We've almost completed IPB 2.0.0 PDR 4 which completes the database abstraction and rounds off some features.
IPB 2.0.0 公共开发第四版已经基本完成，数据库抽象层和一些其他功能在该版中都已完成。

This release took much longer to complete than expected due to the enormous task of going through each IPB source file (160+ files) and manually extracting the SQL statements to either put them in the queries file or convert them into the database abstracted methods. This is a vital step for allowing IPB 2 to be ported to different database systems and although it's taken a great deal of time, it's entirely justified by the flexibility the system allows.
完成这个版本比预期的时间要长好多，主要是由于这是个浩大的工程，几乎涉及了IPB的每一个原文件(160多个文件)，而且要手动地将SQL语句提取到查询文档中，同时还要将它们转换成数据库抽象方法。这是使IPB 2可以移植到不同的数据库系统上的至关重要的一步，尽管耗时巨大，但是作为提高整个系统的灵活性和兼容性是尤为值得的。

Other items finished in this release are as follows:
本版中完成的其他一些项目:

* Skin import / export routines (export XML templates and XMLarchive image sets)　皮肤导入/导出程序(导出XML模板及XML存档的图片)
* Languages import / export routines (export XML language file)　语言导入/导出程序(导出XML语言文件)
* Re-designed mini-profile card (more info, better layout)　重新设计了袖珍资料卡(mini-profile card)，可容纳更多信息，排版更合理

I've also fixed a few of the larger bugs so far (permission mask addition / removal, moderator addition, etc) and although we have many bugs left to fix before we get to RC1 status we're confident that they are minor and as such won't take long to work through.
同时也修正了一小部分目前为止比较大的bug(权限蒙板添加/删除，版主添加等等)，当然在RC1之前仍然有很多bug等待修正，相信那些都是相对较次要的bug，不会耗费太多时间的。

Latest Release Date Estimates
新版本发布日期预计

PDR4 (next beta release): Wednesday 2nd June
RC1 (first supported release): No specific date - around the middle of June
公共开发第四版(下一个beta版本): 6月2日 星期三
公测第一版(开始提供支援): 日期未定 - 大约在6月中旬左右

Please note that these dates are only estimates and should only be used as a guide. They are subject to change without notice due to the unpredictable nature of software development. Put simply: they are dates that seem reasonable based on the current speed of development.
以上是预计日期，仅供参考。

What's left to do?
尚待完成的任务

We're nearly at the stage where IPB 2 reaches release candidate quality. The full feature set is now implemented (apart from a few minor tweaks and enhancements).
离预发布版本已经非常接近了。所有功能均已植入。

Skins and Languages
皮肤和语言

As mentioned in other announcements, the skins and language sets are not complete and will receive an overhaul during the development cycle. As a rule of thumb, the skins and langauges will not be complete until PR 1 (RC 1).
首要原则，皮肤和语言至少要等到公测第一版时才会完成。

Upgrading to PDR 4 from PDR 1,2 or 3
从公共开发第一、第二或第三版升级到第四版

We have initiated our new upgrade system and a new upgrade module will be written for PDR 4.
新的升级系统已经启用，将为第四版写一个升级模块。

Upgrading from 1.3 to 2.0.0
从1.3升级到2.0.0

There is currently no upgrade path from 1.3 to 2.0.0. We plan on writing the upgrade script for around PDR 4 (Beta 4) - possibly just after. Until then please don't try and import a 1.3 database into 2.0 - it simply won't work.
目前来说不能升级。计划在公共开发第四版的时候写升级脚本，在此之前请勿尝试将1.3的数据库导入至2.0，结果只能是不能用。
