Migrating from 3.3.7 to 3.4.0

Enum technical values cleanup 

We removed *Unrecognized and *Unspecified values from all enumerations. These were technical values for internal use.

For a limited number of enums where the Chromium counterpart has an unknown state, we added Unknown values:

• PermissionType.Unknown
• CreditCardNetwork.Unknown
• RequestStatus.Unknown
• NetError.Unknown
• SuggestionsPopupType.Unknown
• ColorModel.Unknown
• DuplexMode.Unknown

Where applicable, replace removed values with the new Unknown value.

Removed NetError values 

We removed certain NetError enum values that no longer exist in Chromium. If your code references any of these values, you will see compilation errors indicating which specific values are no longer available:

• NoSslVersionsEnabled
• HttpsProxyTunnelResponse
• SslHandshakeNotCompleted
• SslBadPeerPublicKey
• SynReplyNotReceived
• EncodingConversionFailed
• UnrecognizedFtpDirectoryListingFormat
