Opera 10

Opera 10 is a version of the Opera web browser.


This release added a variety of new features, a new skin designed by Jon Hicks, increased standards support, and a new application icon to Opera.


Opera 10.00 was touted as being 40% faster than Opera 9.6, with the upgrade of Opera's rendering engine to Presto 2.2.15.


In comparison to 9.x versions, Opera 10.50 uses Presto 2.5.22 which improves rendering speed, adds support for web standards such as RGBA/HSLA color, border-radius, and CSS transitions, and improves existing support for web standards.


Opera 10 automatically detects when a connection is slow, and offers to compress web pages via Opera Software's Turbo servers, thus reducing download size.


Opera Turbo could also be used to access websites that are blocked on a school or work network, because the browser sends the request to the Opera servers when using this feature, preventing the network from understanding which website it is trying to access.


Opera 10 introduces the ability to author HTML email in Opera's mail client.


As many older websites only detect the first character in the browser version, Opera 10 would be detected as Opera 1.


Originally it was planned to release Unite in Opera 10.00, however its release was delayed until Opera 10.10 to allow further stabilization.
Linux skipped 10.5× altogether, meaning the release of Opera 10.60 brings Windows, Mac, Linux and FreeBSD releases back into sync for the first time since Opera 10.10.
