+
+### Multiple AddDbContext calls are applied in different order
+
+[Tracking Issue #32518](https://github.com/dotnet/efcore/issues/32518)
+
+#### Old behavior
+
+Previously, when multiple calls to `AddDbContext`, `AddDbContextPool`, `AddDbContextFactory` or `AddPooledDbContextFactor` were made with the same context type but conflicting configuration, the first one won.
+
+#### New behavior
+
+Starting with EF Core 8.0, the configuration from the last call one will take precedence.
+
+#### Why
+
+This was changed to be consistent with the new method `ConfigureDbContext` that can be used to add configuration either before or after the `Add*` methods.
+
+#### Mitigations
+
+Reverse the order of `Add*` calls.

+
+### EntityTypeAttributeConventionBase replaced with TypeAttributeConventionBase
+
+#### New behavior
+
+In EF Core 8.0 `EntityTypeAttributeConventionBase` was renamed to `TypeAttributeConventionBase`.
+
+#### Why
+
+`TypeAttributeConventionBase` represents the functionality better as it now can be used for complex types and entity types.
+
+#### Mitigations
+
+Replace `EntityTypeAttributeConventionBase` usages with `TypeAttributeConventionBase`.
