Breaking changes:
1. The minimum version requirement for ClairView servers is now 1.38. If you're using ClairView Cloud, you satisfy this requirement automatically.
2. Feature flag defaults apply only when there's an error fetching feature flag results. Earlier, if the default was set to `True`, even if a flag resolved to `False`, the default would override this.
**Note: These are removed in 2.0.2**
3. Feature flag remote evaluation doesn't require a personal API key.
New Changes:
1. You can now evaluate feature flags locally (i.e. without sending a request to your ClairView servers) by setting a personal API key, and passing in groups and person properties to `is_feature_enabled` and `get_feature_flag` calls.
2. Introduces a `get_all_flags` method that returns all feature flags. This is useful for when you want to seed your frontend with some initial flags, given a user ID.
