- A problem with BricsCAD crashing when _CLOSE was used as a command tool is fixed.
- Tool Palette:
- When inserting a Block that has been moved from its original file storage location, the tool now searches for the block file in all folders on the current support path. This was a regression since BricsCAD V20.

Tooltips:
- Tooltips are now displayed for overlapping entities.

- New RibbonTab properties 'IsVisible' and 'IsActive' have been implemented.
- SymbolUtilityServices.RepairSymbolName() and RepairPreExtendedSymbolName() now return the supplied name when it is found to be already valid.
- The Civil.TinSurface class now uses TinSurfaceTriangle, TinSurfaceEdge, and TinSurfacePoint instances to represent every node on the surface network. Properties on each node enable traversing the surface network along every edge.
- The CivilTin namespace has been renamed to just Civil, and the classes within it have been given a good makeover to make them more comfortable to use and more similar to APIs on other platforms. In particular, the TinSurface class includes many new properties (some of which used to be methods) and now exposes direct access to every connected node on the surface network.
- The DatabaseServices.ViewRepBlockreference class has been implemented.
- Accessing the Image (or LargeImage) properties of a RibbonItem when no image source is set no longer throws a NullReference exception.

- We fixed a NullReferenceException thrown whilst using material components with null MaterialMap properties.
- The 'ViewToBeUpdated' and 'ViewWasUpdated' events are now implemented on Bricscad.GraphicsSystem.Manager.

.NET Ribbon:
- The background of custom WPF ribbon panels is now themed to match the host ribbon panel's background colors.

.NET/BRX:
- Introduced new C++/MFC BcUiPanelMFC and managed .NET Windows.Panel classes for implementing custom panels that behave like native panels. These classes are not ARX compatible, but are designed to make it as easy as possible to port existing ARX compatible palettes to work as native panels.
- ActiveX:
- IAcadBlockReference::ConvertToStaticBlock() handles non-dynamic blocks now.

BIM LISP:
- Fixes (bim:create-associativeroom) to properly assign the room.

- Fixed (bim:set-property ...) for Boolean BIM properties.

BLADE:
- Fixes an endless loop case when saving a Lisp file to disk under a different name.

BRX:
- Added 'isFullySupported' function to IfcImportCustomizer object; returns whether the specified IFC class is fully supported in BricsCAD's IFC import complex.
- Setting an empty tooltip from an input point monitor, when the quad is otherwise empty, now hides the entire quad window - as expected.
- The old style AcGsClassFactory returned by AcGsManager::getGSClassFactory() is now associated with the current document, and uses the same graphics kernel as the active viewport of its associated document. In earlier versions, it always used a generic 2D graphics kernel.
- A problem with AcDbSpline constructor has been corrected.
- Undocumented function acedNEntSelPEx() now works properly for selecting entities inside a model space viewport while in paper space.

BRX 3D Constraints:
- Extended the 3D Constraints API with a few additional functions

- BRX AcGiTextEngine:
- Fixes an issue with the tesselation of SHX fonts; the assigned SHX font was ignored and txt.shx was always used.

BRX BIM:
- Some API functions crashed when they encountered invalid data. Now they return an appropriate error.

BRX C++ OPM API:
- Fixes a problem with custom AcDbTable entities not showing proper extension properties.

BRX Civil Alignments:
- Implemented BRX interface classes for Civil alignments.

BRX HLR:
- Fixed HLR processing of overlapping entities : edges occluded by other edges could sometimes get a wrong "hidden/occluded" status, instead of "visible".

BRX IFC Import:
- "beforeCompletion()" reactor event was not called (in rare cases), this has been fixed!

BRX OPM API:
- Enabled PickButton editor for PropertiesPanel grid items of type 'opmTypeAngle' and 'opmTypeDistance', grid items of type 'opmTypeDouble' do not enable the pickbutton.
- BRX PaletteSet:
- The CAdUiPaletteSet::SizeChanged() notification now receives a rectangle that excludes the area occupied by the palette tab control.

BRX Ribbon API:
- Setting split button properties now reliably updates the button display.
- BRX/.NET Civil TinSurface API:
- Fixes a problem with AcDbCivilTinSurface::getConstraints() function, where the array did not contain expected objects. The function signature changed, so client code will need to change for V21.

BRX/.NET:
- AcDbSubDMesh (Mesh in .NET) now sets correct vertex orientation flag when generating graphics.

BRX/.NET:
- The BRX acedTraceBoundary() and .NET Editor.TraceBoundary() API function signatures have been extended to support more than two island detection depths.

BRX/.NET:
- The raw image drawn with Geometry.Image() or AcGiGeometry::image() is now scaled correctly based on the supplied u/v vectors.

BRX/.NET/Lisp:
- To match ARX behavior, there are several important changes in existing APIs. These will break existing code that was written for BRX only: 1.) The BRX acedGrVecs(), Lisp (grvecs), and .NET Editor.DrawVectors() functions now interpret input vectors in DCS coordinates instead of UCS. 2.) The transformation matrix in acedDragGen() callback is now a WCS transformation instead of UCS.

BRX/.NET/Lisp:
- The various APIs for getting the implied selection set, like (ssget "I") in Lisp or Editor.SelectImplied() in .NET, now work as expected when the PICKFIRST system variable is set to zero.

BRX:
- In V20, the kLoadDwgMsg notification was sometimes sent after the editor entered a quiescent state. Now, in V21, it is always sent before entering quiescent state.
- A jig's sampler() loop is now called when the Ctrl key is pressed without moving the mouse.
- ACRX_*_DEFINE_MEMBERS macros have been modified in order to eliminate the need for a global variable.
- AcGsReactor events now send notifications with valid AcGsView arguments.
- CAdUiBaseDialog now uses the AdUi message tooltip mechanism for CAdUiOwnerDrawButton tooltips. After this change, plain MFC controls no longer show automatic tooltips.
- Core entity classes include default dynamic properties which are inherited by custom entity classes. These default dynamic properties are now implemented as per-instance dynamic properties.
- Floating paletteset windows are now moved to the main display when their persistent position is not visible, due to a change in the current display configuration.
- It is now possible to cancel closing the application by calling veto() from within the AcEditorReactor::beginQuit() handler.
- Locking the current document for write, within an input point monitor, no longer causes problems while using the mouse wheel to zoom.
- Raw image drawing function AcGiGeometry::image() has been implemented.
- Several incomplete or unimplemented AcGiContext member functions have been properly implemented.
- The acedTraceBoundary() function now returns 'AcDbPolyline' entities when possible... otherwise 'AcDbRegion' entities.
- The application no longer freezes if a document reactor vetoes document closing during application shutdown. #thankgoodness
- The text window now opens automatically during the LIST command, even if a custom entity overrides AcDbEntity::subList() and does not call the base class.
- LayoutSwitched() reactor event is not sent
