v1.18.2 — Cleaner bibliography exports, and Search relevance that means it

Fixed

• Bibliography exports were silently corrupting or dropping entries. Two places — the editor's toolbar BibTeX/RIS export and Account → Export My Data — had their own hand-rolled citation writers that had drifted from the library's proper export code. An &, %, #, or _ in a title or journal name could break the resulting .bib file or corrupt it on import into Zotero/EndNote, and two sources by the same author in the same year could silently collapse into a single entry instead of two. Both now go through the same shared, tested writer the rest of Folio already uses, so a .bib/.ris file downloaded from anywhere in the app is consistent — special characters are escaped and every entry keeps its own citation key. If you exported a bibliography before this fix and it looked broken or came up short an entry, a fresh export should now be complete. See Exporting your document and bibliography.
• Search's "Relevance" sort wasn't actually relevance-ranked. On the main Search page, sorting by "Relevance" showed results in raw, per-source order rather than ranking them — so an old, heavily-cited paper from an unrelated field could outrank the on-topic result you were looking for. Relevance sort now uses the same semantic + citation + recency blend that Discovery Agents, Radar, and the Top tab already rank by.

See Searching the literature with Folio Search and Using Research Radar for how relevance ranking works elsewhere in Folio.
