为了提供更好的社区支持，我们在发布最新更新的同时，还对先前的版本进行修补，我们不断修正错误、提供稳定性升级。
本文概括了EOSIO和元素战争（Elemental Battles）最近的一些更新情况。
EOSIO
EOSIO-explorer v1.2.0
2020年5月5日，我们发布了eosio-explorer v1.2.0，版本升级到EOSIO v2.0.5
EOSIO v2.0.5
2020年4月21日，我们发布了EOSIO v2.0.5。这次更新包括安全性、稳定性和其它变化。
安全性
- 升级EOS-VM，增加了安全修复
稳定性
- 解决了trace_api_plugi的超时问题，因为http-max-response-time-ms的默认值很可能因为大区块增大
- 修复了OC的wrapped_fd move assignment operator函数可能的泄露问题
其他变化:
- 对trace_api_plug增加文件支持，以减少数据流冗余
- 改变了远程过程调用v1/trace_api/get_block，支持异步HTTP和get_block命令在可配置的http线程池使用，这和主应用线程不同
- 把develop branch上的变化融合到2.0.x
- 修改abi_serializer，利用yield 函数而不是死线和递归深度检查
- 修复了在途字节数过多的错误信息
- 引入异步HTTP API注册
- 解决了虚假HTTP相关的测试错误
- 去掉了需要用python2搭建EOSIO的要求
- 解决了带属性的域名导致Buildkite中某一步失败的问题
- 把获取信息的优先级上调到中高级
- 修复了第二个节点从节点同步的快照开始的问题
- 去掉错误代码400的断言检查
- 解决了macos-10.14构建图像的问题
- 用std::bind代替boost::bind，修复了boost 1.73 beta builds
- 增加对EOS VM的LLVM 10.0支持，保证简单的开箱即用构建
- 用shell 运算取代bc，防止标度值超过0时的用户配置失败
- 发现核心符号不是4.sys时，导致plugin_tests失败的问题
- 解决了$BLOCKSIZE值造成数学表达问题的问题
- 修复了State History Plugin发送区块时出现一区块延时的问题
- 实现不同环境下对run cicd脚本的支持
- 用户可以选择在所有测试可能都在CICD管道上运行的点改开始搭建
- 在README.md中，从shell codeblocks移除主要的$属性
- 重新编排内容、提高Trace API视图
- 修复了插件双标题的情况
- 改进了API参考介绍
- Updated manual build instructions
- 更新了手动搭建指导
EOSIO-swift v0.4.0
2020年4月14日，我们发布了eosio-swift v0.4.0.。
元素战争
2020年4月27日，我们发布了元素战争v1.1.12，更新到EOSIO v 2.0.5

In the interest of community support we continue to patch earlier builds with various bug fixes and stability updates in parallel with the releases of our latest builds.
This article contains a summary of the most recent updates for EOSIO and Elemental Battles.
EOSIO
EOSIO-explorer v1.2.0
On May 5, 2020 we released eosio-explorer v1.2.0, updating it to EOSIO v 2.0.5.
EOSIO v2.0.5
On April 21, 2020 we released EOSIO v2.0.5. Updates in this release include security, stability, and other changes.
Security
- Updated EOS-VM with security fixes
Stability
- Addressed a time-out issue with trace_api_plugin as it is very likely that the default value of http-max-response-time-ms must be increased for large blocks
- Fixed potential leak in OC’s wrapped_fd move assignment operator
Other Changes:
- Added compressed file support for trace_api_plugin to reduce redundancy in the data stream
- Changed the RPC call v1/trace_api/get_block to allow for asynchronous HTTP support and the get_block command to run on the configurable http-threads pool as opposed to the main application thread
- Merged changes on the develop branch to 2.0.x
- Modified abi_serializer to utilize a yield function rather than a deadline and recursion depth check
- Fixed too many bytes in flight error info
- Introduced asynchronous HTTP API registration
- Resolved spurious HTTP related test failure
- Removed requirement to have python2 to build EOSIO
- Resolved issue where names with characters caused a step in Buildkite to fail
- Increased get info priority to medium high
- Fixed issue where a second node is started from the same snapshot as the node being synced from
- Removed assert check for error code 400
- Addressed issue with macos-10.14 build image
- Fixed boost 1.73 beta builds by replacing boost::bind with std::bind
- Added support for LLVM 10.0 for EOS VM to ensure easy out-of-the-box building
- Replaced bc with shell arithmetic to prevent user configuration failures when scale values are set to greater than 0
- Identified issue causing plugin_tests failures where the core symbol is other than 4.sys
- Resolved an issue where $BLOCKSIZE values created issues for arithmetic expressions
- Fixed issue with the State History Plugin sending out blocks on a one block delay
- Implemented support to run cicd scripts from different environments
- Introduced option to start build where all tests may be run in the CICD pipeline
- Removed leading $ chars from shell codeblocks in README.md
- Reorganized content and improved Trace API overview
- Fixed double titles in plugins
- Improved API reference introduction
- Updated manual build instructions
