As of a few minutes ago, https://ci.lsst.codes build notifications are being sent to the slack lsstc org in the #dm-jenkins channel. This is in parallel with the existing hipchat notifications, which will be maintained for a overlap period (TBD) with slack notifications.
A few jobs have been renamed as part of some general house keeping work. The changes possibly relevant to general users are:
run-rebuild -> release/run-rebuild
run-publish -> release/run-publish
