We are happy to announce the release of the latest major CKEditor version. CKEditor 4.7 comes with plenty of new features - including Paste from Excel support, advanced table selection, improved conformance with Content Security Policy, and further enhancements to the pasting process. In addition to that, some important changes were introduced to popular plugins such as Media Embed, Copy Formatting, and Mathematical Formulas. Read on for more!
Advanced table selection
Table support has always been an important feature for CKEditor users and with time (and also, with the number of issues that came from different browsers implementing table selection differently) we have decided to work on a custom implementation that would help us deliver an outstanding user experience when handling tables. Starting from CKEditor 4.7 you can now use the unique custom selection system for tables to, for example:
- Select an arbitrary rectangular table fragment - a few cells from different rows, a column (or a few of them) or a row (or multiple rows).
- Apply formatting or add a link to all selected cells at once.
- Cut, copy and paste entire rows or columns.
Creating a custom selection system meant that we needed to rewrite some core editor parts to bring support for multiple ranges for tables (and only tables) and integrate it with clipboard to make sure that only the selected table fragment is copied or pasted. The new system was obviously integrated with the existing plugins such as Table Tools, styles or links.
Content Security Policy support
CKEditor 4.7 brings improved compliance with CSP with the removal of dynamic evaluation calls in the template system. Thanks to this, the editor can now be used without
unsafe-eval in the Content Security Policy. We would like to thank Caridy Patiño for proposing a solution to this challenge!
Paste from Excel
Thanks to some further enhancements in the Paste from Word plugin CKEditor is now able to reliably support basic Excel formatting, too. Styles such as table cell background color and height or font styles (color, family, weight, size etc.) will be copied to preserve the original Excel formatting.
Advanced Paste from Word updates
Thanks to some enhancements in the Paste from Word plugin the editor is now able to retain formatting applied using Word’s defined style rules in all browsers that support clipboard data transfer. This lets the editor copy and paste inline styles that were previously shown in CKEditor as unformatted text.
Last but not least, further updates to the paste engine were introduced to improve the editor behavior with pasting lists, whitespaces, images, paragraphs looking like lists and similar edge cases - which only shows the huge complexity of all scenarios that the Paste from Word feature needs to support in multiple environments and browsers.
Mathematical Formulas CDN change
Media Embed change
config.embed_provider configuration option for the Media Embed and Semantic Media Embed plugins is no longer preset by default - you will now need to set it manually when configuring the plugins. The ready-to-use provider URL is still available; however, it is most recommended to register a custom Iframely account to gain access to some features such as Google Maps API. More details here.
Further paste improvements
We have decided to simplify the user experience when pasting and said goodbye to the old paste dialog window. From now on, the editor behavior on pasting will be unified and the user will be prompted to paste the content using an appropriate keyboard shortcut when the browser blocks it due to security settings. Furthermore, a few other issues with Paste as Plain Text were fixed.
Additionally, with recent Safari fixes it is finally possible to use enhanced clipboard API (introduced in CKEditor 4.5) also in this browser. This will result in improved HTML pasting experience, including the Paste from Word feature.
