- Migrate NCollection map/sequence/array size APIs from int to size_t; Size() returns size_t, Length() remains the int accessor; int overloads delegate through NbBucketsFromInt() with a negative-input guard.
- Add NCollection_LinearVector: contiguous flat-buffer dynamic array with Standard::Reallocate-based growth for trivial types and move-construction for non-trivial types.
- Rewrite NCollection_DynamicArray on top of LinearVector<T*>; switch to power-of-two block sizing with precomputed shift/mask.
- Rework NCollection_BaseMap iterator with a forward findFirst() helper (no negative-bucket arithmetic); unify ReSize/BeginResize/EndResize on size_t.
- Enable thread-safe fast path in NCollection_IncAllocator via std::shared_mutex + CAS bump allocation on atomic AvailableSize; exclusive lock is taken only for new-block allocation and list reordering.
- Remove NCollection_BasePointerVector (superseded by NCollection_LinearVector).
- Remove NCollection_BaseMap::Statistics (unused).
- Add <cstddef> include in NCollection_Primes.hxx so size_t resolves on clean builds.
- Document iterator invalidation contract on NCollection_LinearVector.
- Unify BRepGraph programmatic mutation behind EditorView: delete BuilderView (2648+552 lines); EditorView (3186+930 lines) and EditorView_Mut.cxx own both structural creation (Add*/Remove*) and field-level RAII-scoped mutation (Mut*()) with automatic OwnGen and SubtreeGen propagation.
- Add BRepGraph_MeshCache and BRepGraph_MeshView: two-tier mesh storage separating algorithm-derived caches from persistent (definition) triangulations; freshness is keyed on FaceDef.OwnGen; cache writes do not mutate the model.
- Document the MeshCache invalidation contract in BRepGraph_MeshCache.hxx (which mutations bump Face.OwnGen and how markRepModified closes the loop for Surface/Triangulation reps).
- Add BRepGraph_RefsIterator (generic flat ref scan with RefTraits dispatch) and BRepGraph_ReverseIterator (typed parent-traversal wrappers over reverse-index vectors).
- Rework RefId entity model: replace inline refs with typed RefId vectors; add OccurrenceRef and Kind::Occurrence=7; BRepGraphInc_WireExplorer now requires a VertexRefLookup.
- Rename layers for consistency: BRepGraph_ParamLayer to BRepGraph_LayerParam, BRepGraph_RegularityLayer to BRepGraph_LayerRegularity; rename BRepGraphInc_Usage to BRepGraphInc_Instance.
- Replace RootNodeIds() with RootProductIds() returning product roots only.
- Update BRepGraph and BRepGraphInc READMEs; fix stale RootNodeIds reference.
- Sweep Size() to Length() renames across ~200 callers in TKG2d, TKG3d, TKMath, TKMesh, TKBO, TKOffset, TKShHealing, TKTopAlgo, TKBRep, TKService, TKV3d, TKOpenGl, TKMeshVS, TKDE*, TKXCAF, TKXSBase, TKLCAF, TKStd, and Draw harness.
- Add GTest coverage for new containers and the BRepGraph overhaul: NCollection_DynamicArray_Test, NCollection_LinearVector_Test, BRepGraph_Fuzz_Test, BRepGraph_Iterator_Test, BRepGraph_LayerIterator_Test, BRepGraph_MeshCache_Test, BRepGraph_MutGuard_Test, BRepGraph_ReplaceVertex_Test, BRepGraph_ReverseIterator_Test, BRepGraph_ScenarioMatrix_Test, BRepGraph_TypedIdDispatch_Test, BRepGraph_WireExplorer_Test.
- Added 900+ deprecated alias headers in `src/Deprecated/NCollectionAliases/` providing typedef wrappers with deprecation warnings
- Updated build system to install deprecated headers alongside regular headers
- Moved tcl samples to resource folder.
- Clean up cmake from samples related settings.
- Removed CSharp samples from the repository.
- Removed MFC samples from the repository.
- Removed Qt samples from the repository.
- Removed Inspector samples from the repository.
- Removed glwin samples from the repository.
- Removed webgl samples from the repository.
- Removed xaml samples from the repository.
- Removed Java samples from the repository.
Add single-level rules to ignore everything at the repository root while whitelisting
essential config files and directories. Explicitly allow selected data subdirectories
and top-level src modules, and preserve deeper-level ignore rules.
