What's new in NHibernate 4.0.4

Aug 17, 2015

Bug:
[NH-3795] - C# compiler "Roslyn" regression

New in NHibernate 4.0.3 (Jan 22, 2015)

New in NHibernate 4.0.2 (Nov 21, 2014)

New in NHibernate 4.0.1 (Sep 22, 2014)

New in NHibernate 4.0.0 CR 1 (Aug 7, 2014)

New in NHibernate 4.0.0 Alpha 2 (Jun 28, 2014)

Fixed mapping by code behaviour when map child subclasses (see NH-3135 and NH-3269)
The constructor of AbstractComponentTuplizer now behaves like AbstractEntityTuplizer in the way that it doesn't create the instantiator any more. Custom component tuplizers that derive
directly from AbstractComponentTuplizer need to add this line of code in their constructor: instantiator = BuildInstantiator(component);
