According to ITWire article:

Specific changes called out by Apple are a fix for an issue that could cause the search and address field to load a webpage or send a search term before the return key is pressed, support for generic top-level domains (so that Safari loads the requested page instead of treating it as a search term), and strengthened Safari sandboxing.

Very important update.
