Even though I had the "Auto Update" enabled, it didn't happen. Thus, when I went to the IBM site to verify my version, I discovered (after the download) that the current version is 3.6.1507.14.
But what fixes, changes, etc.? Ah, now that I haven't a clue.
All said, the DL, install (with Captcha mid point), and restart were uneventful.
The only change I have so far noticed (if it is in fact new), is that the
Origin (USAA) is now displayed.
