6.13.0

[6.13.0] - 2020-03-30

Added:

• The new Config parameter initial_reconnect_delay allows customizing of the base retry delay for stream connections (that is, the delay for the first reconnection after a failure; subsequent retries use an exponential backoff).
• The new Config parameter http and the HTTPConfig class allow advanced configuration of the SDK's network behavior, such as specifying a custom certificate authority for connecting to a proxy/gateway that uses a self-signed certificate.

Changed:

• The retry delay for stream connections has been changed as follows: it uses an exponential backoff no matter what type of error occurred (previously, some kinds of errors had a hard-coded 1-second delay), and each delay is reduced by a random jitter of 0-50% rather than 0-100%. Also, if a connection remains active for at least 60 seconds, the backoff is reset to the initial value. This makes the Python SDK's behavior consistent with other LaunchDarkly SDKs.

Deprecated:

• The existing Config properties connect_timeout, read_timeout, and verify_ssl are now deprecated and superseded by the equivalent properties in HTTPConfig.
