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 mod_auth_openidc?

mod_auth_openidc audited itself, found eight holes, and broke every session on the way out

The Apache OIDC module is in the middle of the most consequential ten days in this window: 2.4.20 on August 1 rebuilt session and cookie encryption around PBKDF2-HMAC-SHA256 key stretching and invalidated every existing session, 2.4.20.1 on August 9 disclosed eight security issues found in an internal audit, and 2.4.20.2 the next morning walked back part of the fallout. The audit findings are not peripheral — the most serious lets a client inject headers that a protected backend trusts as authenticated identity claims on paths the module answers without authenticating. The 2.4.19.x line before it had already shipped an out-of-bounds read and write in the state-cookie parser.

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.

mod_auth_openidc audited itself, found eight holes, and broke every session on the way out

◆ Current state

The Apache OIDC module is in the middle of the most consequential ten days in this window: 2.4.20 on August 1 rebuilt session and cookie encryption around PBKDF2-HMAC-SHA256 key stretching and invalidated every existing session, 2.4.20.1 on August 9 disclosed eight security issues found in an internal audit, and 2.4.20.2 the next morning walked back part of the fallout. The audit findings are not peripheral — the most serious lets a client inject headers that a protected backend trusts as authenticated identity claims on paths the module answers without authenticating. The 2.4.19.x line before it had already shipped an out-of-bounds read and write in the state-cookie parser.

◆ Where it's heading

The project has shifted from feature work to hardening its own attack surface, and it is doing so on its own initiative rather than in response to external reports. That posture has a cost operators are absorbing directly: two backwards-incompatible session format changes in six months, both of which log every user out on upgrade. The 2.4.20.2 release also shows the hardening overshooting and being corrected — unconditional secret masking made debugging impossible, so an opt-in escape hatch was added with a startup warning attached, and a derived-object cache tier added only weeks earlier was removed outright.

◆ Prediction

Expect the 2.4.20.x line to keep absorbing follow-up fixes from the same audit, and any further hardening to arrive with an explicit opt-out after the masking reversal showed operators cannot troubleshoot a protocol exchange they cannot read.
