We are excited to announce the official release of Fine Uploader version 5.0.

This is a major version release due to some breaking changes we made to support a great new feature: Concurrent Chunking! This is a feature that other libraries have attempted to implement, without success. Fine Uploader is the ONLY upload library to offer concurrent chunking. This new feature is targeted at applications that expect users to upload single very large files.

Our internal tests that involved uploading multiple chunks for a specific file concurrently showed significant improvements in bandwidth utilization. For example, on our internal network, sending a 110 MB file to S3 with chunk sizes of 5 MB took about 22 seconds when chunks were uploaded one-at-a-time (with concurrent chunking disabled). When maxing out the default maxConnections for that file (3 chunks at once, concurrent chunking enabled) the same file uploaded in about 12 seconds. All other users who tested this feature during the beta phase reported similar results.

You can read more about this new feature on the associated feature page on the docs site.

Other Features:

Support for other promise implementations

This change allows you to use any A+ certified promise impl (such as RSVP or Q) when communicating with Fine Uploader. You may also continue to use Fine Uploader’s own (non-A+-certified) promise implementation.

Dynamically Set Custom Headers

This is targeted specifically at traditional upload endpoints (not S3 or Azure). A new method, setCustomHeaders, has been added to allow you to set upload request headers at any time after the upload instance has been created.

Bug Fixes:

  • Form support parser ignores textarea elements (#1204)
  • Retry Button should remove qq-hide while visible (#1193)
  • File size of 20 bytes is reported for all files in older browsers (#1161)
  • Google Closure Compiler Error (#1163)
  • dataTransfer.items is an object in Chrome and passes the truthy test then throws on the array indexer after && causing a bug (#1166)
  • Total Progress Bar Shows/Hides in rapid succession (#1175)

Next…

As always, for up-to-date information about features and fixes planned for the next release, please see the milestone in the Github issue tracker. At the writing of this post, we are in the process of planning the 5.1 release.

As always, we have continued to add the features that you all demand the most. Thanks again for your continued support. It is due to the backing of commercial license holders, everyone reporting bugs, those who suggest great features, and all the people that have expressed their support for this library that make it as great as it is.

Thanks for being a part of Fine Uploader!
