…ly renders the modern release bodies. Recent releases (v2.1.5 onwards) embed `<details><summary>` snippet blocks containing fenced Python code, and the previous m2r2 (markdown -> RST) pipeline pasted those code fences into `.. raw:: html` directives unchanged, so Sphinx surfaced literal backticks instead of syntax-highlighted snippets and re-declared the `:raw-html-m2r:` role on every release. The script now converts each release body to HTML via the `markdown` package (with `fenced_code`, `tables`, `attr_list`, and `md_in_html` extensions), strips the trailing `by @user in PR_URL` attribution while keeping the link, demotes Markdown ATX headings by one level so the page H1 still owns the top of the hierarchy, and emits a single `.. raw:: html` block per release wrapped in `div.uplt-whats-new-release-body` for styling. The `[bot]` suffix on `@dependabot[bot]` / `@pre-commit-ci[bot]` is now part of the attribution regex. Companion CSS rules in `docs/_static/custom.css` give the wrapper sane spacing for headings, the `<details>` affordance, code blocks, and inline images. The docs optional-dependency in pyproject.toml swaps `m2r2` for `markdown`. Adds `ultraplot/tests/test_docs_fetch_releases.py` exercising the raw-HTML wrapping, title formatting, three-space indent under the directive, the regression for code fences inside `<details>`, the empty-body and empty-API edge cases, and bot-account attribution stripping.
