  • When updates to older versions released, updates will be done in two steps, after you have updated, you will see another alert for 2nd update.

  • Improved detection of untrusted certificates. In last release we introduced Untrusted Certificate scan in Rating scan. But it could show legit certificate also. In this release we have updated logic and we can avoid showing known trusted certificate as untrusted as stated here. e.g. In this release, you won't see false-detection as reported here. That's the only one exception for now. Please report if you have any legit cases detected and we can put that in exclusion list.
