================================================================================================
change - Typed factory using DefaultTypedFactoryComponentSelector when resolving component
by name will not fallback to resolving by type if component with that name can not be found
and will throw an exception instead.

id - typedFactoryFallbackToResolveByTypeIfNameNotFound
impact - medium
fixability - easy

description - Original behavior from v2.5 could lead to bugs in cases when named component was
not registered or the name was misspelleed and a wrong component would be picked leading to
potentially severe issues in the application. New version adapts fail-fast approach in those
cases to give dvelopers immediate feedback the configuration is wrong.

fix - Actual fix depends on which part of the behavior you want:
- If you do care about the fallback behavior, that is get the component by name and if
not present fallback to resolve by type, you can specify it explicitly when registering your
factory:
.AsFactory(
new DefaultTypedFactoryComponentSelector(fallbackToResolveByTypeIfNameNotFound: true));
- if you don't care about the fallback and what you really want is a 'GetSomeFoo' method
that resolves by type, either rename the method so that its name doesn't start with 'get'
or disable the "'get' methods resolve by name" behavior explicitly when registering your
factory:
.AsFactory(new DefaultTypedFactoryComponentSelector(getMethodsResolveByName: false))
================================================================================================
change - Referencing interceptors by type will not work if the interceptor has custom name.

impact - medium
fixability - easy

description - We unified how referencing components by type works all across Windsor and that
introduced change for some areas like referencing interceptors. Now referencing component
by type means "component implemented by given type with default name". This is how it worked
for service overrides and is now adapted all across the framework.

fix - Remove Name (id in XML registration) from the referenced components if you're not using it
or reference the component by its name.
================================================================================================
change - .Service method on mixing registration has been removed and replaced with .Component.

impact - low
fixability - easy

description - The method had misleading name and behavior inconsistent with the rest of Windsor.
As such it's been replaced with .Component method which is more explicit about what argument
passed to it means

fix - Replace with .Component method:
Container.Register(Component.For()
.ImplementedBy()
.Proxy.MixIns(m => m.Component()));
Notice the new method is behaving consistently with how referencing interceptors and service
overrides works. So you may need to adjust generic argument to point to other component's
implementation type rather than its exposed service.
================================================================================================
change - Generic overloads of .Insert(this IDictionary dictionary, otherarguments) extension
method have been removed.

impact - low
fixability - easy

description - The overload could cause unexpected behavior when the generic parameter was being
inferred, and as such it is removed to make the type always explicit.

fix - Use overload that specifies type explicitly:
d.Insert(typeof(IFoo), new MyFoo()) instead of d.Insert(new MyFoo()) or new, explicit
d.InsertTyped(new MyFoo())
================================================================================================
change - Method object Generate(IProxyBuilder, ProxyGenerationOptions, IInterceptor[]) on type
IProxyFactoryExtension changed signature.


impact - low
fixability - easy

description - To handle new scenarios two additional arguments were introduced:
ComponentModel model and CreationContext context.

fix - If you were implementing IProxyFactory and calling down to IProxyFactoryExtension pass your
own arguments down to IProxyFactoryExtension. If you're implementing IProxyFactoryExtension
adjust your signature and if that makes sense in your context use the arguments.
================================================================================================
change - ProxyUtil class was split and part moved to Castle.Core.dll and other was renamed

impact - low
fixability - easy

description - ProxyUtil contained logic useful not just in the context of Windsor. As such
it was moved to be part of DynamicProxy and most methods are now part of the other assembly.
The only method specific to Windsor: ObtainProxyOptions was left and is now an extension
method in class ProxyOptionsUtil.

fix - If you were using ObtainProxyOptions use it either as extension method or update its type
name to ProxyOptionsUtil. Remining methods are now part of ProxyUtil class which was moved
to Castle.DynamicProxy namespaces and lives in Castle.Core.dll
================================================================================================
change - CreateLifestyleManager method was moved from handlers to IKernelInternal

impact - low
fixability - easy

description - That behavior belongs in the kernel.

