Up until the most recent Chrome release, the browser had four different security badges it displayed in the URL bar: secure HTTPS, HTTP, HTTPS with minor errors and Broken HTTPS. Starting with the latest Chrome release, version 46, the yellow caution triangle indicating HTTPS with minor errors will be removed to simplify the system of security badges. This state will now marked with the same page icon as standard HTTP pages. 

According to Google’s blog post, ”This change is a better visual indication of the security state of the page relative to HTTP” and ensures that “Chrome users will have fewer security states to learn.” Additionally, the change is intended to encourage website operators to migrate to the more secure HTTPS protocol. Previously, if a site owner was in the midst of a migration from HTTP to HTTPS content their website would receive the aforementioned mixed content security warning badge. “Removing the yellow “caution triangle” badge means that most users will not perceive a warning on mixed content pages during such a migration.” In the future Chrome is likely to move to a two-badge system to indicate a website’s security, which will be deemed either "secure" or "not secure."
