Release Notes -- Apache PDFBox -- Version 3.0.0-RC1

Introduction
------------

The Apache PDFBox library is an open source Java tool for working with PDF documents.

This is a first release candidate for the upcoming major release 3.0.0 of PDFBox.
This release contains a lot of improvements, fixes and refactorings. The API is 
supposed to be stable, but we can't guarantee that there won't be any last changes
to it before providing the final release candidate.

A migration guide is available at https://pdfbox.apache.org/3.0/migration.html. It is
still a work in progress and we are happy to include any valuable feedback from our 
community. 

For more details on these changes and all the other fixes and improvements
included in this release, please refer to the following issues on the
PDFBox issue tracker at https://issues.apache.org/jira/browse/PDFBOX.
