Installer link to Release Notes points to a non-existing page

When trying to install Dagda the first step of the installer prompts the user:
"You may wish to read the _release notes_".

When clicking on the link it goes to http://trisquel.info/en/wiki/dagda which returns a "Page does not exist: dagda" error and suggests that I can create the page. I would assume that the above link should redirect to http://trisquel.info/en/trisquel-50-release-announcement or at least be an alias of the Release Announcement page.