fix - You shouldn't be using this method unless you're implementing custom handlers. If you do
call back to the kernel instead of implementing it in yoru handler.
================================================================================================
change - Removed interface Castle.Core.ILifecycleConcern

impact - low
fixability - easy

description - This change was made because with this base interface it was impossible to
implement Castle.Core.ICommisssionConcern and Castle.Core.IDecommissionConcers in single class
Additionaly ILifecycleConcern had no meaning, only the ICommisssionConcern and
IDecommissionConcers have

fix - If you have code using directly ILifecycleConcern (but what for?) you need to
migrate to either ICommisssionConcern or IDecommissionConcers. For code that use
ICommisssionConcern and IDecommisssionConcern you can recompile it to be extra save, but it
is not required.
================================================================================================
change - Removed overloads of Configure and ConfigureFor<> methods of the fluent registration
API that had ConfigureDelegate parameter

impact - high
fixability - easy

description - This change was made to simplify the API and remove ambiguity in cases where a
private method is used to provide the configuration.

fix - This change breaks scenarios where a property was being used as the last element of the
chain in the nested deledate, like:
Configure(c => c.LifeStyle.Transient)
This code will no longer compile. To fix it switch to the new methods exposing lifestyle:
Configure(c => c.LifestyleTransient()) or simply::
LifestyleTransient()
================================================================================================
change - ITypedFactoryComponentResolver interface was removed and ITypedFactoryComponentSelector
now returns Func from SelectComponent method

impact - low
fixability - easy

description - This change was made to simplify coding of advanced custom selectors which means
now only one type needs to be created instead of two and change is much more localized.

fix - If you were using DefaultTypedFactoryComponentSelector this change does not affect you.
otherwise return delegate pointing to Resolve method of your ITypedFactoryComponentResolver
class or inline it altogether.
================================================================================================
change - Add() methods on PropertySetCollection and ConstructorCandidateCollection are no longer
publicly accessible

impact - low
fixability - easy

description - This change was made to ensure and encapsulate the fact that as constructor or
property dependency is added the dependency is also added to Dependencies collection on
ComponentModel.

fix - Use new AddProperty or AddConstructor methods respectively.
================================================================================================
rename - WithService.DefaultInterface() -> WithService.DefaultInterfaces()
description - changed to plural to emphasize more than one interface may be matched.
================================================================================================
change - ResolveAll methods have now different bahaviour.

impact - high
fixability - medium

description - Previously Windsor when ResolveAll was called would try to resolve all components
with implementation type assignable to the type requirested and silently ignore those it
could not resolve. This behavior was introduced before Windsor had ability to support multi
service components and at the time it was the only way to support certain scenarios.
Currently this behavior is no longer required and is indeed leading to issues when dealing
with code that doesn't strictly follow good OOP principles. Also by silently ignoring
unresolvable components it may mask registration issues, that's why it was changed.

fix - Now ResolveAll() will only resolve components that explicitly expose Foo as their
service. If you were depending on the implicit behavior previously, make sure you add all
types you resolve via this method as service to the desired components.
Also Windsor now will throw exception if any of the components can't be resolved. If you
have a legitimate reason to have unresolvable component use IHandlersFilter to filter that
components out.
================================================================================================
change - The following methods were removed:
IHandler.AddCustomDependencyValue
IHandler.HasCustomParameter
IHandler.RemoveCustomDependencyValue
IHandler.OnHandlerStateChanged event
IKernelInternal.RaiseHandlerRegistered
IKernelInternal.RaiseHandlersChanged
IKernelInternal.RegisterCustomDependencies (all 4 overloads)

impact - low
fixability - easy

description - Those members were remainings from the old era and there's no longer any point in
having them.

fix - Pass the dependencies directly to the ComponentModel using DependsOn method on the fluent
registration API. The OnHandlerStateChanged event would no longer be raised so there was no
point in keeping it around either. Use HandlersChanged event on kernel instead.
================================================================================================
change - IReference.Attach and .Detach method have now ComponentModel as their parameter.

impact - low
fixability - easy

description - To accomodate changes in DependencyModel and ParameterModel it was required to
have access to both of them hence ComponentModel is being passed as a more generic object
exposing access to all required elements.

