The GNU Image Manipulation Program was developed as a software project and is available to users for free. The GNU in the named is involved because it was developed under its banner. The software is a multi-platform support and works equally well on all operating systems. GIMP is developed on public mailing list and in the IRC network. It is distributed as a public source code. The work of developing more and more features for it continues under the separate source code branches. However, the updates are not attached with the software right away.

There had been updates such as the healing brush, which was created in 2006; however, it’s only available with the latest version of GIMP. This means that development of GIMP’s improved version could take more than a few months, if not years. The source code is released for GIMP, which is then converted to installer setups for different operating systems separately.

There are version numbers attached to every release. They are denoted as Major. Minor, Micro formats. These three ‘Ms’ have their own significance in a way of representing the software. The Major number is only changed when the level of development is considerably high, which means that there is a big change in the user’s appearance, features and interface. Right now, the Major for GIMP is 2.

The next number is Minor, which is updated after a specific feature is added. In Micro, there are two types of numbers; the even number such as 2.2 will represent a stable version of GIMP, while and odd number as 2.3 means that the work for the update is in progress. This is just a method to inform the user about the errors they might face in running the unstable versions.

The Micro number is used for any type of release that is with or without bugs. There is no specific method of numbering other than the fact that the even numbers are used for successful release, while odd numbers represent development in progress. Hence a version of 2.6.2 means that the software is in complete working condition, while 2.3.7 means that there might be errors, which are being sorted out at the moment. The most recent release of GIMP version was 2.8.2, in November this year, which means a stable version of GIMP.

The GIMP user friendly interface is designed by a team dedicated only to create the interfaces. The GIMP users are also allowed to send in the suggestions regarding anything that they feel is lacking in the software or is not much wanted. This helps in making the software more user-friendly which is accepted by the users in general.

The photo editor was essentially presented in a single window; however, with the release of the latest version 2.8, there is now multiple-window mode available. In this new mode, the tools and settings are open in different windows, while other anonymous boxes open separately on the right side. GIMP teams also participate in event as Libre events where they discuss the software and any feature that could either by added or improved, continuing the process of development of the software.
