As already stated, Popey has given you your answer. To add to that:
If you want the release date changed, Mark Shuttleworth is the person who makes these decisions. He doesn’t frequent this forum, so he won’t answer here.
In any case, he would demand an extraordinary and highly exceptional reason to even consider bringing the release date forward. It is, after all, a mere 2½ months away, far too late to make a significant change.
Your complaint, “Ubuntu 24.04 feels too limited for my needs and does not offer enough improvements for me personally,” does not count as sufficient reason in the slightest.
Ubuntu 22.04 is supported until 2032, not 2027, if you use Pro (free for personal use up to 5 computers).
Ubuntu 24.04 is supported until 2036 — that’s 12 years — if you use Pro.
Likewise, Ubuntu 26.04 will be supported until 2038 if you use Pro.
If you’re looking for the official release date, you can see the official release schedule, with the final release on 23 April 2026.
