 ### Changed
 
 - **Faster formatting after an edit.** Adding, editing, or removing one citation in a long bibliography reformatted every entry on the server, since the formatter cached whole bibliographies. It now also remembers each formatted entry per style, so it formats only the entries that changed: about 5 ms instead of 65–105 ms for a 200-entry list.
+- **Internals, for contributors.** No change to saved markup or output. The main plugin file is split into `includes/` modules (1,607 → about 800 lines), as are `includes/save-markup.php` and `src/lib/parser.js`; JS and PHP read one style table, `includes/styles.json`; Psalm runs at level 2 and `src/lib/` is type-checked with `checkJs` in CI; PHPCS checks PHP 7.4 compatibility; the runtime matrix runs the Abilities API. See `docs/planning/refactor-and-standards-memo.md`.

 ## Recent Release Highlights
 
+- **1.12.0** — Bibliographies read correctly in newsletters and feeds (no blanket italics or broken Cite / Export panel); names with particles sort per style; no period after a "?" or "!" title; reformatting after an edit renders only the changed entries; opt-in write abilities (WordPress 6.9+) wrap the write routes.
 - **1.11.0** — Cited works are nested in one JSON-LD `ItemList`, so link previews such as Mastodon's no longer credit a cited source as the post's author (published posts are corrected as they render); bibliographies over 50 citations format again.
 - **1.10.0** — Imports library catalog numbers (OCLC, LCCN, Open Library edition IDs) and Internet Archive items and ARKs through Open Library and the Internet Archive; "Edit fields" works on every citation and saves only the fields you change; an optional Google Books API key (constant or filter) for the ISBN fallback; "Place: Publisher" and CJK author names parse correctly.
 - **1.9.1** — Pasted CSL-JSON (a reference manager's CSL JSON export) imports as citations; a quoted title, such as a Chicago web page, is no longer also italicized; the JSON-LD DOI link keeps its slash.

 == Changelog ==
 
+= 1.12.0 =
+* **Added:** write abilities for AI agents and automation on WordPress 6.9+ (add, update, delete, and reorder citations; change a bibliography's settings or style). They exist only when a site turns on the write routes with the `bibliography_builder_enable_write_routes` filter, and follow the same rules: `edit_post` on the post and a preview unless asked to save.
+* **Fixed:** bibliographies in newsletters and feeds. Posts sent by email (Jetpack and WordPress.com newsletters, MailPoet, WooCommerce, Newspack) or read in a feed reader no longer show every reference in italics or a broken Cite / Export panel. Posts saved earlier are cleaned up as they are sent, and switch to the new markup the next time they are saved.
+* **Fixed:** names with particles ("van Duijnhoven", "de la Cruz") sort where each style puts them: under the surname proper in Chicago and Vancouver, under the particle in APA, MLA, Harvard, and the others.
+* **Fixed:** no period after a quoted title that ends in "?" or "!" in Chicago and MLA.
+* **Changed:** reformatting after an edit is much faster in long bibliographies: only the changed entries are formatted, about 5 ms instead of 65–105 ms for 200 entries.
+* **Changed:** internal restructuring and stricter static analysis, with no change to saved markup or output.

 = 1.11.0 =
 * **Fixed:** link cards no longer credit a cited source as the post's author. The JSON-LD listed cited works as top-level objects, and Mastodon takes the first top-level `WebPage` on a page to be the page itself, so a post citing a museum's collection page was shared "by Albertina". Cited works are now nested in one schema.org `ItemList`. Published posts are corrected as they are rendered, without being edited.
 * **Fixed:** bibliographies over 50 citations. The server formatter now takes up to 200 entries per request, matching the editor, instead of falling back to plain titles with a "Formatter unavailable" notice.
