Please see the release notes for more detail. If you are planning to upgrade from older version of Aspose.Words to the current version, we would strongly suggest you to check the Public API and Backward Incompatible Changes section to know what APIs are changed so far.

Here is a look at just a few of the biggest features and API changes in this month’s release.

• Add support of CssClassNamesPrefix in HtmlSaveOptions

Set Chart Series Color and Individual Series Points

In this version of Aspose.Words, we have added the support to set the color of chart series and individual series points using LINQ Reporting. Please read the following article for more detail.

• Using Charts to Represent Sequential Data

Added Property PdfSaveOptions.EscapeUri

In some cases, you may want to encode the URI e.g. encode “/” character to the “%2F”. Starting from Aspose.Words 18.3, we have added support to escape the URI before writing it into PDF. Please refer to the following article for more detail:

• Escape the URI in Output PDF

/// <summary>
/// A flag specifying whether URI should be escaped before writing.
/// </summary>
/// <remarks>
/// Note that if this option is set to <c>false</c> hyperlinks are written "as is",
/// so valid (escaped) URI should be provided in document's model.
/// <para>The default value is <c>true</c>.</para>
/// </remarks>
public bool EscapeUri
{get;set;}

Added Property HtmlSaveOptions.CssClassNamePrefix

We have added a new feature in this release to add a prefix to all CSS class names when the document is exported to HTML. A new property HtmlSaveOptions.CssClassNamePrefix has been added in Aspose.Words 18.3. Please read the following article for more detail.

• Add Prefix to CSS Class Name

/// <summary>
/// Specifies a prefix which is added to all CSS class names.
/// Default value is an empty string and generated CSS class names have no common prefix.
/// </summary>
/// <remarks>
/// <para>If this value is not empty, all CSS classes generated by Aspose.Words will start with the specified prefix.
/// This might be useful, for example, if you add custom CSS to generated documents and want to prevent class
/// name conflicts.</para>
/// <para>If the value is not <c>null</c> or empty, it must be a valid CSS identifier.</para>
/// </remarks>
/// <exception cref="ArgumentException">The value is not empty and is not a valid CSS identifier.</exception>
public string CssClassNamePrefix
{
    get { return mCssClassNamesPrefix; }
    set
    {
        if (StringUtil.HasChars(value) && !CssEscape.IsValidIdentifier(value))
            throw new ArgumentException("The class name prefix must be a valid CSS identifier.");
        mCssClassNamesPrefix = value;
    }
}
