The Eclipse BIRT download site makes several types of builds available for BIRT. The following list describes these builds:
Release build
A production build that passes the complete test suite for all components and features. Use the release build to develop applications.
Milestone build
A development build that provides access to newly completed features. The build is stable, but it is not production quality. Use this type of build to preview new features and develop future reporting applications that depend on those features.
Stable build
A development build that is stable, but passes a reduced test suite. New features are in an intermediate stage of development. Use a stable build to preview new features.
