Direct answer: On August 27 two core self-hosted projects shipped on the same day — Hermes Agent v0.20.6 rolls up ~525 PRs since v0.20.5 into a stable tag (headline: consent-gated real-browser profiles, a 50+ vendor-verified remote MCP catalog and new models), while DeepSeek Harness v0.1.2-alpha.1 (alpha channel) delivers a broad pass on session UX and multimodal, per-subagent model config, and bumps the pi-ai kernel to 0.84.2.
Hermes Agent v0.20.6: one big rollup
Officially a patch tag, but the volume is ~525 merged PRs / ~1,313 commits / 1,557 files changed (+177K/−21K), targeted at Docker images, hosted deployments and fresh installs. Highlights:
- Consent-gated real-browser profiles: use your default Chromium profile for local browsing (Windows close-with-approval flow) — no more login-state islands;
- Desktop browser gets its own OS window, plus a managed SSH remote-update engine and a fleet profile rail;
- Big remote MCP catalog expansion: 50+ live-verified vendor-hosted servers (Cloudflare, Grafana Cloud, Better Stack, Railway, etc.);
- TTL result caching for web_search/web_extract; lean-tail compression is now the default;
- OS-keychain encryption for stored secrets (no more per-launch macOS Keychain prompts);
- Updaters pause gateways over the control socket instead of tree-killing; image/package-managed installs refuse unsafe in-place updates;
- New models in the pickers: GLM-5.3-Flash, MiniMax M3 (free), MiniMax H3 Max (video).

DeepSeek Harness v0.1.2-alpha.1: a big UX pass
A new version line after 0.1.1-rc (alpha channel, early-adopter caveat). Highlights from the official bilingual notes:
- Performance & footprint: initial page load, session-loading transfer size and persistence storage all improved;
- Session UX: auto-collapsing process traces, resizable width, per-turn fine-grained usage, turn navigation, code highlighting kept during streaming;
- Multimodal: instant image echo, context compression counts image tokens, trace view shows image attachments, models can locate uploaded images;
- Per-subagent model config: tasks can pin provider/model/reasoning effort (Claude Code and Codex providers supported);
- Persistent-terminal fixes: macOS/Linux PowerShell startup misdetection, host stalls when Bash spawns many children, and more;
- Kernel bump: pi-ai upgraded to 0.84.2 (the Pi 0.84.x line we covered last week) — more evidence of the harness ecosystem riding the Pi kernel;
- Legacy APIProxy transport removed (use the Remote gateway with one-time token auth); Python Windows x64 artifacts added.
How to read it
Hermes packed half a quarter's work into a "patch" tag, focused on real-browser capability and MCP supply; DSH pours effort into session experience and subagent scheduling. Both point the same way: self-hosted agents are competing on "pleasant and controllable", not just "runs". For selection, cross-check the comparison hub and the Agent Harness entry in our glossary.

Direct answer: 8 月 27 日，两个 core 自托管项目同日发版——Hermes Agent v0.20.6 把 v0.20.5 以来的约 525 个 PR 汇总为稳定标签（最亮眼的是经用户同意的真实浏览器 profile、50+ 厂商验证的远程 MCP 目录与新模型接入）；DeepSeek Harness v0.1.2-alpha.1（alpha 渠道）带来会话交互与多模态的成批优化、子代理级模型配置，并把 pi-ai 内核升级到 0.84.2。
Hermes Agent v0.20.6：一次大汇总
官方口径：这是 patch 标签，但容量是 ~525 个合并 PR / 约 1,313 commits / 1,557 个文件变更（+177K/−21K），面向 Docker 镜像、托管部署与全新安装的稳定标签。要点：
- 经同意的真实浏览器 profile：用默认 Chromium profile 做本地浏览（Windows 关闭前需确认）——告别”登录态孤岛”；
- 桌面浏览器独立 OS 窗口 + 托管式 SSH 远程更新引擎 + 机队 profile 侧栏；
- 远程 MCP 目录大扩容：50+ 经实测验证的厂商托管服务器（Cloudflare、Grafana Cloud、Better Stack、Railway 等）；
- web_search/web_extract 的 TTL 结果缓存；lean-tail 压缩成为默认；
- OS 钥匙串加密存储密钥（macOS 不再每次启动弹钥匙串）；
- 更新器通过控制 socket 暂停网关（不再杀进程树）；镜像/包管理安装拒绝不安全的原地更新；
- 新模型进选择器：GLM-5.3-Flash、MiniMax M3（免费）、MiniMax H3 Max（视频）。
DeepSeek Harness v0.1.2-alpha.1：体验大修
0.1.1-rc 线之后的新版本线（alpha 渠道，尝鲜口径），官方中文 release notes 要点：
- 性能与体积：页面初始化、会话加载传输量、持久化存储体积全面改善；
- 会话交互：自动折叠会话过程、宽度可调、每轮精细用量展示、轮次导航、流式输出保持代码高亮；
- 多模态：图片发送即回显、上下文压缩计入图像 Token、轨迹视图展示图片附件、模型可定位已上传图片；
- 子代理可配置模型：任务可按提供方/模型/推理力度指定（Claude Code 与 Codex 提供方支持）；
- 持久终端系列修复：macOS/Linux PowerShell 启动误判、Bash 派生大量子进程的宿主卡顿等；
- 内核升级：pi-ai 升至 0.84.2（即上周我们报道的 Pi 0.84.x 线）——harness 生态与 Pi 内核的联动再添实证；
- 移除旧版 APIProxy 传输层（改用 Remote 网关+一次性 Token 鉴权）；新增 Python Windows x64 产物。
怎么看
Hermes 用一个”patch 标签”装下了半个季度的工作量，重心在浏览器真实化与 MCP 供给；DSH 则把火力放在会话体验与子代理调度。两者都指向同一趋势：自托管 Agent 的竞争已从”能跑”转向”好用+可控”。选型仍可对照对比总览与术语表里的 Agent Harness 词条。
