+MDL SDK 2019 (314800.830): 20 Feb 2019
+-----------------------------------------------
+
+ABI compatible with the MDL SDK 2019 (314800.830) binary release
+(see [https://developer.nvidia.com/mdl-sdk](https://developer.nvidia.com/mdl-sdk))
+
+**Added and Changed Features**
+
+- General
+    - This release contains a preview version of the new MDL encapsulated (MDLE) file format. Please note that MDLE files generated with this SDK version will be invalidated with the next update.
+    - A new API component `mi::neuraylib::IMdle_api` has been added, which can be used to create MDLE files.
+    - The function `mi::neuraylib::IMdl_compiler::load_module()` can now load MDLE files. Please note that the option `bool "experimental"` has to be set in the `mi::neuraylib::IMdl_execution_context` in order to enable support for `MDL 1.5`, which is needed for MDLE files.
+    - The functions
+        - `mi::neuraylib::IMaterial_instance::is_default()` and
+        - `mi::neuraylib::IFunction_call::is_default()` have been added.
+    - The standalone tool `mdlm` has been extended with MDLE specific commands.
+    - The class `mi::neuraylib::IBaker` has been extended to support baking of constants of type `mi::IBoolean`.
+
+- MDL SDK examples
+    - A new example `example_mdle` has been added to illustrate the use of MDLE files.
+    - The example `example_df_cuda` has been adapted to allow loading and rendering of MDLE files.
+    - A new example `example_generate_mdl_identifier` that illustrates how to generate a valid mdl identifier, e.g., a module name, has been added.
+    - The example `mdl_browser` has been extended to display MDL keywords in the info tooltip as well as above the description in list view mode.
+
+**Fixed Bugs**
+
+- General
+    - A bug when translating light profile and bsdf measurement constructors from the MDL SDK API representation to the MDL Core representation has been fixed.
+
+- MDL Compiler and Backends
+    - The hash calculation for struct field access DAG calls for the PTX code cache has been fixed.
+    - The handling of array parameters in class compilation has been fixed.
+    - A crash when trying to fold an invalid array constructor has been fixed.
+    - Missing parentheses when printing operators with the same precedence as MDL has been fixed (`"a/(b*c)"` was printed as `"a/b*c"`).
+    - A potential crash when generating code for distribution functions has been fixed.
+    - Wrong error messages `"varying call from uniform function"` have been fixed, which were generated by the MDL compiler under rare circumstances for struct declarations.
+    - Wrong error messages `"function preset's return type must be 'uniform T' not 'T'"` have been fixed, which were generated by the MDL compiler for function variants if the original function always returns a uniform result but its return type was not declared as uniform T.
+    - A discrepancy between code execution on CPU and GPU for constant folding of
+    `tt sqrt(c) (c < 0)` has been fixed. Now `NaN` is computed for both.
+
+
