UPDATE
JCE 2.5.1 has been released to fix a bug where some elements, eg: <em>, <i> were removed if they had no attributes.
JCE 2.5.0 "Stable" has been released. This update includes a number of changes and bug fixes. Thank you to everyone who tested the Beta and Release Candidate versions.
Changes to core file packaging
Some time ago we introduced a method to combine and compress the editor's javascript and css files, resulting in a single javascript or css file for the browser to download. This generally results in improved load performance, as the browser only has to download one file.
Some users have found, and reported, that for some reason or other, this feature does not work on their site, or they choose not to use it. We have therefore done some of this combining when the extension is packaged, resulting in fewer javascript and css files in the extension, and therefore fewer files to load by the editor and add-ons.
Enabling the compression options will still combine these files into a single javascript and css file.
New Features
Three new features have been added in this release:
Form Elements for Custom Styles
It is now possible to create a Custom Style with a form, input, button, fieldset or legend tag.
Total Files and Total File Size limits
You can set the total number of files the File Directory Path (and its subfolders) can contain, as well as the total size of this folder in Editor Profiles -> Editor Parameters -> Filesystem. This restriction is applied when the user uploads a file.
"Mixed" Doctype
A "Mixed" Doctype option is available in the Editor Global Configuration and is the default setting on new installs. This option sets the HTML schema the editor uses to included HTML4 and HTML5 elements and attributes.
