Version 4.13 is vulnerable to a man in the middle attack during login. The security hole requires a targeted attack to exploit. The risk assessment is low. The attacker may capture the session cookie and the encrypted password. Upgrading to 4.14 is highly recommended.
Google changed the app search protocol again, resulting in Raccoon v4.10 (and earlier) showing non app items for certain search terms. These are filtered away now.
