Version 5.0.0

Major

• extractFiles has a new return signature and no longer mutates the original input, fixing #8. It returns an object with clone, a clone of the original input value with files recursively replaced with null, and files, a Map instance keying each extracted file to an array of object paths.

Minor

• Files can now be used as the root value passed to extractFiles.

Patch

• Updated dev dependencies.
• Updated package description.
• Moved JSDoc type definitions into the index file.
• Manually composed package exports instead of relying on *.
• Improved tests.
• Added a paragraph explaining the GraphQL use case to the readme.
