History of PDFsharp

Here are the news and improvements of PDFsharp.

What’s new in version 6.1

See general history for changes that affect PDFsharp and MigraDoc.

Font handling was improved and this should lead to smaller PDF files in some cases.

What’s new in version 6.0

Core builds now can be used everywhere

With version 1.51, the Core builds were still limited to Windows. Beginning with version 6.0, the Core builds can also be used under Linux and other platforms.

Security updated

Earlier PDFsharp versions support only encryption introduced with the third PDF specification (PDF ???) or earlier. PDFsharp now reads and writes PDF files with AES 256 that comes with PDF 1.7 and crypt filters that came with PDF 2.0.

SharpZipLib removed

Earlier PDFsharp versions used SharpZipLib for compressed content streams. This library was replaced by equivalent functionality that comes today with .NET. This should make compression and decompression much faster.
