In an update released today, Twitter brought direct message sync to its official iOS app. As explained by the company in the release notes, reading a DM in Twitter for iOS will now automatically mark it as read in Twitter for Mac, the Twitter website (both desktop and mobile versions), TweetDeck, and Twitter for Android.

It’s not clear whether DM sync will ever be made available for third-party developers through the API; right now, it’s a nice plus for users who receive several direct messages on a daily basis and use the official Twitter apps. It’ll also be interesting to see if Twitter will eventually consider syncing timeline position across apps – something that third-party apps like Tweetbot and Twitterrific are capable of using solutions like iCloud or Tweet Marker.

Twitter for Mac has also been updated to version 2.3 today, adding a Connect timeline for viewing tweets that have been retweeted or favorited, as well as new followers. Interactions can be viewed with notifications in real time, and the app also supports DM sync.

Last, in a blog post, Twitter details the search improvements they’ve made to simplify user discovery and retrieve new tweets:

For Android, iPhone, iPad and mobile.twitter.com, we’re making more improvements to search results. Now when you search for people on Twitter, you may see an expanded user result that shows a full bio. This account preview makes it easier and faster to find and learn more about the accounts you’re looking for. And if you swipe the preview to the left, you’ll find similar accounts –– for example, if you search for the MLB, you’ll see suggestions for ESPN, Ken Rosenthal, and other MLB-related accounts. Additionally, a new in-app indicator in search results will show you when there are new Tweets for your query, making it easier for you to stay up to date on the latest Twitter conversation.

Twitter 5.8 is available on the App Store; Twitter for Mac 2.3 is available on the Mac App Store.
