Since Jan 1, I've received 200+ vulnerability reports and reviewed every one. Most looked AI-generated, and some days different people reported the exact same issue. I assigned just four CVEs. Over 98% were AI slop or unverified. This is the daily reality of OSS.

Made another MCP server for Ruby core development.
Ask "Has matz ever been open to type annotations in Ruby's syntax?" and it feeds the agent what matz said on the mailing lists since 2001, with sources, to answer from.

RubyGems and Bundler now pass their full test suites with RUBY_BOX=1. I am working toward Ruby 4.1 so that Ruby::Box is stable enough for real projects.

RubyGems and Bundler 4.0.19 are out. With the cooldown setting enabled, install, update, and lock now end with a summary of the gem versions skipped because they were published too recently. No more guessing what the cooldown held back.
