-If you already use SDK v1 or v2, it is strongly suggested migrate to v3 as we refactor the implementation to make it simpler and easy to maintain. We will stop the maintenance of v2 in the near future. Please refer to the instruction on how to migrate v1 or v2 to v3 in section [Migrate from v1 or v2](#Migrate-from-v1)
+If you already use SDK v1 or v2, it is strongly suggested migrate to v3 as we refactor the implementation to make it simpler and easy to maintain. The SDK v3 is completely consistent with the API documentation of the new HTX open platform. Compared to SDK versions v1 and v2, due to changes in parameters of many interfaces, in order to match the latest interface parameter situation, v3 version has made adjustments to parameters of more than 80 interfaces to ensure that requests can be correctly initiated and accurate response data can be obtained. Meanwhile, the v3 version has added over 130 new interfaces available for use, greatly expanding the number of available interfaces. We will stop the maintenance of v2 in the near future. Please refer to the instruction on how to migrate v1 or v2 to v3 in section [Migrate from v1 or v2](#Migrate-from-v1-or-v2)
