Added

• JSI: Forward createValueFromJsonUtf8 in RuntimeDecorator (b5eec4e4f3 by @mrousavy)
• JSI: Run the With hooks around WithRuntimeDecorator::createArrayBuffer (82def6ea4c by @mrousavy)
• JSI: Forward String::length in RuntimeDecorator and WithRuntimeDecorator (be567d270c by @mrousavy)
• Yoga: Fix flex shrink explosion when the shrink total is a positive float residual (24a3be5f99 by @intergalacticspacehighway)

iOS specific

• SwiftPM: the build stops with a clear error when precompiled plugin frameworks and the Xcode project disagree, and the error says what to run. (a920e5db46 by @chrfalch)

Changed

• JSI: Use createError in JSError and forward it in RuntimeDecorator (0cca3a1f77 by @mrousavy)

iOS specific

• Build: Compile React Native's C/C++/Objective-C code with -O2 instead of -Os in Release, and Yoga and glog with -O2 in all builds, to match Android (60c817e925 by @chrfalch)
• SwiftPM: spm add and spm update write React Native's build settings to ReactNativeSPM/ReactNativeSPM.xcconfig and its build scripts to ReactNativeSPM/Scripts/, so a version bump no longer changes project.pbxproj. A configuration that uses its own xcconfig must now #include the generated file, and a target setting that hides React Native's value must add $(inherited). spm prints the exact fix in both cases. (cd89e98949 by @chrfalch)
• Text: Text without a background color no longer draws a transparent background (0bd33261d1 by @hryhoriiK97)

Fixed

• LogBox: Fix bottom notification appearance/touch targets on iPhone Duo (88a8bd23e8 by @huntie)
• Yoga: Keep the measured pixel size of text nodes when rounding to the pixel grid (fd5392494f by @intergalacticspacehighway)

Android specific

• Text: Fix text measured with the wrong width when fontVariationSettings are re-applied to a reused Paint (96518a8fb9 by @jkadamczyk)
• Text: Skip empty and fully hidden text decoration ranges (dbd5b3b770 by @Abbondanzo)
• Text: Fix crash drawing text decoration (underline/strikethrough) when a nested Text's span extends past a numberOfLines-truncated layout (ca8504b1ca by @lazerg)

iOS specific

• Image: Image no longer shows the image of a previous source after its native view is recycled (53bf98bf40 by @mattijsf)
• SafeArea: Fix views with a filter having their content offset by the safe area insets (fea820fa9b by @intergalacticspacehighway)
• StatusBar: StatusBar style and visibility work on iOS 27 for apps built with the iOS 27 SDK when UIViewControllerBasedStatusBarAppearance is YES. Custom root view controllers must return the RCTStatusBarAppearance values. (bd08dafc98 by @alanjhughes)
• SwiftPM: a project set up with skipped codegen no longer fails package resolution on ReactAppHeaders (e3aa9a1e19 by @chrfalch)
• SwiftPM: the build-time sync now runs again when a watched path that did not exist at the last sync appears. (c89f4120ac by @chrfalch)
• SwiftPM: keep line breaks in the scheme pre-action script so that the "Sync SPM Autolinking" pre-action runs. Run npx react-native spm update once to rewrite an existing scheme. (b8df948fd4 by @chrfalch)
