Will 2018 IRD, year-end updates support Sage 100 v2017?

Posted By FormerMember

My firm is currently on Sage 100 v2017.  We've delayed the upgrade to v2018 because of the complexity of upgrading payroll for each company; we have many companies for which we do payroll.  What I'd like to know is whether the forthcoming 2018 IRD year-end updte will be released for v2017, as well as 2019 Q1 Tax Tables?  Or will the 2018 IRD only support v2018 and v2019?  It's late enough in the year we really hope to postpone the upgrade to v2018 until next calendar year, but if we must upgrade to facilitate year-end updates we need to begin ASAP.  Thanks for your insight and support.
