Is it 4.2.176 or 5.2.157?
I'm running 5.2.157 and it's not listing at its 'latest'. Am I missing something here?
No you wouldn't. Which means, as of the latest, Cisco does not see any bugs or vulnerabilities regarding this firmware. It will give you an idea as to what firmware you should settle yourself into.
It looks to me like they "publicly" released the information today... but that the fixes have actually been implemented for awhile..
I think the big deal is that the software is "free" for those people who may not have software contracts.... Or at least to let people know to update that haven't recently..
