The buffer module provides the Node.js `Buffer` API for use in the browser, including compatibility with `Buffer` global usage via browserify (`require('buffer')`). It is useful when you need to manipulate binary data in browser code while keeping the same methods and behavior as Node's `Buffer` API.
Project status
- This GitHub source (feross/buffer) shows a long gap in the provided update history, with the newest listed update in late 2020 (v6.0.3), while the last upstream push is 2025-10-28. Based on the available evidence, there is not enough recent update activity to call it actively maintained, it looks quiet/dormant with respect to the last several years.
- The apparent update cadence is bursty rather than regular: several updates cluster in 2020 (roughly weekly to biweekly around v5.7.x to v6.0.2), then there is no documented activity in the provided recent summaries for ~5 years.

Recent updates
v6.0.3
Release v6.0.3 contains no provided release notes. The diff shows only a version bump plus updates to TypeScript declaration signatures in index.d.ts, along with an AUTHORS.md entry.
v6.0.2
Release v6.0.2 includes a version bump and updates the TypeScript type definitions for the Buffer API. The only code-related change shown in the diff is that BigInt-based Buffer read and write methods were added to index.d.ts.
Featuresv6.0.1
This is a patch release (v6.0.1) but no release notes were provided by the publisher, so the changes are not described. As a result, there is no documented information here about new features, fixes, security updates, or migration requirements.
v5.7.1
v5.7.1 is a small maintenance release (version bump from 5.7.0) with a focused change to Buffer.concat behavior when concatenating Uint8Array inputs with a provided totalLength. The release notes section contains no documented changes.
v6.0.0
Release v6.0.0 has no publisher-provided release notes. The diff shows a mix of internal code refactors (var to const/let), dependency version bumps, test and build script renames, browser test matrix updates, and an added test covering Buffer BigInt64 and BigUInt64 read/write behavior.
BreakingFeaturesv5.7.0
Release v5.7.0 introduces internal Buffer implementation changes around typed array handling and UTF-16LE slicing, plus a set of new alias methods (readUint*). Release notes were not provided, so all behavioral and API-relevant changes below are based on the actual code diff between v5.6.2 and v5.7.0.
BreakingFeaturesv5.6.2
Release v5.6.2 contains minimal code changes: an internal refactor in Buffer.prototype.write related to the 'latin1'/'binary' encoding handling, plus non-code metadata updates. The provided release notes are empty, so any behavioral impact must be inferred from the diff itself.
v5.6.1
Release v5.6.1 (no publisher release notes provided) makes a small internal change in the utf8Slice logic, updates dependency versions in package.json, and adjusts a single test expectation. The diff does not show any API surface changes in the production code beyond dependency bumps.
v5.6.0
Release v5.6.0 contains a version bump and a small code change in the Buffer implementation. No release notes were provided, so the only behavioral signal comes from the code diff, which removes an ES2016 subarray workaround.
v5.5.0
Release v5.5.0 was published on 2020-03-06, but the publisher did not provide any release notes. No details are available here about new features, bug fixes, security updates, breaking changes, or migration steps.
