1.7.1

• .node-version and .tool-versions pin Node 26.13.0, the current LTS
  release, and the GitHub Actions workflows run on Node 26, including the deploy
  and course-check workflows a course project inherits. The requirement does not
  change: Node 24 still works, so a course author on 24 need do nothing.

• The dependencies are upgraded to their newest releases, all within the range
  package.json allows: @vscode/vsce to 4.1.0, eslint to 10.14.0, globals to
  17.14.0, marked to 18.1.3 and turndown to 7.2.5, along with the transitive
  tree. marked's two releases fix parser bugs, so unusual markdown (emphasis
  delimiter runs, lazy lines in a blockquote, link labels) can render
  differently. The pages shipped in course/ render exactly as before, and a
  page already on Canvas changes only when a push next renders it. Run
  npm install after the upstream update, as the update script reminds you to.
  npm audit still reports advisories in the Docusaurus build and preview
  toolchain and in eslint and @vscode/vsce. npm audit fix still resolves the
  Docusaurus ones by nesting an older Docusaurus, and the only fix it offers for
  the other two is a downgrade, so leave it alone.