fix - Pass in full ComponentModel, not just it's .Dependencies property. In the reference
use component's properties to do all you require
================================================================================================
change - IDependencyAwareActivator has new method: bool IsManagedExternally(ComponentModel);

impact - low
fixability - easy

description - To implement feature IOC-277 this new customization point was introduced which
allows custom activators to specify whether the instance they activate shoud be managed
by the container. If true is returned this signifies to the container that the component
should not be tracked by the release policy. The activator should in that case also not
invoke any lifecycle steps. Notice that lifestyle manager can override the choice and that
this method will not be called in all cases.

fix - Implement the method however makes sense to you. By default you should just return false.
================================================================================================
change - IExposeDependencyInfo.ObtainDependencyDetails method signature has changed

impact - low
fixability - easy

description - To move the code for constructing the exception when dependencies are missing
out of handlers and open way for different scenarios a new interface was introduced:
IDependencyInspector and it is now used by IExposeDependencyInfo to provide the same
functionality as before.

fix - Adjust the calls to the new signature. If you have custom handler type take a look at
how built in handlers are now implemented.
================================================================================================
change - type attribute is now required and id is ignored in facility XML configuration

impact - low
fixability - easy

description - Since type is uniquely identifying facilities there was no point in keeping the id
around anymore.

fix - This change can affect you in two ways. If you were using facilities node in the XML and
not specifying the type it is now mandatory. Notice Windsor's ability to apply short type
names works here as well, so often just type name is enough - no need to specify assembly
qualified name. Also the assembly will now be instantiated by the container, so if you were
adding it in code later on, this is no longer required (in fact it will throw an exception
saying the assembly was already added).
The other thing that may affect you is if you were looking up facility config namnually via
IConfigurationStore.GetFacilityConfiguration method. It now expects full name of the type
as the key, so you should be calling it like this:
store.GetFacilityConfiguration(typeof(YourFacility).FullName);
================================================================================================
change - EventWiringFacility, FactorySupportFacility and RemotingFacility are extracted to their
own assemblies

impact - low
fixability - easy

description - These facilities are rarely used and two of them (FactorySupportFacility and
RemotingFacility) are mostly considered legacy. As such there's no point in keeping them
in Windsor's assembly, especially in Silverlight version.

fix - Reference the new assemblies and update your references in XML if you use it.
================================================================================================
change - Component.For(ComponentModel) overload was removed.

impact - low
fixability - medium

description - To simplify internal structure of fluent registration API and bring it more in
line with standard registration the overload was removed.

fix - If you really need this overload you can create custom IRegistration that exposes this
functionality. Or better rethink why you need it in the first place.
================================================================================================
change - Adding more than a single facility of any given type is not legal anymore

impact - none (I hope)
fixability - easy

description - Doing so is a bug. Why would you do it in the first place?

fix - Stop doing it.
================================================================================================
change - RegisterCustomDependencies methods were moved from IKernel to IKernelInternal.

impact - low
fixability - easy

description - Those methods are hardly ever used these days so there was no point in polluting
the public API with them

fix - Are you really using those methods? Perhaps you should be using the fluent API? If not
just cast the kernel to IKernelInternal and you can access them.
================================================================================================
change - IWindsorContainer.AddFacility and IKernel.AddFacility overloads that were taking
Func were removed.

impact - low
fixability - easy

description - Those overloads were only cluttering the API and confusing users. There was no
point in keeping them

fix - You should not have to fix that at all. C# compiler (in version 3 or higher) should be
smart enough to pick the Action overload automatically if you're using lambda
syntax. If you aren't, please do, or adjust the call to match the Action overload
================================================================================================
change - IComponentModelBuilder.BuildModel and ComponentModel constructor take ComponenName now
instead of string for 'name' parameter

impact - low
fixability - easy

description - Most of the time name given to components is automatically generated and user does
not care what it is and never interacts with it. To be able to tell apart cases when user
did set the name manually, and when it was auto-generated a new type ComponenName has been
introduced which in addition to the name value keeps track of whether the name was provided
by user or autogenerated.

