Closer to Code

Bundler 2.6 introduces a new checksum verification feature to ensure the integrity of Ruby gems throughout the software supply chain. This mechanism protects against tampering by verifying that gems have not been altered since they were first recorded. It offers automated protection during installation and builds trust in the Ruby ecosystem. While it can't prevent the release of new malicious gems, it guards against replacement attacks, ensuring developers use untampered dependencies.
