No changes. The stabilization of the 2.6 RC was completed successfully, as expected.

New Features and Improvements:

• [#35] New (and cool!) floating dialog system, avoiding problems with popup blockers and enhancing the editor usability.
• [#1886] Adobe AIR compatibility.
• [#123] Full support for document.domain with automatic domain detection.
• [#1622] New inline CSS cache feature, making it possible to avoid downloading the CSS files for the editing area and skins. For that, it is enough to set the EditorAreaCSS, SkinEditorCSS and SkinDialogCSS to string values in the format "/absolute/path/for/urls/|<minified CSS styles". All internal CSS links are already using this feature.
• New language file for Canadian French.
