What is the Ubuntu release strategy?

Releases of Ubuntu get a development codename (‘HirsuteHippo’) and are versioned by the year and month of delivery. LTS or ‘Long Term Support’ releases are published every two years in April. LTS releases are the ‘enterprise grade’ releases of Ubuntu and are used the most. An estimated 95% of all Ubuntu installations are LTS releases. Every six months between LTS versions, Canonical publishes an interim release of Ubuntu, with 21.04 being the latest example. These are production-quality releases and are supported for 9 months, with sufficient time provided for users to update, but these releases do not receive the long-term commitment of LTS releases.
