Good news for Opera users! Opera team has released Opera 11.64 version which is a security and stability update.
You might be wondering where is the 11.63 version? Why did Opera suddenly upgrade from 11.62 to 11.64 skipping 11.63. Don't worry! It's because 11.63 version was only released for Mac users.
According to Opera team, version 11.64 does not contain many bug fixes, but it is a recommended security update and it does fix some crashers and a bad nsl bug some people get on e.g Ebay.

Highlighted Features:
Opera Mail
- Two-lined message list: Opera Mail will now default to "list on the left, message on the right", with the newest message on top, and always showing message threads.
- Mail grouping: Opera will automatically group messages by date. You can also group them by unread status, by pinned status, or not at all.
- Cleaned up look: The mail toolbars are simplified, and icons have been redesigned.
- New settings dialogs: The "View" dropdown menu with all its sub-menus has been replaced by an overlay dialog that can be reached by clicking the "wrench" button.
- Pinning: You can now "pin" messages with one click in the message list or in the message headers, to mark a message for attention. This pinning is mapped to the IMAP \Flagged feature, so it corresponds to "starring" and "flagging" in other IMAP clients, and with Gmail's starred messages.
User Interface
- Additional refinement of the featherweight skin
- Improved Opera skin installation
- Improved plug-in install wizard
- Add icon in the address field to enable all plug-ins on the page when using "Enable plug-ins only on demand"
- New Add to Panel dialog to replace the old Bookmarks dialog
- Updated Hunspell component to 1.3.1

WOW! I think the browser wars just went to a whole notha' level. Absolutely beautiful. Great functionality, and best of all (to me anyway), it has a built-in ad blocker. I was using FireFox mainly due to the great ad blocking, but when you visit a web page in Opera, you just right click, apply the block content feature, and you can select what you want to block. GREAT! It's a lot faster too. I think this will be my main browser for a while.

Agree with Bobby!
Just finish installing and trying, its the best! Faster than ever. I try to use opera for some time and this beta version rocks! It is even faster than google chrome and safari! Love the new features too like tabs with screenshot and new and improved speed dial! Try it guys! Thanks again for the post VG!
