Both a feature and bugfix release, Tails 4.2 is here to improve and optimize the automatic upgrade feature to use less memory and allow users to upgrade from any previous version to the latest release and do as many automatic upgrades as possible. Manual upgrades will only be required when upgrading to a major release, such as Tails 5.0. Tails 4.2 also comes with several new command-line tools that are being used by SecureDrop users to analyze the metadata of leaked documents on computers that can’t use the Additional Software feature. These include PDF Redact Tools to redact and strip metadata from text documents, Tesseract OCR for converting images that contain text into text documents, and FFMpeg for recording and converting audio and video.
