Goalkeeper Roddy McKenzie has agreed a new two-year contract with Livingston, while midfielder Scott McLaughlin has been given a stay of execution.

But Livi have confirmed that goalkeeper Colin Meldrum, midfielder Craig Easton and forwards Colin McMenamin and Derek Lilley have been released.
McLaughlin had been on loan with Second Division Morton this season and was expected to make the move permanent.
But new manager Paul Lambert has told the 21-year-old he wants him to stay.
Morton had been poised to offer McLaughlin a full-time contract as they had been told that he was not wanted under previous manager Richard Gough.
But he will now remain with Livi for at least another year.
However, Morton still expect to sign Lilley, who left Cappielow for Leeds United for £500,000 in 1999, on a three-year contract.
The 31-year-old, who also had a spell with Oxford United, joined Livi from Dundee United in 2003 but scored only three times this season.
Easton had also been a first-team regular under Gough since his arrival from Tannadice in July.
Former Kilmarnock goalkeeper Meldrum has made only five appearances for Livi since joining at the same time, while former Newcastle United trainee McMenamin has been largely used as a substitute.
Former Aston Villa and Southampton midfielder Hassan Kachloul is also expected to depart Livi after helping them avoid relegation in his short spell with the club.
But chief executive Vivien Kyles stresses that talks are continuing about the retention of several players.
"We are negotiating with several players who we wish to keep as part of the first-team squad as Livingston strives to improve its league position next season," she told the club's website.
"We also expect to sign new players in good time for pre-season training and the start of the new campaign."
