v0.3.0

Added

• Per-model pricing: session rows and daily/monthly stats bill each session at the price table of the model it actually used (v4-flash / v4-pro), so sessions that switched models stay accurate
• auto price mode: flat legacy rates until 2026-08-17 00:00 Beijing time, then automatically switches to DeepSeek's official peak/off-peak schedule; the footer badge shows flat / peak / off-peak rate accordingly — no config change needed

Changed

• Footer redesigned into three columns: status + price mode | current cost | date + time
• Stats view simplified: dropped "Summary"/"Trend" headings, cumulative total label enlarged into one line
• Curve Y axis reworked: unit label always visible, compact ticks (1B/500M), floating value pill at the latest point
• Stats and live views aligned to identical heights; footer cost unified with stats figures

Fixed

• Invisible budget bar (0.2.2 regression): replaced nonexistent theme tokens with the real suffixed variables
• Stats view crash (0.2.2 regression): React Hooks order violation
• Overestimated session cost: sessions mixing models were billed entirely at the current model's rate
• Double-container whitespace and grey scrollbar strip in the stats view

---

新增

• 按模型分别计价：会话行、按日/按月统计按各会话实际使用的模型（v4-flash / v4-pro 等）套用对应价格表，切换过模型的会话不再整段按单一模型计价
• auto 价格模式：2026-08-17 零时（北京时间）前自动使用 flat 旧价，之后自动切换 DeepSeek 官方峰谷价（高峰 9-12 / 14-18），底部徽章同步显示「标准价 / 高峰价 / 空闲价」，无需手动改配置

变更

• 底部栏改为三列布局：状态 + 价格模式 ｜ 当前花费 ｜ 年月日 + 时间
• 统计视图排版精简：删除「汇总」「趋势」标题，累计消耗标签加大单行显示
• 曲线 Y 轴重排：单位标签常驻、紧凑刻度（1B/500M）、当前值胶囊浮动在最新点旁，大数值不再重叠
• 统计与实时视图高度精确对齐；底部当前花费与统计口径统一

修复

• 预算进度条不可见（0.2.2 引入的缺陷）：主题 token 名称错误，已替换为主题真实定义的带后缀变量
• 统计视图崩溃（0.2.2 引入的缺陷）：React Hooks 顺序违规导致切换统计视图时面板消失
• 会话成本高估：会话混用模型时整段按当前模型计价的问题
• 统计视图双层容器造成的多余空白与灰色滚动条条带

v0.2.2

Added

• Editable budget & balance: click values in the stats view to edit inline (Enter saves / Esc cancels); balance decreases locally with estimated token consumption, falls back to the API balance when unset
• Current cost in the footer: cumulative estimated cost shown bottom-right
• Peak rate readout: peak consumption rate (t/s) above the live curve

Changed

• UI layout rework: enlarged section captions (13px), big-number hierarchy + segmented controls, keeping the tech feel
• Session list shows only the current session by default
• Daily / monthly detail lists collapsed by default

Fixed

• Removed the stats view's old flat layout and border lines

---

新增

• 可编辑预算与余额：统计视图点击数值行内编辑（回车保存 / Esc 取消）；余额按 token 消耗本地估算递减，未设置时回退 API 余额
• 底部显示当前花费：面板底部右侧统一显示累计估算花费
• 峰值读数：实时趋势区显示窗口内峰值消耗速率（t/s）

变更

• UI 排版重构：分区小标题加大（13px）、大数字层级 + 分段控件，保留科技感
• 会话列表默认只显示当前会话，展开才显示全部
• 按日 / 按月明细默认收起（0 行），点击展开全部

修复

• 移除统计视图旧的平铺布局与边框线（改留白分区）

v0.2.1

Fixed

• Session-row and account-balance hover hints now auto-fade (fade in ~1.5s then fade out on their own, never lingering while hovered); native browser tooltips removed

---

修复

• 会话行、账户余额悬停气泡全部改为自动消失样式（淡入约 1.5 秒后自动淡出，指针停留也不会一直显示），并移除浏览器原生 tooltip

v0.2.0

Added

• Per-session cost (¥): every live row shows a green estimated cost
• Panel drag system: drag the pill or header, position remembered across reloads; may drag past screen edges with a grabbable header strip; pointer capture + 4px threshold
• Long-press position menu (hold 0.6s): back to default, corner presets, custom position, SVG stroke icons
• Y-axis ticks & auto-scaling: value labels + gridlines, 1/2/2.5/5×10ⁿ rounding with hysteresis
• Current-value indicator: dashed leader with a live value pill
• Peak/off-peak pricing mode: priceMode: peak-offpeak switches prices by Beijing time
• TPS readout, account balance (5-min cache), monthly budget bar, historic-session persistence

Changed

• Closing with ✕ no longer resets the position
• Stats view lists every date and month

Fixed

• Idle curves drop to zero; time ticks no longer clipped; fractional ticks keep one decimal; stats refresh immediately; gesture conflicts; preset corner offset; drag-back handle; single-click open

---

新增

• 会话花费显示：实时视图每个会话行显示绿色 ¥ 估算花费
• 面板拖拽系统：位置跨刷新记忆、可拖出屏幕边缘但保留可抓取的头部栏、指针捕获 + 4px 阈值
• 长按位置菜单（按住 0.6 秒）：回到默认位置、四角预设、自定义位置、SVG 描边图标
• Y 轴坐标与自动缩放：刻度 + 网格线，1/2/2.5/5×10ⁿ 取整 + 滞回
• 当前值指示线：虚线引导线与实时数值胶囊
• 峰谷计价模式、TPS 显示、账户余额（5 分钟缓存）、月预算进度条、历史会话持久化

变更

• 点「✕」收起面板不再重置位置
• 统计视图「按日/按月」显示全部日期与月份

修复

• 曲线空闲归零、时间刻度不再裁切、小数刻度保留一位、统计切换即时刷新、手势冲突、预设角落偏上、拖出屏幕后可抓回、单点打开面板

v0.1.0

Added

• First release: live view (session pressure / cumulative / details / curves), stats view (daily / monthly / durable logs), DeepSeek official-rate cost estimates, bilingual zh/en UI

---

新增

• 初版发布：实时视图（会话压力/累计/详情/曲线）、统计视图（按日/按月/持久化日志）、DeepSeek 官方价成本估算、中英双语界面
