+# Prompt Optimizer v2.9.3
+
+## Summary
+- Established an English-first runtime and documentation baseline while keeping `zh-CN` and `zh-TW` fully localized through the updated locale packs.
+- Fixed localization regressions that surfaced English-only toasts in context editing, favorites, Prompt Garden imports, template loading, history saves, and model-management error paths.
+- Hardened repository guardrails, MCP packaging/startup behavior, and cross-platform script checks so the rollout is safer on both developer machines and CI.
+- Extracted evaluation prompt template assets into dedicated content/runtime modules to make template maintenance easier and keep guardrail coverage explicit.
+
+## Highlights
+- The app now uses a more structured locale system: English is the baseline for shared runtime copy and docs, while Chinese users keep localized UI feedback instead of falling back to hardcoded English strings.
+
+## Product Updates
+### UI / Localization
+- Split the UI locale packs into modular `en-US`, `zh-CN`, and `zh-TW` sections so runtime copy, template labels, favorites messaging, testing strings, and image workflow text can stay aligned across languages.
+- Restored localized feedback for context import/export, Prompt Garden partial-success warnings, template loading failures, history record errors, favorite save flows, tag/category management, and text model manager failure toasts.
+- Added bootstrap and runtime guard tests to catch hardcoded runtime strings and locale drift before merge.
+
+### Core / Templates
+- Moved evaluation, rewrite, and structured-compare prompt assets into dedicated content/runtime modules instead of keeping large inline blobs in the service layer.
+- Added template guardrail tests so extracted prompt assets stay wired correctly as the evaluation stack evolves.
+
+### MCP / Repo Tooling
+- Hardened MCP packaging and startup integration, including the installable CLI entrypoint and language/config validation used by the English-first rollout.
+- Added repo-level locale parity and “no hardcoded Chinese runtime string” checks, then fixed the direct-execution path normalization so those checks behave correctly across Windows and Linux CI.
+
+## Fixes
+- Fixed mixed-language error messages where `zh-CN` / `zh-TW` users could still see English fallback text such as `Unknown error` or raw English toast copy.
+- Fixed MCP startup/default-language integration gaps so locale bootstrap behavior and tests stay consistent.
+- Fixed cross-platform script execution detection for repo guardrails when CI compares Linux `import.meta.url` values against Windows-style script paths.
+
+## Breaking Changes / Upgrade Notes
+- No breaking API or data-format changes.
+- This release does tighten locale and runtime-copy guardrails. If you maintain downstream customizations, expect stricter checks against untranslated runtime strings.
+
+## Developer Notes
+- The locale rollout is intentionally test-heavy: UI runtime guards, locale parity checks, no-hardcoded-runtime scans, MCP environment coverage, and package script validation all landed together so the baseline is enforceable instead of convention-only.
+- The evaluation template refactor is primarily internal, but it substantially reduces the maintenance cost of large prompt assets and makes content reviews more targeted.

+# Prompt Optimizer v2.9.3
+
+## 概括
+- 建立了 English-first 的运行时与文档基线，同时继续通过新的 locale 模块保证 `zh-CN` 和 `zh-TW` 界面反馈完整本地化。
+- 修复了一批本地化回归，避免上下文编辑、收藏、Prompt Garden 导入、模板加载、历史保存和模型管理错误路径再次冒出英文 toast。
+- 加固了仓库级校验、MCP 打包与启动行为，以及跨平台脚本判断逻辑，让这轮国际化改造在开发机和 CI 上都更稳。
+- 将评估提示词模板资产拆分为独立内容/运行时模块，后续维护和守护测试都更清晰。
+
+## 亮点
+- 应用现在采用更清晰的 locale 结构：英文作为共享运行时文案和文档基线，中文用户仍然会在失败路径和提示反馈里看到本地化内容，而不是硬编码英文。
+
+## 产品更新
+### UI / 国际化
+- 将 UI locale 拆分为模块化的 `en-US`、`zh-CN`、`zh-TW`，让运行时文案、模板标签、收藏提示、测试字符串和图像工作流提示在三种语言中保持结构一致。
+- 恢复了上下文导入导出、Prompt Garden 部分成功 warning、模板加载失败、历史记录保存失败、收藏保存、标签/分类管理，以及文本模型管理错误提示的本地化反馈。
+- 新增启动与运行时守卫测试，在合并前就拦住硬编码运行时字符串和 locale 结构漂移。
+
+### Core / 模板
+- 将评估、重写、结构化对比相关的提示词资产从服务层内联大段文本中抽离到独立 content/runtime 模块。
+- 为抽离后的模板补上守护测试，确保评估链路继续演进时不会把模板装配关系弄坏。
+
+### MCP / 仓库工具链
+- 加固了 MCP 的打包与启动集成，包括可安装 CLI 入口，以及这轮 English-first 改造依赖的语言/配置校验。
+- 增加了仓库级 locale parity 与“禁止硬编码中文运行时字符串”检查，并修复了这些脚本在 Windows 路径与 Linux CI 混用场景下的直接执行判断问题。
+
+## 修复
+- 修复了 `zh-CN` / `zh-TW` 用户在异常路径上仍可能看到 `Unknown error` 或原始英文 toast 的混合语言提示问题。
+- 修复了 MCP 启动默认语言与测试预期不一致的集成缺口，保证 locale bootstrap 行为和测试保持同步。
+- 修复了仓库守护脚本在 CI 中将 Windows 风格路径与 Linux `import.meta.url` 比较时失配的问题。
+
+## 破坏性变更 / 升级说明
+- 没有 API 或数据格式层面的破坏性变更。
+- 这次发布会更严格地检查 locale 与运行时文案。如果你有下游自定义运行时字符串，需要注意新的校验门槛。
+
+## 开发者说明
+- 这轮 locale 改造不是只改文案，还同时补上了 UI runtime guard、locale parity、禁止硬编码运行时字符串、MCP 环境覆盖和 package script 校验，尽量把约束固化成可执行检查。
+- 评估模板资产抽离主要是内部重构，但它显著降低了大块提示词内容的维护成本，也让后续 code review 更聚焦。
