v1.12.3

Quote posts on X can stay on X, and X links get proper cards on Bluesky and LinkedIn.

Features

• Only on X. With other platforms selected, a quote on Global goes to all of them as a plain link. Only on X on the quote card keeps the quote for X alone: X gets its own tab holding the quote, and the others get the text without the link. Only the card you click changes, and a card holding only the quote has no button, since the others would get an empty post.
• Share with all. On the X tab, Share with all gives the other platforms the link again. When X's text then matches Global, X follows Global again and its tab goes away.
• Better cards for X links on Bluesky and LinkedIn. CogSend builds these cards itself, and x.com gives a server only "Name (@handle) on X". A link to an X post now gets a card with the post's author and text from X's oEmbed endpoint, with the image from the post's page. If oEmbed fails, the card is what it was before. Mastodon and Threads build their own cards and are unchanged.

Fixes

• Dependencies updated to clear two high-severity npm audit advisories: the MCP client (@modelcontextprotocol/client 2.3.1) and sharp, which wrangler's local dev server uses and which is lifted to 0.35.5 until wrangler ships it.

Documentation

• Writing and publishing describes Only on X, Share with all and the new X link cards.
