+
+## sqlpackage on macOS and Linux 0.0.1 (preview)
+
+release date: May 9, 2018  
+build: 15.0.4057.1
+
+This build contains the cross-platform preview build of sqlpackage that targets .NET Core 2.0, and can run macOS and Linux. 
+
+This is an early preview with following known issues:
+
+- The /p:CommandTimeout parameter is hard coded to 120
+- Build and deployment contributors are not supported
+  - Will be fixed in the move to .NET Core 2.1 where System.ComponentModel.Composition.dll is supported
+  - Need to handle case-sensitive paths
+- SQL CLR UDT types are not supported.
+  - This includes SQL Server Types SqlGeography, SqlGeometry, & SqlHierarchyId
+- Older .dacpac and .bacpac files that use json data serialization are not supported
+- Referenced .dacpacs (e.g. master.dacpac) may not resolve due to issues with case-sensitive file systems.
+  - A workaround is to capitalize the name of the reference file (e.g. MASTER.BACPAC)
