## 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](https://intl.cloud.tencent.com/document/product/1047/36169). 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](https://intl.cloud.tencent.com/document/product/1047/36169) and choose the Enhanced Edition SDK.
- If you have integrated legacy APIs, we recommend that you upgrade to [V2 APIs](https://intl.cloud.tencent.com/document/product/1047/36169) 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.
