+@section upgrade_occt780 Upgrade to OCCT 7.8.0
+
+@subsection upgrade_780_recommendations New Features and Recommendations
+
+The NCollection containers have been modernized to work with move semantics through the new `Move operator` and `Move constructor`. It is recommended to leverage this functionality in the development process.<br />
+Backward compatibility with STL allocators has been implemented to use the OCCT memory manager with STL allocators (NCollection_Allocator, NCollection_OccAllocator).<br />
+Additionally, utilities have been introduced to work with `shared_ptr` and `unique_ptr` using the OCCT memory manager (`Standard_MemoryUtils.hxx`).
+
+@subsection upgrade_780_ncollection_update Change in Default Clear Behavior for Containers
+
+NCollection container's `Clear(const bool theReleaseMemory = true)` have been changed to `Clear(const bool theReleaseMemory = false)`.<br />
+Impacted classes include `IndexedMap`, `IndexedDataMap`, `Map`, `DataMap`, `DynamicArray(Vector)`, `IncAllocator`.<br />
+This means that allocated memory for the container will be reused. In this case, it's necessary to be careful with `IncAllocator::Reset()` to control owners of memory blocks.
+
+@subsection upgrade_780_hash_utils Reworked Hash Mechanism for Hash Map (NCollection's map)
+
+The `HashCode(value, upperBound)` static method has been removed and `IsEqual(value1, value2)` is no longer used in the map.<br />
+NCollection's map now operates on an STL-like hash mechanism: a struct with a public operator `size_t operator()(object&) const` and `bool operator(object&, object&) const`.<br />
+The difference between STL and OCCT is that the hash struct and comparator are combined into a single struct to reduce conflicts on OCCT's user side.<br />
+Hash utils have been implemented to hash objects, returning `uint32_t` and `uint64_t` depending on the template (`Standard_HashUtils.hxx`). Algorithms used are `MurmurHash` and `FNVHash`.<br />
+Benefits:
+* x64 using 8 bytes to store the hash instead of 4 bytes.
+* OCCT classes will now be usable as elements in STL `unordered_map` and `unordered_set`.
+
+The migration problem will occur at compile time. Make sure that `int HashCode` has been changed anywhere to `size operator` and `bool IsEqual` to `bool operator`.
+
+@subsection upgrade_780_removed_files Removed Hash Specialization Classes
+
+The majority of include files containing only specialized hashes have been removed.
+Their functionality has been consolidated into the hashed object include file (in the "std" namespace).<br />
+It is guaranteed that each removed hash class has been transferred to the native hash mechanism of the hashed class.
+
+The migration problem may arise at compile time. Ensure that you remove any files that have been deprecated.
+
+@subsection upgrade_780_tk_rework Reorganized DE TK
+
+DE TK components have been combined or separated based on specific CAD formats to support plug-in ability.
+* Components now have a "TKDE" prefix. The available list includes `TKDESTEP`, `TKDEOBJ`, `TKDEIGES`, `TKDEGLTF`, `TKDEVRML`, `TKDEPLY`, `TKDESTL`.
+* The DE DRAW TK has been updated in a similar way: DRAW components now have a "TKXSDRAW" prefix. The available list includes `TKXSDRAWSTEP`, `TKXSDRAWOBJ`, `TKXSDRAWIGES`, `TKXSDRAWGLTF`, `TKXSDRAWVRML`, `TKXSDRAWPLY`, `TKXSDRAWSTL`.
+
+Migration problems may occur during configuration time or compile time. Ensure that you update your project configuration accordingly.
+
+@subsection upgrade_780_step_thread_safety Implemented STEP Thread-safety Interface
+
+The STEP interface now uses Static_Interface to extract exchange settings.<br />
+A new ability has been implemented to determine parameters in STEP, avoiding Static_Interface.
+* For reading, use an additional argument with STEP's parameters in `ReadFile` or `Perform`.
+* For writing, use an additional argument with STEP's parameters in `Transfer` or `Perform`.
+
+@subsection upgrade_780_new_memory_manager New Memory Management Functionality
+
+`Standard.hxx` has a new method `AllocateOptimal` for allocating without post-processing (cleaning).<br />
+New profiles to allocate memory (defined at configuration time):
+* `Native` - allocates with standard `malloc` and `calloc` functionality, performance depends on the OS.
+* `TBB` - allocates with TBB's `scalable` allocator functionality.
+* `JeMalloc` - allocates with `jemalloc` functions.
+* `Flexible` - old-way allocation which defines allocation method in real-time by environment variables.<br />
+
+The most recommended manager is `JeMalloc`. To use it with a plugin system, like `DRAW`, please ensure that JeMalloc was built with the `--disable-initial-exec-tls` flag. For more details, visit [JeMalloc](http://jemalloc.net/).
+
+@subsection upgrade_780_optimization_profiles New CMake Variable for Optimization Profiles
+
+`BUILD_OPT_PROFILE` is a new variable to define optimization level. Available profiles:
+* `Default` - specializes only in quality-dependent parameters for the compiler.
+* `Production` - specializes in performance and quality-dependent parameters for the compiler and linker.

