+#### General issues
+
+#### PDFsharp features
+
+**Improved access to CropBox, ArtBox, BleedBox, TrimBox**  
+PdfPage now has new properties that make access to those boxes easier.
+These are `HasBleedBox`, `BleedBoxReadOnly`, and `EffectiveBleedBoxReadOnly`.  
+Same applies to ArtBox, CropBox and TrimBox.
+
+**Loading images: Improved access to buffer of MemoryStream**  
+LoadImage from MemoryStream now works with a buffer that is not publicly visible.  
+For better performance, set 'publiclyVisible' to true when creating the MemoryStream.
+
+#### PDFsharp issues
+
+**Lexer.ScanNumber and CLexer.ScanNumber**  
+Based on a bug that crashes PDFsharp if a number in a PDFfile has to much leading zeros, we revised the code of **Lexer.ScanNumber** and **CLexer.ScanNumber**.
+
+**No more commas allowed in XUnit**  
+An old hack allows **XUnit** to be assigned from a string that uses a comma as decimal separator.
+This was a introduced for languages like German, that use a comma instead of a point as decimal separator.
+Now you get an exception. Applies also to **XUnitPt**.
+
+#### MigraDoc features
+
+**MigraDoc Preview user control restored for GDI build**  
+The MigraDoc Preview user control is again available in the GDI+ build.
+MigraDoc Preview samples for GDI and WPF have been added to the samples repository.
+
+**Color.Parse no longer causes exceptions when invoked with a number value**  
+If Color.Parse is invoked with a number value, as in `var color = Color.Parse("#f00");`,
+it no longer throws a handled exception internally.
