> This problem was introduced in 1.12.0 and is present in all lines derived from that one, including 9.10, 1.13, and current develop/1.14
> What's actually happening is that the locator _is_ upgraded to a newer version. It joins with an older coordinator (that's running e.g. 1.12.0) and that coordinator produces a view showing the new locator/member as running the same version, in this case 1.12.0, as the coordinator.
> Eventually, all locators will be upgraded. But the view carries the incorrect version indication.
> The root cause seems to be that when {{GMSMemberData.setVersionObject(short versionOrdinal)}} sees a version ordinal that is unknown, i.e. a version ordinal corresponding to a new line of development: 1.13, 1.14, … that method throws away that version ordinal and replaces it with the one for the 1.12 line.
> Since the current {{support/1.13}} and {{develop}} branches have the bug upgrading a current 1.13 to 1.14 or a current development/1.14 to 1.15 would exhibit the same behavior (locator apparently stuck at the older version in the view.)
> Ramifications of this incorrect version indication in the view are TBD.
> Whether or not this situation resolves itself after _another_ round of restarts is TBD.
