[0.6.0] - 2025-12-20

SSL: Added support for simplified SSL configuration (ssl: required) for Managed/Cloud databases and updated Wizard/Config.
Safety: Added automatic cleanup of housekeeper table during init (targeted) and conflict detection during maintenance.
CLI: Added short flags for all arguments (-vv, -f, -d, -s, -w).
Validation: Enforced strict unit validation for retention periods and strict table existence checks.
Error Handling: Improved error reporting used to identify specific tables causing configuration errors.

CLI: Refactored --init and --fast-init into mutually exclusive standalone commands (Breaking Change).
CLI: Reorganized argument parsing logic for better maintainability.
Safety: Updated initialization warnings to explicitly mention duration ("SEVERAL HOURS") and disk space requirements.
Logic: Refined housekeeper conflict check to only warn about tables actively configured for partitioning.

Wizard: Added interactive configuration wizard (--wizard).
CLI: Added --fast-init flag to skip table scanning during initialization, instead of config option.
Monitoring: Added --stats argument to output JSON statistics (Size, Count, Days Left).
Template: Updated zabbix_mysql_partitioning_template.yaml to use Master/Dependent items for efficient stats collection.

Config: Removed initial_partitioning_start from configuration file (moved to --fast-init).
Template: Replaced legacy check item with comprehensive stats master item.
CLI: Removed legacy --check-days argument (replaced by --stats).

CLI: Added --verbose / -v flag to switch between INFO (default) and DEBUG logging levels.
CLI: Added -r short flag for --dry-run.

Monitoring: Added --discovery argument for Zabbix Low-Level Discovery (LLD) of partitioned tables.
Monitoring: Added --check-days argument to calculate days remaining until partition buffer exhaustion.
CLI: Added --version / -V flag to display script version.
Docker: Added RUN_MODE=discovery and RUN_MODE=check support to entrypoint.py.
Templates: Added Zabbix 7.0 compatible template zabbix_partitioning_template.yaml.

Refactor: Complete rewrite of zabbix_partitioning.py using Class-based structure (ZabbixPartitioner).
Configuration: Extended comments in the configuration file (zabbix_partitioning.conf). The config file is self-explanatory now.
Docker: Introduced Docker container support (Dockerfile, entrypoint.py). The script can be run in a stateless manner using Docker.

Optimization: Added initial_partitioning_start option (db_min vs retention) to speed up initialization on large DBs.