Add GitHub Actions for TInspector build and clang-format check
Reorganize QT search to work with native Linux packages
Reorganize build-and-test workflow to have actions
Move debug and upgrade user guides to corresponding folders on upper level
Related: remove "debug" pattern from .gitignore to avoid ignoring relevant folder in dox
Changed the rules for the types of the arguments for different operations:
1. FUSE: All arguments and tools should have the same dimension;
2. CUT: The MAXIMAL dimension of the ARGUMENTS should be less
or equal to the MINIMAL dimension of the TOOLS;
3. CUT21: The MINIMAL dimension of ARGUMENTS should be grater
or equal to the MAXIMAL dimension of the TOOLS;
4. COMMON: The arguments and tools could have any dimensions.
For the arguments of collection type (WIRE, SHELL, COMPSOLID)
the type will be passed into the result of the operation.
The documentation should be updated according to new behavior.
Documentation has been updated.
Implemented suggestions by MSV and some grammar changes.

Correction of test cases for issue CR26565
A new script adm/upgrade.tcl defines a Tcl procedure occt_upgrade, to be used for upgrading code of OCCT and applications for changes introduced by OCCT 7.0.
Batch script upgrade.bat is provided for convenience.
File upgrade.dat contains data (lists of classes) required for some upgrade steps.
Details on upgrade procedure are put in dox/dev_guides/upgrade/upgrade.md.
OCCT code corrected to improve compatibility with code based on previous versions of OCCT:
- Added conversion operator of handle to bool, for use in conditional expressions.
- Forward declaration of argument class restored in macro DEFINE_STANDARD_HANDLE.
- Includes of used classes added in some headers to avoid problem of missing includes in dependent code
- Type cast operators to base curve and surface added in GC and GCE2d classes to reduce porting issues.
Added test for local reference to handle initialized by temporary handle to derived class.
WOK and CDL User Guides removed.
WOK scripts used in generation of MSVC projects are put to adm/genproj.tcl
Batch script genproj.bat added, replacing 'wgenproj' command of WOK.
WOK tool for configuring custom.bat is also copied; it is called by genproj if custom.bat does not exist
Environment variable SHORTCUT_HEADERS can be defined in custom.bat to have headers put in inc just shortcuts to actual headers, instead of copies.
Corresponding option "copy OCCT short-cut headers instead of original one to inc folder" is added to genconf dialog
All CMake meta-projects for OCCT are put to OCCT code (including fragments previously generated by WOK).
"/bigobj" compiler flag added to TKQADraw because of the size of its object file
[GeomToStep & Graphic3d] private headers are included from current dir of including source file
prefix '3RDPARTY' from variables that trigger use of 3rd-party products removed
help strings associated with CMake variables revised
identification of Tcl8.6 libraries enables
invariable cmake files moved from wok to adm/templates folder
RELWITHDEBINFO build configuration added
BUILD_TYPE variable was renamed in BUILD_CONFIGURATION
copy just TObj/TObj.msg instead of TObj folder
Option /fp:precise for Visual Studio projects set
Update of documentation for building with CMake; three warnings appeared in VS projects built by CMake corrected
OCCT documentation (Overview and User Guides) has been converted from MS Word files to text-based MarkDown format and added to OCCT sources, in the new subfolder 'dox'. The HTML and PDF articles can be generated from the sources using Doxygen and MiKTeX. See the file OCCT_Docs_HowTo.md for details on the new documentation system.
This branch includes:
- new folder structure for Open CASCADE documentation
- sources of almost all OCCT User Guides and Overview
- tcl and bat scripts, which allow to generate HTML and PDF articles
Structures Graphic3d_CView, Graphic3d_CStructure, Graphic3d_CGroup become classes and their definitions moved from InterfaceGraphic to Graphic3d.
Introduced new class OpenGl_Texture as replacement for OpenGl_ResourceTexture class and static functions in OpenGl_TextureBox.
Graphic3d_TextureRoot now no more communicate within Graphic3d_GraphicalDriver.
Instead class returns image through GetImage() method.
OpenGl_AspectFace - avoid possible NULL-dereference
OpenGl_Texture::Init() - check gluBuild2DMipmaps() return value
OpenGl_Texture - check GL_BGRA_EXT for compatibility
OpenGl_Texture - scale NPOT image when required
Added more description to Graphic3d_TextureRoot class
OpenGl_Texture - added missing break statement for ImgBGR32 case
OpenGl_Workspace::setTextureParams() - fixed local variable aFilterMin overrides visibility of early declared variable
OpenGl_Workspace::DisableTexture() - reset texture matrix
FTGL do not reset texture matrix and corrupt text could be rendered if custom texture has not identity texture matrix.
Directories for generated files (projects, Visual Studio artifacts, Emacs backup files, test results) are added to .gitignore
Suppressed generated files.
Allow to use bat, sh, am, m4 and ac files in subdirectories.
