+- We upgraded the core stack to React Native `0.83.4` and aligned related React dependencies.
+- We upgraded multiple React Native ecosystem dependencies for compatibility and stability (including CLI, navigation, animation, media, and platform modules).
+- We migrated from `react-native-vector-icons` to the scoped `@react-native-vector-icons/*` package set.
+- We updated `.gitignore` to more precisely exclude `node_modules` directories in specific locations.
+- We added a new dependency for `@shopify/flash-list` to support the migration from FlatList to FlashList.
+- We upgraded `react-native-tab-view` from 3.5.2 to 4.3.0.
+- Fix the iOS builds crashing when building with Xcode 26.
