Right Version for the Task
Intent:
Problem
During the software lifecycle, there may exist several distinct incarnations of a software system. In general, they are identified by the version number and release number. Usually you will have at least two different releases. There will be a stable release, which is the one advertised for end user and is indicated for production usage. In parallel, there will be a development release, which is not ready yet for wide consumption, but where the development of new features happens.
Solution
Use the latest stable release for bug fixing activities. Use the development version for the development of new features, and for everything else that is not the correction of existing defects.
