+2. Analyze and Categorize
+    - Review the title and body of each PR.
+    - Categorize them into: `Added`, `Fixed`, `Changed`, `Removed`.
+    - Identify the contributors for the "Contributors" section.
+3. Create Release Notes File
+    - Determine the correct path: `release-notes/<Major.Minor>/<Version>.md`.
+    - Create the file with the template contents from `release-notes/template/release-notes-template.md`.
+    - Fill in the template, following the instructions present in each section.
+4. Update CHANGELOG.md
+    - Add a new entry at the top of the list (under the Note).
+    - Include all the text from the Added, Fixed, Changed, Removed, etc. sections from the release notes.
+5. Update Release Directory README
+    - Update `release-notes/<Major.Minor>/README.md`.
+    - Add the new release to the table: `| <Date> | <Version> | [Release Notes](<Version>.md) |`.

+## [Preview Release 7.0.0-preview3.25342.7] - 2025-12-08
+
+This update brings the following changes over the previous preview release:
+
+### Added
+
+#### Support for .NET 10
+
+*What Changed:*
+
+- Updated pipelines and test suites to compile the driver using the .NET 10 SDK. Cleaned up unnecessary dependency references. 
+  ([#3686](https://github.com/dotnet/SqlClient/pull/3686))
+
+*Who Benefits:*
+
+- Developers targeting .NET 10.
+
+*Impact:*
+
+- Addressed .NET 10 warnings regarding unused/unnecessary dependencies.
+
+#### Enable SqlClientDiagnosticListener in SqlCommand on .NET Framework
+
+*What Changed:*
+
+- Enabled SqlClientDiagnosticListener functionality on SqlCommand for .NET Framework.
+  ([#3658](https://github.com/dotnet/SqlClient/pull/3658))
+
+*Who Benefits:*
+
+- Developers requiring diagnostic information on .NET Framework.
+
+*Impact:*
+
+- Improved observability and diagnostics for SqlCommand on .NET Framework.
+
+#### Enable User Agent Extension
+
+*What Changed:*