fix - Update your calls accordingly, creating the ComponentName and passing right values in.
Also in the fluent API the method NamedAutomatically was introduced for use by facilities
and such to register their own components with some name that the user will not care about.
================================================================================================
change - IConfigurationInterpreter.ProcessResource now takes an additional argument: IKernel

impact - low
fixability - easy

description - To accomodate ability not to specify id when configuring components or facilities
in XML config in conjunction with simple type name support in Windsor (this feature that
lets you specify just simple type name like Foo, instead of assembly qualified name like
Acme.Crm.Foo, Acme.Crm) access to conversion subsystem was required and it made sense to
grab entire kernel as some other things could be taken advantage of.

fix - Pass the kernel in.
================================================================================================
change - Release policies have now slightly different semantics.

impact - medium
fixability - medium

description - To limit unnecessary tracking of components, which unnecessarily consumes memory
and causes contention in multithreaded scenarios the following change was made to release
policy semantics:
- only objects whose decommission is managed by the policy (ie which are released by call to
policy.Release, or indirectly: container.Release) can now be Tracked. This is determined by
the 'RequiresPolicyRelease' flag on Burden. If the flag is not set the policy can throw.

fix - The change is likely to affect code using custom lifetime managers. It is now up to the
manager to decide if it will release the object itself (then it should pass 'true' to
'public Burden CreateBurden(bool trackedExternally)' method on CreationContext). Tracking
happens also for objects that require it ('RequiresDecommission' on burden is 'true').
If lifestyle manager wants to make sure the object will be tracked it can set this flag.
Otherwise it is up to Windsor to decide if it needs to track the object or not.
Another side-effect of the change is that calling 'container.Kernel.ReleasePolicy.HasTrack'
may now return 'false', when it previously would return 'true', if the object does not meet
the criteria mentioned above. If you were using this method, make sure you review your code
that depends on it, and adjust it to the new requirements. The semantics of 'HasTrack' is
'does the release policy track this object', not 'does anything in the container track it'
anymore.
================================================================================================
change - IReleasePolicy interface has a new method: IReleasePolicy CreateSubPolicy(); usage of
sub-policies changes how typed factories handle out-of-band-release of components (see
description)

impact - medium
fixability - easy

description - This was added as an attempt to enable more fine grained lifetime scoping (mostly
for per-typed-factory right now, but in the future also say - per-window in client app).
As a side-effect of that (and change to release policy behavior described above) it is no
longer possible to release objects resolved via typed factories, using container.Release.
As the objects are now tracked only in the scope of the factory they will be released only
if a call to factory releasing method is made, or when the factory itself is released.

fix - Method should return new object that exposes the same behavior as the 'parent' usually it
is just best to return object of the same type (as the built-in release policies do).
================================================================================================
change - IHandler.Release now takes Burden, not object as its parameter. Burden.Release now has
no arguments (used to take IReleasePolicy)

impact - low
fixability - easy

description - The method used to take component instance to release. Now it takes Burden which
has some additional information and behavior. Also to decouple Burden from IReleasePolicy
it now uses callback (via Released event) as notification mechanism.

fix - Adjust calls appropriately
//TODO: expand this with better description once the rest of the changes is in place.
================================================================================================
change - AllComponentsReleasePolicy was removed, ILifestyleManager.Resolve has different
signature now, and additional responsibilities.

impact - medium
fixability - medium

description - Handling of decision regarding tracking is now happening in two steps. First step
happens in the lifestyle manager, which gets to decide if the instance should be tracked
at all (which should be chosen when a new instance is created) and if IReleasePolicy should
own (trigger) the release process.

