Version 7.13.15 of @babel/core, released on April 8, 2021, introduces several dependency updates compared to version 7.13.14, released on March 29, 2021. Key changes for developers include an updated @babel/parser (from 7.13.13 to 7.13.15) and @babel/traverse (from 7.13.13 to 7.13.15), potentially incorporating bug fixes and performance enhancements in parsing and AST traversal. Additionally, there are updates to packages such as @babel/types, and @babel/generator.
Also there is an update in the devDependencies section for the library where the new @types/debug, @types/lodash, @types/semver, @types/resolve, @types/source-map, and @types/convert-source-map where added.
The core functionality of Babel, like compiling JavaScript, remains consistent. Developers should evaluate the updated dependencies for any specific impact on their build processes or code compatibility. Specifically, those relying on advanced parsing features or AST manipulation should review the @babel/parser and @babel/traverse changelogs for relevant fixes or changes. The unpacked size has slightly increased to 183178, so might have to take into account the bundle size of the new javascript files built with this new version. The newer version ensures compatibility and takes advantage of the latest tooling and fixes within these core Babel components, although the differences look like improvements of the inner functionalities more related to the infrastructure of the package.
