准备升级主站varnish到3.0.1，主要看上最后一句了

Summary of changes from 3.0.0 to 3.0.1

    • Objects with grace and keep set were mistakenly seen as candidates for the shortlived storage, but would not be cleaned up quickly, something that manifested as if there was a memory leak. This is now fixed.
    • When multiple clients were waiting for an object, all clients would be woken up when an object became available, leading to stuck threads. This has now been fixed
    • A bug in how XML entities were handled with ESI has been fixed
    • The documentation has seen numerous updates
    • varnishncsa is now more stable and has support for showing arbitrary request and response fields、

期待varnishncsa有更好的表现

wordpress 3.2.1放出

WordPress 3.2.1 2011 年 7 月 13 日, Jiehan 现在，在 WordPress 3.2 版本下载量达到一百余万次之后，我们发布 WordPress 3.2.1。这个维护版本修复了一些服务器上可能发生的 JSON 不兼容问题，同时还包括控制板样式和 Twenty Eleven 主题的小修补。 要查看所有修改，请访问中文 Codex 文档页面、更新历史（英文）或解决的工单列表（英文）。 下载 3.2.1，或在您站点后台的“控制板” → “更新”菜单进行升级。

wordpress已出3.2版本

WordPress在美国独立日发布了3.2正式版，这是3.1版本发布一个月，下载量突破1500万后的又一个主要版本，新版带来了更快的速度和更轻量级的代码，并带来了HTML5构建的Twenty Eleven主题，在写文章的同时还可以以全屏方式进行。

火狐推5.0正式版–跳墙的利器，大家更新吧

         在火狐4.0发布三个月后，开源机构Mozilla提前在服务器上传Firefox 5.0最终版的下载链接。目前，从测试人员反馈信息得知，Firefox 5已相继释出了Beta、RC发布候选版（5.0b7）和Final builds。而下一代火狐6.0将在5.0推出两周后进入Beta测试。
         之前安装了火狐4.0的用户会在24-48小时内收到需要更新的升级通知，官方欢迎插件开发者能在新版本中测试插件的运行情况。为了配合新版本的发布，Mozilla官方计划终止对Firefox 3.5的支持服务，强制用户升级到3.6.18.

据Firefox发布主管Christian Legnitto透露，新版Firefox 5.0的外观和使用体验与4.0颇为类似，但仍然带来一系列亮点功能：
——添加CSS动态技术支持；
——防追踪功能升级，加强隐私保护；
——提升Canvas、Javascript、内存和网络性能；
——提升对Html5、XHR、MathML、SMIL等主要标准的兼容性和处理效果；
——新增拼写检查；
——针对Linux用户加大对新版系统的桌面环境的支持；
——取消WebGL内容在多个数据域的执行能力，稳定性更好；

WordPress.org 密码重置

2011 年 6 月 22 日, Jiehan

今天早些时候，WordPress 开发团队注意到部分热门插件（AddThis、WPtouch 及 W3 Total Cache）的代码库中出现可疑的代码提交，且包含伪装巧妙的后门。开发团队断定，这些代码的提交操作并非出自作者之手，因此将代码库回滚，并为这些插件推送更新。同时开发团队也关闭了插件代码库的存权限，继续查找其他可疑内容。

开发团队尚在研究具体情况，但作为预防措施，他们决定强制所有 WordPress.org 用户重置密码。用户在使用论坛、trac 或对插件或主题提交代码之前均需重置密码。（bbPress.org 与 BuddyPress.org 也受到影响）

作为用户，请确保同一密码不用于多个服务。开发团队还奉劝用户不要重置为原密码。

其次，如果安装有 AddThis、WPtouch 或 W3 Total Cache 并有可能在过去一天内进行了更新，请确保访问更新页面并升级各插件为最新版。