fix - If you implement custom lifestyle consult the implementation of standard lifestyles for
examples how to handle each aspect of component lifestyle management. Broadly speaking the
behavior should be the following (*do* inherit from AbstractLifestyleManager for your own
convenience):
- if your lifestyle employs caching, it should cache Burdens, not the objects resolved
directly. Look up its cache, and if you find matching burden return object it manages
(accessed via 'Instance' property)
- on cache miss call base.CreateInstance to obtain new instnace from activator. This method
will not return the managed object directly but rather a Burden instance. The 2nd argument
'trackedExternally' should be set to true if the lifestyle manager uses some external mecha-
nism to track end of life for components. If not, (when set to true) releasePolicy will take
the responsibility.
- inspect burden's RequiresDecommission property. If its value is true that means either
the intsance obtained or at least one of its dependencies can not be released out of band
and will require to be released explicitly. If the property is set to true you are required
to track the componetn obtained with releasePolicy provided (you can use base.Track method
to acheave that). If the property is false, release policy will ignore the component when
container's Release method is called, and rely on your out of band handling).
- cache your newly obtained instance if needed.
- return the intance, (burden.Instance)
================================================================================================
rename - CreationContext.Empty -> CreationContext.CreateEmpty()
description - readability change to make it obvious that new instance is created each time.
================================================================================================
change - IServiceProviderEx was removed as base interface for IWindsorContainer and IKernel

impact - low
fixability - easy

description - To make the interface for the container more compact the functionality was
extracted to external class - WindsorServiceProvider.

fix - Use WindsorServiceProvider instead.
================================================================================================
rename - INamingSubSystem.GetHandlers -> INamingSubSystem.GetAllHandlers
description - readability change. No affect on behavior
================================================================================================
change - Removed the following methods:
GraphNode.RemoveDepender,
GraphNode.RemoveDependent,
IKernel.RemoveComponent,
IKernelEvents.ComponentUnregistered,
INamingSubSystem.this[Type service],
INamingSubSystem.GetHandler,
INamingSubSystem.GetService2Handler,
INamingSubSystem.GetKey2Handler,
INamingSubSystem.UnRegister(String key),
INamingSubSystem.UnRegister(Type service)
Also INamingSubSystem.Register now takes only IHandler as its argument

impact - low
fixability - none

description - The methods were implementation of "remove component from the container" feature
which was flawed and problematic, hecen was scraped.

fix - Working around is quite dependant on your specific usage. Try utilizing IHandlerSelectors.
For changed Register method, just update your calling code not to pass the name.
handler.ComponentModel.Name is now used as the key, as it was happening in all places so far
anyway, so this change should have no real impact.
================================================================================================
change - Removed the following types: ContainerAdapter, ContainerWrapper, IContainerAdapter,
IContainerAdapterSite

impact - low
fixability - none

description - These types require ability to remove components from a container. This ability
was removed and since these types are hardly ever used, they were removed as well.

fix - No quick fix is possible. If you are depending on this functionality proaly your best shot
is to replicate it, espeicially catering for the removal of components which is no longer
available in Windsor.
================================================================================================
change - Removed ComponentRegistration.If and ComponentRegistration.Until methods, as well as
Component.ServiceAlreadyRegistered method, and replaced their most common usage with
ComponentRegistration.OnlyNewServices method

impact - medium
fixability - easy/hard

description - To make the API simpler easier to discover as well as to allow changes in internal
architecture, the aforementioned changes were made.

fix - Most of the time the removed methods were used in the following combination:
Component.For().Unless(Component.ServiceAlreadyRegistered)
In this case the fix is simple. Just replace the .Unless(Component.ServiceAlreadyRegistered)
with .OnlyNewServices()
If you were using the method in some other way, the fix may be more complicated and depend
on your particular scenario. In those cases it's best to consult Castle users group for
advice on how to proceed.
================================================================================================
change - Rebuilt how components exposing multiple services are handled internally. This includes
several changes to the API:
ForwardingHandler class and IHandlerFactory.CreateForwarding method were removed.
ComponentModel.Service property was removed replaced with ClassService and InterfaceServices
properties. Also AddService method was added. Constructor's argument for service was changed
to be Type[] instead of single Type.
IHandler.Service property was removed, replaced by Services property.
IComponentModelBuilder.BuildModel method takes now ICollection isntead of single Type
as services.
ComponentRegistration.For(Type serviceType, params Type[] forwaredTypes) method was removed.
ComponentFilter delegate type was removed as no longer needed

impact - low
fixability - easy

description - As part of improvement to internal architecture changed how components exposing
more than one service are handled.

