JHOVE 1.24 community release candidate out now!

The first release candidate for JHOVE 1.24 is now available for testing. JHOVE is an open source file format identification, validation and characterisation tool for digital preservation, and part of the OPF reference toolset

This community release incorporates the global contributions made during our development and document hack weeks, held earlier this year, as well as independent contributions. These online events aimed to celebrate and encourage meaningful contributions to open source software. We’d like to say a huge thank you to everyone who volunteered effort to this release and helped improve JHOVE for the benefit of the digital preservation community.

Major new features of this release include:

  • A new EPUB module
  • Translations of JHOVE error messages into German, Portuguese, Dutch, Danish and French
  • Document clean up and improvement across modules
