GIMP developers have released the latest stable build on the FTP servers. An official announcement is yet to be made.
This is an important release as it finally brings the single window mode to the app which was one of the most desired functionality by the users.
The app also now features an improved text support tool in addition to support for group layers.
Remains to be seen if this release can bring more users to the app now that it has added most of the user demanded functionalities.
