Corey O'Keeffe is being released after four years as a professional at Blues.
The attacking midfielder, who can also fill in at right-back, made his First Team debut at Newcastle United in December 2016 and had a subsequent loan spell at Solihull Moors.
This season he was with Macclesfield Town on loan and made 31 appearances for the Silkmen in League Two, which has now ended.
Wideman Olly McCoy is not being retained by Blues.
McCoy began the season on loan at Yeovil Town and then went to Wealdstone temporarily.
McCoy, who had been catching the eye at Beaconsfield, then joined Blues at the beginning of 2017 after a successful trial period. He went on to become a vital member of the Under-23s side.
Defender Ben Forrest, who signed a year's professional contract last summer, is to be released.
Forrest can play at centre-half or right-back and made 13 appearances for the Under-23s this season.
Wingers George Baker and Rhys Hilton are also departing the Club.
Baker joined Blues Academy in 2010 and signed professional last summer.
Hilton rejoined Blues as a professional in September after the Club originally delayed a decision on offering a deal as he had missed a large chunk of his scholarship due to an ankle injury. He went on loan to Redditch United this season.
In the goalkeeper department, Blues have decided to release Michael Luyambula, Adam Siviter and Jake Weaver.
Luyambula signed from Borussia Dortmund in the summer of 2018 and has had loan spells at Hungerford Town and Crawley Town. He went to AFC Telford in January on loan.
Siviter was between the sticks for the Blues side that reached the FA Youth Cup Semi-Finals in 2018.
The option on his professional contract was taken up last year after he spent a spell at Stafford Rangers on loan. Siviter has been on loan to Hungerford Town this season.
Weaver came through Blues Academy from the age of 12.
He was on the bench for the First Team in the opening and final game of the 2018/19 season.
Weaver has had various loan spells away from the Club, including stints at Kidderminster Harriers, Hednesford Town and this season Leamington.
The Club would like to wish all the players every success in the future and we thank them for their efforts during their time with us.
