MediaWiki 1.31 は、MediaWiki の最新リリースです. 変更点の完全な一覧は を参照してください. 2017年9月26日より、漸増する「wmf」ブランチを通して、ウィキメディア財団のウィキ群に展開されました. 1.31.0 安定版リリースは、2018年6月13日にリリースされました. をダウンロードするか、Git 内の  ブランチをチェックアウトしてこのリリースに追随してください.

より多く同梱された拡張機能
MediaWiki の tarball に同梱されている拡張機能集が増加しています. 新しく追加されたものは以下のとおりです：
 * はウィキ上で CSS および JavaScript を編集する際のより使いやすいエディタを提供します.
 * は画像およびギャラリーの lightbox ビューアを提供します.
 * はウィキアカウントの二要素認証を提供します.

手違いにより、Nuke 拡張機能は MediaWiki 1.31.0 の tarball には含まれていません. この拡張機能を使用したい場合は、個別にダウンロードしてください. これは次回の MediaWiki のリリースで修正される予定です.

Timeless スキン
Timeless は MediaWiki の新しいレスポンシブスキンで、バンドルされるようになりました.

CologneBlue および Modern
現在も MediaWiki に対応していますが、CologneBlue および Modern スキンは同梱されなくなりました. それらのスキンを更新またはインストールする場合は、個別にダウンロードしてください.

HTML 5 構文解析アルゴリズムに置換された Tidy

 * 詳細はを参照してください

正しくないウィキテキストを現代的で標準に準拠した方法で整形するため、HTML 4 ベースの Tidy ライブラリが PHP のみで書かれた HTML 5 構文解析器 RemexHtml に置き換えられています. 行われなくなる tidy の整形にコンテンツが依存している場合は、それらを修正する必要があります.

Parsoid とともに Linter 拡張機能 を使用することで、RemexHtml 構文解析器を利用したレンダリングの際に差異が生じる問題が発生するページを割り出すことができます. ParserMigration 拡張機能は、エディタに tidy および RemexHtml を利用したレンダリングの比較を横に並べて表示します.

ウィキ間利用者名
MediaWiki は、版やログエントリ等において " " のような形式の「ウィキ間」利用者名をサポートするようになりました. これにより、外部のウィキ（例えば Wikibase によって生成されたもの）からのページの取り込みやイベントの正確な記録が可能となり、 現在存在する、あるいは将来作成される可能性があるローカルアカウントによって混乱することがなくなります.


 * ページの取り込みは、不明な（オプションで既知のものも）利用者名を " " のような形式で記録するようになります.
 * （履歴ページ、ログページ等で使用されています）は、 というウィキテキストのように、" Example" という形で利用者名を表示します.

さらなる UI の標準化

 * MediaWiki プロジェクトを横断したダイアログボックスの標準化の最初のパスとして、Html クラスが messageBox、successBox、errorBox および warningBox を生成するためのヘルパーメソッドを提供するようになりました.

その他の機能の変更

 * すべての利用者に対して、90編集/分という既定の編集速度制限を追加します. これは の設定によって変更することができます.
 * は  アクションにのみ影響します.
 * 環境設定オプションを安全に配置できるようにするため、 と名付けられた利用者サブページは、  や   ページと同様の方法で保護されるようになりました.
 * ファイルページの情報ページは、基本情報表においてファイルの base-16 SHA1 ハッシュ値を表示するようになりました.
 * pingback 機能は、1月に1回、活動中のウィキを割り出すための heartbeat ping を送信します.
 * 存在しないページにリンクするタブ（未作成の議論ページへのタブ等）は、色だけでなく、状態を示すツールチップを持つようになります.

PHP7 または HHVM が必要になりました
MediaWiki 1.31 は PHP 7.0.0 以降を必要とします. HHVM 3.18.5 以降もサポートしますが、長期間のサポートのため、一般に PHP 7.0.0 以降の使用が推奨されます.

データベースの変更
1.31 には 1.30 からいくつかのデータベース変更があり、スキーマ更新をしなければ動作しません.

Revision テーブル
リビジョンテーブルのようないくつかのとても大きなテーブルへの変更のため、スキーマ更新には非常に長い時間（中規模サイトで数分、大規模サイトで数時間）がかかる可能性があることに注意してください. 更新前には常にデータベースをバックアップすることを忘れないでください！

Archive テーブル
If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply schema changes, and cannot have downtime to run  and apply   manually, you'll have to apply a default value to the   and   columns of the   table or make those columns nullable before upgrading to MediaWiki 1.31. shows how to do this for MySQL.

Actor table
The identity of the logged-in or IP "actor" for logged actions is being moved into a new  table, with the rows in tables such as revision and logging referring to the actor ID instead of storing the user ID and name/IP in every row.


 * This is currently gated by . Most wikis can set this to  and run   as soon as any necessary extensions are updated.
 * Most code accessing rows for logged actions from the database should use the relevant  methods to get the information needed to build the SQL query. The   class may also be used to get feature-flagged information needed to access actor-related fields during the migration period.

環境設定の変更

 * now defaults to  instead of.
 * was removed and will be ignored.
 * , deprecated and ignored since 1.25, was removed. See the 1.25 release notes for more information.