+Data Exchange Wrapper (DE_Wrapper)  {#occt_user_guides__de_wrapper}
+============================
+
+@tableofcontents
+
+@section occt_de_wrapper_1 Introduction
+
+This guide explains how to use the **Data Exchange Wrapper** (DE Wrapper).
+It provides basic directions on setup, usage and file creation via DE_Wrapper.
+
+The Data Exchange Wrapper (DE Wrapper) module allows reading and writing supported CAD formats to shape objects or special XDE documents, setting up the transfer process for all CAD files.
+
+It is also possible to add support for new CAD formats by prototyping existing tools.
+
+The DE Wrapper component requires @ref occt_user_guides__xde "XDE" toolkit for operation.
+
+This guide mainly explains how to convert CAD files to Open CASCADE Technology (OCCT) shapes and vice versa.
+This guide principally deals with the following OCCT classes:
+  * The Provider class, which loads CAD files and translates their contents to OCCT shapes or XDE documents, or translates OCCT shapes or XDE documents to CAD entities and then writes those entities to a CAD file.
+  * The Configuration class, which contains all information for the transfer process, such as the units, tolerance, and all internal information for the OCC readers or writers.
+  * The wrapper class, which contains all loaded configuration objects with own CAD format, reads or writes CAD files in the format derived from file extension or contents and saves or loads configuration settings for loaded configuration objects.
+
+@section occt_de_wrapper_2 Supported CAD formats
+
+| CAD format | Extensions | RW support | Thread Safety | Presentation | Package |
+| :--------- | :--------- | :--------- | :----------- | :----------- | :------ |
+| STEP | .stp, .step .stepz | RW | No | BRep, Mesh | STEPCAFControl |
+| XCAF | .xbf | RW | Yes | BRep, Mesh | DEXCAFCascade |
+| BREP | .brep | RW | Yes | BRep, Mesh | DEBRepCascade |
+| IGES | .igs, .iges | RW | No | BRep | IGESCAFControl |
+| OBJ | .obj | RW | Yes | Mesh | RWObj |

+| GLTF | .glTF .glb | RW | Yes | Mesh | RWGltf |
+| VRML | .wrl .vrml | RW | Yes | Mesh | Vrml |
+
+**Note** :
+  * The format names in the first column match the FormatName values used for configuration nodes.
+  * The VendorName for all listed CAD formats is "OCC".
+
+@section occt_de_wrapper_3 DE Session Configuration
+
+Any providers can have their own read/write parameters. The transfer process is set up using DE configuration nodes, which hold all relevant parameters. There are two ways to change the parameter values: directly from code or by an external resource file/string.
+The session is a global or static DE_Wrapper object that stores registered DE configuration nodes and wraps DE commands to work with them. It has some configuration parameters of its own and also keeps track of loaded nodes and specilal global parameters.
+
+@subsection occt_de_wrapper_3_1 Getting a DE session. Code sample
+
+Working with a DE session requires a DE_Wrapper object to be loaded or created first.
+
+Getting the global DE_Wrapping object:
+~~~~{.cpp}
+Handle(DE_Wrapper) aSession = DE_Wrapper::GlobalWrapper();
+~~~~
+Creating a local DE_Wrapper:
+~~~~{.cpp}
+Handle(DE_Wrapper) aSession = new DE_Wrapper();
+~~~~
+It is recommended to create a local one-time copy to work with the session, if no global changes are intended.
+~~~~{.cpp}
+Handle(DE_Wrapper) aOneTimeSession = aSession->Copy();
+~~~~
+@subsection occt_de_wrapper_3_2 Configuration resource
+
+Configuration resource is an external file or string of the following format:
+~~~~{.cpp}
+global.priority.STEP :   OCC DTK
+global.general.length.unit :     1
+provider.STEP.OCC.read.precision.val :   0.0001
+~~~~
+
+@subsubsection occt_de_wrapper_3_2_1 Configuration resource: graph of scopes
+   * **global.** is a scope of global parameters
+     *  **priority.** is a scope of priority to use vendors with their providers.
+     *  **general.** is a scope of global configuration parameter values
+     *  <strong>"..."</strong> is an internal configuration with any internal scopes
+     *  <strong>". : "</strong> is a separator of key-value
+     *  __...__ parameter value, can't contain new line symbols.
+   * **provider.** is a scope of configuration providers
+     *  **STEP.** is a scope of CAD format to configure
+     *  **OCC.** is a scope of a vendor or provider
+     *  <strong>"..."</strong> is an internal configuration with any internal scopes
+     *  <strong>". : "</strong> is a separator of key-value
+     *  <strong>"..."</strong> parameter value, can't contain new line symbols.
+
+@subsubsection occt_de_wrapper_3_2_2 Loading configuration resources. Configuring DE Session
+
+The resource should be loaded after the registration of all providers that should be configured. The resource only impacts registered parameters. To configure a new registered provider it is necessary to load the resource again. Parameters not present in the resource will remain unchanged.
+
+There are two ways to check what parameters are available:
+* C++: Open ConfigureNode file and check the InternalParameter field. Each parameter will be described with a comment. To check the global parameters, use the DE_Wrapper class public methods.
+* Resource: Register all available Nodes to the session, then save the configuration and view all existing parameters.
+
+There are two options for loading a resource: recursive and global parameters only. Recursive is the default option to configure all global parameters (units, priority, enable status) and all registered providers. Non-recursive configures only global parameters and ignores all provider settings. This option is the best for updating provider priority.
+
+@subsubsection occt_de_wrapper_3_2_3 Loading configuration resources. Code sample
+
+Configuring using a resource string:
+~~~~{.cpp}
+  Handle(DE_Wrapper) aSession = DE_Wrapper::GlobalWrapper();

