> When do you release the next version of GIMP? > > We release both updates to the current stable version and development versions. > > We cut new updates of the stable version in two cases: > 1) some newly introduced bug is knowingly affecting a lot of users; > 2) the amount of improvements and bug fixes is large enough to justify an update ? typically, a few dozens of each, but there is no rule. > > Currently we are cleaning up GIMP code for v2.10 release some time in 2017.