fix - This change should not affect most users, unless extending internals of the container. If
that's the case, adjust your calls to the new signatures, and change code anticipating
ForwardedHandlers to use Services collection from the solve IHnadler for any given component
================================================================================================
change - Proxies no longer implicitly implement all interfaces of component implementation type.

impact - medium
fixability - medium

description - This original behavior was actually a bug and would produce unpredictible behavior
for components exposing several services including their class.

fix - if you were depending on the additional non-service intrfaces being forwarded to the proxy
specify them explicitly as addtional interfaces to proxy:
container.Register(Component.For()
.Named("a"),
Component.For()
.ImplementedBy()
.Interceptors("a")
.Proxy.AdditionalInterfaces(typeof(ICommon2))
.LifeStyle.Transient);
================================================================================================
change - NamingPartsSubSystem, KeySearchNamingSubSystem, ComponentName, BinaryTreeComponentName
and TreeNode types were removed.

impact - medium
fixability - medium

description - As part of internal cleanup these esoteric, alternative implementations of naming
subsystem were removed.

fix - behavior of these implementations of naming subsystem can be easily emulated with default
naming subsystem and custom IHandlerSelectors, which is the recommended way to go.
================================================================================================
change - UseSingleInterfaceProxy option was removed

impact - low
fixability - easy

description - As part of clean up of the obsolete API the option was removed to enable certain
internal changes for the release.

fix - if you were using this option and you have to use it, use a IProxyGenerationHook impl
and choose to only proxy members of that single interface.


================================================================================================
release 2.5.2 ==================================================================================
================================================================================================
change - One of CreationContext constructors has now additional argument; parent CreationContext
Method public IDisposable ParentResolutionContext(...) on CreationContext was removed
Method protected CreationContext CreateCreationContext(...) has now additional argument;
parent CreationContext

impact - low
fixability - medium

description - To fix issue with false positive cycle detection (see issue IOC-238) changes had
to be made to how parent creation context gets propagated in certain situation (when call
to kernel.Resolve/ResolveAll is performed as part of resolution process, for example when
CollectionResolver is being used).

fix - If you override CreateCreationContext method on DefaultKernel pass the additional argument
as new constructor parameter to CreationContext.
If you were using ParentResolutionContext method it should be fairly safe to remove the call
if it was preceded by call to updated CreationContext constructor and the CreationContext is
not used outside of local scope. In other cases it's best to consult Castle users group for
advice on how to proceed.
================================================================================================
change - IReference<> interface has two new methods

impact - low
fixability - easy
revision -

description - To make it possible to statically analyze dynamic dependencies provided by
the IReference interface two new methods were added:
void Attach(DependencyModelCollection dependencies);
void Detach(DependencyModelCollection dependencies);

fix - if you're providing dependencies on a component from the container call Attach so that
reference gets a chance to create and add DependencyModel for that dependency so that
it can be statically analyzed by the container.
================================================================================================
change - Method IDependencyResolver.Initialize change signature

impact - low
fixability - easy
revision -

description - To make it possible to use custom DependencyResolver inheriting from
DefaultDependencyResolver initialization of DefaultDependencyResolver was moved out of its
constructor and to IDependencyResolver.Initialize method which now takes IKernel as its
additional parameter

fix - if you're implementing the interface adjust signature of the overriding method to
public void Initialize(IKernel kernel, DependencyDelegate dependencyDelegate)
The method is called by the kernel at the end of its constructor.
================================================================================================
change - Changed visibility of members on AbstractFacility to protected and implementation of
interface members to explicit.

impact - low
fixability - easy
revision -

description - To make it less confusing to users when fluently configuring facilities (via
AddFacility(f => f.ConfigureSomething()) method) visibility of certain members
of AbstractFacility class was changed. Public properties FacilityConfig and Kernel are now
protected, and all methods from IFacility interface are implemented explicitly. Additionally
protected Dispose method was introduced to allow inheriting classes to still be disposed.

