We are happy to announce the release of CKEditor 4.5.2. This is a minor bug fixing version whose primary focus is to improve compatibility with Microsoft Edge, the new Windows 10 browser that has just been published. Apart from Edge fixes, a few notable issues in other browsers were also corrected and some improvements were brought to the new features introduced in CKEditor 4.5, including drag&drop, embedding media resources with oEmbed, nested widgets and the toolbar configurator.
Microsoft Edge, officially released on July 29, 2015, was at the heart of this editor release. The CKEditor team was actually working hard on Edge compatibility since the early preview versions of this browser and has already logged quite a few tickets to the browser vendor. Meanwhile, we tried to patch whatever we could on our side to ensure all CKEditor users will get the high quality experience they are accustomed to. Among the fixed issues were various “permission denied” errors or browser crashes when switching from source mode to WYSIWYG. The latter issue was actually debugged and fixed by Andrew Williams and Mark Smeed — another example, alongside a recent fix for the new toolbar configurator submitted by Colemanw, of the great editor community stepping up and giving us a hand!
Apart from Edge problems, this release also fixes a few issues in other browsers, including a critical fix for Firefox for broken paste from Microsoft Word and other external applications or a broken paste from Microsoft Excel and few other improvements for Chrome.
New Features Improved
Our last major release, CKEditor 4.5, introduced a slew of innovative features like drag&drop uploads, embedding media resources, support for nesting widgets, notification system and toolbar configurator. CKEditor 4.5.2 includes lots of improvements for how these new pieces of editor functionality work and how they are integrated with one another.
