Release notes – scala3-3.3.0.msi

General informations

• scala3-3.3.0.msi (119 MB) is a self-signed Windows installer built from scala3-3.3.0.zip (33 MB), scala3-library_3-3.3.0-javadoc.jar and scala-library-2.13.10-javadoc.jar.
• The installation context is per-machine, not per-user.
• The installer targets 64-bit Windows systems (MS Windows 7 or newer); it was tested on Win10 Pro/Home and Win11 Pro.
• The project description is available on page README.md (GitHub project michelou/wix-examples).

What if a Scala 3 installation is already present ?

The Windows installer behaves in 3 different ways when it detects a Scala 3 installation on the user machine :

• if the version to be installed is newer than the version found on the machine then the Windows installer removes the old version and installs the new one.
• if the version to be installed is older than the version found on the machine then the Windows installer does exit.
• if the version to be installed is the same as the version found on the machine then the user is asked for a change, repair or remove operation.

Running the Scala 3 Windows installer does...

• trigger an elevation of privileges (tested many times but "usage at your own risk" disclaimer).
• install the application files to the selected destination folder (default location is : C:\Program Files\Scala 3\).
• add the small wrapper script bin\repl.bat which gives direct access to the Scala 3 REPL.
• [✗] create shortcuts under the Start Menu folder "Scala 3".
• [✗] add variable SCALA3_HOME to the Windows system environment.
• [✗] append path %SCALA3_HOME%\bin\ to the system variable PATH.
• [✗] install the API documentation to the selected destination folder (default location is : C:\Program Files\Scala 3\).

Note: [✗] Optional feature enabled by default.
