## Summary

RubyGems 4.0.10 and Bundler 4.0.10 have been released with enhancements and bug fixes. RubyGems improvements include a better gem version sorting algorithm, updated SPDX license list, and fixes for NoMethodError in Gem.try_activate and native extension file registration. Bundler enhancements include performance optimizations for gem version comparison (fast path, happy path checks, cached package version selection), improved error messages for platform mismatches, a new default_cli_command config option, and a bug fix restoring rb_sys dependency for Rust.
