+## Improved translation for parameterized collection
 
-## Feature
+A notoriously difficult problem with relational databases is queries that involve *parameterized collections*:
 
-Something about the feature
+```c#
+int[] ids = [1, 2, 3];
+var blogs = await context.Blogs.Where(b => ids.Contains(b.Id)).ToListAsync();
+```
+
+EF 10.0 introduces a new default translation mode for parameterized collections, where each value in the collection is translated into its own scalar parameter:
+
+```sql
+SELECT [b].[Id], [b].[Name]
+FROM [Blogs] AS [b]
+WHERE [b].[Id] IN (@ids1, @ids2, @ids3)
+```
+
+For more information, [see the EF release notes](https://learn.microsoft.com/ef/core/what-is-new/ef-core-10.0/whatsnew#parameterized-collection-translation).
+
+## Small improvements and bug fixes
+
+- Fix Microsoft.Data.Sqlite behavior around `DateTime`, `DateTimeOffset` and UTC, [see breaking change notes](https://learn.microsoft.com/ef/core/what-is-new/ef-core-10.0/breaking-changes#DateTimeOffset-read) ([#36195](https://github.com/dotnet/efcore/issues/36195)).
+- Fix translation of `DefaultIfEmpty` in various scenarios ([#19095](https://github.com/dotnet/efcore/issues/19095), [#33343](https://github.com/dotnet/efcore/issues/33343), [#36208](https://github.com/dotnet/efcore/issues/36208)).
