12release时估计会有，因为12到AURORA频道时会全面转向VC2010

不会吧，真转到VC2010？

是的，前几天通告给Mozilla邮件列表的，不过只说了Firefox，其他产品并未提及

Firefox Support for Windows 2000 Coming to an End

For a number of years we've held off on updating our Windows toolchain to a newer version of Visual Studio, and in so doing preserved support for Windows 2000 and Windows XP RTM and SP1. Firefox developers and the 99.6% of our Windows users have paid a price for this support, though. Our developers have not been able to take advantage of new compiler features and have had to struggle to keep valuable optimizations from breaking -- including having had to back out and ultimately delay important new some features like SPDY.  Our users have have suffered a slower Firefox than would be possible as both direct and indirect results of moving to a more modern compiler.

So this week, after a few months of discussion and evaluation of the latest Firefox user numbers and the pros and cons of moving our tools forward, I've called for Mozilla to begin the process for ending support on those older Windows version. Next Tuesday or Wednesday, after Firefox 12 moves to Aurora, the Mozilla Release Engineering team will begin upgrading our Windows build systems to Visual Studio 2010.  With VS2010, we will no longer be able to build a Firefox that runs on Windows 2000, Windows XP RTM, and Windows Service Pack 1.

It's always a difficult decision to leave some users behind. The number of Firefox users on those OS versions -- less than one half of one percent of our Windows Firefox users, and the benefits to our development process and the hundreds of millions of Firefox users on XP SP2 and above, however, compel us to look forward rather than back.

If you are a Windows 2000 user, Firefox 12, released on June 5th, will be the final supported Firefox release. After that, your options are limited. Switching to Opera[1] is probably the best path forward.

If you're a Windows XP user still on RTM or Service Pack 1, I strongly urge you to install the free Windows Service Pack updates[2].

And finally, for Enterprises adopting the ESR[3], these older Windows versions will be supported for the length of the first ESR of Firefox. That works out to an extra 6 months or so before these Windows versions become unsupported.

所以我才说到时候12出来后很可能会同时推出X64版（2010的X64证明比较稳定，2005不行）

如果推出，palemoon/waterfox的x64版就没有使用的必要了
因为他们都没有解决x64版pgo编译的技术难题

12是最后一个支持的版本，应该从13的alpha开始转到vs2010，11 beta 12 aurora 应该还是vs_05

啊，我理解错了，原来以为整体迁移

扔掉windows 2000这个包袱  
就可以了  
12我现在更关心的是新的GC  
这货拖到现在了