+    "global.general.length.unit : 1\n"
+    "provider.STEP.OCC.read.precision.val : 0.\n";
+  Standard_Boolean aIsRecursive = Standard_True;
+  if (!aSession->Load(aString, aIsRecursive))
+  {
+    Message::SendFail() << "Error: configuration is incorrect";
+  }
+~~~~
+Configuring using a resource file:
+~~~~{.cpp}
+  Handle(DE_Wrapper) aSession = DE_Wrapper::GlobalWrapper();

+
+@subsubsection occt_de_wrapper_3_2_5 Saving configuration resources. Dump of configuration DE Session
+
+Saving the configuration of a DE Session involves dumping all parameters of registered providers.
+If a parameter did not change during the session, its value remains as default.
+
+There are two ways to save a resource: recursive and global parameters only. Recursive is the way to dump all registered provider information. Non-recursive dumps only global parameters, for example, save priority of vendors or the length unit.
+
+It is possible to filter what vendors or providers to save by providing the correct name of the vendor or provider.
+
+@subsubsection occt_de_wrapper_3_2_6 Saving configuration resources. Code sample

+
+@subsection occt_de_wrapper_3_3 Registering providers
+
+To transfer a CAD file using DE Wrapper, it is necessary to register a CAD provider.
+The provider contains internal and global parameters that have default values in the creation stage.
+All registered providers are set to the map with information about its vendor and kept as smart handles. Therefore, it is possible to change the values via handle from external code.
+
+@subsubsection occt_de_wrapper_3_3_1 Registering providers. Code sample
+
+It is nesessary to register only one ConfigurationNode for all needed formats.
+~~~~{.cpp}

+@subsubsection occt_de_wrapper_3_3_3 Realtime initialization. Code sample
+
+It is possible to change a paramater from code using a smart pointer.

+  if (!THE_STEP_NODE.IsNull())
+  {
+    return THE_STEP_NODE;
+  }

+}
+
+// Change parameter value
+THE_STEP_NODE->InternalParameters.ReadRelationship = false;
+THE_STEP_NODE->InternalParameters.ReadName = false;
+THE_STEP_NODE->InternalParameters.ReadProps = false;
+~~~~
+
+@subsection occt_de_wrapper_3_4 Priority of Vendors
+
+DE session is able to work with several vendors with the same supported CAD format. To choose the preffered vendor for each format, use a special priority list.
+
+If the high priority vendor's provider is not supported, a transfer operation is needed (write/read), then the next vendor will be chosen.
+
+@subsubsection occt_de_wrapper_3_4_1 Priority of Vendors. Code sample
+
+~~~~{.cpp}
+  Handle(DE_Wrapper) aSession = DE_Wrapper::GlobalWrapper();
+  TCollection_AsciiString aFormat = "STEP";
+  TColStd_ListOfAsciiString aVendors;
+  aVendors.Appends("OCC"); // high priority
+  aVendors.Appends("DTK");
+  // Flag to disable not choosen vendors, in this case configuration is possible
+  // otherwise, lower their priority and continue to check ability to transfer
+  Standard_Boolean aToDisable = Standard_True;
+  aSession->ChangePriority(aFormat, aVendors, aToDisable);

+@section occt_de_wrapper_4 Transfer of CAD files
+
+To transfer from a CAD file to OCC or from OCC to a CAD file, it is necessary to use a configured DE_Wrapper object. It can be local, one-time or global. Global configuration of DE_Wrapper propagates to all nodes via transfer. There are two options for transferring: using OCC shape or XCAF document. It is possible to work only with real path to/from the file. Streaming is not supported (yet).
+
+The format of input/output file is automatically determined by its extension or contents.
