What's new (v1.17)
Fixed: signing a PDF that already carries a signature from Adobe Acrobat, Microsoft Word or an e-signature service (compressed PDF structure) failed with “This signed PDF cannot be updated safely.” Such documents can now be counter-signed.
Fixed: an intermittent “The signature page reference could not be resolved.” error when signing larger documents.
