Important Notes:

• Dropped compatibility support for Internet Explorer 7 and Firefox 3.6.
• Both the Basic and the Standard distribution packages will not contain the new Indent Block plugin. Because of this the Advanced Content Filter might remove block indentations from existing contents. If you want to prevent this, either add an appropriate ACF rule to your filter or create a custom build based on the Basic/Standard package and add the Indent Block plugin in CKBuilder.
