v1.0.0 — 首个完整版本：会话内用量解释器

三视角轮次图（全部历史横向滚动）+ 每轮成本/耗时/异常解释卡 + 多币种成本与实时汇率 + 账户余额。
本次收官：轮次图从「最近 12 轮」升级为「全部轮次横向滚动」（固定细柱宽、自动滚到最新、箭头/渐隐提示）。

v0.3.0

v0.3.0

感谢 myp-super 的 PR #5：成本显示币种（USD/CNY 切换 + 实时汇率刷新）。

新增

• 成本显示币种：config.currency（'usd' | 'cny'）与 config.cnyPerUsd（默认 6.76）
• 成本区 USD/CNY 切换按钮，选择在浏览器中记住（localStorage）
• 「刷新汇率」按钮：经 /dsh-usage-chart/rate 代理拉取最新 USD→CNY 汇率并立即重估
• /dsh-usage-chart/meta 路由下发显示币种配置

修复

• 汇率刷新健壮性：默认源（open.er-api.com）不可达时自动回退内置备用源（frankfurter.dev）；上次成功汇率持久化，断网刷新沿用真实汇率
• 槽位注册改为 ctx.slots.inject 等待声明，修复 slot "…" is not declared

升级：dsh plugin --profile web add dsh-usage-chart@0.3.0（未全局装 dsh 时前缀 npx --yes @deepseek-ai/dsh）

详见 CHANGELOG.md / CHANGELOG_ZH.md

v0.2.0: docs: v0.2 wrap-up — bilingual changelog, roadmap/architecture refresh

- New CHANGELOG_ZH.md (full zh changelog for 0.2.0/0.1.1/0.1.0); add to
  package files; cross-links from CHANGELOG.md and both READMEs.
- CHANGELOG.md: record the host-model-attribution fix and add an upgrade
  note (restart dsh web required — the Host caches plugin code in memory).
- README.md / README_EN.md: upgrade note for v0.2.0 + changelog links.
- docs/ROADMAP.md: mark v0.2.0 delivered with verification record; detail
  the v0.3.0 context-diagnosis plan (contextBreakdown/compaction/source
  attribution); add a prioritized backlog of v0.2-derived optimizations
  (pricing snapshot refresh, session-scope UX, indicator model attribution,
  large-session fold truncation, official price fetching).
- docs/ARCHITECTURE.md: map the current state to v0.2 (21 source files),
  resolve the four v0.1 friction points, note v0.2 observations, refresh
  the version matrix and test surface (28 tests + live E2E).

v0.1.1: fix: read balance key from DSH credentials; mark react peer optional

- Balance: resolve the DeepSeek API key via ctx.get('credentials') so a key
  set in the web UI (Settings -> Models) or .credentials.yaml works without
  an env var or plugin config (cordis requires ctx.get for services not
  declared in inject).
- peerDependencies: mark react optional (provided by the DSH web platform),
  removing the pnpm \"missing peer react\" warning on install.
- Docs: uninstall/cleanup steps and install FAQ; bump version to 0.1.1.

v0.1.0

[Unreleased]

[0.1.0] - 2026-08-14

Added

• Composer usage indicator and expandable SVG dashboard.
• Session token, cache, context-pressure, model, and estimated-cost views.
• Per-turn usage chart with total/mix views, hover and keyboard tooltips, and a
  highlighted current-round band; host-side per-turn aggregation from the session log.
• Host-side DeepSeek balance proxy.
• Full zh/en localization: the indicator, dashboard, charts, and balance views follow
  the DSH in-app Language setting through the locale service (dictionaries registered
  under the dsh-usage-chart namespace; browser language only seeds the initial value).
• Release metadata, bilingual documentation, CI, contribution/security policies, and
  portable visual probe scripts (scripts/*.mjs).
• Privacy-safe README demo screenshot with fictional usage values and no account data.

Fixed

• Light-mode readability: indicator, panel, and SVG charts now use DSH theme tokens
  (--dsw-alias-label-* / --dsw-alias-bg-*) and theme static palette colors, so text
  and chart segments stay legible in both light and dark appearances.

Security

• Restrict Host JSON routes to same-origin GET requests.
• Require HTTPS for custom API endpoints, except loopback HTTP proxies.
• Validate token-usage samples before aggregation.
