BIG-IP 17.1

Support windows are getting shorter: the most recent cycles run about 15 months less than the earlier ones.

Computed from release and end-of-life dates tracked for BIG-IP. Medians are used rather than averages so one unusually short or long release does not skew the figure. Cycles with no recorded end-of-life date are excluded from the support window.
