| # [v2.5.0](https://github.com/FISCO-BCOS/FISCO-BCOS/releases/tag/v2.5.0) | ||
|
|
||
| ```eval_rst | ||
| .. admonition:: v2.4.x upgraded to v2.5.0 | ||
| - **Compatible upgrade** ：Directly replace the binary of the v2.4.x node with the `v2.5.0 binary <https://github.com/FISCO-BCOS/FISCO-BCOS/releases/download/v2.5.0/fisco-bcos.tar.gz>`_ , the upgraded version fixes bugs in v2.4.x. | ||
| - **Full upgrade** ：Refer to `Installation <../ installation.html>`_ to build a new chain and resubmit all historical transactions to the new node. The upgraded node includes new features in v2.5.0 | ||
| - `v2.4.0 Release Note <https://github.com/FISCO-BCOS/FISCO-BCOS/releases/tag/v2.5.0>`_ | ||
| ``` | ||
|
|
||
| ## Change description | ||
|
|
||
| **Added** | ||
|
|
||
| - Add precompiled contract, address 0x5, implement modular exponential calculation. | ||
| - Add precompiled contract, address 0x6, implement point addition (ADD) of elliptic curve alt_bn128. | ||
| - Add precompiled contract, address 0x7, implement the scalar multiplication (MUL) of elliptic curve alt_bn128. | ||
| - Add precompiled contract, address 0x8, implement a pairing function on a specific pairing-friendly elliptic curve for zkSNARK verification. | ||
| - Add precompiled contract, address 0x9, implement blake2 hash function. | ||
| - [Add flow control to achieve configurable node output bandwidth and maximum QPS](../design/flow_control.md) | ||
| - [Add ChainGovernance precompiled contract, address 0x1008, to implement role-based authority management](../design/security_control/ChainGovernance.md) | ||
| - [Add SDK connection node supports OSCCA-approved SSL, can be configured whether to enable](../manual/configuration.html#id10) | ||
| - [Add account management to freeze and unfreeze accounts](../design/features/account_management.md) | ||
|
|
||
| **Changed** | ||
|
|
||
| - In MySQL storage mode, the field type of the contract table is changed to mediumblob. | ||
| - [The OSCCA-approved cryptography is modified from the compile option to the configuration item.](../manual/configuration.html#id10) | ||
| - [Change the node to only accept the SDK connection of the same institution, can be configured whether to enable](../manual/configuration.html#p2p) | ||
| - Paillier homomorphic encryption and group signature are enabled by default. | ||
| - The build_chain script uses the private key as the root certificate and institution certificate of secp256k1. | ||
| - The storage of PBFTBackup was changed from LevelDB to RocksDB. | ||
| - Refactor the libdevcrypto module, optimize the code structure, and use TASSL to implement OSCCA-approved SSL and non-national TLS connections. | ||
| - Optimize lock implementation of storage module openTable. | ||
| - Optimize block data encoding to parallel. | ||
| - Optimize the large object destructor to asynchronous. | ||
| - Optimize log output mechanism to reduce the impact of log output on performance. | ||
| - Optimize the number of threads of MHD and transaction pool modules to reduce memory usage. | ||
| - Optimize MySQL storage adapter implementation, optimized ZdbStorage code implementation. | ||
|
|
||
| **Fixed** | ||
|
|
||
| - Fix an issue where the Entry was modified in the same block, and subsequent transactions query the Entry result error. | ||
| - Fix the issue that transactions in non-leader node transaction pool cannot be packaged under Raft consensus. | ||
| - Fix a deadlock issue with CachedStorage. | ||
| - Fix the problem of recovering from Binlog when Binlog is turned on in some extreme cases. | ||
| - Fix an issue that Viewchange was rejected after a node restart under certain circumstances the view could not be restored quickly. | ||
|
|
||
| **Compatibility** | ||
|
|
||
| The old version can directly replace the program upgrade | ||
|
|
||
|
|
||
| | | Recommended version | Minimum version | Description | | ||
| | ------------------ | ------------------- | --------------- | ------------------------------------------------------------ | | ||
| | console | 1.0.10 | 1.0.4 | | | ||
| | SDK | 2.5.0 | 2.0.4 | | | ||
| | generator | 1.5.0 | 1.2.0 | To use latest generator, please clone from master branch of generator repo. | | ||
| | FISCO BCOS browser | 2.0.2 | 2.0.0-rc2 | | | ||
| | Solidity | up to 0.5.2 | 0.4.11 | | | ||
| | amdb-proxy | 2.3.0 | 2.0.2 | | | ||
|
|
||
| **Compatibility mode rollback to v2.4.x method** | ||
|
|
||
| After a node is upgraded from v2.4.x to v2.5.0 in compatibility mode, the rollback can be completed directly by replacing the node binary back to v2.4.x. | ||
