Opera Software Readies Opera 11.51 Maintenance Release

When I look at the feeds in my RSS feed reader I cannot help but notice that the Opera browser is not receiving the same attention that the Firefox and Google Chrome browsers receive. This puzzled me for some time now and I figured that it is either caused by Opera's marketing of the browser, or the fact that Firefox and Chrome are more popular than Opera.

Opera Software regardless of that is about to release an update for the latest stable version of the Internet browser. You may recall that Opera is currently working on two different versions of the browser: First on Opera 12 the next big release and then on the maintenance release Opera 11.51 which all stable users can update to.

Opera 11.51 will be a maintenance release that improves the browser's stability on all supported platforms. Opera's plan is to release Opera 11.51 before the next big version Opera 12.00.

opera 11-51

The developers right now have released the release candidate of Opera 11.51 on the official Opera Desktop Team blog. This indicates that a release of the final version of Opera 11.51 is imminent.

The change log lists several crash fixes, for instance a crash on Macs when opening Opera Dragonfly, or a crash on all systems when marking e-mail messages as "not spam".

Opera users should not expect new features from the release, as it is only being pushed out to resolve issues that users have under Opera 11.50.

It needs to be noted that Opera 11.51 will upgrade Opera 11.50 on the system when installed. The release won't touch a Opera Next version that is installed on the system.

Most users should probably wait for the final release before they update their web browser. That is, unless they work with Opera and experience one of the issues that version 11.51 fixes.

Opera 11.50 users can download Opera 11.51 Release Candidate from the Opera website.

    Can someone tell me, how and why they release a major version ( 11.50 ) while it’s new skin has a ton of glitches? Maybe you’ll say, “it’s a minor problem,” but personally I find it unacceptable. And many other unfixed bugs… Like the thumbnails on Speed-Dial and Windows 7×64 ( blurriness ). I feel like Opera doesn’t respect me at all ( imo ).

    Also, Opera seems doesn’t follow the “trends” like Hardware Acceleration, Separated Processes etc and in terms of speed and memory managements, generally, is maybe left in last position ( fact ).

    You may find all these non-sense, maybe personally too… But do not wonder why the people don’t follow Opera. I could say many more reasons but anyway.

      Hardware acceleration, WebGL and HTML5 parsing are going to be included in Opera by the end of 2011.

    Hello Martin,

    You forgot one major thing in Opera 11.51 update. Read the Opera 11.51 changelog carefully under the Mac section at-


    In the changelog, the Mac section says-

    DSK-332671 (Implement support for Lion’s new Full Screen application mode)
    DSK-226117 (Links that open new tabs from pages with click event listeners will open tab in background)
    DSK-338150 (Freeze on dialogs and address field input)
    DSK-340688 (Crash when opening Dragonfly)
    DSK-343530 (Webfonts can cause a crash on Mac OS 10.7 ‘Lion’)

    See the first change, DSK-332671. Opera 11.51 will bring support for Lion’s new Full Screen application mode.

    As an Opera user, I am proud to announce that Opera will be the first browser to have support for Mac OS X Lion Fullscreen mode (Safari is excluded because it’s developed by Apple only).

    Stay tuned to write about the final release of Opera 11.51 after 3-5 days.

    “This puzzled me for some time now ”

    I haven’t been “puzzled”, I’ve been absolutely mystified for years now why this amazing Internet Utility Suite captures such a small market share. Maybe version 12 will push that percentage up. Hope so.
