Cardiff have terminated the contract of midfielder Guido Burgstaller by mutual consent.
Andy Halliday has turned his loan at Bradford City into a permanent move from Middlesbrough.
Wales age-grade boss Brian Flynn will not be offered a new contract when his current deal runs out at the end of next month, the Football Association of Wales have confirmed.
The former Wales midfielder has held his post since being appointed by John Toshack in 2004, and has gained a reputation for helping develop young talent after nurturing the likes of Gareth Bale, Aaron Ramsey and Joe Allen.
The 56-year-old former Wrexham and Swansea manager twice guided Wales Under-21s to the brink of qualification for the European Championship finals, and racked up impressive victories over France and Italy along the way.
His work at age-grade level was rewarded when he took over as caretaker coach of the senior national side following Toshack's resignation in August 2010, but back-to-back defeats in his two games in charge against Bulgaria and Switzerland led to him missing out on the full-time job to the late Gary Speed.
Flynn also oversaw the Under-19 and Under-17 sides but he will leave his role when his deal expires.
An FAW statement read: "The Football Association of Wales can confirm that Brian Flynn will not be continuing in his role as the Wales Intermediate manager at the end of his present contract on May 30th, 2012.
"The Association would like to thank Brian and acknowledge the tremendous work and effort he has undertaken on behalf of Welsh football over the years.
"He played a huge and important role in the development of the likes of Gareth Bale, Aaron Ramsey, Joe Allen and Wayne Hennessey.
"On a couple of occasions his talented squads narrowly failed to qualify for the final stages of tournaments.
"We wish him every success in the future."
Wales Under-21s currently lie second in their qualification group for the 2013 European Championship, but will have a new man in charge ahead of their vital final two fixtures against Armenia and the Czech Republic later this year.
