2020-03-04 Interim Release
This is the fourth dated, periodic release. It includes a number of significant changes, most importantly updating of the Berkeley Database from a very old version 4.1.6 to version 7.5.11. This resolves a long-standing bug when recovering from checkpoints multiple times, but also means that the Heritrix state files from previous versions are not compatible with this version. In other words:
Any crawl state folders from previous versions of Heritrix are not compatible with this version! You can only use this new release with new crawls!
Some basic release notes are available here. You can find more detailed information in the changelog
