What is Biome?

Biome's patch train keeps adding rules — and is quietly growing a Markdown linter.

Six patch releases since mid-June, each mixing new nursery rules with parser and formatter fixes. 2.5.8 adds useReactCompiler, which surfaces React Compiler's own lint diagnostics through Biome, and makes HTML style attribute values parse as CSS so every CSS rule applies inside them. Framework coverage keeps deepening — Svelte legacy {@const} tags, Vue instance properties, Tailwind arbitrary values — and the JavaScript API package reached 6.0.0 with a byte-to-UTF-16 span helper.

What is Buildkite?

Buildkite is rebuilding CI for agents: headless APIs, MCP tools, failure you can act on early.

Buildkite is shipping in two directions at once, and both point at automation as the consumer. On the agent side: an MCP server that now waits on builds and summarizes failures in one call, plus broad new REST and GraphQL coverage for pipeline creation, org administration, notification services, hosted agents, and artifacts. On the pipeline side: a checkout block in pipeline YAML that absorbs what previously took Sparse Checkout, Custom Checkout, and Skip Checkout plugins, Test Engine metrics for reliability and duration behind a dated version header, and job logs exportable to an OpenTelemetry collector. Agent v4 becomes stable on 1 September.

5.0

Biome's patch train keeps adding rules — and is quietly growing a Markdown linter.

◆ Current state

Six patch releases since mid-June, each mixing new nursery rules with parser and formatter fixes. 2.5.8 adds useReactCompiler, which surfaces React Compiler's own lint diagnostics through Biome, and makes HTML style attribute values parse as CSS so every CSS rule applies inside them. Framework coverage keeps deepening — Svelte legacy {@const} tags, Vue instance properties, Tailwind arbitrary values — and the JavaScript API package reached 6.0.0 with a byte-to-UTF-16 span helper.

◆ Where it's heading

The rule set is widening along two axes at once: frameworks and file types. Framework rules are now specific enough to argue about Svelte runes rather than generic JavaScript, and CSS handling has pushed into HTML attributes and registered custom properties. The larger move sits in 2.5.8's PR list rather than its changelog — a markdown linter, a markdown rule generator, a markdownlint rule source, a two-phase markdown parser, and a first rule in useTopLevelHeading, none of it documented for users yet.

◆ Prediction

Markdown linting looks close enough to ready that it should appear in the changelog proper rather than the PR list, most likely as nursery rules in the next minor.

Buildkite is rebuilding CI for agents: headless APIs, MCP tools, failure you can act on early.

◆ Current state

Buildkite is shipping in two directions at once, and both point at automation as the consumer. On the agent side: an MCP server that now waits on builds and summarizes failures in one call, plus broad new REST and GraphQL coverage for pipeline creation, org administration, notification services, hosted agents, and artifacts. On the pipeline side: a checkout block in pipeline YAML that absorbs what previously took Sparse Checkout, Custom Checkout, and Skip Checkout plugins, Test Engine metrics for reliability and duration behind a dated version header, and job logs exportable to an OpenTelemetry collector. Agent v4 becomes stable on 1 September.

◆ Where it's heading

The organizing idea is headless CI — every operation that used to require the web UI becoming callable, and every failure becoming legible to something that is not a human reading a log. Promise job failure is the sharpest expression of it: the build lifecycle itself is being reshaped so remediation can start before a job finishes. The versioned API header and the v3-to-v4 stable transition suggest Buildkite is settling its interfaces deliberately rather than accreting them, which is what you do before you expect programmatic clients to depend on them.

◆ Prediction

Expect the MCP server to keep collapsing multi-call workflows into purpose-built tools the way get_build_failure_summary and wait_for_build did, and expect promise-based signalling to extend past failure to other states a long-running job can predict.
