+### Changed
+- **Report generation is much faster, especially on repeat clicks**: generating the "Today"/"Last 7 days" HTML report used to re-open and re-parse every Antigravity conversation database and re-scan Codex's OTel trace log from scratch every time, and recomputed the same entry's local date and working-directory-to-project-name mapping repeatedly within a single report build. All three now cache appropriately (file-level caching for the SQLite sources, in-memory caching scoped to each report build), so a repeat click of the same period is dramatically faster with no change in the numbers shown.

+## [0.27.3] - 2026-07-15
+
+### 變更
+- **產生使用報告快了不少，尤其是重複點擊時**：以前點「今天」「七日」的 HTML 報告，每次都會把所有 Antigravity 對話資料庫、Codex 追蹤紀錄從頭重新開啟解析一次，而且同一批資料在單次報告產生過程中，本地日期與工作目錄對應的專案名稱也會被重複計算好幾次。現在這三處都補上了對應的快取（SQLite 來源用檔案層級快取、單次報告內的重複運算用當次記憶體快取），同一個期間第二次點擊會快上許多，數字結果不受影響。
