Babylon versions 6.3.20 and 6.3.21, both JavaScript parsers from the Babel project, share nearly identical characteristics with a few notable distinctions. Both are licensed under the MIT license and feature babel-runtime as a runtime dependency and babel-helper-fixtures as a development dependency. The core functionality, described as parsing JavaScript, remains consistent across both versions. The source code repository also remains the same.
The most significant difference lies in their release dates. Version 6.3.21 was published on December 18, 2015, while version 6.3.20 came out two days earlier on December 16, 2015. Given the proximity in release dates, the changes are likely minor bug fixes, performance improvements, or very specific edge case handling within the parsing logic.
For developers using Babylon, upgrading from 6.3.20 to 6.3.21 is typically recommended to benefit from any bug fixes or incremental improvements made. However, due to the small increment in version number and the lack of documented breaking changes (implied by the identical dependencies), the upgrade should be relatively straightforward with minimal risk of introducing compatibility issues. Before upgrading, developers should be aware of what was changed between those versions to evaluate if the changes are important to them.
