Thirteen-year-old Opera has been the perennial underdog in the browser wars, but the Opera 10 alpha brings some unexpected firepower to the battlefield.

@Snitlev: It was

I have just tested it. It passes the Acid3 test indeed (100/100), and page loading is done slighly faster than in 9.62. Can't wait to see a portable version of this build - perhaps it could be done by taking v9.62 Portable, replacing Opera.dll and renaming v10's opera.exe to op.com for the time being.

I have found the changelog:

Changes Since Opera 9.62

Presto

Opera 10.0 includes the Presto 2.2 rendering engine. Detailed changes since Presto 2.1.1 are listed below:

Rendering

Significant performance improvements
Added Web font support, allowing the download of fonts specified in font descriptors in @font-face at-rules; TrueType (TTF), OpenType (OTF), and SVG fonts are supported (demos)
Achieved 100/100 and pixel-perfect rendering on the Acid3 test
Pretty-printing of unstyled XML (using unstyledxml.css in the Styles sub-directory of Opera's installation directory)
Added support for CSS3 RGBA color values (demo)
Added support for CSS3 HSLA color values (demo)
Added support for the CSS3 color: transparent value
Added support for the viewport meta tag key
Improved HTML5 support, including end-tag and start-tag parsing, whitespace parsing, and DOCTYPE parsing
CSS files must be served with the correct MIME type ("text/css") in Strict mode or they will be ignored

JavaScript/DOM

New regular expression engine, which greatly improves performance on regular-expression-heavy pages such as the SunSpider JavaScript Benchmark
Added support for the W3C Selectors API
Renamed the objects returned by getClientRects() and getBoundingClientRect() to ClientRectList and ClientRect instead of TextRectangle and TextRectangleList, respectively
XMLHttpRequests will now trigger start-loading/end-loading events
Removed the proprietary window.setDocument method
Added support for the SVGElement.currentFps and SVGElement.targetFps properties to read and control, respectively, SVG frames per second
The load event for scripts is now sent after the script is executed rather than before
The load event is now sent to frame/iframe/object elements before it is sent to the document
A highlight will no longer be added when HTMLElement.focus() is called unless keyboard navigation is already activated

Other

Removed UTF-32 encoding support
User JS files will now be executed in alphabetical order rather than file system order
HTML5 canvas elements can now export images to the JPEG format
HTML5 canvas transforms are applied when building a path, not when painting it (this change is made to work like Mozilla)
The first ID (instead of the last) is now used on pages with duplicate IDs when navigating to fragment IDs
Added support for the altGlyph element in SVGs
Added support for 32-bit alpha in BMP and RLE-encoded BMP images
Implemented HTML5's algorithms for detecting charsets in HTML
The http://www.w3.org/TR/REC-html40 namespace is no longer treated as an alias to http://www.w3.org/1999/xhtml

User Interface

Auto-Update

Opera now includes the ability to automatically update itself when new releases become available. By default, Opera 10.0 Alpha 1 will simply notify the user about available updates. Users can specify that snapshots should be downloaded by enabling Download All Snapshots in opera:config. Users can also choose not to check for updates or to automatically install updates by going to Preferences > Advanced > Security and changing the "Opera update level" setting.

Inline Spelling Checker

Spelling errors are now indicated as you type via a red underline in input fields, Opera Mail, and Notes. The input field context menu includes spelling suggestions, as well as the ability to enable/disable the spelling checker and change dictionary languages. Opera 10.0 Alpha 1 includes a U.S. English dictionary. Only multi-line edit fields check spelling automatically by default.

Opera 10.0 uses the Hunspell dictionary format. Installing dictionaries will become easier before Opera 10.0 is released, but additional dictionaries can be downloaded and installed now by copying the dictionary files (*.aff and *.dic) to the local dictionary directory. Opera will recognize the additional dictionaries after restarting. The dictionary directory locations for each platform are listed below:

Windows: dictionaries (where is the 'Opera directory' in opera:about)
Linux/UNIX: /dictionaries/ (where is the 'Opera directory' in opera:about)
Mac: ~/Library/Application Support/Opera 10/Dictionaries/

Mail/News

Rich Text Message Composition

Opera Mail can now send rich text messages including inline images, styled text, links, and/or custom HTML. Forwarding and redirecting rich text messages now also works as expected. Rich text composition can be enabled by default for an account on the Outgoing tab of the account settings dialog by checking "Prefer HTML formatting". It can also be enabled on a per message basis in the message composition window.

Bold styling, italic styling, and underline styling can be toggled using Ctrl-B, Ctrl-I, and Ctrl-U, respectively.

Rich text message signatures are not yet supported.

Delete After X Days (POP-only)

Delete after X days automatically removes messages from POP servers after the specified number of days, which is particularly useful for users who have limited server space. This option can be enabled for POP accounts on the Incoming tab of the account settings dialog by checking "Remove from server after #days" (7 days by default). It's also possible to specify that only read messages and/or only fully downloaded messages should be removed.

