Margin Master 2026.914.13400

Fixed a crash that occurred when loading a saved selection containing a single-date filter (Equal, Greater Than, or Less Than). The application was incorrectly expecting a date range for all date filters, causing the strategy step to fail for Berthoud Ace Hardware.

Added a new RockSolid tab in Options that displays the status of the Microsoft.ACE.OLEDB.12.0 driver required for RockSolid imports and provides a one-click Install/Verify button. The startup check now uses a centralized service that properly detects the driver for 64-bit Margin Master.

Introduced a new single-table architecture option for Mi9 stores, consolidating all store data into one Mi9_mainTable instead of separate per-store or per-team tables. This reduces database complexity, improves query performance through better indexing, and simplifies multi-store operations while maintaining full backward compatibility with existing multi-table configurations.
