Which software image for LTM and GTM

11.5.x8-April-20148-April-20198-April-202011.5.4

In my opinion:

1) NEVER run a ".0" release of ANY software in production.

2) ALWAYS wait for a Long Term Support (LTS) release.

There are companies / consulting firms where breaking either of the above is an automatic disciplinary investigation.

If you are installing in a lab / sandbox environment, then chase and investigate features, but in production, most enterprises value stability above all else...
