iTop 2.0.1正式发布，这基本上是一个bug修复版本，也提供了3个新增功能，具体版本更新描述如下文。
新的 REST/JSON API接口这个新的API接口能让其它第三方程序通过REST Web服务接口，来查询、修改和删除iTop系统里的数据。关于这个API接口的文档已经在iTop的Wiki站点上有了（[  /wiki]h /wiki[/url]）
更好的处理CRON后台任务周期性的后台任务新增能够更好的执行。这样就可以实现那些比较频繁，且重复执行的动作，例如：每隔几秒钟就读一下服务台的收件箱，看是否有人报告故障；或者能执行那些频率不太高的任务（如每天一次）；这些任务的执行对系统不会造成性能影响。
请注意：你必须在升级到这个版本的时候运行配置程序，否则后台任务执行功能就不会工作。
新的“Poser User”角色这个角色是“Portal User”用户的一个增强，它给一个用户通过web门户来访问他所属组织所有票单的权限。

#677 Cosmetics in the german localization (and a few other languages): first header of the config mgmt overview
#675 Error when drilling down on graph/pie/table with group by on a field that can be null (this case has been excluded)

#383 support negative numbers in OQL
also added support for MySQL bitwise operators (&, |, ^, <<, >>) and hexadecimal numbers (up to 64-bit).


Setup/installation fixes
————————
Compiler: typo preventing from setting the property ‘min_autocomplete_chars’ on an external key
Better error reporting when loading a module fails.
Sort the modules before processing them for dependencies, in order to obtain a predictable result independent from the order of the modules in the file system… hopefully… (should fix Trac#679)
Data model alternate options were not properly checked when upgrading (especially when selecting ITIL tickets)
Enable support of databases which name either is a reserved word or contains non-alphanumeric characters (i.e. itop-production).
Added support for creating symbolic links via the toolkit
Added more debug info in the setup.log about the detection of the previously installed modules
Enhancement: the expression of dependencies between modules can now use a complex boolean expression with a combination of “logical or” (||) and “logical and” (&&) instead of just a module name.
New internal flag for generating the delta: needed => define if not exists
Compiler: added the capability to redefine icons in xml
New way to compile the dictionaries, allowing for incremental modification via XML, also allows the filtering of the languages to install
Proper reset of APC cache upon compilation !
Experimental support of icon uploads…

Data model fixes
—————-
Correction to display IP address field for:
Physical Device
Network Device
Server
Storage System
NAS
Tape Library
SAN switch
Fix an issue that prevented the creation of Logical Interfaces
Add reconciliation keys for SLT in order to allow import for SLT having the same name
Remove wrong dependency to service_id on parent_request_id (for ITIL tickets)
Fixed typos in the sample data for the service subcategories
Make icons transparent…
All the overloads of DisplayBareProperties must return an array (otherwise a warning is issued and field validation will not work as expected)
The ticket class must be abstract!
Add “Employee number” to the list of possible reconciliation keys for the class Person.
Missing localized label for some problem management menus, when the Known Error Management module is installed without the Problem Management module


Miscellaneous fixes
——————-
Preserve POSted parameters on the login web page (useful when the session expires)
More readable edition for AttributeDuration
Properly record history of Hierarchical Keys
Fix for supporting the CSV export of big audit results.
Fix for making iUIPageExtension usable !
Fixed transparent background issues on the icons at the top-right of the main iTop page…
Allow printing lists fully expanded without the “pager” navigation. Also try to completely hide the main menu on the left when printing.
Properly serialize Emails with binary Attachments. Previously asynchronous emails with binary attachements were not working (they were queued but never sent).
Fix for the “Notifications” tab: use the polymorphism to let each trigger determine which object is “In Scope” and thus can potentially have notifications related to it
User rights:
- for link classes, if no grant has been given explicitely, then check if one of the remote class has a grant (mix of compile-time and run-time changes)
- fixed an issue: when looking for a grant into the hierarchy, the most explicit declaration (aka the deepest class) must be found first -> reorder the parent classes (new flag on MetaModel::EnumParentClasses
Prevent logoff problems depending on PHP’s session.cache_limiter setting…
- Enhancement: support for “target” in PopupMenuItems.. which was ignored before
Fix for reconciliation by id (Advanced Mode) -reintegrated from branch 2.0
Silently discard unknown attributes in object templates (in case some modules have not been installed)
Fix the auto-resize (fit) of the dialog’s content when picking up a value using the magnifier button on an external key.
Cleanup of the log output. No need for such verbosity now that we are approaching the release.
