Ubuntu Pro expands its Legacy add-on to deliver 15 years of security and compliance coverage for long-lived Ubuntu LTS deployments.
The change applies retroactively, starting with Ubuntu 14.04 LTS (Trusty Tahr), allowing businesses to keep using older Ubuntu LTS releases in production far beyond the usual lifecycle while still receiving critical security patches, compliance tooling, and optional support.
The Legacy add-on becomes available after the initial 10-year window and is priced at a 50% premium over standard Ubuntu Pro, whether users are approaching this milestone with Ubuntu 16.04 LTS or continuing Legacy coverage from 14.04 LTS.
Nothing on if this includes personal use and if that stays free.
Legacy is an optional add-on, with the standard ESM still 5 years post standard support...
ie. standard support is still 5 years, ESM is still five additional years, with the legacy add-on increased from two additional years to now five years. The standard and ESM support hasn't changed, only the legacy has 3 additional years.
I don't see the point to your last comment; the two years of legacy wasn't available without payment before; it's not now that its increased to five years, at least that's how I read/understood it.
standard support for 14.04 (using it as example) was 5 years, ending in 2019
extended support for 14.04 ended five years later in 2024; UNLESS you took up the optional legacy option which gave you a further 2 years (making it 12 total) which has expanded now to 5 (15 total).
The legacy option has increased from 2 years extra to 5 years extra, beyond the standard ESM/Pro of 5 years extra.
The additional 5 years for standard Ubuntu Pro/ESM is unchanged; only the legacy option was extended a further 3 years; so if you paid for that you can continue paying for an extra 3 years now and get 3 years longer updates/security-fixes.
