Topic: TinyMCE 4.2.5 released
This release includes some important bug fixes so we recommend everyone using the 4.2.x branch to update to this release.
The most important bug fix is around performance issues with navigation though tables that could result in the browser freezing. We also fixed an issue with IE 10 and the new uploadImages API method where it wouldn't properly upload files.
The release also includes a bunch of performance fixes around the Image Upload API such as uploading files in parallel and caching Promise/callbacks responses.
