9800 IOS 17.9.5a/b and APSPs

[eglinsky2012]

I've been seeing "fixed versions" in bug notes recently including versions 17.9.5a and 17.9.5b for 9800 WLCs. I do not see those versions on the software download page. Are these escalation builds, upcoming public releases, etc.? Here are all the 9800-80 bugs resolved in 17.9.5b: https://bst.cloudapps.cisco.com/bugsearch?pf=prdNm&prdNam=Cisco%20Catalyst%209800-80%20Wireless%20Controller&kw=*&bt=custV&sb=fr&rls=17.9.5b Several of those bugs that I clicked on are only fixed in 17.9.5b. Or is it normal for unpublished a or b versions to exist?

Also, is anyone aware of any 17.9.5 APSPs coming soon? I'd have thought there'd have been one by now.

I'm currently running 17.9.4a/APSP8 with a variety of APs from 2700 series on. As has been discussed on this forum, it's a buggy release, and I'd like to upgrade this summer but am trying to decide whether to go to 17.9.5 now, wait until a newer version  (or at least APSP) potentially gets released (say by mid-July), or roll the dice on the "ED" 17.12.3 (or wait for 17.12.4).

Our six 9800-80 are now on 17.12.3. 

First off, we've seen the re-introduction of CSCvr50556 spamming our syslogs like a broken record.  Rebooting the AP is a temporary workaround and will return after a few hours.  

Anyone planning to upgrade to 17.12.3 need to compare the WLC config after the upgrade because we've seen missing lines of config in all six controllers.

What parts of config @Leo Laohoo 

We've also decided to go with 17.12.3 - will be starting with it soon
(saw reloads on lab with 17.9.5 which TAC can't seem to explain!)

<facepalm>

And which parts of the config did you see going missing?

Still trying to compile.

Could be either but also because 9800 shares the IOS-XE code base with numerous other platforms now, you'll sometimes see new versions which have been rebuilt only for a specific platform but they appear as fixed for all platforms sharing the same code base.
