Individual developers started collecting a few first candidates in https://docs.google.com/document/d/1svfo3L8aBirUPb0CR293TTUYxsHXd0S3AfdqqkPPdnk/edit#heading=h.80g64b9w7ejo. A few of them already made it to the WMDE-TechWish-Sprint-2023-11-22 board. I think we haven't really reviewed the Cite board systematically yet.

For reference, as part of this project I closed the following ~24 older tickets without action (e.g. declined or marked as obsolete/invalid):

• T10033: Allow hiding of Cite.php references
• T10167: support scientific or more generally bibtex/latex citation style
• T11091: Request Hook in Cite.php function stack
• T18294: Update to cite.php refs: ids fixed, footnotes, globbed links
• T18330: When nesting refs using cite.php extension, the ordering is wrong
• T20103: removal of principal named reference silently breaks others
• T23209: Provide new special pages for statistics on the number of references tags <ref> per article
• T24134: <ref> acting as a citation template using attributes of the ref element
• T24323: Tag cite error revisions
• T25455: Cite: Suppress backlink for a huge number of named references
• T30843: Cite error uses lego messages breaking localisation and customisation, should be deprecated
• T32763: Cite: If there's no <references /> block on the page, insert the wikitext for one automatically in the right place
• T36589: Content of <references/> not shown when other parser extensions are active
• T43442: Superscript reference numbers cause increase in line height with devanagari text
• {T56598}
• T58404: Add a hook to Cite to let other extensions cause <ref>, </ref> and everything in between to render as blank
• T111475: Integration tests in combination with Cite returns a Notice: Undefined property: Parser::$extCite
• T115809: Coded unreadable reference name in 3 media wiki messages in non-ASCII languages
• T127666: <references /> block should only show refs above it, not all refs on the page
• T132266: Line breaks between punctuation and footnote
• T236802: Blank page when CX is used without Cite
• T244890: cite button is generating incorrect isbn data for isbn 978-3-443-01063-8
• T245700: For talk pages have references occur in each section
• T337467: ref in #if is shown

The past weeks we already fixed the following smaller issues:

• T298278: Sometimes the link from the inline footnote marker down to the citation and back wouldn't work when the reference name contains certain special characters. This got finally fixed.
• T352179: For the same reason it was possible to see broken Reference Previews popups, e.g. when the reference name contains % characters.
• T332007: A similar issues in the mobile MinervaNeue skin also resulted in broken reference popups, this time because of the "#" character.
• T299280: We added a new error messages, relevant for the follow="…" feature used on Wikisource.
• As part of T299280 we improved a confusing error message that talked about "to many keys" for purely historical reasons (explained in T299280#9384546). The message correctly mentions "invalid parameters" now.
• T64335: A capitalized <REF> would sometimes cause weird numbering mistakes. The issue is so rare, it took 5 years before it got reported for the first time and 9 more years before it got fixed.
• As part of T321217 the messages cite_references_no_link, cite_reference_link_key_with_num, cite_reference_link_suffix, and cite_references_link_suffix have been removed. They have never been used for anything on Wikimedia wikis.
• We updated the codebase to use more recent coding standards like ES6.