Warning: Disabling the latter option is dangerous for those that use low-bandwidth mode, as messages that aren't completely downloaded will be removed from the server, making it impossible to retrieve the complete message.

Other Changes

When viewing a message, message subjects are now a text field again instead of a button
Added a Thread button to the message list toolbar
Added keyboard shortcuts for Go to Thread (D), Watch Thread (Ctrl-D), and Ignore Thread (Ctrl-Shift-D)
The encoding mismatch dialog has been removed

Miscellaneous

Network access for widgets is now opt-in. Thus, all existing widgets must be updated in order to have network access. All widgets on widgets.opera.com have been given Internet access. Network access is specified using the network attribute of the widget element. For instance, widgets that use <widget network="private"> will have Intranet access only. Widgets that use <widget network="private public"> will have Intranet and Internet access.
Dragonfly now selects the current tab automatically
Dragonfly now includes an HTTP inspector
Added support for TLS 1.2
SSL v2 and weak cipher support have been completely removed
Fixed numerous stability issues
Plugged numerous memory leaks

Changelog for Opera 10.0 Alpha 1 for Windows

**vDD+wR** · 16.12.08, 14:24

Just a new Version of Opera was released!

Opera 9.63 is a recommended security upgrade. Please see the Security section.
Opera 9.63 incorporates the Opera Presto 2.1.1 user agent engine.

Release Notes
Changes since Opera 9.62

Security

Manipulating text input contents can allow execution of arbitrary code, as reported by Red XIII. See our advisory.

HTML parsing flaw can cause Opera to execute arbitrary code, as reported by Alexios Fakos. See our advisory.

Long hostnames in file: URLs can cause execution of arbitrary code, as reported by Vitaly McLain. see our advisory.

Script injection in feed preview can reveal contents of unrelated news feeds, as reported by David Bloom. See our advisory.

Built-in XSLT templates can allow cross-site scripting, as reported by Robert Swiecki of the Google Security Team. See our advisory.

Fixed an issue that could reveal random data, as reported by Matthew of Hispasec Sistemas. Details will be disclosed at a later date.

SVG images embedded using <img> tags can no longer execute Java or plugin content, suggested by Chris Evans.

As it is stated that some security holes are fixed, I suggest to switch over to that version! (either by updating (if it works) or by un-/reinstalling the newer version

)

This is how it looks:
Opera/9.63 (Windows NT 5.1; U; es-ES) Presto/2.1.1

MsiZap can come handy if something goes wrong during the installation and leftovers from both the old and new versions remain.

Edit: just noticed that it seems to many people have updated that the server hosting Opera's "you're now using the latest version" page is overloaded!

"The server cannot respond to your request at the moment due to maintenance or capacity issues. We ask you to please repeat the operation later."

i love opera cause it is very flexible, have lotsa features and looked nice.

but i don't know why in my computer it sometimes used a lot of memories.

i use opera 9.60 but haven't encounter that kind of issues.

but sometimes the DHTML have to load for a moment to show.

@pi_1st: I have moved your other post here - that thread was about Opera 10.

The big RAM usage is normal - the more pages you open, the more memory Opera will have to use to store and display them. To reduce it a bit, try setting the memory cache size to 20MB instead of automatic. Disabling it isn't recommended; you can lose performance as the browser will need to read previously visited pages/elements from the hard drive, which is proportionally much slower.

Regarding your DHTML problem, try disabling Turbo Mode and following some ther basic performance-improving tips, which are documented in this same thread.

**pi_1st** · 28.12.08, 10:24

actually i disabled the memory cache alltogether and even the plugins. i like small and tight configuration.

but i think that is useless nowadays with all the machine generated 2.0 web pages. to many dynamic and interactive contents that i don't need, really.

I think it's better if you set the memory cache to at least 4MB instead of disabling it - you'll keep your HDD from spinning all the time when browsing.

Regarding plugins, I personally have them enabled globally, but have disabled them (and sometimes even JavaScript) for sites that overuse them and therefore make my whole PC slowdown when browsing them.

Disabling Java globally is also a good idea - you'll prevent LiveConnect-able Flash objects from unnecessarily loading the Java VM.

That's why Opera has a feature called "content blocking"

hmm i don't think it's quite true.. windows is still smart enough to cache some data from the hdd and even the hdd itself have some buffering mechanism

But by default Windows' cache's maximum size is around ~24MB (may vary from PC to PC), and it's used by all opened applications. You can imagine that with a lot of programs running it can "fill up" quite quickly, and therefore Windows will have to discard old elements (which could end up being whatever pieces of Opera's cache have been stored) in order to make room for disk-intensive apps.

That's a nice way of saving bandwidth

Make sure you're also using the IE7Pro addon!
