– Implemented a Hive-based backup synchronization mechanism
– Improved Trinity cli to support publishing dApp to Hive Vault
– Improved Wallet cross-device synchronization/recovery mechanism and implementation
– Improved the handling of transaction fees in wallet transfers where the wallet will automatically calculate and add to the transfer amount
– Fixed the issue of Wallet ERC token transfer
– Added video capture/editing plugin
– Improved import DID and synchronized UI/UX
– Added dApp debugging information to Sentry to facilitate user problem location and debugging
– Improved multilingual resources
– Improved the implementation of Runtime for iOS and Trinity Native
– Fixed elastOS Essentials iOS issues reported by the community

DID
– Continued to discuss the DID v2.0 version specification definition and implementation plan
– Custom short name DID supported in DID Native SDK, and supplemented test case verification
– Solved the problem of compatibility between the metadata format in the new DID SDK and the original DID SDK
– Continued to develop Customized DID of DID Native SDK to support multiple Controllers
– Optimized the DID Swifft SDK, provided the Object-C language version of the interface set, and provided the corresponding Object-C interface document generation

Hive
– Released a new internal test version alpha-v2.0.2 on front-end Java SDK for third-party application development and verification
– Released an internal test version for Hive node and updated and deployed Hive Node service nodes for third-party application development and verification
– Discussed the backup/restore Vault scheme of the back-end Hive Node, including the lifecycle interface design of Vault, and planned the features that need to be implemented in the first step
– The front-end Java SDK Supported file upload/download on front-end Java SDK for scripting mode
– Improved the scripting call interface for uploading/downloading files in cross-application scenarios
– Provided an interface to support anonymous script requests on front-end Java SDK
– Solved anonymous script requests on Hive Node
– Optimized the interface of the front-end Hive Java SDK, solved unreasonable interface design problems, and carried out internal optimization and bug fixes
– Provided the first version of the Payment module implementation on back-end Hive node implementation and the corresponding RPC interface
– Based on the payment interface of the back-end Hive Node (under development) to implement the payment interface corresponding to the Hive Java SDK
