Andy Kilmartin has signed for recently relegated Portadown.
The Glenavon midfielder agreed a two-year deal to join Niall Currie’s Portadown after his contract with the Lurgan Blues expired. Currie said he was "over the moon" with the signing. Experienced centre-back David Elebert has also left Glenavon.
Ballymena United, meanwhile, have added Carrick full-back Stephen McCullough to their squad.
“We know that the left back position caused us some anxiety this year, and with Stephen McBride forced to retire due to injury and Daniel Wallace recalled back to Linfield from his loan, that leaves us with Adam McCracken and Leroy Millar," boss David Jeffrey told the club's official website.
"Adam is unsure where his academic future is going to take him with university across the water an option, whilst Leroy excelled in that position this season, he sees further up the pitch as the best position for him, but he still gives us an option in defence.
"We've been watching Steven for some time and so we approached things in the right manner by making our intentions clear to Carrick that we wished to speak to him, and subsequently met with him to lay out our plans for the future."
Former Linfield winger Jonny Frazer, who was released from Windsor Park earlier this month, has joined Ards. The 20 year-old has spent time on loan at Warrenpoint and Ballymena United. He featured in just four league games for Linfield last season.
Coleraine have added Aaron Traynor and Stephen O'Donnell. Midfielder Aaron Traynor arrives from Warrenpoint but has significant top level experience, having previously played for Lisburn Distillery, Portadown and Carrick Rangers. O'Donnell is a 24 year-old defender who captained Institute during his five year spell at the club.
Dungannon Swifts have added another former Ballinamallard player to their ranks. Full-back Liam McMenamin joins Rod McAree's panel from Strabane Athletic. He played for the intermediate side for just half a season, arriving in January after his three and a half year spell with the Mallards came to an end.
Meanwhile, Andrew Burns has left Dungannon Swifts "by mutual consent" as the player looks for a new challenge and the club have agreed to accept his request.
Elsewhere, Institute are looking for a new manager after Kevin Deery left the role and Brendan Shannon has taken over as Player / Head Coach at Lurgan Celtic.
Newly promoted Warrenpoint Town have made the most summer signings with SEVEN so far. Sean Mackle and Matty Parker both joined from Portadown, Luke Fisher signed from Glenavon, Alan Blayney came in from Dundela while Darren Murray, Darius Roohi and Seanna Foster all joined Matthew Tipton's ranks as well.
