28-year old defender Aaron Brown, has left the club after signing his release forms.
The former Tamworth, Reading and Yeovil Town centre half originally joined the club under Kevin Dillon back in 2010 and went on to help the club reach the play off finals.
After the Shots failed to progress, he opted to join Leyton Orient during the following summer and also had a loan spell at Stockport County before returning last summer when he made a further 13 appearances.
In total he represented the club on 27 occasions and scored one goal, however his last start was back in November 2011 and he had fallen out of favour ever since.
