Opera Moves to WebKit
What Does this Mean for Developers?Extension developers may be concerned about this switch because it will probably mean a lot of extra work. But never fear! Opera will soon release a tool to convert existing OEX extensions into a format friendly to the new Chromium-based Opera. There will also be conversion tutorials and developer forums.
Web developers shouldn't be affected much, but there are two things to keep in mind:
- Chromium doesn't have built-in support for for H.264 or MP3 codecs. Check media support with HTML canPlayType, but the simplest method is to encode codecs in both WebM and H.264 with two <source> elements.
- The window.opera object will not exist in the new Chromium-based Opera.
What Does this Mean for Users?
In short, Opera users will notice better site compatibility--especially on mobile sites, which are usually only tested on WebKit browsers. The switch to WebKit has been described as a purely "under the hood" change, so users shouldn't notice much difference.
