Acorn is a small, fast, and simple JavaScript parser (ECMAScript parser) library designed for embedding in other projects. Looking at versions 0.7.0 and 0.8.0, both share the same core purpose. They provide tools for projects needing to analyze or manipulate JavaScript code. Crucially, the core dependencies remain constant: regenerate (version ~0.6.2) and unicode-7.0.0 (version ~0.1.5). This suggests the underlying Unicode support and regular expression generation mechanisms used by Acorn remained stable between these releases.
The key difference lies in the release date, with version 0.8.0 arriving roughly a month after 0.7.0 (September 12, 2014 vs August 14, 2014). This difference often indicates improvements in performance, bug fixes, or minor feature additions rather than a complete architectural overhaul. Developers considering upgrading from 0.7.0 to 0.8.0 could likely expect a smoother parsing experience and potentially enhanced support for newer JavaScript syntax features supported at the time. Before upgrading, development teams should consult the changelog/release notes (which are not present in the provided data) for precise details about specific modifications. Because the library focuses on code parsing, changes might be subtle but crucial to specific codebases. Also, the fact that both point to the same source code repository at http://marijnhaverbeke.nl/git/acorn is another guarantee for an API stability.
