- Fix not being able to resize detached blob (created from dataUrl or binary string) that was added via uploader.addFile().
- Consider HTTP status below 200 an error as well (mostly because when connection breaks, HTTP status might be reported as 0).
- Do not set inner global xhr var to null onloadend of any single instance (which caused random errors during the upload).
- Expose whole moxie namespace under `plupload.moxie` (mostly for smooth integration into environments like Webpack).
- Add new filter prevent_empty, which filters out empty files by default, but can be turned off if required.
- Update Russian, Latvian and German language packs.
- Update mOxie to: v1.5.5.
