As usual, the HTML5 space was fairly busy this past week, with two major updates from the folks over at Opera.

Indeed, Opera got the ball rolling this week with the news that TiVo’s (News – Alert) Roamio DVR platform now supports the Opera Devices SDK. This SDK is an extensible TV platform that enables developers to create HTML5 apps specifically for TiVo. In other words, TiVo users can soon expect a slew of new custom apps with full Web browsing capabilities and entertainment options.

If that wasn’t enough, Opera followed up with a new version release of its desktop browser — an event that happened to coincide with the company’s 18th birthday. The 16th version of Opera boasts hundreds of bug fixes, improved performance and, most importantly, HTML5 support. Other improvements include the ability to share users’ locations with trusted websites, a form auto-filler and support for jump-lists in Windows.

Meanwhile, in HTML5 gaming news, software developer New Game Town was one of the first HTML5 developers to make its games available in the Amazon store this week. Specifically, New Game Town brought two of its most popular titles — “True Night,” a vampire RPG and “Cage Fighter,” about the competitive fighting world — to the Amazon Appstore. This means the games are available on the Kindle Fire and through the Amazon Appstore for Android (News – Alert).

There was HTML5 news relating to digital comics this week as well as ComiXology, which provides a cloud-based digital comics platform that facilitates seamless comics discovery, introduced an HTML5 upgrade to its Retailer Digital Storefront program. This program allows printed comic book sellers to turn a profit. With the new HTML5 version, users can now use both mobile devices and PCs to buy digital comics from retailers of their choice.

That’s all for this week, but head over to the HTML5 Report for more news in this space.
