Differences Between the Basic Edition and the Enhanced Edition

• SDK added the Enhanced Edition from SDK 5.4. The original edition is called the Basic Edition.
• Both the Basic Edition and Enhanced Edition support V2 APIs. However, the Enhanced Edition no longer supports legacy APIs while the Basic Edition still supports legacy APIs.
• If you have not integrated legacy APIs, we recommend that you directly use V2 APIs and choose the Enhanced Edition SDK.
• If you have integrated legacy APIs, we recommend that you upgrade to V2 APIs and gradually transition to the Enhanced Edition SDK.
• Compared with the Basic Edition, the Enhanced Edition has greatly reduced the SDK size and installation package increment.
• Compared with the Basic Edition, the Enhanced Edition provides more new features.
• Subsequent development of new features will only be supported on the Enhanced Edition. The Basic Edition supports only routine maintenance and fixing of existing problems.
• Enhanced Edition Pro has been released from SDK 6.8 version which supports dual line acceleration on network layer and provides better performance for bad network environment.
