Version 7.12.0 of @babel/core brings several crucial updates compared to its predecessor, 7.11.6, enhancing Babel's core compilation capabilities. Developers upgrading will notice updates in several core dependencies. Specifically, @babel/types, @babel/parser, @babel/traverse, @babel/generator, and @babel/helper-module-transforms have all been bumped to version 7.12.0 suggesting a focus on improvements and fixes within Babel's abstract syntax tree (AST) handling, code parsing, tree traversal algorithms, code generation, and module transformation utilities, respectively.
It's important to note that @babel/helpers and @babel/template remain unchanged, retaining version 7.10.4, as well as @babel/code-frame meaning no new features or breaking change around those parts of the library.
The developer tooling also sees improvement: @babel/helper-transform-fixture-test-runner moves to version 7.12.0. This update likely provides a better testing and fixture management experience for Babel plugin authors.
The updated dist metadata shows a slight increase in both the fileCount (from 49 to 53) and the unpackedSize (from 162506 to 171035 bytes), indicating added features, bug fixes, or optimization within the core package. The release date also highlights the recency of version 7.12.0, released on October 14, 2020, compared to version 7.11.6 released in early September, reflecting ongoing development and refinement.
