[dependabot[bot]]

Bumps scala-library from 2.12.17 to 2.12.18.

Release notes

Sourced from scala-library's releases.

Scala 2.12.18

This release improves compatibility:

• Support JDK 20 and 21 with ASM 9.5 upgrade, by @​Philippus (#10185, #10362)
• Fix crash reading JDK 21 classfiles (#10397)

It also aids migration to Scala 2.13 and Scala 3:

• Under -Xsource:2.13, warn when inherited takes precedence over outer definitions (#10297, #10321)
• Under -Xsource:2.13, flag eta-expanding methods without parameter lists (#10283)
• Under -Xsource:2.13, don't GLB binders of type patterns, use the type directly (#10298)

and improves linting:

• Lint for integral divisions that are widened to a float (#10313)

and enables improved tooling:

• Preserve tree attachment in the typer's Block/Apply inversion transform (#10176)

For complete 2.12.18 change lists, see all merged PRs and all closed bugs.

Compatibility

As usual for our minor releases, Scala 2.12.18 is binary-compatible with the whole Scala 2.12 series.
