• Consolidate metadata types and expose OnUpdateCallback #851 and #852
• use const instead var in example from README.markdown #828
• Switch manual download link to HTTPS #839

Internals:

• Replace jshint with eslint #842
• Add performance tests #834

v3.10.0 2022-05-20

• Change setimmediate dependency to more efficient one. Fixes https://github.com/Stuk/jszip/issues/617 (see #829)
• Update types of currentFile metadata to include null (see #826)

v3.9.1 2022-04-06

• Fix recursive definition of InputFileFormat introduced in 3.9.0.

v3.9.0 2022-04-04

• Update types JSZip#loadAsync to accept a promise for data, and remove arguments from new JSZip() (see #752)
• Update types for compressionOptions to JSZipFileOptions and JSZipGeneratorOptions (see #722)
• Add types for generateInternalStream (see #774)

v3.8.0 2022-03-30

• Santize filenames when files are loaded with loadAsync, to avoid "zip slip" attacks. The original filename is available on each zip entry as unsafeOriginalName. See the documentation. Many thanks to McCaulay Hudson for reporting.

v3.7.1 2021-08-05

• Fix build of dist files.
  • Note: this version ensures the changes from 3.7.0 are actually included in the dist files. Thanks to Evan W for reporting.

v3.7.0 2021-07-23

• Fix: Use a null prototype object for this.files (see #766)
  • This change might break existing code if it uses prototype methods on the .files property of a zip object, for example zip.files.toString(). This approach is taken to prevent files in the zip overriding object methods that would exist on a normal object.

v3.6.0 2021-02-09

• Fix: redirect main to dist on browsers (see #742)
• Fix duplicate require DataLengthProbe, utils (see #734)
• Fix small error in read_zip.md (see #703)
