26 May 2016:''' A mechanical brake was installed on the grating mechanism to eliminate play in the system (this will be replaced with an electro-mechanical solution to be developed over the coming months).
