F5 is changing the standard support phase of the BIG-IP software lifecycle for Long-Term
Stability (LTS) releases from five (5) years to four (4) years. This means that EoSD and EoTS dates will now be reached 4 years
after individual versions are released, with this change remaining in effect for all
subsequent BIG-IP LTS releases. As F5 shifts to deliver more software-based solutions this
change is intended to maintain alignment with the industry, while also helping facilitate
migration of customers BIG-IP's to newer versions.
