- feat: develop LTS API auto-bumping utility with GitHub Actions integration.
- feat: develop version bump dry-run simulation script and post-commit Git hook for automated doc sync.
- feat: re-implement HTML report option (--reportfile) removing CPAN Text::Template dependency (#791).
- feat: make unit-tests target quiet/clean by default in Makefile, and add unit-tests-debug target for verbose debugging.
- fix: resolve false positive AUTO_INCREMENT near max capacity warning on BIGINT UNSIGNED columns with low row count by checking type-specific limits using information_schema (#913).
- fix: refactor version parsing regexes in mysql_version_eq() and helper functions to prevent uninitialized value warnings.
- fix: resolve compile-time and runtime warnings in unit tests, mock override ordering, and definedness checks.
- fix: fix $fh scoping bug in process_sysbench_metrics where file handle was declared inside if(!open) guard and went out of scope before read loop.
- fix: fix $fh scoping bug in historical_comparison (same pattern as process_sysbench_metrics).
- fix: fix hash initialization bug in merge_hash (my %result = {} changed to my %result = ()).
- test: add unit test for type-specific auto_increment capacity warnings.
- test: update issue_37.t to support new information_schema query format.
- test: add unit test for HTML report generation logic.
- test: expand unit tests with parameterized test matrix covering supported/outdated versions across major versions 5, 8, 9, 10, and 11.
- test: add unit_system.t to verify architecture, transport, and formatting helpers, increasing test coverage to 61%.
- test: add unit_coverage_boost.t covering 12 pure utility functions (trim, escape_html, hr_bytes, merge_hash, etc.).
- test: add unit_coverage_boost2.t covering 17 I/O, MariaDB engine, and print wrapper functions (redwrap, file2array, mariadb_tokudb, etc.).
- test: add unit_coverage_boost3.t with deep-mocked tests for 22 diagnostic subroutines (mysql_plugins, mysql_indexes, system_recommendations, check_query_anti_patterns, process_sysbench_metrics, etc.).
- test: improve subroutine coverage from 55% to 92% (154 out of 167 subroutines).
- ci: configure CI workflows to trigger on all branches and execute compliance checks.
- ci: add EOL date check step to CI workflow.
- docs: enhance release-manager workflow with branch lifecycle and checkout hook instructions.
- docs: add Docker installation instructions (docker pull/run) and release location to all README files (EN, FR, IT, RU).
