This release adds a variety of new features, a new skin designed by [[Jon Hicks (designer)|Jon Hicks]], increased standards support, and a new application icon to Opera. Opera 10 was touted as being 40% faster than Opera 9.6, with the upgrade of Opera's rendering engine to [[Presto (layout engine)|Presto]] 2.2.15.<ref>{{cite web

==New Features==
===Engine Improvements===
Opera 10 uses Presto 2.2.15 which improves (caca) rendering speed, adds support for web standards such as RGBA/HSLA color, and improves existing support for web standards. This version of Presto passes the [[Acid3]] test.<ref>{{cite web

===Opera Turbo===
Opera 10 automatically detects when a connection is slow, and offers to [[compress]] web pages via [[Opera Software ASA|Opera Software]]'s "Turbo" servers, thus reducing download size. Because web pages are compressed, page loading times on slow connections are dramatically improved, and less data is consumed. However, owing to said compression, images will be displayed at significantly reduced quality. Opera Turbo is designed to be used by people that are using a slow connection, or that have limited bandwidth.<ref>{{cite web

===Opera Unite===
Originally it was planned to release [[Opera Unite|Unite]] in Opera 10.0, however its release was delayed until Opera 10.10. Unite is essentially a home server, on which many applications can be run. Opera provides a [[Domain Name System|DNS]] service at [http://operaunite.com/ operaunite.com], however this is optional. Unite Applications are based on existing web technology, and can be written by third parties. The following official services are to be included with Unite:
* '''Home''' - Lists available applications currently running on your computer, as well as providing an overview of the Applications used by friends
* '''File Sharing''' - Allows a folder containing files to be made available online and easily shared
* '''Fridge''' - Allows people to leave you public notes, which can be view by you and others on your virtual fridge
* '''Media Player''' - Allows a folder containing audio files to be presented as a web page, where the audio can be streamed from your computer
* '''Messenger''' - Allows one-to-one chat with any of your [[My Opera]] friends who are also using Unite
* '''Photo Sharing''' - Allows a folder containing pictures to be presented as a collection of galleries
* '''Web Server''' - Allows you to serve a web site directly from your computer

===New Skin and Interface Improvements===
Opera 10 has a new skin, designed by [[Jon Hicks (designer)|Jon Hicks]], famous as the original renderer of the Firefox icon. Originally, a new skin was not planned for Opera 10, but as various icons were updated, it was decided that an overhaul was appropriate. Many complaints with the previous skin of 9.5 and 9.6 are addressed.<ref>{{cite web

|date=16 June 2009
}}</ref> Overall, the skin uses less screen space, and is not as dark as the previous one.

===Visual Tabs===
Previous versions of Opera showed a thumbnail of the page when hovering a tab. In Opera 10, it is possible to display this thumbnail as part of the tab, allowing quick navigation. Visual tabs use an image thumbnail rather than the default [[favicon]] and description. Displaying the visual tabs can be achieved via dragging the toggle line between the address bar and the tab bar. Visual Tabs can be placed on the bottom, top, left, and right section of the browser window.

===Speed Dial Improvements===
A new configuration dialogue has been added to the Speed Dial, which facilitates easy customization of this feature. A background image can now be chosen independently of the skin, and it is possible to select a custom number of speed dials, ranging from 2*2, to 5*5 tiles.

===Webmail Integration===
Opera 10 adds the option of opening mailto: links in webmail interfaces. Op. The following providers, Gmail, Yahoo! Mail, and Windows Live Mail from the default selection will added with Opera's default providers, Yandex, Fast Mail, Opera Mail, and Mail.ru when they begin to support Opera.

===Inline Spell-Checker===
Previous versions of Opera contained an on-demand [[spell-checker]] based on [[GNU Aspell|Aspell]]. Opera 10 introduced an inline spell checker based on [[Hunspell]]. This is available in multi-line text areas and in the mail client. As you type, misspelled words are underlined, and can be corrected via a right click menu. The US-English dictionary is included, and there is an interface to download additional dictionaries from within the browser. This inline spell-checker has support for 48 languages.

===Auto-Update===
Previous versions of Opera were criticized for not including a built in updater. Previously, users were notified of an update, whereon they were directed to a download page. Owing to this laborious update process, many users ignored security updates. Despite an excellent security record, many Opera users were vulnerable to exploits. Auto-Update is available for Windows and Mac only, while on Linux systems, updates are managed by package managers.

===HTML Mail Compose===
Opera 10 introduces the ability to author [[HTML]] email in Opera's mail client. Previous versions were capable of displaying HTML mail, but widely criticized for only allowing plain text composition. When HTML mail composition is selected, a toolbar appears allowing selection of common options, such as font, font size, bold, italics, underline, links, images, etc. Along with inline spell-check, Opera has addressed the two largest barriers to adoption of its mail client.

===Automated Crash Reporting===
To facilitate improvements to stability, a crash reporter has been added in Opera 10. If the browser crashes, a dialogue will appear asking if a crash log should be uploaded. Here the last displayed web page is automatically detected, and the user is presented an opportunity to provide details of the crash and/or their email address for further contact.

===Opera Dragonfly Improvements===
Opera 10 received improvements to Opera's [[web page]] debugger, [[Opera Dragonfly]].
These improvements include:

* '''Improved UI and workflow''': The [[UI]] is now more compact and intuitive, and one of the biggest Opera Dragonfly usability issues has been fixed — Opera Dragonfly now selects the active tab or window in the browser automatically, cutting out a few steps required to start [[debugging]].
* '''Live CSS and DOM editing''': Opera Dragonfly’s [[CSS]] editing abilities have been enhanced, and DOM editing is now supported, allowing text nodes and [[DOM]] attributes to be edited, added or removed.
* '''Improved error console''': This lets you see, filter and log any errors in your scripts, pointing to the exact position where the error occurred.
* '''Support for multiple languages''': Opera Dragonfly has been translated into 37 different languages.
* '''Enhanced [[Breadcrumb (navigation)|breadcrumb]] trail''': Allows you to navigate the DOM tree more effectively.
* '''Network Inspector''': This gives an overview of all the resources that were requested by Opera for the active debugging context. You can break down each request to show the request summary, raw request and the request and response headers.
* '''Remote debugging''': Using Opera Dragonfly, you can debug pages on Opera Mobile 9.7, or on any other browser using Presto 2.1 or later.

===User Agent String===
Both today and in the past, browser sniffing has been a big problem for Opera, a minority browser. As many older websites only detect the first character in the browser version, Opera 10 would be detected as Opera 1. For this reason, Opera 10 identifies itself as ''Opera 9.80'', and appends to the string ''Version/10.00''.<ref>{{cite web

The full string on Windows XP (English) is as follows: <br />
* Opera/9.80 (Windows NT 5.1; U; en) Presto/2.2.15 Version/10.00

===New Application Icon===
[[Image:Opera icon comparison.png‎|thumb|right|170px|Opera 10 icon (right) compared to the previous version icon (left)]]
The new [[icon]], designed by [[Oleg Melnychuk]], has been welcomed by most. Opera was careful to preserve branding, and the icon is still a large, red 'O'. However, the shadow has been made smaller, and the 'O' thickened, reshaped, and given a matte 3D look.<ref>{{cite web

Overall critical reception has been very positive. On day of release, Opera 10 received such attention that [[Opera Software ASA|Opera Software]]'s servers struggled with the high demand, and as a result were unavailable for parts of the day.
After one week since Opera 10's launch there have been 10 million downloads.<ref>{{cite web
