Ever since Digg purchased Instapaper from Marco Arment, the news aggregator super site has been adding new features to the somewhat neglected service to better compete with the likes of would-be challengers like Paper.

Continuing that trend, Instapaper for iOS was updated to version 5.1.5 today, bringing some new features, including support for Instapaper’s trending stories, a new send to Amazon Kindle function for subscribers, better AirPlay support, gestures and more.

Dots is a ridiculously fun, simple game that has taken iPhone and iPad owners by storm (and reduced my fingertips down to bleeding little nubs). In fact, the game has been downloaded more than 5 million times and played almost a billion times in less than four months.

Wouldn’t you like to get that on Android and Kindle Fire? Sure you would. Good news! It’s coming to Google Play today. And a new game mode is coming to all devices, including iPhones.

Instapaper has a new beta website, and it’s the biggest change to the whole read-it-later Instaverse since the app was bought by Betaworks. In short, it’s gorgeous for reading, and makes the management of your account quite a lot better.

Marco Arment has sold his popular read-it-later service Instapaper to Betaworks, the company that recently acquired and rebranded Digg. For years, Instapaper has been a widely-used web service and iOS app for saving links to read later in a clean layout without ads.

Don’t worry, Instapaper won’t be going anywhere. Arment and Betaworks plan to keep developing and maturing the service.
