[ESS] ESS 25.1.0 listed as 'obsolete' when upgrading from MELPA?

[Kevin Zembower]

Hello, all,

Trying to prepare for the upcoming semester, when I'm taking Basic
Statistics. I tried to upgrade ESS to 25.1.0 from the MELPA Stable
repository. When I do 'M-x package-list-packages', I see (first line,
and second line from the bottom; sorry how my email client is breaking
the lines):

Any ideas of what I'm doing wrong, or how to fix things? Thanks for any
advice or guidance. Using Emacs 29.3.
