I also don’t use Mint personally, but based on their releases page, it looks like they follow the Ubuntu LTS releases. The latest LTS version of Ubuntu is already being used for Mint 22.1, so I wouldn’t expect to see Gimp 3 until the next LTS release in April of 2026.
Debian based distros are notorious for using old, but known stable packages. That’s kind of their whole thing. If you want the latest and greatest, look for a rolling release based distro.
