Release 4.8.0

• Add api_secret parameter to import_data and merge methods. API secret is the new preferred auth mechanism; the old API Key still works but is no longer accessible in the Mixpanel settings UI. (ref: issues #85, #88)
• Add optional verify_cert param to Consumer.init for those having trouble with server cert validation. (ref: issue #86)

Release 4.7.0

• Form $insert_id for track and import calls (if not present) to enable server-side event deduplication.
• Retry API calls upon connection or HTTP 5xx errors. Added new retry options to Consumer classes.
• Replace urllib2 HTTP library with urllib3. This enables connection pooling as well as the aforementioned retries.
• Stop base64 encoding payloads, as Mixpanel APIs now support naked JSON.
• Bug: $time in people operations should be sent in seconds, not milliseconds.

Release 4.6.0

• Add $merge support.
• Support for overriding API host for (say) making calls to EU APIs.
• Updates to $alias documentation.

Release 4.5.0

Add Mixpanel Groups API functionality.

Release 4.0.0
