PdfStreamWriter: Duplicated pages when merging documents with identical page content streams but different per-page Resources.

Workaround: Use the RadFixedDocument.Merge() method instead of the PdfStreamWriter.

The stack shows 1070 repeated frames of:

• StructElementObject.ProcessChildPrimitive(...)
• StructElementObject.CopyPropertiesTo(...)

The StructureTree import is traversing a cyclic StructElement graph (or equivalent re-entrant child chain) without a recursion guard.

During this recursion, indirect object resolution repeatedly re-enters the same compressed object:

• reference.ObjectNumber = 554
• context.CurrentIndirectReference.ObjectNumber = 554
• TryGetIndirectObject(554, ...) == false at re-entry

MethodAccessException is thrown when exporting documents using .NET Standard references in a .NET Framework environment.

Update the "fx:Version" metadata mapping for the XRechnung conformance level.

Glyphs Overlap Due to Incorrect Casting of Glyph Widths from Double to Int.

Corrupted character spacing when exporting PDF/A compliance document with embedded subset fonts.

When the text is long and AllowScroll is false, the text will be visible, but will be misplaced. The issue is caused by the length of the text because the same field with a shorter text that can fit in the widget's rectangle will be displayed correctly.

Endless loop on PDF export when an empty string is assigned to text fields with no source /V and auto-sized default appearance (/DA with 0 Tf).

Workaround: Instead of an empty string (""), set the value to null. Or don't set it at all and leave it unmodified.
