What changes are you suggesting?

The docs state the following:

Under Supported versions, "Any version" refers to support for all versions of the language or tool including versions newer than the Default version.

The following Ruby versions (and their associated release date) are newer than the default version 3.4.4 and aren't yet supported on the platform:

Ruby 3.4.8 2025-12-17
Ruby 3.4.7 2025-10-07
Ruby 3.4.6 2025-09-16
Ruby 3.4.5 2025-07-15

Trying to use them by setting .ruby-version results in the following error:

08:24:04.528 Detected the following tools from environment: ruby@3.4.5
08:24:04.529 Installing ruby 3.4.5
08:24:04.743 Version not found
08:24:04.743
08:24:04.743 If this is a new Ruby version, you may need to update the plugin:
08:24:04.744 asdf plugin update ruby

Here (private Cloudflare link) for a run that errored out.

The existing documentation is confusing and surprising to users, who expect any version to be supported. It would perhaps be better to provide the exact list of supported versions.
