4.10.0

[4.10.0] - 2019-07-30

Added:

• In the redis subpackage, the new option DialOptions allows configuration of any connection option supported by Redigo, such as setting a password or enabling TLS. (Thanks, D-Raiser!) Note that it was already possible to specify a password or TLS as part of the Redis URL.
• The new Config property LogUserKeyInErrors, if set to true, causes error log messages that are related to a specific user to include that user's key. This is false by default since user keys could be considered privileged information.

Changed:

• If an error occurs during JSON serialization of user data in analytics events, previously all of the events that were going to be sent to LaunchDarkly at that point would be lost. Such an error could occur if a) the user's map of custom attributes was being modified by another goroutine, causing a concurrent modification panic, or b) a custom attribute value had a custom JSON marshaller that returned an error or caused a panic. The new behavior in these cases is that the SDK will log an error ("An error occurred while processing custom attributes ... the custom attributes for this user have been dropped from analytics data") and continue sending all of the event data except for the custom attributes for that user.