fix - If you were using FacilityConfig and/or Kernel properties outside of inherited classes
refactor your code accordingly not to do so. If you were overriding Dispose method change
its signature from
public override void Dispose() to
protected override void Dispose()
================================================================================================
release 2.5.1 ==================================================================================
================================================================================================
change - ILazyComponentLoader.Load now accepts a third argument for additional arguments.

impact - medium
fixability - easy
revision -

description - To allow maximum flexibility and usage with Resolve, any additional arguments
are now passed to the lazy loader.
================================================================================================
change - LifecycleStepCollection class was removed. Instaed LifecycleConcernsCollection class
was introduced. ILifecycleConcern has now two innerited interfaces for commission and
decommission. LifecycleSteps property of ComponentModel was renamed to Lifecycle.
LifecycleStepType type was removed.

impact - medium
fixability - easy
revision -

description - To improve strongly typed nature and decrease probability of mistake and improve
general usability of the type LifecycleStepCollection was removed. In it place similar type
was introduced - LifecycleConcernsCollection. Instead of using untyped Objects and enums
it works with two new interfaces : ICommissionConcern and IDecommissionConcern.

fix - have your lifecycle steps implement one of the new lifecycle interfaces. Use appropriate
overload of Add/AddFirst to add them.
================================================================================================
change - Typed Factories will not implicitly pick default ITypedFactoryComponentSelector
registered in the container anymore

impact - low
fixability - easy
revision -

description - In version 2.1 where ITypedFactoryComponentSelectors were introduced, when you had
a selector registered in the container that selector would be implicitly picked for every
factory you had. Since the behavior of a selector tends to be fine grained and targetet for
a specific factories, this behavior was removed. You have to explicitly associate the selector
with a factory (using .AsFactory(f => f.SelectUsing("MySelector")); or via xml configuration)
to override selection behavior.

fix - using either fluent API .AsFactory(f => f.SelectUsing("MySelector")), or XML configuration
selector="${MySelector}" specify the selector explicitly for each of your factories.
================================================================================================
change - ServiceSelector delegate (used in WithService.Select calls) changed signature

impact - low
fixability - easy
revision -

description - To fix a bug which would occur if type implemented multiple closed version of base
open generic interface the signature of the delegate was changed from
public delegate IEnumerable ServiceSelector(Type type, Type baseType);
to
public delegate IEnumerable ServiceSelector(Type type, Type[] baseTypes);
so that multiple base types are possible (they would be closed versions of the same open
generic interface)

fix - depending on the scenario. You would either ignore it, or wrap your current method's body
in foreach(var baseType in baseTypes)
================================================================================================
change - moved IWindsorInstaller to Castle.MicroKernel.Registration namespace

impact - very low
fixability - easy
revision -

description -In order to improve developer experience when writing installers the interface
was moved so that Component and AllTypes entry types for registration are already in scope.

fix - add using Castle.MicroKernel.Registration directive.
================================================================================================
change - Added two new overloads to ITypeConverter.PerformConversion

impact - very low
fixability - easy
revision -

description - To reduce casting in the most common scenario where converted value is casted to
the type it's been converted to, ITypeConverter.PerformConversion has now generic overloads
for handling this case.

fix - If you're implementing ITypeConverter via AbstractTypeConverter you don't have to do
anything as the base class will handle the conversion for you. Otherwise implement it like
in AbstractTypeConverter.

================================================================================================
change - AddCustomComponent method were moved from IKernel to IKernelInternal interface

impact - very low
fixability - easy
revision -

description - This method constitute internally used contract of kernel and is not intended
for external usage. As such it was moved to internal interface to declutter public
interface of IKernel.

fix - You should not have been using this method so it should not affect you in any way. If
you did, cast the IKernel to IKernelInternal to invoke the method.

