Brendan Rodgers hopes selling striker Andy Carroll to West Ham will help kick-start his squad strengthening at Liverpool.
Liverpool manager Brendan Rodgers fully expects star striker Luis Suarez to be at the club next season.
The club announced on their website that the former Arsenal player would not be offered a new contract.
Stack made 61 appearances at Easter Road but injury affected all of his three seasons.
The 30-year-old was first choice for most of Pat Fenlon's time in charge before his season was ended by a torn thigh muscle sustained in the William Hill Scottish cup semi-final win over Aberdeen last month.
Stack's exit was confirmed 24 hours after Hibs released club captain Ian Murray and young players Scott Taggart and Sean Welsh.
Loan players George Francomb, Matt Doherty, Roy O'Donovan, Tom Soares, Richie Towell, Leigh Griffiths and James McPake also left the club after the 5-1 cup final thrashing by Hearts.
Goalkeeper Mark Brown and striker Garry O'Connor are also out of contract.Despite being deemed surplus to requirements at the end of his testimonial season, Murray today called for Fenlon to be given time to overhaul the club.
The 31-year-old, who was restricted to four appearances since Fenlon came in as he battled a hip problem, told STV: "You can look back to four or five years ago under Mixu Paatelainen as manager who was finishing sixth and it still wasn't good enough.
"We have to decide now, pretty quickly, what's acceptable and what's not.
"I think the manager was to given a bit of time to make his mark on the squad.
"He is obviously wanting to clear people out and get people in.
"It's easy for me to say now, but there were other managers there that perhaps deserved more time and didn't get it.
"Football can be a cruel game, you live and die by results and if results don't go well next season, what do you do? Do you keeping sacking managers? I don't know, I'm not qualified to make that decision.
"I look back at us finishing sixth and it still wasn't good enough, then fourth (under John Hughes) and it wasn't good enough. Then Colin Calderwood got quite a short reign at the club.
"Now we've finished 11th and been beaten 5-1 in a final. It just shows the people who want change all the time that it's not always a good thing."
