Google has announced the first official update for its Chromecast, the dongle for the TV currently available for $35 in the United States. The Mountain View group has shared less information about the changes and published a very short post on the Chrome Releases blog.

Today, we are pushing a bug fix update to Chromecast devices to improve performance, reliability and security. The update will roll out over the next few days and will happen automatically; users do not need to take any action.

So there are no new features in addition to those, already described at least for now. It is an over-the-air update that has its sole purpose to fix some bugs found during the early days of marketing the device. The dongle was announced last week, and set a record sale and sold out within hours after its debut on the market.

Meanwhile, Hulu, HBO and others have expressed interest in app for Google Chromecast. Hulu has revealed that they will join the list of services supported by Chromecast soon, alongside Netflix, YouTube, Google Play, and Chrome. Meredith Kendall, a spokeswoman of the platform, told Variety “At Hulu, we’re constantly innovating to provide our users with access to their favorite TV shows anytime, anywhere, on any device.”

HBO also said something similar. While Vimeo, Plex and Redbox Instant are reportedly interested into making their mobile apps compatible with Chromecast.
