We may also use it for automation purposes, like generating changelogs or notification emails.\n\nYou can fix this by adding the Id in one of the styles below to the commit message\n[Delivers #12345678]\n[fixes #12345678]\n[finishes #12345678]\n[#12345884 #12345678]\n[#12345884,#12345678]\n[#12345678],[#12345884]\nThis will address [#12345884]"
