Apple Releases iOS 26.5: New Update Adds Long-Awaited Feature For iPhone
出典: Forbes
Apple has officially released iOS 26.5, making it available for iPhone 11 series and all newer models, including the entire iPhone 17 lineup. Users can install the update by navigating to Settings, then General, then Software Update. The file size varies depending on the user's current iOS version, ranging from approximately 1.6GB for those already on iOS 26.4 to over 13GB for those updating from much older software versions.
One of the most anticipated features — a redesigned, more personalized version of Siri — did not make it into this release. Analysts had widely predicted its absence, and most now expect Apple to unveil the upgraded Siri alongside iOS 27 at the Worldwide Developers Conference, known as WWDC, scheduled for June 8. Despite some lingering public optimism, the company confirmed that the new Siri remains unavailable in this cycle.
The headline feature of iOS 26.5 is the introduction of end-to-end encrypted RCS messaging. This marks a significant step forward in cross-platform communication, as messages exchanged between iPhones and Android devices will, for the first time, benefit from strong encryption. Previously, only iMessage conversations between Apple devices enjoyed this level of security. Apple acknowledged the importance of this upgrade by publishing a dedicated Newsroom post, a relatively rare occurrence for the company.
It is important to note that encrypted RCS remains in beta and is not yet universally accessible. Its availability depends on carrier support, meaning not all users will gain access immediately. The rollout is expected to be gradual, with broader availability tied to telecommunications providers enabling the necessary infrastructure. Apple has signaled that this feature represents a long-term commitment to securing communications beyond its own ecosystem.
Beyond messaging, iOS 26.5 introduces several smaller but notable additions. A new 'Pride Luminance' wallpaper has been added, celebrating diversity with a vibrant visual design. The Maps application has received a 'Suggested Places' feature, which offers location recommendations informed by local trends and individual user activity. Additional enhancements specific to users in the European Union were also included, reflecting Apple's ongoing compliance with regional digital regulations.
日本語訳
Appleは正式にiOS 26.5をリリースし、iPhone 11シリーズ以降の全モデル(iPhone 17シリーズ含む)で利用可能となった。設定アプリから「一般」→「ソフトウェア・アップデート」と進むことでインストールできる。ファイルサイズは現在のiOSバージョンによって異なり、iOS 26.4からのアップデートは約1.6GBだが、古いバージョンからでは13GB超になる場合もある。
多くのユーザーが期待していた、より高度にパーソナライズされた新しいSiriは今回のリリースには含まれなかった。アナリストの多くはその不在を事前に予測しており、6月8日に予定されているWWDCでiOS 27とともに発表されると見ている。一部のユーザーの期待にも関わらず、Appleは新Siriが今サイクルでは利用できないことを認めた。
iOS 26.5の目玉機能は、エンドツーエンド暗号化RCSメッセージングの導入だ。これにより、iPhoneとAndroidデバイス間でやり取りされるメッセージが初めて強力な暗号化によって保護されるようになる。従来、このレベルのセキュリティはAppleデバイス間のiMessageのみが享受していた。Appleはこのアップグレードの重要性を認め、同社としては珍しいNewsroomへの専用投稿を公開した。
ただし、暗号化RCSはまだベータ版であり、全ユーザーがすぐに利用できるわけではない。利用にはキャリア(通信事業者)のサポートが必要なため、対応は段階的に進む見通しだ。広範な提供は、通信会社が必要なインフラを整備するペースに左右される。Appleは今後もAppleのエコシステムを超えた通信セキュリティに長期的に取り組む姿勢を示している。
メッセージ機能以外にも、iOS 26.5にはいくつかの注目すべき新機能が追加された。多様性を称える鮮やかなデザインの「Pride Luminance」壁紙が加わり、マップアプリには地域のトレンドや個人の利用履歴に基づいて場所を提案する「Suggested Places」機能が実装された。また、欧州連合のデジタル規制への継続的な対応として、EU在住ユーザー向けの機能強化も含まれている。
