Nokogiri is the Ruby XML and HTML parser that still sits inside a lot of web scraping, content cleanup, and ETL jobs. This week was a quiet build maintenance pass, but it is worth a look because parser libraries with native code depend on broad, repeatable CI more than most application gems.

Nokogiri v1.19.4 was published on June 18, 2026, with a compact set of security fixes for Ruby XML and HTML parsing paths. The main change for data engineering teams is not a new parser feature, but safer behavior when malformed objects, schema parsing, XInclude processing, and XPath contexts meet long running extraction jobs.
