Changelog

Internal Part Number: New "Internal Part Number" field added to all inventory items in order for companies to add their own part numbers if needed. Visible in the inventory table (between Part Number and Serial Number), the Add/Edit dialog, and the detail info panel (displayed alongside Part Number as PN (IPN)).

Internal Part Number Search: Fully indexed and included in the inventory search bar.

Splash Screen: Branded splash screen shown during startup while critical checks (database connectivity, device authorization) run in the background.

Data Pre-loading: Inventory data is pre-loaded into memory after sync completes, making the Main Inventory window open faster in Master mode.

Sequential Background Pipeline: Startup tasks chain sequentially for optimal resource usage.

Inventory Table Column Order: "Manufacturer" and "Supplier" columns moved further to the end of the table for easier identification of quantities.

Automatic DB Migration: Migration now applies all column additions automatically on startup for both local SQLite (client) and remote PostgreSQL (master). Existing customers are migrated silently on first launch — no manual steps required. Important for future update rollouts.

Startup Freeze on Slow Networks: Device authorization check no longer blocks the UI thread. Moved all network I/O (connectivity check, remote DB queries) to a background thread, preventing the welcome screen from freezing for up to 10 seconds on high-latency connections.

Auth Status Flicker: Welcome window no longer briefly shows "RESTRICTED MODE" before switching to authorized. Auth status is resolved during the splash screen.

Sync Log Reliability: Fixed a database error that could occur when recording synchronization failures. The activity log is now more robust during network interruptions.

Improved High-Volume Syncing: Resolved a system warning that occurred during large data pushes, ensuring smoother background processing when handling thousands of items simultaneously.

Correct Startup Sync Status: The sync status indicator no longer briefly flashes red "Offline" on startup. It now correctly shows the connection status immediately as the application opens.

Faster Application Launch: Eliminated redundant network checks and artificial delays during startup, providing a smoother and faster transition from the splash screen to the welcome window.

Master User Profiles: Added full name, initials, and digital PDF signature support for Master applications.

Pro PDF Infrastructure: Transitioned to a high-performance SQLite-backed drawing index with lightning-fast search.

Integrated Viewing: Embedded PDF viewer for drawings and documentation directly within the app.

UI Modernization: Introduced sidebar-based settings navigation and title-bar version tracking.

Reliability Overhaul: Fixed critical category sync bugs and optimized high-volume batch synchronization.

v0.7.5 - PDF Lookup: Initial implementation of PDF drawing lookup and directory scanning.

v0.7.0 - Kanban Board: Introduced a visual Kanban board for order tracking and status updates.

Dashboards: Full-featured order dashboards for both Client and Master modes.

Reporting: Foundation for automated report generation and standardized styles.

Fleet Management: Added the ROV Fleet Dashboard for real-time asset tracking.

Recycle Bin: Introduced a safety layer with a dedicated recycle bin for deleted components.

Image Processing: Integrated an image cropper for custom part thumbnails.

Theming Engine: Comprehensive theme support for personalized UI aesthetics.

v0.5.0 - Early Dive Log: Initial rollout of the Dive Log module for mission tracking.

Pilot Profiles: Added the ability to manage pilot data and mission assignments.

Dive History: Started tracking dive durations, depths, and mission outcomes.

v0.4.0 - Master/Client Sync: Implementation of the core synchronization protocol.

Connectivity: Handshake logic between local and remote databases.

UI Refinement: Significant polish to the Inventory and Welcome screens.

v0.3.0 - Welcome Screen: Development of the main entry point with functional action buttons.

Navigation: Improved flow between different application modules.

Stability: Core logic fixes for initial UI interactions.

v0.2.0 - Working Prototype: First functional inventory management interface.

Search & Filter: Initial implementation of part searching and category filtering.

Schema 1.0: Solidification of the physical part and inventory models.

Project Birth: Initial application architecture and PyQt framework setup.

Database Engine: Core SQLite engine and initial schema definition.

Project Identity: The official launch of the ROV Companion project.
