# Builds of tagged revisions are published to sonatype staging.
# Travis runs a build on new revisions and on new tags, so a tagged revision is built twice.
# Builds for a tag have TRAVIS_TAG defined, which we use for identifying tagged builds.
# Checking the local git clone would not work because git on travis does not fetch tags.
# The version number to be published is extracted from the tag, e.g., v1.2.3 publishes
# version 1.2.3 using all Scala versions in build.sbt's `crossScalaVersions`.
# When a new, binary incompatible Scala version becomes available, a previously released version
# can be released using that new Scala version by creating a new tag containing the Scala and the
# JVM version after hashes, e.g., v1.2.3#2.13.0-M1#8. The JVM version needs to be listed in
# `.travis.yml`, otherwise the required build doesn't run.
