[SethTisue]

@ashawley are you available to publish scala-xml today? if not, someone on the Scala team can do it

@Sciss are you available to publish scala-swing?

@sjrd I know you're all over it without even asking

[Sciss]

@SethTisue I think I never actually ran the publish action, and I'm quite busy until end of next week, but I could simply push the necessary changes into the repository for someone else to handle the Sonatype thing?

[SethTisue]

@Sciss releasing a module involves these steps:

1. module maintainer makes any necessary source changes
2. module maintainer pushes a tag
3. if it's a new module version, please also write release notes (not applicable if back-publishing existing version for new Scala version.)
4. Travis-CI automatically stages the release on Sonatype
5. (upon request by module maintainer) Scala team member optionally sanity checks the staged JARs, then hits "release"

see https://github.com/scala/scala-swing/blob/work/admin/README.md
