I used the word "eventually" as a hint — it isn't going to be soon. I'm
sure there will be notifications when that does come up, but the
Accelerator still has 2 IOCs running Base-3.13.10 (I was hoping they'd
get be converted to Base-3.14.12.5 during this last shut-down, but in
the end that wasn't possible). Currently we only using 3.15 in a very
few systems that are really development IOCs for the APS Upgrade. We
aren't going to be converting our roughly 500 production IOCs to a newer
Base release too quickly, and I suspect we will still have some 3.14.12
IOCs in the injector area at least after we come out of the APS Upgrade
dark period.