================================================================================================
change - IModelInterceptorsSelector.SelectInterceptors method changed its signature and how it
is used.

impact - medium
fixability - medium
revision -

description - To accomodate additional scenarios that were impossible (or hard to achieve
with previous design the method now has additional parameter, an array of references to
interceptors, which contains either default interceptors for the component, or interceptors
selected by previous interceptors in line). Also, Windsor will now never call
IModelInterceptorsSelector.SelectInterceptors without calling
IModelInterceptorsSelector.HasInterceptors before it, or when the latter returns false.

fix - When adjusting your implementation remember that model's interceptors are the default value
passed as methods second parameter, so you don't need to merge them again manually (otherwise
they'll be invoked twice).

================================================================================================
change - CreateComponentActivator, RaiseHandlerRegistered, RaiseHandlersChanged and
RegisterHandlerForwarding methods were moved from IKernel to IKernelInternal interface

impact - very low
fixability - easy
revision -

description - These methods constitute internally used contract of kernel and are not intended
for external usage. As such they were moved to internal interface to declutter public
interface of IKernel.

fix - You should not have been using these methods so it should not affect you in any way. If
you did, cast the IKernel to IKernelInternal to invoke the methods.

================================================================================================
change - IProxyHook interface was removed

impact - very low
fixability - easy
revision -

description - Since MicroKernel was merged with Windsor and now depends on DynamicProxy directly
there's no need to provide additional abstraction on top of IProxyGenerationHook.

fix - Make types that were implementing IProxyHook to implement IProxyGenerationHook. Change all
usages of IProxyHook to IProxyGenerationHook.

================================================================================================
change - AddInstallerConfiguration and GetComponents methods were added to IConfigurationStore.

impact - very low
fixability - easy
revision - 3bf716cc6fc218601dab92a6dd75fe269bcb63d0

description - To enable installers to be exposed via configuration the interface has been
extended by addition of the two methods.

fix - Implement the methods accordingly to your situation.

================================================================================================
change - Multiple types were moved between namespaces

impact - low
fixability - trivial
revision - 3bf716cc6fc218601dab92a6dd75fe269bcb63d0

description - To improve the internal structure several types were moved to other namespaces.

fix - When compilation error occurs adjust namespace imports as suggested by Visual Studio

================================================================================================
change - Assembly Castle.MicroKernel.dll was merged into Castle.Windsor.dll

impact - high
fixability - easy
revision - 730b202b0ed23a6b42258a6ffd6a3e63f89501fc

description - Since vast majority of users used Windsor, as opposed to bare MicroKernel it was
decided it didn't make sense to maintain two containers. As result of that their assemblies
were merged, as first step of integration between Windsor and MicroKernel.

fix - In your projects remove reference to Castle.MicroKernel.dll. If you weren't using Windsor
add reference to Castle.Windsor.dll
In all places where your were referencing types from Castle.MicroKernel.dll via string
(like xml configuration when registering facilities, or section on your
web.config) update references from Castle.MicroKernel to Castle.Windsor.

================================================================================================
change - ComponentRegistration.Startable public method has been removed.
ComponentRegistration.StartUsingMethod public method was moved to extension method.
ComponentRegistration.StopUsingMethod public method was moved to extension method.

impact - low
fixability - trivial
revision - 6710

description - StartUsingMethod/StopUsingMethod belong to StartableFacility and do not make sense
as part of generic API. Startable method was superfluous.

fix - Remove calls to Startable(). Import namespace Castle.Facilities.Startable to use
StartUsingMethod and StopUsingMethod as extension methods.

================================================================================================
change - DefaultProxyFactory.CreateProxyGenerationOptionsFrom protected method and
DefaultProxyFactory.CustomizeProxy protected virtual method have changed signature

impact - very low
fixability - easy
revision - 6691

description - the methods now also takes IKernel and CreationContext, to be used by IReferences
to do resolution of components they reference

fix - pass required parameters to the methods.

================================================================================================
change - ProxyOption's properties changed types:
Selector, from IInterceptorSelector to IReference
Hook from IProxyHook to IReference
MixIns from object[] to IEnumerable>

impact - very low
fixability - easy
revision - 6691

description - the properties now use IReferences instead of live objects to allow for
resolution of their values from the container, as required in case of usage from xml.

fix - wherever used, adjust types appropriately. To obtain actual objects, use Resolve method.
