This is my only problem with it. I can’t imagine it stays like that. I feel like there has to be at least a year of overlap between release of one LTS and deprecation of support for the previous one. Or at least a commitment to continue with security patches for longer (while stopping bug fixes and enterprise support)
You'll be OK as long as you're dropping off suitcases of money at Oracle's door, but currently it appears that freely available fixes/security updates will cease as soon as the next LTS is released.
Are they dropping support for the latest LTS just four month after releasing a new LTS? That sounds a bit harsh.
