[lynxlynxlynx]

• write a news post
• announce everywhere: See release docs
• redirect the domain https://help.github.com/en/github/working-with-github-pages/configuring-a-custom-domain-for-your-github-pages-site (currently just redirected at server level, losing the domain)
• update any broken links in the main repo files
• ask Cam to put the url in the discord title
