Apple has added references to an unreleased app, called “Invites,” which appears to streamline scheduling and meeting invitations. Additionally, the update resolves bugs affecting Genmoji customizations and improves the Writing Tools API for third-party apps.
macOS 15.3 and iPadOS 18.3 Enhancements
macOS Sequoia 15.3, with build number 24D5055b, focuses on system stability and performance improvements. For iPadOS 18.3, developers can expect similar refinements as its iOS counterpart, with the shared build number indicating close alignment in features and fixes.
Updates for visionOS 2.3

Apple’s Beta Testing Advice
Apple and experts strongly recommend that beta versions are not installed on primary devices. Beta software can occasionally lead to performance issues or data loss. Developers should use secondary devices and ensure they back up all critical data before testing.
Looking Ahead
As Apple continues refining its operating systems, these updates highlight its commitment to improving user experience across devices. The final public release of iOS 18.3, iPadOS 18.3, macOS 15.3, and visionOS 2.3 is anticipated in the coming weeks.
