You may also be interested in the 1.23 release report and the breaking changes:

Nutch requires JDK 17 at build and runtime.
The minimum required Hadoop version is 3.5.0 if Nutch is run on a Hadoop cluster.
NUTCH-1732 introduced a new CrawlDatum status, db_parse_failed. A CrawlDb written with Nutch 1.23 might fail to be read with older Nutch versions, if it contains records with status db_parse_failed. As the name indicates, the status marks documents which failed to parse. It is only set if the property parser.delete.failed.parse is true (default: false). If your workflow requires that Nutch data can be read with Nutch 1.22 (or older), please keep the property set to false.

In the 1.X series, release artifacts are made available as both source and binary and also available within Maven Central.
