2.x Roadmap

Release overview

2.0.0 supports the long-awaited Raft cluster mode. Raft cluster mode eliminates dependence on third-party registration centers and Seata-Server back-end storage, making operation and maintenance simpler and more reliable. . In addition, AT mode supports SQLServer, Dameng and PolarDB-X 2.0 databases; it has unified the API of transaction mode; it supports two-stage transaction parallelism to greatly improve transaction performance; and it supports IPV6. It has passed more than 110 sets of cross-compatibility tests for jdk (8, 11, 17, 21) + Spring versions + OS (x86, arm64) + druid major versions, so you can upgrade smoothly with confidence.

The total number of files modified in this release is: 930, the cumulative code submitted is +56171 −6549, 182 PRs were merged, and a total of 47 people participated in code commit.
