  "Additional generic AddComponent overloads"

- Applied Ido Samuelson patch fixing IOC-85
  "IKernel to support generics to add/resolve components."

- Refactored proxy options support. Now you can use the attribute 'marshalByRefProxy' 
  on the external configuration, or the ComponentProxyBehaviorAttribute

- Fixed IOC-79
  "Kernel.GetHandlers(Type) does not consider generic handlers when satisfying the type"

- Updated StartableFacilityTestCase to correctly demonstrate the facility and
  added a unit test to demonstrate IOC-80

- Updated TypedFactoryFacility to not require a target instance
  when proxying.

- Added Windsor proxy support to create proxies without targets.

- Removed relationship between ProxyOptions and ProxyGeneration options
  and moved ProxyOptions into the MicroKernel.  ProxyGeneration options
  are created from the ProxyOptions and will probably need to be updated
  as facilities demand more proxy generation customizations.

- Added ProxyOptions to allow facilities to easily add proxy interfaces
  without having to create custom proxy factories.  The ProxyOptions
  are obtained via the ProxyUtil.

- Fixed IOC-65
  "DictionaryConverter should use the alternate overload of the 
   PerformConversion method in order to support dictionaries that contain 
   custom types"

- Moved ProxyComponentInspector from Castle.MicroKernel to here and added
  support to supply ProxyGenerationOptions on a ComponentModel basis.  This
  provides the needed ability to provide proxy options in facilities.

- Fixed IOC-69 - DefaultDependencyResolver issue with Service Overrides.

- Added ComponentProxyBehaviorAttribute and ComponentProxyInspector 
  to control the creation of component proxies.

- Applied patch by Bill Pierce that

-- Introduces the WebUserControlComponentActivator

-- Introduces the KeySearchNamingSubSystem

-- Allows you to associate a custom component activator using
    1. componentActivatorType on component node
    2. ComponentActivatorAttribute

-- Allows you to create and configure child containers 
   through the configuration, using

  <configuration>
    <containers>
        <container name="child1">
          <configuration>
                <facilities>
					...
                </facilities>
          
                <components>
					...
                </components>
                
            </configuration>
        </container>
    </containers>
  </configuration>

  "Provided an Implementation for BinaryTreeComponentName.Remove"

- Applied patch by Adam Mills fixing IOC-39
  "Fix for Null Reference when accessing empty BinaryTreeComponentName"

- Fixed IOC-35 
  "Add bootstrap section to configuration file"

- Fixed issue where KeyAlreadyAdded exception would be throw for 
  components accepting two parameters of the same type, without overrides

- Fixed IOC-36 
  "Transient components with multliple constructors throw 
   unresolved dependency exceptions."

  Removed best candidate reference, as the kernel is dynamic it should
  not cache best constructors as components can be added or removed
  at any time
  
  Removed Points from candidates, as in a multithreaded scenario
  this would lead to failures
  

- Fixed IOC-34 
  "Cannot use types having their own base type as constructor argument"

  See revision r2787

- IOC-32, Support generic collections. 
  Supported collections are: ICollection<T>, IList<T>, List<T>, IDictionary<K,V>, Dictionary<K,V>, IEnumerable<T> 

RC 3
====
 
- Applied patch by William C. Pierce <wcpierce@gmail.com> adding PerWebRequestAttribute

- Added setter to ReleasePolicy property

- Applied Curtis Schlak's patch fixing IOC-30
  "Add overload to Windsor AddComponent to specify the Lifestyle"

- Refactored AbstractHandler to use IDependencyResolver

- Dependencies can be resolved now in three levels:

  * CreationContext (which now implements ISubDependencyResolver)
  * IHandler (which now implements ISubDependencyResolver)
  * IKernel which is the normal flow

- Implemented IoC-29 using a different approach

- Renamed IKernel.AddComponentWithProperties to AddComponentExtendedProperties.
  The old method name misled the programmer about its purpose.

- Added a PerWebRequestLifestyleManager which creates at most one instance of
  an object per web request.  To use it you must add the following http module

  <httpModules>
      ...
	  <add name="PerWebRequest" type="Castle.MicroKernel.Lifestyle.PerWebRequestLifestyleManager , Castle.MicroKernel,Version=0.0.1.7, Culture=neutral, PublicKeyToken=407dd0808d44fbdc"/>

  <httpModules>

  The strong name could be omitted if not in the GAC

- Added checks to handle cycles in dependencies graphs and avoid deadly Stack Overflow Exceptions.

- Fixed IOC-24: "Allow user to provide an attribute which will customize how to inspect properties (PropertiesDependenciesModelInspector)"
  Now users can add an 'inspectionBehavior' attribute to the component node that defines
  the inspection strategy. Possible values are
  
  - None: No properties inspection should happen
  - All: All properties will be inspected and collected (on the class and on the superclasses). 
         This is the default behavior
  - DeclaredOnly: Only properties specified on type are checked (superclasses will be ignored) 

- Added overload to ITypeConvertor that accept the current node configuration as well as the type in CanHandleType()

- Change: Better error message when there's an exception 
  setting up properties

- Fixed IOC-25: Overrides on the configuration should be considered a non-optional dependency

  This fix changes a little the MicroKernel behavior. Now if you specify an service override
  through external configuration, it will be considered a _non-optional_ dependency

- Uri usage replaced by CustomUri which, differently than MS' Uri class, has the same
  behavior on net-1.1, net-2.0 and mono

- EventWiring Facility: now when a publisher is requested, the subscribers
  are automatically started. 
  
