zip.js

• Improve performance when compressing and decompressing files

• Fix onprogress callback when calling ZipEntry#getData() (see https://github.com/gildas-lormeau/zip.js/issues/234)

• Improve memory usage when computing the signature of encrypted files
• Fix minor potential issue when reading zip64 files

• Write the AES extra field in the local header each encrypted entries
• set keepOrder to true by default to avoid generating missing zip64 entries when they are added in parallel

Improve performance of AES encryption/decryption (thanks @xqdoo00o)

• Add the option signal to ZipWriter, ZipReader, ZipWriter#add and Entry#getData which allows you to abort the compression/decompression of a file (see usage examples here and here)
• Add the option dataDescriptor to ZipWriter#add which allows you to include or not the data descriptor record (true by default). Setting it to false will automatically set the option bufferedWrite to true.

Add support for deflate and inflate implementation of fflate, see here for more info on how to integrate it in zip.js.

Improve performances when writing multiple (large) entries in a zip file simultaneously

• Add support of ZipCrypto encryption (option zipCrypto: true when creating a ZipWriter object or calling ZipWriter#add)
• Fix issue leading to a potential invalid entry in a Zip64 file if the compressed file of the entry is larger than the original file and the total size of the zip file is > 4GB
• Fix minor performance issue with transferable objects when using web workers

• Fix issue when reading Zip64 files with appended data at the end of the file and minor issue related to the detection of Zip64 files
• Set type to module in package.json
• Ignore errors that could be thrown by the onprogress callback passed as option

• Add the new option keepOrder to the constructor ZipWriter and the method ZipWriter#add in order to keep ordered the list of files when calling ZipWriter#add multiple times in parallel
• Support reading of zip files with invalid offsets due to data added at the start of the zip file
• Fix issue when calling ZipWriter#add with more than one custom extra field type as option
• Update limit to locate the End Of Central Directory Record at the end of a zip file: 64 KB => 1MB
• Fix detection of unsupported encryption methods (e.g. ZipCrypto) and add a new constant ERR_UNSUPPORTED_ENCRYPTION
• Expose Entry#zip64 to know if a file entry is formatted in Zip64
• Update development dependencies

• Add zip-no-worker-deflate.min.js and zip-no-worker-inflate.min.js in the list of built files in the /dist folder
• Add missing methods to use Uint8Array objects in the Filesystem API
• When adding files in a zip file, auto-detect an entry is a directory if ithe name ends with a "/"
• Minor code improvements

• Fix issue when an FS instance contains imported zip content and FS#export* is called with bufferedWrite set to true
• Minor code improvements

• Add new options to HttpReader and HttpRangeReader (see API doc)
• HttpReader and HttpRangeReader now rely on fetch instead of XMLHTTPRequest by default. This behavior can be changed by setting the option useXHR to true
• HttpReader and HttpRangeReader also accept window.fetch options (when useXHR is not set to true)

• Fix issue when importing the code into a service worker

• Fix issue with the onprogress callback where sometimes the first parameter was always returning 0
• Replace Entry#moveTo() with FS#move(). Entry#moveTo can still be used but is deprecated.
• Add missing ZipFileEntry#replaceData64URImethod
• FS now implements ZipDirectoryEntry
• Add ZipEntry#getRelativeName()
• Add the option relativePath when calling ZipDirectoryEntry.export* methods

• Improve the method ZipDirectoryEntry#addFileSystemEntry added in v2.2.3: it will now return the ZipEntry like other ZipDirectoryEntry#add* functions

• add method ZipDirectoryEntry#addFileSystemEntry to import files or directories from the filesystem into a zip

• Fix type definitions for typescript

• Fix bug if passing a comment as parameter when calling ZipWriter#close()
• Add support of AES-128 and AES-192 encryption (AES-192 encryption is not supported on Chrome currently)
