Full Changelog: 3.0.0...3.0.1

OpenPDF 3.0.0

OpenPDF 3.0.0

• OpenPDF 3.0.0 uses the new package name org.openpdf. The old com.lowagie is now removed from OpenPDF 3.0.
  This means that source code using OpenPDF must be migrated to use import statements using org.openpdf.* package.

• PDF 2.0 support in OpenPDF – This is a breaking API change:
  All version-related methods now use String instead of char as method parameters. See PdfVersion.java and PdfWriter.java.
  The default version is now PDF 2.0.

  About PDF 2.0:
  PDF 2.0 is the latest official version of the Portable Document Format, standardized as ISO 32000-2:2020.
  It was first published by the International Organization for Standardization (ISO) in July 2017, with a revised edition in December 2020.
  PDF 2.0 introduces improved color management, tagged PDF enhancements, advanced encryption options, and clarifies many ambiguous parts of the PDF 1.x specifications.

  📄 Read the PDF 2.0 (ISO 32000-2:2020) specification

• Added HtmlToPdfBatchUtils and PdfBatchUtils, new batch utilities built on Java 21 virtual threads.
  These APIs improve throughput for HTML→PDF rendering and common PDF tasks such as merge, split, watermark, and encrypt.

The migration to new package name org.openpdf started in OpenPDF 2.4.0, while OpenPDF 3.0 is the first version of OpenPDF which fully uses the new package name.
