Release Notes

Stuk/jszip

v3.7.0

Compare Source

• 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

Compare Source

• 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)

v3.5.0

Compare Source

• 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).
• Typescript definitions: Correct nodeStream's type (see #​682)
• Typescript definitions: Add string output type (see #​666)

v3.4.0

Compare Source
