Today I pushed out the AutoMapper 7.0 release:
This release is mainly bug fixes, but keeping with the last few major releases, has a few breaking API changes. The major breaking API change is breaking out the expression mapping (OData support) so that it can release independently of the normal in-memory AutoMapper mapping. You can find this in the AutoMapper.Extensions.ExpressionMapping package.
I've also updated the AutoMapper.Extensions.Microsoft.DependencyInjection package to this release (4.0.0).
