Only affecting rust sdk: StatsigUser data has moved one level deeper to StatsigUserData This change means:

⚠️ Important Changes

Only affecting rust sdk: StatsigUser data has moved one level deeper to StatsigUserData This change means:

To create more complex StatsigUser, need to create StatsigUserData. StatsigUser only expose with customID and withUserID
Instead of serializing and deserializing StatsigUser, now need to serialize StatsigUserData.
Use StatsigUserBuilder to create StatsigUser objects:

let user = StatsigUserBuilder::new_with_user_id("user-123".to_string())
    .email(Some("user@example.com".to_string()))
    .ip(Some("192.168.1.1".to_string()))
    .user_agent(Some("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36".to_string()))
    .country(Some("US".to_string()))
    .locale(Some("en-US".to_string()))
    .app_version(Some("1.0.0".to_string()))
    .custom_ids(Some(custom_ids))
    .custom(Some(custom_attributes))
    .private_attributes(Some(private_attributes))
    .build();

New Features

spec_source_api tag in emitted metrics
custom output logger in rust + python
initialize with details in java

Improvements

performance improvement
supports java 8

0.2.016 Apr 2025

> UA parser and Ip3 country lookup packages now load lazily by default.

⚠️ Important Changes

UA parser and Ip3 country lookup packages now load lazily by default.

enableUserAgentParsing and enableCountryLookup have been removed from statsigOptions.

If you would like to wait for it during initialize, use waitForUserAgentParsingInit / waitForCountryLookupInit in statsigOptions. Or you can also disable these two packages with disableUserCountry / disableUserAgent.

Event flushing now controls the QPS internally.

You can adjust event throughput with event_logging_max_pending_batch_queue_size and event_logging_max_queue_size options. In stable server environment, the internal QPS is generally more than enough, but if used in scripts environment where a high volume of config checks are happening in a short burst, the sdk may hit its internal buffer limit after which additional events may be dropped. For running scripts/known burst traffic, increase event_logging_max_queue_size so the SDK can hold onto all events for the duration of the run. For more information, see our docs here: https://docs.statsig.com/sdk/debugging/#maximizing-event-throughput

New Features

Core[Internal]: smart log event. new statsig options to tune event logging throughput
Python: Persistent storage

Improvements

Core[Internal]: performance improvement
Core: reduced spammy logs
