LinkedIn fixed. LinkedIn rebuilt its post composer in September and the HQ button stopped appearing on the share page. This version recognizes the new editor and inserts through its own paste handler, so paragraphs come through intact.

Security hardening. The article panel now lives in a closed shadow root, so scripts on the sites you post to can no longer read your draft titles out of it, and the buttons ignore synthetic clicks a page could fake. Your login token was never exposed. Updating is still worth doing today.

Instagram support. The HQ button now appears on the caption box in Instagram's create flow, after you pick your photo. Pick an article and the Instagram version, caption plus hashtags, drops straight in. DMs and comment boxes are left alone on purpose.
