Markdown prose wrapping lands (
635d591)
Biome now supports configurable prose wrapping for Markdown paragraphs, adding a new prose_wrap formatter option with schema/config plumbing. The formatter changes are substantial and also touch inline code, links, quotes, list alignment, and service handling, so Markdown formatting should be noticeably more consistent across prose-heavy docs.
Markdown code and inline formatting get a major cleanup (8c8779d)
This pass expands the Markdown formatter to dedent code blocks, normalize string-like content, and fix a range of indentation edge cases in blockquotes, lists, inline code, and link titles. It’s a broad behavioral improvement that should reduce noisy diffs and make Markdown output more spec-aligned.
CSS comments keep their original indentation (
d890b39)
Line comments between a property colon and value now preserve their source indentation instead of being reflowed to the formatter’s preferred padding. That fixes a subtle but visible formatting regression in both CSS and SCSS property values.
YAML formatting gains better scalar and collection handling (
5060aa0, 67798d7, cba196d, a882bd9)
YAML formatting picked up several related correctness fixes: document separation, trailing newlines, explicit-form mapping keys, flow collection spacing/blank lines, and trailing comment handling in block scalars. Together, these changes make the YAML formatter much more reliable on real-world documents with complex scalar and collection layouts.
useNullishCoalescing learns to ignore if assignments (
c171b3b)
The lint rule now detects if statements that only assign a fallback value to a nullish variable and can rewrite them to ??=. A new ignoreIfStatements option lets users opt out of that reporting when they want to keep the if form.
--stdin-file-path now respects nested config (
a519f9d)
Biome’s CLI now handles stdin formatting/linting more correctly when the provided file path lives under nested configuration. This fixes a long-standing path-resolution bug that could cause stdin runs to ignore the intended local config and ignore rules.
Tailwind class sorting resolves bare functional utilities (
5c07dc4)
useSortedClasses now resolves bare functional utilities with defaults in sort_v4, improving sorting accuracy for Tailwind v4-style configs. That should reduce misordered class suggestions in projects relying on the newer preset behavior.
noDelete allows computed process.env deletion (
01f7ef5)
The performance lint was relaxed to allow deleting computed process.env expressions where it previously complained. This is a narrow but user-facing correctness fix for code that intentionally manipulates environment access.
