On January 13, 2025, GitHub unveiled sub-issues, issue types, and advanced search for issues to the delight of users. Sub-issues help organize tasks within a parent-child hierarchy, making tracking progress seamless. Issue types classify and manage tasks across repositories consistently. Advanced search capabilities enable users to find specific issues effortlessly by using complex filters. The updated UI enhances the user experience with features like autocomplete, syntax highlighting, and a faster issue creation process. Notably, CodeQL Action v2 has been retired, and users are encouraged to transition to CodeQL Action v3 for enhanced analysis capabilities. Secret scanning also received updates with new patterns and increased push protection.