  The side effects are: 
  
  - when a subscriber is requested it won't be wired automatically. 
  - There no much sense in having a subscriber with a lifestyle other than singleton
  
  I'm still evaluating this idea. Sometimes wiring only when the subscriber is requested
  might make sense, but supporting both approaches is kinda hard.
  

- Applied patch by Alex Henderson <webmaster@bittercoder.com> adding
    IWindsorContainer.RemoveChildContainer(IWindsorContainer childContainer)
    and IKernel.RemoveChildKernel(IKernel kernel)

- Applied fix by Ahmed. Now defines can be used on properties nodes like

  <properties>
   <?if DEBUG?>
    <item>x</item>
   <?end?>
  </properties>

- Now with DictionaryConverter you can specify the keyType and valueType on each entry (kudos to Ahmed)

- xmlinterpreter will throw an exception if a property is not defined but referenced
using #{propertyName} syntax.(Patch from Ahmed)

- XmlProcessor refactored from XmlInterpreter (kudos to Ahmed)
  Now PI are also supported (don't forget to document this on the wiki)

- Support for nested nodes on the properties. (kudos to Ahmed)
  Example:

  <configuration>
    <properties>
       <MyComponentParams>
         <user>Joe</user>
         <pwd>Doe</pwd>
       </MyComponentParams>
     </properties>
     <components id=??Component
       <parameters>#{ MyComponentParams }</parameters>
     </components>
  </configuration>
  
  Will result in 

     <components id=??Component
       <parameters>
         <user>Joe</user>
         <pwd>Doe</pwd>
       </parameters>
     </components>

- Type converter for kernel components. This allows a usage like this:

  <component id="mycomp">
  
    <parameters>
      <servicelist>
        <list type="IMyService, MyAssembly">
          <item>${keytocomponent1}</item>
          <item>${keytocomponent2}</item>
        </list>
      </servicelist>
    </parameters>

- Removed support for MethodMeta on ComponentModel. The design decision here 
  is to make the facilities interested on it to extend MethodMetaInspector
  reading from a specific node.

RC 2
====

- AsyncInitializationContainer introduced. Special container flavor that installs the
  facilities and components using a background thread.

- Support for evaluation of expressions within the xml configuration (kudos to Ahmed)
  The following "statements" are supported:
  
	<define flag="DEBUG" />
	<undef flag="DEBUG"/>
	
	<if defined="DEBUG">
		component/facility nodes
	</if>
	
	<choose>
		<when defined="DEBUG">
			<component id="debug"/>
		</when>
		<when defined="Qa">
			<component id="qa"/>
		</when>
		<when defined="Prod">
			<component id="prod"/>
		</when>
		<otherwise>
			<component id="default"/>
		</otherwise>
	</choose>

- Startable facility: support to specify the attribute startable=true on the configuration

- Better error messages: now the components waiting for dependencies will recursively 
  report what they are waiting for.

- Support for custom lifestyle through configuration (kudos to Bawer Dagdeviren):

  <component id="my.component"
                   type="MyLib.MyComponent, MyLib"
                   lifestyle="custom"
                   customLifestyleType="MyLib.MyCustomLifestyle, MyLib" />

- Added Type converter for enums

- Support to associate configuration nodes to methods. Usage:

	<component>
		<methods>
			<save />
			<save signature="System.String, mscorlib" />
			<save signature="System.String, mscorlib;System.Int32, mscorlib" />
		</methods>
	</component>

  Which is equivalent to

	<component>
		<methods>
			<method name="save" />
			<method name="save" signature="System.String, mscorlib" />
			<method name="save" signature="System.String, mscorlib;System.Int32, mscorlib" />
		</methods>
	</component> 

- IResource introduced (FileResource, AssemblyResource, ConfigResource and UncResource)
  which are accessible through Uris:

  - FileResource:  
    file://pathtofile 
    (For example: file://c:\mydir\file.txt)

  - AssemblyResource:  
    assembly://AssemblyName/ExtendingNamespace/filename 
    (For example: assembly://Castle.Windsor.Tests/Configuration2/include1.xml)

  - ConfigResource:  
    config://sectioname 
    (For example: config://castle will fetch the 
    <configuration><castle> entry in the configuration)

  - UncResource:  
    \\server\file 
    (For example: \\mysharedplace\myconfig.xml)

- IResource, IResourceFactory and IResourceSubSystem introduced

- Ability to use <properties> in configuration files. Usage

	<properties>	
		<prop1>prop1 value</prop1>
		<prop2>prop2 value</prop2>
	</properties>

	<facilities>
	
		<facility id="testidengine" >
			<item>#{prop1}</item>
		</facility>

		<facility id="testidengine2" >
			<item value="#{prop2}"/>
		</facility>
	
	</facilities>


- Ability to use <include> in configuration files. Usage

  Main file:

	<configuration>

		<include uri="file://include1.xml"/>

	</configuration>

  include1.xml:

	<configuration>

		<components>

			<component id="testidcomponent1">
			</component>

			<component id="testidcomponent2">
			</component>

		</components>

	</configuration>
