BlueJ 4 also adds support for Stride, our frame-based programming language. Projects can be pure-Java (as in BlueJ 3 and earlier), pure Stride or a mix of Java and Stride. Support is providing for converting between Java and Stride.
BlueJ 4 adds support for the Git version control system (and retains support for Subversion).
Note: BlueJ 4 requires Java 8 (minimum 8u60) and JavaFX, and thus is currently unsupported on older Macs and on Raspberry Pi. Support for CVS, JavaME projects, and applet development has been removed. Some extensions may no longer work in BlueJ 4.

In the absence of any major issues, it will be the last version of BlueJ which will work with Java 6.
List of fixes and improvements:
Fixed problems in handling SVN projects. Fixed minor issues with the debugger. Note that from this version, to work around bugs in the SVNKit library that BlueJ uses for Subversion support, BlueJ projects which are shared to or checked out from a repository will use the (old) version 1.6 working copy format. This may mean that some external tools (including recent versions of the subversion command line client) may not be able usable with BlueJ projects. Projects checked out or shared using BlueJ version 3.1.6 used the version 1.7 working copy format and will not work properly (in any version of BlueJ) due to SVNKit bugs; BlueJ version 3.1.7 will issue a warning when opening such a project.
