# Release notes

## [v1.10.0](https://github.com/VirtusLab/scala-cli/releases/tag/v1.10.0)

### Change default Scala versions to 3.7.4 and 2.13.17
This Scala CLI version switches the default Scala versions:
- default Scala 3 to 3.7.4
- default Scala 2.13 to 2.13.17

```bash
scala-cli version
# Scala CLI version: 1.10.0
# Scala version (default): 3.7.4
```

Added by [@Gedochao](https://github.com/Gedochao) in https://github.com/VirtusLab/scala-cli/pull/3942 and https://github.com/VirtusLab/scala-cli/pull/3895

### Support for the new Scala 3.8 REPL
As per https://github.com/scala/scala3/pull/24243, Scala 3 REPL has been extracted to [a separate artifact](https://repo.scala-lang.org/ui/packages/gav:%2F%2Forg.scala-lang:scala3-repl_3/3.8.0-RC1-bin-20251101-389483e-NIGHTLY)
in Scala 3.8, as a result of which the use of the REPL command with Scala 3.8.0-RC1-bin-20251101-389483e-NIGHTLY
or newer will require upgrading Scala CLI at least to 1.10 to work.

```bash ignore
scala-cli repl
# Welcome to Scala 3.8.0-RC1-bin-20251101-389483e-NIGHTLY (23.0.1, Java OpenJDK 64-Bit Server VM).
# Type in expressions for evaluation. Or try :help.
#
# scala>
```

Added by [@Gedochao](https://github.com/Gedochao) in [#3936](https://github.com/VirtusLab/scala-cli/pull/3936)

### Support for adding extra directories to a Docker image
This feature adds the ability to include additional directories in Docker images.
Users can now specify extra directories to be copied into a Docker image during the build process.
The directories can be passed with the `--docker-extra-directories` command line option or `//> using packaging.dockerExtraDirectories` directive.

```scala compile power
//> using packaging.dockerExtraDirectories path/to/directory1 path/to/directory2
```

```bash ignore
scala-cli --power package . --docker --docker-image-repository repo --docker-extra-directories path/to/directory
```
Added by [@btomala](https://github.com/btomala) and [@Gedochao](https://github.com/Gedochao) in https://github.com/VirtusLab/scala-packager/pull/250 and https://github.com/VirtusLab/scala-cli/pull/3908

### Deprecate support for building GraalVM native images with Scala pre-3.3
When building GraalVM native images with Scala CLI and Scala versions older than 3.3.0, the following warning will now be printed:
```bash ignore
# [warning] building native images with Scala 3 older than 3.3.0 is deprecated.
# [warning] support will be dropped in a future Scala CLI version.
# [warning] it is advised to upgrade to a more recent Scala version
```
While the native images will still be built, the functionality will be removed in a future Scala CLI version.
It is advised to migrate projects to Scala 3.3 or newer.

Additionally, the following modules have been dropped and will no longer be published:
- `scala3-runtime`
- `scala3-graal`
- `scala3-graal-processor`

As they remain necessary for building native images for Scala pre-3.3 projects,
their usage has been deprecated and frozen at respective version 1.9.1.

Added by [@Gedochao](https://github.com/Gedochao) in [#3929](https://github.com/VirtusLab/scala-cli/pull/3929)

### Stop publishing certain modules for Scala 2
While it is technically an internal change, it is worth noting certain Scala CLI modules will no longer be published for Scala 2.
Those include:
- `runner`
- `test-runner`
- `tasty-lib`
- `config`
- `specification-level`

From this point on, they will only be published for Scala 3.
