XC 184.108.40.206.* has already progressed to XC 220.127.116.11 with a changelog that shows many fixes as well as one improvement. We're guessing these observations came from developer access level users, so at least that appears to be working well. However, the not mentioned in the blog
but still shown clearly on the changelog
XC 18.104.22.168 release, which we're assuming will be separate and required before
progressing to XC 5.3.4.* we still can't see (at merchant level) in any store. This was released on 31st October which is 10 days ago now. 10 days is around the usual time previous upgrades have moved from dev to merchant access level status. We're actively chasing bug-fix releases... Is the XC 22.214.171.124 imminent?
