New boss Gary Waddock has released nine players as he overhauls the squad he inherited from Barry Smith.
Assistant manager Chris Barker, goalkeepers Phil Smith and Dan Thomas, defender Sean McGinty and midfielders Sam Hatton, Jim Stevenson and Dan Walker have left the Recreation Ground.
Central defender Luke Oliver and the versatile Tom Richards have also departed but England C international midfielder Jake Gallagher has signed a new deal.
Prior to swooping for Ross Hannah from the Blues, Barrow boss Paul Cox snapped up centre forward Richie Bennett and 6' 5" centre back Moussa Diarra.
Bennett, 25, arrives from Northwich Victoria, where his form attracted interest from a number of National League and Football League clubs, while Paris-born Diarra, 26, won promotion to the National League South with Hampton & Richmond last season.
Wood manager Luke Garrard has completed the signings of Braintree Town captain Kenny Davis and winger Bruno Andrade from Woking.
Central midfielder Davis was integral to Braintree's third-placed finish last season and featured in over 200 games for the Iron while Portuguese wideman Andrade, whose former clubs include Queens Park Rangers, Aldershot Town and Wycome Wandrers, turned down a new deal at Woking.
Meanwhile, keeper James Russell has moved to St Albans City for a nominal fee and Sam Cox, who made 145 appearances for the club in two spells, has been released.
The Iron have appointed former Welling United boss Jamie Day as their new manager after Danny Cowley departed for Lincoln City.
Day managed Welling for five years before switching to Ebbsfleet United and then becoming assistant to Ady Pennock at Forest Green Rovers.
He is now in talks with the squad regarding next season although captain Kenny Davies has moved to Boreham Wood, Jordan Cox has signed for Maidenhead United and Sean Marks has decided to leave the club in search of more regular starts.
Ravens boss Neil Smith is delighted winger Louis Dennis has signed a new deal with the club, who will move to training three days a week from next season.
Smith said: “It’s fantastic news that Louis Dennis has committed his future to the club. Louis was a big loss when he got injured, his form at the start of season was brilliant and I can’t wait for him to return pre-season.
“I am really keen for us to improve on this season. Training three days a week will play a big part in how we can progress and we’ve made it clear to the players our requirements for next season. This may mean a few personnel changes due to players other commitments but this will become clearer in the coming weeks.”
Dagenham & Redbridge
Following relegation from the Football League, John Still has released no less than 11 players with Jack Connors, Ashley Chambers, Clevid Dikamona, Ian Gayle, Ashley Hemmings, Zavon Hines, Justin Hoyte, Liam O’Brien, Josh Passley, Matt Richards and Ade Yusuff moving on while the Daggers have sold midfielder Jodi Jones to Coventry City, where he finished last season on loan, for an undisclosed fee.
Striker Stefan Payne has signed a two-year deal with League One side Barnsley after his contract expired. The 24-year-old signed for Whites in June 2014 from AFC Hornchurch and was the club's top scorer in both of his seasons at the club.
Chairman Jim Parmenter said: "Stefan joined us from Hornchurch a couple of years ago and has since developed into a fine player, who has contributed a lot to what we have achieved in the last two seasons."
The Spitfires have signed former Luton Town midfielder Jake Howells and ex-Forest Green Rovers captain David Pipe.
England C cap Howells, 25, has penned a two-year deal after leaving Kenilworth Road while Pipe arrives on a 12-month contract.
Experienced midfielder Ben Strevens has agreed a new deal but full-back Dan Harding has been transfer-listed and Lee Cook, Josh Payne, Lewis Noice, Paul Reid, Kaid Mohamed, Jack Midson, Will Evans and Matt Fanimo have been released.
Central defender Jamie Turley has left the club too, turning down a new contract to sign for League Two side Newport County.
Forest Green Rovers
Rovers have agreed a new one-year deal with injured midfielder Sam Wedgbury, who suffered an anterior cruciate ligament injury during the penultimate game of the regular season, ruling him out for the next nine months.
New manager Mark Cooper has released David Pipe, James Jennings, Clovis Kamdjo, Delano Sam-Yorke, Brett Williams, Lenny Pidgeley and Dale Eve but exercised the option of an extra year on the contracts of Elliott Frear, Charlie Clough, Kurtis Guthrie and Rob Sinclair.
Neil Aspin has wasted no time in assembling his squad for 2016-17, bringing in six players already.
The Gateshead boss has signed winger Wes York and defenders Manny Smith and Jamal Fyfield from Wrexham, defender Liam Hogan from Tranmere Rovers, ex-Macclesfield Town forward Reece Styche and experienced midfielder Anthony Sweeney.
Former Hartlepool United man Sweeney arrives after leaving Carlisle United.
Aspin said: He’s made a lot of appearances and scored a lot of goals from midfield. I feel we’ve been lacking that type of player at the club.
“We had a lot of midfielders at the club last year who were all very similar, but we didn’t really have one who was more of a leader in that department, and more box-to-box."
The Lions have agreed new deals with six members of last season's squad with midfielder Will Hatfield, centre back Rob Atkinson, forward Adam Boyes, keeper Dan Atkinson, striker Oli Johnson and defender Danny Lowe signing on.
Leaving the club are Ryan Toulson, Ben Parker, Gavin Rothery, Danny Hall, Liam Dickinson, Nicky Boshell, Oliver Norburn and James Hurst.
New manager Danny Cowley has confirmed his retained list for 2016-17 with Nat Brown, Tony Diagne, Aidan Grant, Matt Sparrow and Liam Hearn, who has signed for Ilkeston, being released.
