* '''5 August 2016:''' The cryostat lost vacuum and warmed up. We're not sure what caused this, but suspect that the cryostat valve had not been closed tightly enough and so the vacuum gradually degraded. Leak-testing revealed nothing so we pumped the cryostat over night and the observers were back on-sky a night later.
* '''30 July 2016:''' A new version of the Quick-Look GUI has been installed and seems to be working well, please report any issues to Lisa Crause (lisa_at_saao.ac.za) and David Gilbank (gilbank_at_saao.ac.za).
* '''28 July 2016:''' The SpUpNIC optics fogged up due to a massive condensation event in the 1.9-m dome. 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.
