JHOVE 1.28 Out Now

JHOVE 1.28 is now available for production use. JHOVE is an open-source file format identification, validation and characterisation tool for digital preservation and part of the OPF reference toolset

This release represents a real effort to clear the historic contribution backlog for JHOVE. The remaining pull requests are either documentation contributions or require more analysis. We received a large number of fixes and improvements from contributors around the world. We’d like to say a huge thank you to everyone who volunteered their time and effort to this release. 

Major new features of this release include:

  • Finally, all messages have IDs, and we’ve removed the code that allows the creation of new ones without IDs.
  • JHOVE will no longer report duplicate messages, which should yield shorter reports.
  • Several improvements to the PDF module, many of which address files that caused loop or overflow errors.
  • Fixed a bug that caused an endless loop for some TIFF files and minor TIFF processing improvements.
  • Improvements to NISO metadata handling.
  • Java 17 compatibility.

There are many more fixes. While this release candidate is out, we will make some changes to the project structure and build, but these won’t change the code/functionality. We will also triage the bug list to discover any fixes to old issues that may have been missed.
