• Editor: New Edit->Find in All Open Documents option. This option will go to the first open document and begin the search. It will proceed through the open documents to the last document and then stop searching. Search will also stop if a match is found. You can then use F3 to continue the search and find the next match. At the end of the search it will automatically select the document that was originally active so you end up back in the same document from where you started.
• Batch Wizard: The Limit to text now accepts wildcards for the protocol

• Validator: Updates and improvements to both the HTML and CSS checking engines
• Validator: Updates to the JavaScript linters
• Improved handling of updates and checking for updates. If the option to do so is set (it is by default), then CSS HTML Validator will periodically and silently check for updates in the background without asking first. It should only display a dialog if the 'out-of-date' flag is sent by the server. The status bar may show some activity if the update check is performed but the user should not be interrupted unless it's important enough. See forum post: Check for updates dialog
