caniuse-lite is a smaller subset of the Can I use (caniuse-db) data, packed to reduce client-side size while keeping essential browser feature information. It provides JavaScript APIs to access browser agents data and to convert feature and region files into formats that are mostly compatible with caniuse-db for use in web-related tooling.
Project status
- Actively maintained: The source (browserslist/caniuse-lite) shows very recent activity, with an upstream push on 2026-07-07, and multiple updates published in the first week of July 2026.
- Apparent update cadence: Updates appear frequent and regular, roughly every few days in late June to early July 2026 (for example 1.0.30001802 on 2026-07-06 and 1.0.30001803 on 2026-07-07).

Recent updates
1.0.30001805
Release 1.0.30001805 has no published release notes. The diff shows changes across 300 files, and they are all data-module updates (module.exports objects) rather than typical application logic changes.
1.0.30001803
Release 1.0.30001803 provides no published release notes. The code diff shows a caniuse-lite version bump that updates the bundled feature data for Shared Web Workers, driven by a dependency update of caniuse-db.
1.0.30001802
Release 1.0.30001802 ships with no publisher release notes. The diff shows two main areas of change: CI/CD workflow logic (how the release job is triggered and published), and extensive updates to the embedded browser/feature support datasets that the package exports.
1.0.30001800
No release notes were provided for version 1.0.30001800. The diff shows CI/CD workflow changes (publishing moved into a new release workflow, action versions bumped) and a large regeneration-style update to browser capability/version datasets under data/ (for many data/features/*.js and data/browserVersions.js).
BreakingSecurity1.0.30001799
Release 1.0.30001799 has no publisher release notes. The diff indicates a large set of data-file updates (300 files changed, equal add/delete counts), most of which are regenerated single-line lookup tables under data/features plus updated agent/version dictionaries.
1.0.30001797
Release 1.0.30001797 does not include any publisher release notes. The code diff shows CI workflow toolchain upgrades (Node and pnpm), plus a large regeneration of browser feature and agent data tables across hundreds of files under data/.
BreakingSecurity1.0.30001793
This release provides no publisher release notes. The code diff indicates a large, mostly mechanical regeneration of compatibility data tables, with many feature-specific datasets and the browser/agent version mappings updated in tandem.
1.0.30001792
Release 1.0.30001792 has no publisher-provided release notes. The code diff instead shows a large regeneration of static data modules, primarily feature-support matrices and browser version mappings, across many files.
Breaking1.0.30001791
Release 1.0.30001791 has no publisher release notes (none provided). The diff shows only a small data update in caniuse-lite’s CSS3 attr feature dataset, plus version bumps to caniuse-lite itself and two upstream data dependencies.
1.0.30001790
Release 1.0.30001790 has no publisher-provided release notes. The diff shows mostly regenerated dataset files (browser version mappings and feature definitions) plus CI workflow and tooling configuration updates.
Security1.0.30001788
This release bumps the caniuse-lite package version from 1.0.30001787 to 1.0.30001788. The only actual code diff changes update underlying data dependencies, specifically caniuse-db and @mdn/browser-compat-data, via package.json and pnpm-lock.yaml.
1.0.30001787
Release 1.0.30001787 has no publisher release notes (none provided). The diff is entirely dominated by updates to precomputed data tables under data/, with no visible runtime code changes or API surface edits in the provided diff.
1.0.30001786
Release 1.0.30001786 contains no publisher-provided release notes. The code diff indicates this version mainly regenerates caniuse-lite feature data from a newer caniuse-db release, updating browser compatibility mappings for a small set of features.
1.0.30001785
Release 1.0.30001785 does not include any published release notes (none provided). The code diff shows only version and dependency updates, specifically bumping caniuse-db and @mdn/browser-compat-data versions used by this package.
1.0.30001784
Release 1.0.30001784 was published on 2026-04-01, but the publisher did not provide any release notes. As a result, this release cannot be assessed for new features, breaking changes, bug fixes, security updates, performance improvements, migrations, or dependency changes from the provided information.
v1.0.30001224
v1.0.30001224 appears to be primarily a regeneration of the bundled caniuse-lite dataset (large data file updates) plus some repository-level maintenance changes (CI workflows, documentation trimming, and build config cleanup). No release notes were provided by the publisher, so the changes below represent what is visible in the diff rather than what was documented.
v1.0.30001223
This release increments the caniuse-lite package version and updates its bundled caniuse data by bumping the underlying caniuse-db dependency. No release notes were provided, so the only concrete changes are the version and data updates reflected in the repository diff.
v1.0.30001222
No release notes were provided for v1.0.30001222, so changes cannot be identified from the published text. Developers should review the corresponding GitHub commit diff and tagged release contents to detect any functional, API, or configuration changes before upgrading.
v1.0.30001221
No release notes were provided for v1.0.30001221. The code diff indicates this release primarily updates generated data files, including the top-level agents dataset and many per-region datasets, by replacing numeric values used for downstream calculations or lookups.
v1.0.30001220
Release v1.0.30001220 bumps the embedded dataset by updating the caniuse-db dependency and regenerating several feature definition files. The diff shows only data and dependency changes (no runtime logic or API surface changes in this diff). Release notes were not provided, so changes to browser-feature mappings are not documented.
