 - Fixed a compilation error when using Hybrid Renderer due to incorrect positioning of macros.
 - Fixed a bug where the `Create Node Menu` lagged on load. Entries are now only generated when property, keyword, or subgraph changes are detected. [1209567](https://issuetracker.unity3d.com/issues/shadergraph-opening-node-search-window-is-unnecessarily-slow).
 - Fixed a bug with the `Transform` node where converting from `Absolute World` space in a sub graph causes invalid subscript errors. [1190813](https://issuetracker.unity3d.com/issues/shadergraph-invalid-subscript-errors-are-thrown-when-connecting-a-subgraph-with-transform-node-with-unlit-master-node)
+- Fixed a bug where depndencies were not getting included when exporting a shadergraph and subgraphs
 - Fixed a bug where adding a " to a property display name would cause shader compilation errors and show all nodes as broken
 - Fixed a bug where the `Position` node would change coordinate spaces from `World` to `Absolute World` when shaders recompile. [1184617](https://issuetracker.unity3d.com/product/unity/issues/guid/1184617/)
 - Fixed a bug where instanced shaders wouldn't compile on PS4.
