+ Fixed TDataStd_NamedData HasSmth() methods to no longer
return true for empty containers.

analysis.

Default and Production. Production activates all available
compiler optimizations.

containers.
+ Modernized NCollection_Vector(NCollection_DynamicArray),
NCollection_Array1, and NCollection_Array2.

small objects).
* Modeling
+ Addressed multiple bug fixes and improvements for various
modeling algorithm methods.
+ Increased memory management performance.
+ Improved overall modeling stability.
+ Resolved canonical geoplane detection problems.
* Visualization

+ Improved SelectMgr_EntityOwner to process the selection
scheme.
+ Modified Image_AlienPixMap::Save() to write into a memory
buffer instead of a file.
+ Reduced sensitivity of lines.
+ Extended AIS_AnimationObject with syntax for defining
rotation around a specific point.
+ Introduced separate gesture mappings for dragging to
AIS_ViewController.
+ Integrated the ability to scale by moving the mouse on
the OY axis.
* Mesh
+ Fixed BRepMesh_IncrementalMesh issue with overflowing
system memory.
+ Unhandled Standard_OutOfRange, BRepMesh_PairOfIndex::Append()
no longer prevents triangulation with large deflection
values.
* Data Exchange
+ Resolved multiple issues regarding DE Wrapper and Step import
and export.
+ Increased STEP parser performance.
+ Introduced thread-safety interface to STEP import and export.
+ Reorganized DE ToolKits according to specific CAD formats.
+ Introduced DE plug-in system to load CAD format providers
during library loading time.
+ Fixed stability issues with XBF and IGES file formats.
+ Addressed general problems with importing VRML V1.
+ Improved processing of STEP-oriented dimensions.
* Draw Test Harness
+ Enabled loading of plugins on Linux OS.
+ Reorganized DRAW DE ToolKits according to specific CAD
formats.

- update to version 7.7.0
* Details on
https://www.opencascade.com/open-cascade-technology-7-7-0-maintenance-release/
* General
+ Improved compatibility with C++17/C++20 compilers
+ Dropped support of pre-C++11 compilers
* Modeling
+ New functionality is implemented, which could verify the
input shape to be placed on a canonical geometry with the
given tolerance.
+ Introduced new tool BRepLib_PointCloudShape generating a
point set for a topological shape.
+ New option in BRepOffsetAPI_MakeOffset - approximation of
input contours by ones consisting of 2D circular arcs and
2D linear segments only, it provides more stable work of
2D offset algorithm.
* Visualization
+ Introduced new interface for creating V3d_View as subviews
of another V3d_View.
+ Added smoothing to row interlaced stereoscopic output.
+ Added word-wrapping option to Font_TextFormatter.
+ Added support of a wide color window buffer format (10bit
per component / 30bit RGB).
+ Added MSAA anti-aliasing support when using WebGL 2.0.
+ Introduced skydome generation feature
3d_View::BackgroundSkydome().
* Mesh
+ BRepMesh works too long and produces many free nodes on a
valid face problems are resolved.
+ Meshing the shape no longer takes too long and visualization
problems are corrected.
+ Wrong shading display of thrusections is fixed.
+ Rendering issue when using deviation coefficient of low
value is resolved.
+ Mesher no longer produce 'bad' result for extruded spline
with given deviation coefficient.
+ Holes in triangulation with large linear deflection are
removed.
+ Broken triangulation on pipe shape is fixed.
* Data Exchange
+ STEP translator now supports tessellated presentations.
+ Transformation tools BRepBuilderAPI_Transform/
BRepBuilderAPI_Copy now handle properly tessellated
presentations.
+ glTF Writer - added support of Draco compression.
+ Introduced DEWrapper - a unified interface to Data
Exchange connectors.
+ Introduced tool XCAFDoc_Editor::RescaleGeometry() for
scaling geometry in XCAF document.
* Configuration
+ SONAME is now configurable in CMake and includes minor
version in addition to major by default
* Documentation
+ Improved samples / tutorials documentation.
+ Introduced new “AIS: Custom Presentation” tutorial.
- Drop upstream patches:
