この記事は、2015年「MySQLマニュアルを読む」アドベントカレンダーの22日目です.
昨日の日記では、MySQLマニュアルのもくじより、レベル１（章レベル）の相違点について紹介しました。
今日は、その続きで、レベル２（節レベル）の相違を見ていきます。
なお、ここで章番号は、MySQL 5.7 マニュアルの章番号で書きます（MySQL 5.6 のマニュアルではなく）。
まず第１章General Information より、 1.5 に新たな節が追加されています。
1.5 Server and Status Variables and Options Added, Deprecated, or Removed in MySQL 5.7
MySQL 5.7 では多くの変数類（サーバ変数、ステータス変数、オプション）が変更になっています。過去の悪しきしがらみとの決別をようやくこのバージョンで決断したな、と評価できるところもあり、そんな情報がここにまとめられています。
続いて、11章と12章。MySQL 5.7 でJSON対応したのを受けて、各章に JSON型についての説明および、JSON関係の関数についての説明の節が追加されました。
11.6 The JSON Data Type
12.16 JSON Functions
14章。細かいことですが、14.6節が、従来の「InnoDB Table Compression」から「InnoDB Table and Page Compression」へと変更されています。圧縮が、テーブルだけでなくページも対象に加わったということでしょうか（中身はまだ読んでない）。
14.6 InnoDB Table and Page Compression
17.1は、表現上の変更なので、良いでしょう。
（Replication Configuration から Configuring Replication へ）
18章の前にあった MySQL Cluster(NDB)の章が除外されたので、18章から21章まで、MySQL 5.6マニュアルの章とひとつずつずれます。（MySQL 5.6 マニュアルでは 19章から22章)
21章 INFORMATION_SCHEMA の章では、1節が追加され、2節が除去されています。
追加：20.8 The INFORMATION_SCHEMA FILES Table
除外：旧21.30 INFORMATION_SCHEMA Tables for MySQL Cluster
除外：旧21.31 Thread Pool INFORMATION_SCHEMA Tables
22章が新たに追加されたのは機能の日記のとおり。sysスキーマについての章です。
（つまりMySQL 5.6 と比べて、章は、１増１減なので、トータルで26個の章から構成されているところは、結果として変わりません）
こんな感じ。
sysスキーマとJSONの、章または節レベルでの情報追加が、やはり MySQL 5.7 の「ウリ」として、マニュアルでも目立っていますね。
