Webpack version 0.2.4 arrived swiftly after version 0.2.3, both iterations packing CommonJs modules for browser environments and offering code splitting capabilities for on-demand loading of bundles. Examining the package data reveals a minimal incremental update, as the core functionality and dependencies---esprima, sprintf, optimist, and uglify-js---remain identical across both versions. The devDependencies, namely vows, also remain consistent, suggesting no changes to the testing framework.
The most notable difference lies in the release date, with version 0.2.4 being published just hours after 0.2.3. This rapid succession implies that 0.2.4 likely addresses a bug fix or minor enhancement discovered immediately after the initial release of 0.2.3. For developers, While there are no listed changes that can be seen from the package data, the immediate release of version 0.2.4 suggests a potential critical fix or subtle improvement over 0.2.3. Therefore, it is recommended to choose the latest 0.2.4, as it is the newest and presumably most stable version.

var result = "";
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
u.parse("var a = " + genstr(process.argv[2], "1") + ".1ee7;");
