v0.4.2

FeatherReader 0.4.2 adds a public feature page for standard.site and a short list of recent releases. A feather-reader.com link posted to Bluesky or elsewhere now unfurls with a description and an image.

Full engineering detail is in CHANGELOG.md.

Upgrade notes

• No schema change and no new settings. Upgrading from 0.4.1 is a deploy, and rolling back to 0.4.1 is a redeploy. Both were rehearsed on a fork of a production volume. 0.4.2 booted with db: ok and served its link cards and share image. Then 0.4.1 booted on the result, also with db: ok.
• Link cards build absolute URLs from FEATHERREADER_PUBLIC_URL, the setting OAuth already uses. When it's unset, the cards point at the development default. Set it to your public origin.

Added

• A feature page at /standard-site (#237). It explains:

  • what a standard.site publication is;
  • what FeatherReader shows from one: title, date, link and a plain-text summary;
  • how to subscribe;
  • the limits.

  The how-to-subscribe part appears only when FEATHERREADER_STANDARD_SITE is on. The landing page, /about and the footer link to the page.

• A "latest releases" section on /standard-site and the landing page (#237). It links each release's GitHub page and changelog entry. The list lives in one place, web::RELEASES, and a test requires its newest entry to match the crate version. A release can't ship without adding itself.

• Link cards on every page (#238):

  • Each page: a meta description, a canonical URL, Open Graph tags and a summary_large_image Twitter card.
  • Public pages: their own title and description.
  • Signed-in pages: the generic site card, plus noindex. No handle or DID appears in the page head.
  • The share image: static/social-card.png, 1200×630, 69 KB, generated from a committed SVG by scripts/social-card.sh.
