# 1.1 What is new in GMT 4.x?

GMT 4.x has continued to see both development of new features as well as corrections of legacy bugs and problems. However, the GMT 4.5.2 release is the last in the series to involve new options and enhancements. Beginning with GMT4.5.3 there will only be bug-fixes in the new releases as all development is now focussed on GMT 5; this new series will be distinguished by being completely restructured so as to allow developers to call high-level GMT processes from a variety of programming environments. Below is a brief history of the development milestones in the 4.x series. We expect to maintain the GMT4 series for some time after GMT5 is released later this year
