This release comes with proper IPB 2.0.0 documentation so be sure to read "readme.html" which can be found in the root folder of the download archive. This file details which files have changed since PDR 4 and which bugs this release fixes.

What's new?
更新

There are over 75 bug fixes in this release which fixes nearly all of the major and intermediate problems with previous releases and we've only the minor ones to fix before the first release candidate. I've also been working closely with the DB drivers team to ensure that the first release candidate of Invision Power Board 2.0.0 allows seamless integration with other database drivers. We've finalized the new installer methods with multi-database abilities and gone through all the core code to ensure maximum compatibility. This means that IPB 2 will be able to take advantage of very clean MSSQL and Oracle database drivers when IPB 2 is in final release format.
这个版本中修复了75个bug，基本上修复上一个版本中所有主要的和较主要的问题，这样在公共测试第一版之前我们只剩下一些较次要的小bug还有待修复。此外，我一直忙于数据库驱动组的编写，以确保IPB 2.0.0的第一个公测版能与其他数据库驱动完美整和。我们已经完成了全新的具备多数据库兼容能力的安装程序的函数方法，核查了所有的核心代码以确保最佳的兼容性。这意味着IPB2正式版在最终发布之时将完完全全能使用MSSQL和Oracle的数据库驱动。

Upgrading from previous versions of IPB 2.0.0
从IPB 2.0.0之前的公共开发版本升级

The upgrade system is still being used and seems to be successful. Please note the new location of the 'ipb_templates.xml' file which is now in the forum's root folder to make it easier to remember to upload when upgrading. This is a vital step as it is used to rebuild your templates and add new template sections into the master skin when required.
升级系统看上去很成功，所以这次仍继续使用。请特别注意install/installfiles/ipb_templates.xml文件的新位置，现在已经被移到论坛的根目录中了，这样做是为了方便大家记住在升级时一定要上传这个文件。这一步至关重要，因为它被用来重建模板以及在需要时向默认皮肤中添加新模板。

Important: Make sure you upgrade the following files
重要: 请确认您升级了以下文件！！！
upgrade/index.php
upgrade/core/functions.php
ips_kernel/class_db_mysql.php

Upgrading from IPB 1.3
从IPB 1.3版本升级

There is no upgrade path to upgrade from IPB 1.3 yet (still). I really wanted to get IPB 2.0.0 as stable as possible before letting it loose on established boards with real live data. PDR 5 is the most stable release to date and I can now begin work on the 1.3 -> 2.0 upgrader.
目前为止仍然没有办法从IPB 1.3升级到2.0.0。我期望在正式发布并应用于现实的公众论坛之前尽量调试以使IPB 2.0.0日趋稳定。PDR5是迄今为止最稳定的版本，因此我将会开始制作1.3 -> 2.0的升级程序。

What's next?
下一步

There are a small number of minor bugs left to fix before we get to RC1. We hope to bring you RC1 early next week if we continue the speedy pace we've achieved over the past few weeks.
在RC1发布之前仍然有少数比较次要的bug等待修复。按照几周来的开发速度预计，我们希望在下周的上半周向大家提供RC1。
