ISR4331 Router
Dear Experts,
I went to the cisco website to find the latest firmware for my client's router.
Currently the firmware is isr4300-universalk9.03.13.
In the downloads, i found:
3.13S
- 3.13.8S(MD)
- 3.13.7S(MD)
- 3.13.6aS(MD)
- 3.13.6S(MD)
- 3.13.5S(MD)
- 3.13.4S(MD)
- 3.13.3S(ED)
- 3.13.2S(ED)
I deduce that my client is using 3.13.4S(MD)
My account does not allow me to download 3.13.8s(MD) but I can download 3.13.7S(MD) but I am not able to review the version's release note, I clicked on the release note link and it brought me to https://www.cisco.com/c/en/us/support/ios-nx-os-software/ios-xe-3s/products-release-notes-list.html which I do not know which document to look at. As I cannot find the release note for 03.13.7S.
Can anyone please help me on this?

Hi! Predrag,
The caveats also do not have the version 3.13.7S.
On another note, the current router is running well with no errors, how can I write in my report to my client that there is no need to upgrade the router even though there are new versions available to upgrade the firmware?

Thanks Predrag
You're welcome.
Release Notes for the Cisco 4000 Series ISRs
Always check Open Caveats for your specific release to know which configuration can lead to problems and crashes of router.
As always, the newest IOS version is not necessary the best for customer (the best is always the one where customer operations are not affected by version bugs). Even version with bugs that are known (and not relevant for production) is better than newest version with yet unknown and undiscovered bugs.
