Bump Desktop to 0.12.4 and the separately published GoodBuddy Agent to 0.11.18. Add the approved bilingual release notes for HTML previews, long-run and queue reliability, remote terminal-state convergence, and faster OpenCode follow-up on Linux ARM.
This candidate uses the standard six-platform x64/arm64 matrix and does not request a LoongArch experimental preview.
Agent replies that produced HTML could only be read as source, so users had
to copy the markup into an external file to see the result. Completed Agent
and Subagent output now renders complete HTML documents, single-root HTML
replies, and `html` / `htm` code blocks as an isolated static preview in
place. Each preview keeps a persistent notice that scripts and network are
disabled and offers the same icon actions as Mermaid diagrams: a source
toggle and a full-screen preview. The new "render HTML in conversations"
switch under Platform Features / General is on by default, applies to the
open conversation immediately, and falls back to HTML source when disabled.
Previews cannot run scripts, reach the network, submit forms, open windows,
or load remote media; author stylesheets and inline styles are preserved so
the intended layout survives, and remote resource loading is refused by the
preview CSP instead.
Direct-model replies no longer fail once they grow large. The byte caps on
streaming responses, single stream blocks, non-streaming replies, model tool
arguments, tool request context, aggregate tool results, and accumulated
answer text are removed, so users stop seeing "模型接口流式响应超过安全限制"
on long answers. Response length is now governed by the request timeout,
cancellation, and context compression. Image generation responses keep their
decodable-image validation.
A message sent after a failed or interrupted run stayed in the pending queue
instead of running. The conversation is now released whenever a run reaches
any terminal state, not only when the renderer reports readiness again, and a
dispatched queue item whose run never starts releases its reservation and
returns to pending. Later messages dispatch without extra user action.
Release note: Agent 回复中的 HTML 现在可直接在会话内预览，支持查看源码和全屏预览，默认开启并可在“平台功能 / 通用设置”关闭；直连模型的长回复不再因大小限制中断；上一次运行失败或被中断后，新发送的消息会立即执行而不再排队等待。
Long Runtime sessions could silently stop retaining tool and Subagent activity, truncate Run history details, and reject workspace previews over 256 KB. Run history now persists in Main SQLite without the former fixed record or detail caps, surfaces possible loss from legacy caches, and renders long histories in batches.
Local and remote workspace previews now load UTF-8-safe 256 KiB pages on demand instead of rejecting larger text files. The legacy migration, clear-data path, IPC contracts, tests, and feature documentation are updated with the resulting behavior.
Release note: 长时间 Runtime 运行现在会完整保留工具和 Subagent 活动；运行记录迁移到 SQLite，并提示旧版可能已丢失的内容。超过 256KB 的本地及远程文本文件可通过分页面预览继续加载。
OpenCode status checks could cold-start throwaway servers, unrelated
conversations could block each other, and model, Continue, or remote paths
could replay or duplicate work under failure and backlog conditions. Settings
could also lose edits or overwrite unrelated model fields.
This update makes status checks passive, keeps per-conversation ordering while
allowing concurrency, preserves native long-running work with bounded display
capture and backpressure, narrows retries to known pre-dispatch failures, and
aligns remote Ask permissions without reducing Execute. It also keeps
Embedding updates narrow, improves settings and browser guidance, removes the
unused legacy Main gateway state, and records the validated Desktop 0.12.3 and
Agent 0.11.17 release metadata.
Release note: 改善 OpenCode 切换、多会话长任务、模型重试、远程 Ask/Execute 与设置保存可靠性，并完成 Desktop 0.12.3 / Agent 0.11.17 发布准备。
Model connections can now save bounded JSON request headers and top-level body fields. Direct requests and Continue support both; local OpenCode and DeepSeek Harness use only native header support, while the managed remote OpenCode gateway applies both.
