* Add a Scala 2.13 build pipeline This adds initial support for multiple Scala versions controlled via the DAML_SCALA_VERSION env var and a CI job to make sure we don’t regress. For now we only test //libs-scala/ports/... which seemed like the easiest starting point I could find. We can incrementally expand that over time. changelog_begin changelog_end * Document pinning changelog_begin changelog_end * Address review comments changelog_begin changelog_end
