ITHome reported on October 27 that Apple today pushed the macOS 27.2 update (build number: 26B123) to Mac users, 28 days after the last official release.
It should be noted that due to caching issues in the configuration of Apple's regional node servers, some locations may detect the upgrade update with a slight delay, generally within half an hour, and it won't take long.
ITHome consulted public sources and compiled the main changes in this update as follows:
Expanded Siri AI languages: Added support for French, Japanese, Korean, Portuguese, and Spanish; together with the existing English, six languages are now supported.
Siri contextual memory: Siri AI can retain useful context from previous conversations and draw on broader personal contextual information to answer questions, for example by referring to previously recommended content or cross-app information.
Smart suggestions in Messages: Based on chat context, it provides quick action suggestions in apps such as Calendar and Reminders, for example directly creating an event or a reminder.
Siri data scope and privacy controls: Siri AI can reference information such as photos in Messages, calendar participants, voicemails, Safari history and Reading List; meanwhile, an Excluded Apps setting is provided, allowing you to choose app data that Siri, Search, and system suggestions cannot access.
Interface and experience adjustments
Adjusted brightness and volume sliders: When adjusting with the keyboard, the sliders now change in small, noticeable steps.
Apple Music icon update: The app icon has changed from a red-and-white color scheme to a new black-and-white / blue design, as part of the Apple Music brand visual update.
Underlying preparation for touch: The system has added code related to touch gesture recognition in apps such as Safari, Photos, Notes, and Quick Look; Apple has not officially introduced these features in the release notes, so for now they appear more like underlying preparation for future touchscreen Macs or Sidecar scenarios, rather than new features users can directly use.
