Twitter has finally updated its Mac app with support for a few photo features the social network introduced over the past year.

Twitter for Mac users can now view and share tweets with up to four photos included, something introduced to iPhone Twitter users in May. The update also includes the ability to see and send photos in privately shared direct messages; iPhone Twitter users received this feature last December.

Twitter for Mac 3.1 is available for free on the Mac App Store. Full release notes below:

Twitter has been making a lot of improvements to its messaging experience in its mobile apps in recent months. It first introduced Direct Message syncing and other improvements back in July, and in recent weeks started rolling out the ability to receive direct messages from any follower (even those you don’t specifically follow) for a select number of users after testing it internally. Today, a new report claims that Twitter is planning further improvements to Direct Messaging and could as far as launching a standalone messaging app, much like Facebook Messenger.

The company plans to significantly update its direct-messaging product in the near future, according to multiple sources, bringing the long-buried feature to the forefront for the first time in years.

But Twitter’s new vision for direct messages will go further. It has kicked around the idea of launching a standalone direct-messaging application separate from the Twitter app, according to three people familiar with the matter. It is unclear, however, what form the final revamp of direct messages will take.

The report doesn’t provide much more info on Twitter’s plans, but does say it recently met with employees from MessageMe, one of the increasingly popular messaging apps that Twitter’s revamped DM service would attempt to combat. It also adds that we could see the new Direct Messaging app by the end of the year alongside a previously reported design overhaul.

After Unity announced in March that it was beginning to work with Facebook to help bring web games using the engine to the social network, Facebook announced today that it’s releasing a new SDK to bring 3D Unity games from Android, iOS, and the web to Facebook. The cross-platform SDK will also allow developers to easier integrate Facebook sharing and game invite features directly into their unity games across mobile devices and the web.

Facebook has a relevant and engaged audience of gamers that mobile developers can reach by publishing their games on Facebook, and the SDK makes bringing a mobile game to web as simple as writing one line of code. By filling out a few fields in the developer app and giving us the URL of your game object, you can bring your mobile game to a whole new audience of avid gamers on Facebook.

The SDK will also let Unity developers implement native dialogs for inviting friends, requests, and sharing through Facebook, and the company will be “helping more people find and play Unity games on Facebook by driving discovery of the Unity player with a custom install flow for the Unity plug-in.”

Facebook noted that a few games, including Cmune’s UberStrike, Madfinger’s Shadowgun:Deadzone, and Nival’s King’s Bounty: Legions, are already utilizing the new SDK.

The Facebook SDK for Unity is available here.
