Version 1.4.2

• Optimized the CSV import parser to support automatic delimiter detection (detecting both semicolons ; and commas ,), robust UTF-8 Byte Order Mark (BOM) signature handling, and smart column mapping based on standard headers such as id_product.
• Streamlined bulk data operations so that CSV data imports no longer require manual product targeting; the module autonomously extracts product identifiers directly from the uploaded spreadsheet, dynamically designating the targeting interface as "Export only".
• Upgraded bulk document processing to support a comprehensive CSV dry-run simulation preview, generating a detailed pre-update comparison table detailing product IDs, names, references, old vs. new pricing structures, price differences, and profit margins.
• Resolved a critical script error within the product autocomplete search field, fixing a JavaScript exception where value.replace is not a function triggered when looking up items inside the product selection tool.
• Enhanced form submission security by refactoring administrative action triggers to explicit HTML type="button" elements, eliminating accidental manual pricing updates caused by hitting the Enter key or invoking incorrect form submissions during CSV tasks.
• Improved user feedback mechanisms with clearer, more descriptive import error notifications detailing precise structural failures, missing file data, or the absence of valid data rows within uploaded documents.
• Applied general stability enhancements to ensure the CSV importing pipeline cleanly exits through the postProcess controller hook without accidentally triggering unrelated standard form actions.

Version 1.4.1

• Decoupled pricing workflows to create fully independent engine settings, ensuring that the Scheduler, Rules, and CSV utilities utilize isolated scopes (via database prefixes sched_, rule_, and csv_) completely separate from the Manual price change configuration.
• Standardized a comprehensive 1:1 product selection component across all module tabs, giving users identical access to advanced autocomplete search, bulk category filters, and entire catalog targeting everywhere.
• Redesigned the module's look and feel with a modernized back-office user interface driven by a clean mpp_admin.css stylesheet, intuitive dashboard panels, descriptive targeting tiles, and user-friendly explanations tailored for non-technical store managers.
• Enhanced catalog visibility by introducing detailed product lists with image thumbnails, accompanied by vital metadata including product name, unique ID, reference code, current price, and a live counter for selected items.
• Upgraded automation infrastructure with a highly secure front controller cron job architecture (accessible via module/masspricepro/cron?token=...) replacing the legacy actionCronJob hook, complete with a security token and configuration guides for cPanel, Plesk, and native Linux command-line interfaces (CLI).
• Added asynchronous AJAX-driven editing for schedules and rules with a visual "Editing..." notification banner, safe cancellation flows, and automatic interface lockouts for active or expired campaigns to prevent accidental data overwrites.
• Improved overview layouts by adding descriptive "Target products" and "Price action" summary columns directly into the saved schedules and pricing rules listings.
• Integrated an interactive modal preview window for both Rules and Scheduler management, allowing administrators to inspect affected catalog items inside an elegant overlay before finalizing data saves.
• Separated functional module settings from the core updateChecker script into distinctive Module settings and Updates tabs, incorporating localStorage persistence to remember the user's active tab preference.
• Guaranteed forward compatibility with full PrestaShop 9 core engine support via a robust prestashop9compatibility.php structural abstraction layer, ensuring precise monetary currency formatting across versions.
• Significantly expanded localized global reach by introducing over 31 comprehensive translation packages covering all newly integrated user interface strings, sections, and contextual tooltips.

Version 1.4.0

• Engineered the innovative MppPricingEngine core pricing architecture to centralize and unify the logic for preview calculations, real-time adjustments, profit margin tracking, and financial safety limits.
• Introduced a highly requested dry-run live preview system via a dedicated "Preview" tab powered by asynchronous AJAX, displaying a detailed comparative table featuring old price, calculated new price, price variance, and projected profit margin.
• Implemented a robust database-backed modification history and instant revert system utilizing comprehensive data snapshots across newly created database tables, enabling one-click rollbacks of any pricing operation.
• Integrated an automated price scheduler tool to manage promotional campaigns efficiently, giving merchants the power to set precise start and end dates with autonomous rollback execution upon expiration.
• Developed advanced dynamic pricing rules that allow store managers to save custom configuration presets, apply smart filters based on profit margin thresholds (above or below a specific percentage), and simulate changes prior to deployment.
• Added protective price floor and ceiling limits to safeguard store revenue, enforcing strict rules for minimum/maximum prices and minimum margin percentages across all automated mass updates.
• Built a flexible CSV import and export utility, allowing merchants to download product pricing sheets, modify catalog values using external spreadsheet software like Microsoft Excel, and seamlessly re-import the updated data into the PrestaShop catalog.
• Introduced dedicated margin-based pricing adjustments, enabling automatic retail price calculation based on target margin percentages or cost-of-goods-sold (COGS) variables.
• Deployed 4 new specialized database relational tables to optimize data integrity and tracking: masspricepro_history, masspricepro_history_item, masspricepro_schedule, and masspricepro_rule.
• Overhauled the administrative back-office navigation layout, introducing distinct, specialized management sections: Manual price change, Price limits, History, Scheduler, Rules, CSV, and List of products.
• Implemented an intelligent automatic database migration routine using the inconsistency() method to flawlessly create required tables when upgrading legacy 1.3.x module installations.
