It was time for the 3.5 branch to go from beta to a production release. The 3.5 version includes HTML5 support, style preview support, rewritten noneditable plugin, selection and caret behavior changes/fixes, new enter/return logic and much more check the changelog for details.

This is also the first official release of the NuGet packages for TinyMCE.

Thanks for all bug reports and help with testing out the beta versions.

Here are some more details on whats in the 3.5 release:

Rewritten noneditable plugin
We decided to rewrite the noneditable plugin from scratch since the old one had some issues with nested editable contents and was a bit tricky to use. The new logic makes it easier to handle nested editable regions and inline noneditable blocks of text like variables/placeholders.

Here is a demo of the new noneditable plugin:

HTML5 support and visualblocks plugin
We have seen some feedback on subject of editing HTML5 contents inside TinyMCE so we decided to add support for editing the block level HTML5 elements like section and article etc.

We needed to create a visualblocks plugin in order to edit these new block types since it would be difficult without having visible guidelines where the blocks start/end.

Here is a demo of the visualblocks plugin and a config setup for editing HTML5.

Styles preview
A common request over the years have been to have a preview of the styles in the styles drop down. The common response we had before was that it would be difficult since some CSS properties of these styles might interfere with the UI. We solved this by only taking CSS properties that alter text appearance and not the once that might break layout.

New br_in_pre option
This option is enabled by default and changes the behavior on how the enter key is used within a pre tag. Since most pre tags are used for things like code examples like on our Wiki it made more sense to produce a BR on enter by default and only split pre tags when hitting shift+enter. If you don't want this new behavior you can set the br_in_pre to false.

BR vs P
I've seen a lot of requests over the years to have better support for producing BR elements by default in the editor. And I have always tried to explain why paragraphs is better than br:s.

But guess what I got some news for you BR fan boys out there this version now fully supports BR elements and things like alignment and indentation work it will auto generate a div if you don't have any block element to align or indent.

The force_br_newlines/force_p_newlines where removed since it doesn't make sense to mix the forced_root_block option with that. So just set forced_root_block to false and it will start spitting out those pesky BR elements.

If you want to split a block element while having forced_root_block set to false you would have to press shift+enter since enter will insert a BR within the block. We might add some option to control this as well in the future.
