Release notes:

0.22.5 -> 0.22.6 对照

0.22.6 是 P/D 分离的第一个 stable 版本：这版把 P/D RDMA push 路径的性能稳定性、正确性保护、布局兼容和发布包完整性一起补齐。0.22.5 是上一版 release baseline；0.22.6 是推荐用于 P/D 分离的正式版本。

| 维度 | 0.22.5 | 0.22.6 | | --- | --- | --- | | P/D 分离 | 基础发布状态，P/D 路径仍在收敛 | 第一版 stable：P/D RDMA push、scheduler/worker 协议、prefill/decode 流程、proxy 和 native RDMA binding 都经过稳定化 | | 性能 | RDMA push 和布局映射还缺少本轮优化 | 支持 MLA cache layout；优化 layout mapping；补齐 connector metrics；提升 RDMA push 发送、完成通知、等待路径和链路利用率观测 | | 正确性 | 对版本不匹配、零命中 query probe、RDMA-only query path 等边界保护不足 | vLLM/server 版本不匹配 fail early；零命中 query probe 不再错误释放 lease；RDMA-only query path 加 cfg-gate；vLLM 启动失败更早暴露 | | 发包 | CUDA 13 wheel 使用 --no-default-features --features cuda-13，会关掉默认 rdma | CUDA 13 CI/release wheel 显式使用 --features cuda-13,rdma；cu12 和 cu13 包都带 RDMA | | 其他修复 | SSD cache 单路径 | SSD cache 支持多路径；清理未使用 Rust 依赖；测试门禁和 e2e cargo feature 对齐 |

0.22.5 -> 0.22.6 Comparison

0.22.6 is the first stable P/D disaggregation release. It closes the loop on P/D RDMA push performance, correctness guards, cache-layout compatibility, and package completeness. 0.22.5 is the previous release baseline; 0.22.6 is the recommended release for stable P/D disaggregation.

| Area | 0.22.5 | 0.22.6 | | --- | --- | --- | | P/D disaggregation | Baseline release state, with the P/D path still converging | First stable release: P/D RDMA push, scheduler/worker protocol, prefill/decode flow, proxy, and native RDMA binding have been stabilized | | Performance | RDMA push and layout mapping had not received this round of optimization | Adds MLA cache layout support; optimizes layout mapping; adds connector metrics; improves RDMA push sending, completion signaling, wait behavior, and link-utilization visibility | | Correctness | Edge cases such as version mismatch, zero-hit query probes, and RDMA-only query paths were under-protected | Fails early on vLLM/server version mismatch; avoids incorrect lease release for zero-hit query probes; cfg-gates RDMA-only query behavior; fails faster when vLLM startup dies | | Packaging | CUDA 13 wheels used --no-default-features --features cuda-13, which disabled default rdma | CUDA 13 CI/release wheels now explicitly use --features cuda-13,rdma; both cu12 and cu13 packages include RDMA | | Other fixes | Single SSD cache path | Multiple SSD cache paths; unused Rust dependencies removed; test gates and e2e cargo features aligned |