Runtime, protocol, and authentication fields keep precedence. Custom values are ordinary connection settings, not credential storage. This migrates Runtime settings from v20 to v21 and updates the DeepSeek control and managed Runtime ACP capabilities.
Release note: 模型连接详情新增自定义请求头和请求体；直连与 Continue 支持两者，本地 OpenCode 和 DeepSeek Harness 仅应用原生支持的请求头，受管远程 OpenCode 支持两者，界面会明确提示生效范围。
The built-in browser was limited to direct-model tools, and its Agent switch also blocked manual Browser workbar actions. It is now a request-scoped GoodBuddy capability assignable to direct models, managed OpenCode, and Continue, while manual browser controls remain available when Agent access is off.
Existing browser enablement migrates to capability settings version 6. DeepSeek Harness remains unsupported.
Release note: 内置浏览器现在可分配给直连模型、OpenCode 和 Continue；关闭 Agent 浏览器能力不会影响用户在浏览器工作栏中的手动操作。
Local embedded OpenCode serialized otherwise independent conversations, and GoodBuddy could stop long Runtime tasks after fixed tool, activity, model-call, or accumulated display-output limits.
Different conversations can now run concurrently while requests in the same conversation stay ordered. Dynamic MCP tools remain isolated to the current request. OpenCode, Continue, managed ACP, and the Agent model gateway no longer stop native execution at GoodBuddy-defined call counts or prompt-wide output totals; display copies truncate and transport queues apply backpressure instead. Prompt-wide quota fields are removed from the current contracts.
Per-call model settings, provider request timeouts, cancellation, and same-conversation ordering remain unchanged.
Release note: 修复本机 OpenCode 不同会话互相等待的问题，并移除 GoodBuddy 对单次 Runtime 工具、活动和模型调用次数的人为上限；长输出现在只截断展示或施加传输背压，不再取消原生任务。
The published Agent 0.11.14 predates the registered-Runtime activation change included in the Desktop candidate. Bump the Agent lock to 0.11.15 and the unpublished Desktop recovery to 0.12.2 so the compound package minimum Desktop version, bilingual notes, and feature documentation describe one coordinated release.
Keep v0.12.0 and v0.12.1 immutable and unpublished, and document that Agent tags also require the exact main candidate workflow to pass before tagging.
Release note: 托管 Linux Host 使用 Agent 0.11.15，已登记 Runtime 激活时不再重复检查完整 OpenCode 二进制。
Managed Python installation rejected valid case-distinct terminfo symlinks in the pinned Astral archives on Linux x64 and arm64. Archive uniqueness now follows the target filesystem: Linux preserves case-distinct paths, while every target still rejects exact duplicates and unsafe entries.
Move the unpublished 0.12.0 bilingual release notes to the immutable-tag recovery version 0.12.1 and record the failed tag evidence.
Release note: 修复 Linux x64/ARM64 上托管 Python 因官方归档包含大小写不同路径而无法安装的问题。
The Linux routing test still referenced the obsolete bin/opencode name. With intentional path-only Runtime selection, that stale fixture was no longer masked by automatic discovery; use the locked opencode-ai 1.18.9 bin/opencode.exe entrypoint on every platform.
Keep the approved 0.12.0 notes and bilingual feature matrices explicit that local OpenCode paths are not prevalidated and fail only at actual launch.
Full-suite resource contention could make asynchronous renderer assertions and short runtime timing tests fail even though focused runs passed. Limit Vitest to two workers and give the affected UI operations the existing three-second async window.
Also include the approved Linux ARM OpenCode startup note in both feature matrices and release-note languages, and record the successful isolated Linux x64 Host validation of the current-source Runtime activation path.
Update the desktop version, approved bilingual release notes, and synchronized English and Chinese feature matrices for the 0.12.0 candidate.
Release preparation now runs local tests, type checks, and lint without a local production build, then requires the main-branch CI build before tagging. The package matrix uses a native Windows arm64 runner and validates managed Python on every target without adding extra license files to the desktop package.
