Charles Web Debugging Proxy updated to v3.4

Major changes and new features. SSL proxying has been changed to be opt-in per site, rather than on for all sites by default. This is to reduce user problems with Charles’s SSL certificates. Charles also uses a new SSL CA certificate.

Please note that the Charles config file in version 3.4 is not backwards compatible. Charles makes a backup of the 3.3.1 config file when you first start Charles 3.4 in case you need to downgrade.

• SSL Proxying
• Added an explicit list of locations for which SSL proxying will be enabled. You can add to this list by right-clicking on host names in the Structure view.
• Support for client SSL certificates for authentication. See the Client SSL Certificates option in the Proxy menu.
• Setting to use your own SSL CA certificate for Charles to use (PKCS12 format)
