CKEditor 3.5.2 Released!

Welcome to the past! 👻
Unfortunately, CKEditor 3 is no longer with us. RIP ❤️

Instead, you can check our new and powerful rich text editor framework, CKEditor 5. It has a modular architecture, integrations with popular JavaScript frameworks and features like real-time collaborative editing.

Or, you can discover CKEditor 4, which is an enterprise-grade WYSIWYG editor with countless features and wide browser compatibility including the legacy ones.

Take me to the future ✨

We would like to announce the latest release of CKEditor. CKEditor 3.5.2 is a maintenance release for the CKEditor 3.x line. It is a special Internet Explorer 9 RC compatibility release containing a handful of fixes that should improve the editor support in the freshest edition of Microsoft browser.

Internet Explorer 9 RC Compatibility

Internet Explorer 9 Release Candidate was published on February 10, 2011 and we have decided to provide a special CKEditor release for the users who would like to evaluate the editor performance in this browser. Due to the bug in implementation of the JavaScript do... while statement on Microsoft side, CKEditor was blocked from displaying in the browser. Do remember that as any other Beta or Release Candidate product, IE9 RC is not a stable release and in general, should be used with care, for evaluation purposes only. Other bugs may still occur and be fixed by Microsoft before the final release of the product.

Optional Upgrade

Please note that this is a dedicated CKEditor release which is based on CKEditor 3.5.1 with only a couple of fixes aimed at supporting IE9 RC, so we encourage to upgrade only if you need CKEditor to work with the latest Microsoft offer. Since the Release Candidate product may slightly differ from the final release, we will test CKEditor and provide full Internet Explorer 9 support after the browser is released to the public.
