3.0.1 - 2023-05-11
This is a patch release of JDemetra+ v3.0.1.
Its sole purpose is to simplify the installation by providing Windows-specific binaries in addition to the platform-independent packages.
These binaries are self-sufficient and therefore don't require Java anymore.
Install instructions are available at https://github.com/jdemetra/jdplus-main#installing.
- Add Windows binaries to release
3.0.0 - 2023-05-02
This is the initial release of JDemetra+ v3.0.0.
Java SE 17 or later version is required to run it.
