Brace expansion is a utility for expanding brace-delimited patterns, emulating the behavior found in shells like sh and bash. Version 4.0.0 introduces a minor update to this widely-used library, building upon the foundation laid by the previous stable version, 3.0.1. Both versions share a common goal: providing robust brace expansion capabilities for JavaScript environments. Key dependencies remain consistent, with both relying on "balanced-match" (version ^3.0.0) for handling balanced delimiters within the expansion patterns. Development dependencies like "standard" and "@c4312/matcha" also remain the same, indicating a consistent approach to code quality and testing.
The primary difference lies in the internal implementation and potentially bug fixes or performance improvements incorporated into version 4.0.0. Evidenced by a slight increase in fileCount (8 vs. 7) and unpackedSize (12770 vs. 12262), the newer version likely contains small changes or additions to the codebase. For developers, the upgrade to 4.0.0 promises the same core functionality with potential enhancements. As always, reviewing the changelog or release notes associated with version 4.0.0 on the project's repository is recommended to understand precise technical details and impact on existing implementations. The core functionality related to brace expansion remains stable and dependable in both versions.

brace-expansion Regular Expression Denial of Service vulnerability
A vulnerability was found in juliangruber brace-expansion up to 1.1.11/2.0.1/3.0.0/4.0.0. It has been rated as problematic. Affected by this issue is the function expand of the file index.js. The manipulation leads to inefficient regular expression complexity. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 1.1.12, 2.0.2, 3.0.1 and 4.0.1 is able to address this issue. The name of the patch is a5b98a4f30d7813266b221435e1eaaf25a1b0ac5. It is recommended to upgrade the affected component.
