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 Timely?
Timely is grinding down the friction between tracked time and the tools it has to reconcile with.
Timely ships a steady biweekly changelog centered on three areas: AutoSheet reliability, bulk administrative actions, and integration fidelity with Jira, monday.com, Microsoft Teams, Gmail and Google Calendar. The recent run is corrective and administrative rather than expansive — duplicate client handling on import, undoable CSV imports and bulk moves, project pickers that default to your own work, and repeated fixes to capture gaps in Teams phone calls and high-volume Gmail days.
Biome vs Timely: editorial side-by-side
Biome
5.0INFRA · APIS
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.
Timely
5.0INFRA · APIS
Timely is grinding down the friction between tracked time and the tools it has to reconcile with.
◆ Current state
Timely ships a steady biweekly changelog centered on three areas: AutoSheet reliability, bulk administrative actions, and integration fidelity with Jira, monday.com, Microsoft Teams, Gmail and Google Calendar. The recent run is corrective and administrative rather than expansive — duplicate client handling on import, undoable CSV imports and bulk moves, project pickers that default to your own work, and repeated fixes to capture gaps in Teams phone calls and high-volume Gmail days.
◆ Where it's heading
The product is being hardened for larger workspaces, where the old defaults broke down: full-workspace project lists became unusable, imports collided on names, and a single mis-click across many entries had no path back. Undo is becoming a standard affordance across destructive bulk actions. On the capture side, the recurring theme is that automatic tracking is only as good as its worst integration, and most effort goes to closing the cases where activity silently failed to appear.
◆ Prediction
Expect continued work on integration capture reliability and more bulk operations gaining the same ten-second undo pattern, rather than new tracking surfaces.
