Also have changed our example.

Paragraph.cs: Added the Properties LineSpacing, LineSpacingBefore and LineSpacingAfter.

Start to develop chart functionality.

Added AppendEquation method into Paragraph and InsertEquation method into Container/Header/Footer/DocX classes.

Added the method Row.Remove() its easier than calling Table.removeRow(int index)

Fixed a bug with DocX ignoring the CAPS Element.

Added a new unit test to test ReplaceText, based on ReplaceTests.docx
The Test fails.  This functionality worked in the previous release.

Removed the strong name key as per Cathal's suggestion.

Word dose not let you do this and DocX aims to create documents that Word can open.

Big thanks to np83 not only for finding this bug but also posting a fix and unit tests.

When inserted into a Header or Footer Word will automatically display the correct value foreach page.

Word will not automatically update these place holders if inserted inside a document level Paragraph. 
You need to right click and select update field. I therefore suggest that you only use these place holders inside Headers and Footers.

Added
-------

Paragraph.AppendPageNumber(PageNumberFormat)
Paragraph.InsertPageNumber(PageNumberFormat, int index)

Paragraph.AppendPageCount(PageNumberFormat)
Paragraph.InsertPageCount(PageNumberFormat, int index)

Example
-----------
// Create a new document.
using (DocX document = DocX.Create(@"Test.docx"))
{
    // Add Headers to the document.
    document.AddHeaders();

    // Get the default Header.
    Header header = document.Headers.odd;

    // Insert a Paragraph into the Header.
    Paragraph p0 = header.InsertParagraph();

    // Append place holders for PageNumber and PageCount into the Header.
    // Word will replace these with the correct value foreach Page.
    p0.Append("Page (");
    p0.AppendPageNumber(PageNumberFormat.normal);
    p0.Append(" of ");
    p0.AppendPageCount(PageNumberFormat.normal);
    p0.Append(")");

    // Save the document.
    document.Save();
}

Below is a code example which uses the new Protection familiy of functions.

            // Load a document.
            using (DocX document = DocX.Load(@"Test.docx"))
            {
                if (document.isProtected)
                {
                    Console.WriteLine("Document is protected.");
                    Console.WriteLine("\tProtection type is " + document.GetProtectionType().ToString());
                    document.RemoveProtection();
                    Console.WriteLine("\tProtected removed.");

                    // Save the document.
                    document.Save();
                    Console.WriteLine("\tDocument saved as Test.docx");
                }

                else
                {
                    Console.WriteLine("Document is not protected.");
                    document.AddProtection(EditRestrictions.readOnly);
                    Console.WriteLine("\tProtected added.");
                    Console.WriteLine("\tProtection type is " + document.GetProtectionType().ToString());

                    // Save the document.
                    document.Save();
                    Console.WriteLine("\tDocument saved as Test.docx");
                }
            }

            // Wait until a user presses a key before exiting.
            Console.ReadKey();

-----------------
EditRestrictions 

DocX.cs
--------
EditRestrictions GetProtectionType()
AddProtection(EditRestrictions er)

---------
Added property bool isProtected
Added function removeProtection()

Protection is different than Encryption.

This fix checks that an element contains no drawing element and that its text length is zero before removing the element.

This projects contains many of the examples upload on my blog.
Each time docx is released, I will update these examples so as they still work regardless of API changes.
