# v0.25.10 Release Notes

> v0.25.9 -> v0.25.10

## Summary

Introduces a three-tier conversation memory architecture — context window, ToriiDB vector search, and SQLite full-text archive — so that no message is ever lost regardless of history compaction or session resets. Trims rarely-used bundled API definitions to reduce tool-discovery noise.

引入三層對話記憶架構——上下文視窗、ToriiDB 向量搜尋、SQLite 全文歸檔——確保無論 history 裁剪或 session 重置，任何訊息都不會遺失。移除不常用的內建 API 定義以降低工具探索噪音。

## Changes

### ADD
- Add SQLite-backed history store with FTS5 full-text search, dual-write on every message append, auto-backfill for existing sessions, and compact-safe `session_meta.start_at` tracking (@pardnchiu) [0442dd9]
- Add `MaxHistoryBytes` runtime limit (default 5 MiB) with auto-compact to 80% on user+assistant pair boundary, including ToriiDB cleanup for entries before the cutoff (@pardnchiu) [0442dd9]
- Add `mode` parameter to `search_conversation_history` tool: `keyword` routes to SQLite FTS5 + ToriiDB substring, `semantic` routes to ToriiDB VSearch (@pardnchiu) [0442dd9]
- Add outstanding contributors section to bilingual READMEs (@pardnchiu) [e64098d]

<details>
<summary>翻譯</summary>

- 新增 SQLite 歷史儲存層，支援 FTS5 全文搜尋、每次 append 雙寫、既有 session 自動回填、compact-safe 的 `session_meta.start_at` 追蹤
- 新增 `MaxHistoryBytes` runtime limit（預設 5 MiB），超過時自動裁剪至 80%（user+assistant pair 邊界），同步清理 ToriiDB 早於裁剪點的 entries
- `search_conversation_history` 工具新增 `mode` 參數：`keyword` 走 SQLite FTS5 + ToriiDB 子字串、`semantic` 走 ToriiDB VSearch
- 雙語 README 新增傑出貢獻者區段
