v1.0.0-RC1

Official scala runner release candidate

v1.0.0-RC1 is the first release candidate version of Scala CLI.

Either this or a future release candidate is meant to become the new official scala runner to accompany
the Scala compiler (scalac) and other scripts, replacing the old scala command.

To learn more about Scala CLI as the new scala runner, check out our recent blogpost:

Scala CLI should now have better performance

With a number of newly added performance tweaks, you can expect Scala CLI to run considerably faster.
Added by @lwronski in #1939

Print appropriate warnings when experimental features are used

Using experimental features will now cause Scala CLI to print an appropriate warning.

scala-cli --power -e '//> using publish.name "my-library"'
# The '//> publish.name "my-library"' directive is an experimental feature.
# Please bear in mind that non-ideal user experience should be expected.
# If you encounter any bugs or have feedback to share, make sure to reach out to the maintenance team at https://github.com/VirtusLab/scala-cli

The warning can be suppressed with the --suppress-experimental-warning option, or alternatively with the
suppress-warning.experimental-features global config key.

scala-cli config suppress-warning.experimental-features true

Added by @Gedochao in #1920

Experimental and restricted configuration keys will now require to be accessed in --power mode

Some configuration keys available with the config sub-command have been tagged as experimental or restricted and will only be available in --power mode.

scala-cli config httpProxy.address
# The 'httpProxy.address' configuration key is restricted.
# You can run it with the '--power' flag or turn power mode on globally by running:
#   scala-cli config power true.

Added by @Gedochao in #1953

Dropped deprecated using directive syntax

The following syntax for using directives have been dropped:

• skipping //>
• multiline directives
• directives in /*> ... */ comments
• directives in plain // comments
• @using

Added by @tgodzik in #1932

Added support for packaging native images from Docker

It is now possible to package a GraalVM native image with Scala CLI from docker.

docker run -v $(pwd)/Hello.scala:/Hello.scala virtuslab/scala-cli package --native-image /Hello.scala

Added by @lwronski in #1961

Added support for Scala Native's LTO

It is now possible to set the Link Time Optimization (LTO) when using Scala CLI with Scala Native.
The available options are "thin", "full" and "none".
You can do it with the --native-lto option from the command line:

scala-cli -e 'println("Hello")' --native --native-lto thin

Or with a using directive:

//> using platform "scala-native"
//> using nativeLto "thin"
@main def main(): Unit = println("Hello")

Added by @lwronski in #1964
