End of interim releases

This release drops the term "interim release" which distinguished releases made temporarily by the community in the absence of releases made by Internet Archive. The community releases have effectively become the official releases.

In conjunction with this, the version numbers which were paused at 3.4.0 for the interim releases, have now resumed incrementing following the scheme major.minor.patch with the minor release number incremented when features are added or removed.

Java compatibility notice

This will likely be the last release of Heritrix compatible with Java 8. The next release is expected to require Java 17 or later.

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!
