Update 0.20 – The Era of Endurance & Absolute Freedom

🏁 Multi-Category & Endurance Revolution

• Multi-Category Simulation: Simulate multiple vehicle categories simultaneously on track with near-infinite customization.

• Expanded Lineups: You can now change the number of drivers per team (e.g., field 3 or more drivers per car).

• Relay & Stint System: Full integration of live driver swaps during a race to accurately simulate endurance formats.

⚙️ Engineering & Development

• Power Units & Penalties: Complete addition of Engine and Battery systems, including the management of grid penalties for exceeding parts quotas.

• Unique Development Paths: It is now possible to have cars within the same team follow completely different development paths.

• AddedEngine FreezeNew option allowing you to "freeze" engine development.
• AddedSpecial Aero Kits (Ovals)Added a dedicated aero mode for oval circuits. This can be activated globally in the rules or per specific circuit for mixed categories, giving you complete creative freedom.

🏎️ Race Strategy & Physics

• AddedFuel & Refueling (In Testing)Added races with fuel management. You can adjust pit stop times, fuel loads (in liters), and choose the exact performance impact of fuel weight per kg.

• Custom Tire Creation: Build your own tire compounds from scratch (colors, speed, durability). You can even set rules to mandate racing with only a single tire type.

• Customizable Pit Rules: Freely modify pit stop duration parameters, mandatory pit stops, or the obligation to use two different tire compounds.

• Added2D Car BehaviorAdded a parameter to finely tweak how cars behave and handle in the 2D view.
• AddedSimulation Core UpgradeA massive, less visible but highly impactful overhaul of the background simulation system, taking many new factors into account.

🛠️ The Ultimate Editor (Never-Before-Seen Freedom)

• Economic & Technical Control: Modify infrastructure costs, crash test reset values, Understanding reset values, and driver stat progression rates.

• AddedPerformance Estimator ButtonA magic new tool in the editor that calculates and estimates car performances for every track without needing to launch a game session.

• Custom Prize Money: Completely change the ranking rewards and payouts for any category.

• AddedRegulationsAdded parameters to decide the weight and importance of various regulations.

• Track Editor Improvements: More precise tools and enhancements for track creation.

👔 Team Management, Drivers & Sponsors

• AddedSponsor System OverhaulSponsors can now demand specific conditions, impose strict performance objectives, sign multi-year contracts, and you can add custom sponsor images per category. A new dedicated tab makes tracking them easier.

• Driver Generation: Choose the nationalities of generated drivers and tweak the probabilities. You can also set the specific age at which "regens" appear and their retirement age.

• Transfer Market Limits: Impose min/max age limits, level caps, and potential limits for drivers within a specific category.

• AddedEngines & LoyaltyIn the editor, added "Owned Engines" (manufacturer status), engine loyalty mechanics, and team objectives.

• Academies & Manager Rating: Driver academies can now be tied to a configurable country. Additionally, the Manager's rating system is much deeper.

🖥️ Quality of Life, AI & Performance

• AI Behavior: Major improvements to AI decision-making, particularly regarding how they handle car "Understanding".

• Race Control Options: You can modify the severity of penalties for collisions or reliability issues, or completely disable the Safety Car, Red Flag, and VSC.

• UI & Optimization: UI revamped across several menus, massive global performance optimizations, and an enormous amount of bugs squashed.

(Developer Note: I've made so many changes that I honestly can't list them all, and I've definitely forgotten some major features in this list!)
