Note

The AWS Neuron SDK is updated regularly with new versions. These releases follow a semantic versioning model of (major).(minor).(patch). major versions are more likely to introduce new features and breaking changes over a prior major version. minor versions add feature and API improvements and may introduce smaller breaking changes. patch versions typically provide bug fixes and will not have breaking changes.
