Since our v1 release of Caliburn in October, we’ve had a healthy amount of bug fixes and feature improvements.  The community has really gotten involved and contributed in a big way.  The result of this contribution is the forthcoming v1.1.  As of this post, the release candidate is available for download.  It’s a release almost entirely created based on feedback and patches from the community, with very little of my own ideas involved.  Below is a list of fixes/improvements if you care to dig into the gritty details:

• Added pre-initialization hooks to CaliburnApplication via Marco Amendola's patch.
• Redesign of IThreadPool.  AsynchronousAction will now pass itself as state when enqueing the background task.
• Closed ticket #4672 by making PropertyChangedBase.PropertyChanged virtual.
• Applied jagregory's patch to add single key gestures to WPF and Caliburn.
• Applied marcoamendola's patch for enabling property path syntax with Preview and Dependency attributes. So you can now do things like [Dependencies("Model.IsValid")].
• Applied marcoamendola's patch enabling type hinting for polymorphic databinding in Caliburn.Testability.
• Applied etobi's patch to greatly improve Caliburn's parameter parsing in ActionMessages and CommandMessages. See http://caliburn.codeplex.com/WorkItem/View.aspx?WorkItemId=4644 for an explanation.
• Closed ticket #4826. DefaultWindowManager now sets WindowStartupLocation to CenterOwner for UserControls hosted in windows. Title was enhanced to databind to IPresenter.DisplayName if model implements this interface.
• Closed ticket #4833. Fixed an issue with ViewMetadata and invalid Windows in DefaultViewStrategy.
• Fixed a bug with DefaultWindowManager which caused errors when creating main windows from a user control.
• Improved the flexibility of the DefaultViewStrategy. It no longer requires separate namespaces for ViewModels/Views.
• Closed ticket #4865. Fixed a bug in MultiPresenterManager which affects multiple presenter shutdown.
• Applied sedovav's fix to the Spring adapter.
• Enhanced DefaultViewStrategy's exception to report searched for types when view location fails.
• Applied cheesus' recommendations to add unwire capability to IEventHandler.
• Improved PresenterManager and MultiPresenterManager such that all changes to CurrentPresenter go through ChangeCurrentPresenterCore.
• Bug fixes and improvements to DependenciesAttribute, PreviewAttribute, DependencyObserver and PropertyPathMonitory.
• Added strongly-typed property change notification to PropertyChangedBase.
• Fixed a bug in the SimpleContainer related to generic component registration.
• Added ILifecycleNotifier.AttemptingShutdown which gets fired before the CanShutdownCore method on PresenterBase is called.

• Added IWindowManager and DefaultWindowManager for SL3 and SL4.
• Fixed a few bugs in property change testing.
• Fixed a bug in the MEFAdapter.
