Twitter has been hinting at changes on the way for third-party app developers, and now it looks like the company will be further making the case for its own app. According to release notes reportedly leaked through the App Store in iOS 6, the iPhone app will soon be updated to version 4.3 with a variety of new features. These include the ability to view interactive tweets with embedded content, see "select events" highlighted in the timeline, and set push notifications for individual users. The update is also said to have performance improvements and will employ the new Twitter logo on the icon. We're not sure if any of these changes will tempt users away from third-party options like Tweetbot, and there's still no indication of a similar revamp for the app on iPad, but we'll have to wait and see for ourselves when the update hits.
