Cisco normally publish future releases as being fixed before the
releases become physically available. It is just a commitment from the
BU to say in which release a bug is going to get fixed. When the release
actually becomes available is orthogonal to the bug details.

We started using this platform back in 2014.

We are using the code that was the only one available back then -
15.1(2)SY2 - without any issue.

We were actually just about to start a round of upgrades to the latest
stable release, but after seeing this thread, best to wait.

In all fairness, we are running the switches as pure Layer 2 core
devices, but with lots of 10Gbps LACP links. No issues with that since 2014.

If you don't have any features that require anything beyond 15.1(2)SY2,
I'd suggest trying this if there aren't any defects in it worth noting
for your environment.
