This is a beta version of Opera. Please use it only on properly backed up computers. It incorporates new features, improvements, and stability enhancements.

New features and improvements

Address field
An improved address field makes it easier to stay safe on the Web, and it now hides the complexity of long web addresses. It also provides more security information to help you stay safe when browsing; just click the badge for the website to see security information about the site you are visiting.

• All webpages get a badge to the left of the address field. The badge replaces protocols like HTTP, HTTPS, and opera:, which are shown only when focusing on the address field.
• Clicking the badge provides a easy overview of the potentially more complex security state of the current web page.
• Parameters at the end of web addresses are visually hidden until the address field is focused. You can disable this with opera:config#UserPrefs|HideURLParameter if you still want to see the whole address all the time.
• There is now a badge indicating that you are browsing with Opera Turbo on. Clicking this badge gives information about estimated data savings for the Opera Turbo session.

Auto-update

An improvement to auto-update now makes sure you have the latest extensions and Opera Unite applications.

Bookmarks bar

The Opera Bookmarks bar is located directly below the Address bar, and replaces the old Personal bar.

Enabling the new Opera Bookmarks bar

1. Open the "View" menu.
2. Select "Toolbars".
3. Click the check box next to "Bookmarks bar".

If you want the Bookmarks bar to show in the former location of the Personal bar

1. Open the Appearance dialog (Shift + F12) > "Toolbars".
2. Click "Show hidden toolbars while customizing".
3. Above the Address bar a Bookmarks bar appears. Click it once to mark it (a yellow outline will show around the bar).
4. Click "Placement" and select "Top" inside the Appearance dialog.
5. Mark the new Bookmarks bar located below the Address Bar, and choose "Placement Off".
6. Click OK.
7. The Bookmarks bar is now shown in the former location of the Personal bar.

Extensions

Opera extensions offer a way for you to easily add new functionality to your Opera browsing experience. Developers can easily create extensions using open standards (HTML5, CSS, JavaScript) and supported APIs. Opera extensions will be based on the W3C Widget specifications and this is being considered for an Open Standard effort.

• Extensions will now run on secure sites (HTTPS) by default, and we have added a privacy setting where you can allow/disallow extensions to run on secure connections or in privacy mode (disabled by default).
• Extensions now have a preferences page. Both the options page and privacy settings can be accessed from the extensions manager.

Some changes to requirements that will affect currently available extensions include:

• Extensions must include an access request for the pages you want to access with the background-process. You can do this by adding <access origin="http://example.com"> to the config.xml
• Extensions must include an index.html file in the package, or include a <content src="someStartFile.html"/> in the config.xml.
• Extensions must use broadcastMessage() properly:
• broadcastMessage() only takes one argument: a string or an object literal.
• So, use either broadcastMessage("hi"), or broadcastMessage({'say': 'hi' }

Mail panel

The Opera Mail panel has been improved with the following changes.

• Decide which sections to show, and in what order.
• Create folders to organize your mailing list and newsfeeds.
• Filters are now called labels. Existing labels, custom labels and saved searches (as labels) are now located together under the Labels header in the Mail panel. The old filters, labels, and saved searches are now merged into the new, more powerful labels
• In each category, (Attachments, Labels, Feeds, etc.) select which individual items to show and which items to hide.
• Feeds can now be displayed in the panel without the need to enable a mail account.
• The Mail panel automatically appears whenever you switch to a mail tab, and automatically returns to the previous state of the panels when moving back to a non-mail tab.
• POP accounts now have Inbox and Sent views for themselves.
• Multiple scrollbars are now changed to one global scrollbar for the mail panel. The scrollbar keeps section headers on top, which allows you to quickly scroll back up to them.
• All mail search fields are now consolidated into one. This enables you to search wherever you want, with the help of a new toolbar that appears when searching.
• You can save a search as a rule that will automatically label all the matching messages.

Plug-in loading

You can now set plug-ins to load only when you click on them, to significantly speed up browsing.

Presto 2.7 rendering engine

CSS3 Paged Media Module improvements
Support has been added for the object-fit and object-position properties.

• The CSSWG decided to rename the image-fit and image-position properties to object-fit and object-position, but the W3C CSS3 Module: Paged Media has not been updated yet.
• Since this CSS3 Module is not yet a specification, using these properties requires the addition of the Opera proprietary -o- prefix to each property. Opera recommends listing both formats in your style sheet, for example:

• -o-object-fit: meet;
• object-fit: meet;

CSS3 Text Module improvements

Renamed the -o-text-overflow property to text-overflow, and added support for ellipsis on multi-line blocks.

• The Opera -o- prefix is no longer required when using this property.
• See W3C CSS3 Text Module Section 7.3: Text overflow.

Encoding improvements

Big5-HKSCS support has been updated for the HKSCS-2008 encoding standard.

• See iana.org: Character sets.
• See ogcio.gov: hkscs 2008 summary.

HTML5 improvements

Support has been added for the following HTML5 items.

• Selection.selectAllChildren; see W3C HTML5 Section 7.6: The text selection APIs.
• HashChangeEvent event object; see W3C HTML5 Section 5.5.9: History traversal.

WebSockets support

Opera offers support for WebSockets which provide a way to communicate between script in a web page and the server in full-duplex mode with low latency. Opera supports version -00 of the WebSocket protocol (-76). WebSockets sets up one TCP connection and confirms that the server can speak WebSocket by doing a special handshake, after which the server and the client can send text messages over the connection at will, resulting in faster communication.

• References:
• WebSockets in Opera
• W3C WebSocket API

Search predictions

Search predictions from Google integrate into Opera's search field, and predict queries as you type, making searching quicker and easier. When using the search field or searching from the address field with the 'g' search keyword, Google search predictions will appear.

Speed improvements

Numerous advancements to the Carakan JavaScript engine have been made to improve Opera's speed and benchmark test performance.

Tab stacking

Opera invented tab browsing in the 1990s, and Tab stacking enhances tab organization in the user interface. Dragging one tab over another allows you to create groups of tabs. Now you can keep dozens of webpages open, organized, and under control.

User JavaScript

Support has been added for the W3C Web Storage API window.opera.scriptStorage property for user scripts alone.

• This property returns a Storage object as specified in the W3C Web Storage API, and is unique per script.
• User scripts can use this object to share presistent data across domains.
• Script storage objects currently do not fire storage events.
• The scriptStorage object has limited quota, defined in opera:config#PersistentStorage|UserJSStorageQuota.
• See Opera User JavaScript: window.opera.scriptStorage.

Visual mouse gestures

Mouse gestures is another genuine Opera innovation that was first introduced in Opera 5.10 in April 2001. Visual Mouse gestures help you learn how to control Opera with mouse movements. A new interface guides you through the available gestures, making it easier to learn and use them.

1. To see the new mouse gesture interface, hold (long press) the right mouse button down in any webpage.
2. Then, move the pointer in any direction and the interface changes to reflect the actions that can be performed with subsequent movements.
3. When you complete an action, a notification briefly shows what action you performed.
4. Once you learn your favorite mouse gestures and perform them quickly, the interface will not display.
