v3.3.0

What's New

• Snappier menu bar and popover. Aggregation work moved off the
  main thread — Stats / All Time / Usage tabs no longer hitch on
  first open.
• Faster startup. Only the selected provider (plus Codex when
  notch is enabled) does the full session scan at boot. Other
  providers stay cold until you open their tab.
• Smoother search. Session list FTS search runs in the
  background with stale-result discarding; transcript search reads
  precomputed indexes instead of rebuilding the matched fields per
  keystroke.
• Lower memory peak for large transcripts. Parsers iterate file
  bytes directly; the whole-file String allocation is gone.
• Faster cache rebuild. Per-batch SQLite transactions with
  reused prepared statements replace the per-session BEGIN/COMMIT
  cycle.

Under the Hood

• Seven-PR performance pass with OSSignposter instrumentation
  throughout; baseline measurement scripts at scripts/perf-*.
• Combined Claude parse + FTS extract path saves one file IO per
  dirty session.
• Status bar and notch behavior unchanged — every PR enforced this
  as a hard constraint.

更新内容

• 菜单栏和 popover 更跟手。 聚合计算移到后台线程,
  Stats / All Time / Usage 标签首次打开不再卡顿。
• 启动更快。 只有当前选中的 provider（以及灵动岛启用时的
  Codex）会在启动时做完整扫描; 其他 provider 保持冷启动,
  切过去时再加载。
• 搜索更顺滑。 会话列表的 FTS 搜索改异步并丢弃过期结果;
  转录页内搜索改读预计算索引, 不再每次按键重建字符串。
• 大转录峰值内存降低。 parser 直接按字节遍历文件,
  整文件 String 分配被消除。
• 缓存重建更快。 批量 SQLite 事务 + 复用 prepared statement
  替代每会话一个 BEGIN/COMMIT。

内部细节

• 7 个 PR 的性能优化, 全程 OSSignposter 埋点;
  scripts/perf-* 提供 baseline 测量脚本。
• 合并 Claude parse + FTS 提取路径, 每个脏会话省一次文件 IO。
• 状态栏 / 灵动岛行为完全不变 —— 每个 PR 都把这点作为硬约束验证。
