September 2025 (chef-vault): Implemented Syslog Dependency Management to ensure Ruby 3.4+ compatibility. Moved the syslog gem dependency from Gemfile to the gemspec, introduced an initial Ruby-version condition to support older Rubies during the transition, and then removed the conditional logic to achieve a single, consistent dependency declaration. This reduces install friction for Ruby 3.4+ environments, improves logging reliability, and simplifies ongoing maintenance across the gem. Commits tracked: 7a120635c9afda0eda7f9f5334a5a7ac186cd58a; 17867f540ba20dbf7bea64e8e429ead76d3e2a5a; 39789bdc84fb434f5bc77bb6117ceabd3ccdc682.
