 # revealjs.ids (development version)
 
+- Documents with a `bibliography:` in their YAML header are now formatted with the bundled IDS citation style by default (`ids.csl`, based on the style developed for ICLC-10 2023 in Mannheim). A `csl:` entry in the document's YAML header still takes precedence.
+
 - Speaker timing comments in the source `.Rmd` (e.g. `<!-- JD 00:30 -->` for "John Doe needs 30 seconds for this slide", or just `<!-- 00:30 -->` for single-speaker talks, ported from the old Google Docs workflow) are now converted into `data-timing` attributes on the rendered slides' `<section>` elements, activating the pacing timer in the reveal.js speaker view (the calculated grand total is passed as the `totalTime` config value; a `totalTime` or `defaultTiming` set by the document itself, e.g. to start from a known time budget, takes precedence). A per-speaker time summary is printed during rendering, and the new `slide_timing()` function computes slide, speaker, and grand totals directly from an `.Rmd` file without rendering it.
 
 - `ids` theme: bold ("highlighted") text now uses orange Fira Sans Condensed (600, 90% size) instead of just an orange colour in the serif body face, as in the IDS reference decks.
