Changelog

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 ‘End of data reached’ error when file extra field is invalid (see #544).
  • Typescript definitions: Add null to return types of functions that may return null (see #669).
