Numeric X Axis — Expo Charts
PR #41236

Added numeric x-axis support to the Expo UI Chart component — enabling time-series and continuous-axis charts. Updated ChartDataPoint in TypeScript to accept string | number, added transformDataPoint() for Swift interop, and extended all chart mark types (bar, area, line, point, rectangle) in SwiftUI to handle both categorical and numeric axes.

Android Color Crash Fix
PR #44023

Fixed an Android crash when passing CSS-style rgb()/rgba() strings to props decoded as android.graphics.Color — extended ColorTypeConverter in expo-modules-core to parse these formats, and added Robolectric unit tests to lock the behavior including whitespace variants.

03
SecureStore Docs Fix
PR #40729

Fixed a documentation inconsistency in expo-secure-store — the docs incorrectly stated that data is deleted on app uninstall, but iOS Keychain data persists after uninstallation by Apple's design. Clarified the real behavior to prevent developer confusion around sensitive data persistence.

File System Docs Fix
PR #41272

Fixed missing documentation for expo-file-system's bundleDirectory — the docs mentioned bundled asset access but provided no working examples. Added clear examples for reading bundled resources (e.g. using arrayBuffer()) to resolve real developer confusion.
