I certainly would not post an older version as an upgrade.
FYI:
When comparing ConnectKey version numbers to determine older/newer
1)ensure you only compare those that start with the same first 3 digits (073),
2) then look at the last 6 digits only.
General release : 073.xxx.075.34540 - 5=2015. 345=day 345 of the year. 40 is respin 4.
SPAR release: 073.xxx.066.08210 - 6=2016. 082=day 82 of the year. 10 is respin 1.
073…534540
073…608210
608210 is a higher number than 534540.
The fixes and features that will be in the 073…5.34540 (general release) are also in 073…6.08210 (SPAR Release)
