+  ### New filtered stream operators: affiliate targeting and follower thresholds
+
+  Today, we added three new operators to the X API v2 [filtered stream](/x-api/posts/filtered-stream/integrate/operators) to help you build more precise rules:
+
+  - `from_affiliate_of:` — matches Posts from affiliates of a specific user (e.g. `from_affiliate_of:XDevelopers`).
+  - `to_affiliate_of:` — matches Posts in reply to affiliates of a specific user (e.g. `to_affiliate_of:XDevelopers`).
+  - `min_followers:` — matches Posts from users with at least the specified follower count (e.g. `min_followers:1000`).
+
+  Use the affiliate operators to track conversations across an organization's affiliated accounts, and `min_followers:` to filter out low-reach Posts at the rule level.

+  - `to_affiliate_of:` — coincide con Posts en respuesta a afiliados de un usuario específico (p. ej., `to_affiliate_of:XDevelopers`).
+  - `min_followers:` — coincide con Posts de usuarios con al menos el número de seguidores indicado (p. ej., `min_followers:1000`).
+
+  Usa los operadores de afiliados para seguir conversaciones entre las cuentas afiliadas de una organización, y `min_followers:` para filtrar Posts de bajo alcance a nivel de regla.

+  ### 新しい Filtered stream オペレーター: アフィリエイトのターゲティングとフォロワー数しきい値
+
+  本日、X API v2 の [Filtered stream](https://docs.x.com/x-api/posts/filtered-stream/integrate/operators) に、より精密なルールを構築できる 3 つの新しいオペレーターを追加しました。
+
+  - `from_affiliate_of:` — 特定ユーザーのアフィリエイトからの投稿に一致します (例: `from_affiliate_of:XDevelopers`)。
+  - `to_affiliate_of:` — 特定ユーザーのアフィリエイト宛ての返信に一致します (例: `to_affiliate_of:XDevelopers`)。
+  - `min_followers:` — 指定したフォロワー数以上のユーザーからの投稿に一致します (例: `min_followers:1000`)。
+
+  アフィリエイトオペレーターは組織のアフィリエイトアカウント全体の会話を追跡するのに、`min_followers:` はルールレベルでリーチの小さい投稿を除外するのに使えます。

+  ### 새로운 filtered stream 연산자: 제휴 계정 타게팅 및 팔로워 임계값
+
+  오늘, 더 정밀한 규칙을 만들 수 있도록 X API v2의 [filtered stream](https://docs.x.com/x-api/posts/filtered-stream/integrate/operators)에 세 가지 새로운 연산자를 추가했습니다:
+
+  - `from_affiliate_of:` — 특정 사용자의 제휴 계정에서 작성된 Post와 일치합니다 (예: `from_affiliate_of:XDevelopers`).
+  - `to_affiliate_of:` — 특정 사용자의 제휴 계정에 대한 답글 Post와 일치합니다 (예: `to_affiliate_of:XDevelopers`).
+  - `min_followers:` — 지정한 팔로워 수 이상을 보유한 사용자의 Post와 일치합니다 (예: `min_followers:1000`).
+
+  제휴 계정 연산자는 조직의 제휴 계정 전반의 대화를 추적할 때 사용하고, `min_followers:`는 규칙 단계에서 도달 범위가 낮은 Post를 걸러낼 때 사용하세요.
