feat: initialize `$mysqllogin` to avoid uninitialized value warnings (major#490). - fix: Restore compatibility with older Perl versions (by @jasongill). - fix: wrap template loading in `get_template_model()` to avoid `uninitialized value` warnings during `require`. - fix: allow `--updateversion` to work on hosts without `mysql`/`mariadb` installed (#36). - fix: skip local SSL certificate warnings if they are in an inaccessible `datadir` (#33). - fix: correct false positives in `check_removed_innodb_variables` by distinguishing real server variables from internal ones (#32). - fix: improve join_buffer_size recommendation formatting in Variables to Adjust (major#881). - fix: suppress MySQL client warning regarding 'DISABLED' boolean value for SSL (major#887). - fix: correctly handle `--defaults-file` and `--defaults-extra-file` without dropping options (major#605). - fix: restore Debian maintenance account automatic login by using idiomatic boolean checks (major#896). - fix: include `tmp_table_size` in per-thread memory calculation for better accuracy (major#864). - fix: add retry mechanism for initial `SELECT VERSION()` query to improve connection resilience (major#782). - fix: prevent `AUTO_INCREMENT` capacity false positives for empty tables (#37). - fix: refactor InnoDB Redo Log Capacity logic to be workload-based and avoid false positives (major#714, major#737, major#777). - fix: add guards against division by zero in calculations for improved stability (major#435). - fix: add truthiness guards to `mysql_innodb` and `mysql_stats` subroutines. - fix: improve `which` logic for better container/minimal environment support. - fix: enhance login failure reporting with detailed output. - ci: enhance Quality Gate to strictly enforce zero-warning policy on GitHub Actions tests. - ci: implement dynamic CI test environment detection by wrapping configuration extraction. - ci: refactor GitHub Actions release and prerelease workflows to support dynamic versions and checksum generation. - ci: migrate maintenance script to GitHub Actions. - refactor: update CLI metadata to use `undef` as default for string/path options. - refactor: replace non-idiomatic `eq '0'`, `ne 0`, etc., with standard truthiness checks. - refactor: replace "master"/"slave" terminology with "source"/"replica" for cultural sensitivity (major#888). - chore(deps): update docker/setup-buildx-action action to v4. - chore(deps): update docker/build-push-action action to v7. - chore(deps): update docker/login-action action to v4. - chore(deps): update softprops/action-gh-release action to v3. ``` ## 📈 Diagnostic Growth Indicators | Metric | Current | Progress | Status | | :--- | :--- | :--- | :--- | | Total Indicators | 12 | 0 | 🛡️ | | Efficiency Checks | 0 | 0 | 🛡️ | | Risk Detections | 2 | 0 | 🛡️ | | Information Points | 10 | 0 | 🛡️ | ## 🛠️ Internal Commit History -
