JarCastingscala-collection-contrib
This module provides various additions to the Scala 2.13 standard collections.
Usage
If you're using sbt, you can add the dependency as follows:
libraryDependencies += "org.scala-lang.modules" %% "scala-collection-contrib" % "0.2.2"
Here is the full Scaladoc.
New collection types
These collections are in the scala.collection package.
MultiSet(both mutable and immutable)SortedMultiSet(both mutable and immutable)MultiDict(both mutable and immutable)SortedMultiDict(both mutable and immutable)
New operations
The new operations are provided via an implicit enrichment. You need to add the following import to make them available:
import scala.collection.decorators._
The following operations are provided:
BitSet: <<, >>, ...mutable.BitSet: <<=, >>=, ...Iterable: foldSomeLeft, lazyFoldLeft, lazyFoldRight, splitBy, ...Iterator: intersperse, foldSomeLeft, lazyFoldLeft, lazyFoldRight, splitBy, ...Map: fullOuterJoin, leftOuterJoin, mergeByKey, mergeByKeyWith, rightOuterJoin, zipByKey, zipByKeyWith, ...Seq: intersperse, replaced, splitBy, ...
Maintenance status
This module is community-maintained. If you are interested in participating, please jump right in on issues and pull requests.

scala-collection-contrib's merge policy is liberal: we're happy to merge most things here, without too much review, so that people can try them out.
There is now (as of October 2020) the scala-library-next repo, which is where we decide what will actually be added to the next version of the Scala standard library. The standards for merging things there are much more conservative.
Releasing
As with other Scala standard modules, build and release infrastructure is provided by the sbt-scala-module sbt plugin.
