Release licensekey 3.1.4

Release date: April 14, 2021

We are releasing version 3.1.4 of our auxiliary license libraries (both licensekey and licensekey-volume)  which add support for our brand new iText product - pdfOptimizer

We have introduced a new structure for license files that becomes the main for all iText licenses. You still can use keys in the old format, while all new keys will be issued in the the new format. 

We continue to extend and simplify the volume reporting policy.

Besides that, a bug which caused a key file lock has been fixed.




  • Add PdfOptimizer support to LicenseKey and LicenseKey-Volume modules
  • add the possibility to enforce remote reporting and therefore disallow local reporting


  • SignatureWorker locks the keystore file
