- Patch v0.991.2b (Small Patch) and Game News! - 10 September 2026
Hello everyone! A lottt of announcements to make here. Figured I would make them all at once! A new smaller patch of Team Principal is now live, bringing another round of small fixes, UI improvements, and continued polish to the game (as well as some easter eggs). Patch notes will come later & mods/saves do not need changed. Thank you as always to everyone who has been testing, reporting issues, and helping me keep pushing the game forward.

- v0.991.2 Patch Notes (Major Update) - 8 September 2026
Hello everyone, it is late and I am overdue on sleep -- so these may be formatted improperly, I apologize! But here are the patch notes for the new version nonetheless. On another note - I have seen and met so many new faces over the last couple of weeks, and I genuinely never anticipated the amount of growth and support we have seen recently in such an early stage of the game. It has given me SO much more passion and motivation to keep working on this project (and given me more to do ;) ). I have a ton more in the pipeline that I am really excited to share with you all. I also have some other exciting news and follow-up patches on the horizon this week, so stay tuned! v0.99.2 Patch Notes 🆕 ADDITIONS 🏁 Race, Strategy & Sessions • Added the optional Mandatory Tyre Compound Usage regulation, including wet-weather exemptions, strategy tracking, warnings, and results enforcement. • Expand…
- v0.991 Patch 3 - 1 September 2026
v0.991 Patch 3 Hello! This is another patch primarily focused on major optimizations, light additions, and bug fixes. Can't WAIT to start getting through some of these ideas I have seen from you guys into the game, and to continue refinement of the oval series! Some super exciting ones I see in there. Thanks everyone! Additions Added clickable driver, staff, and team hyperlinks across most management screens, with full back-navigation support for convenient browsing. Added more realistic qualifying timing, drivers who cross the line with 0 seconds left will not be able to record a hot lap, including late-release risk, warnings, AI timing improvements, and driver radio reactions. Added relationship and nationality effects to driver negotiations, so drivers with higher team relationships will slightly bias to those teams. Added Cornering Speeds telemetry across sessions and data exports,…

- v0.99.1 "Definitive" is live now! - 28 August 2026
I have added some other small UI improvements not noted in patch notes. Below are some misc. notes about tonights patch. You may need to mess with your graphics settings upon launch. BUG REPORTS This has been a massive push from my end. I have thoroughly tested this build across multiple seasons, but bugs always...find a way. So please, as always, report any 🐛bug-report or 🐛oval-bug-report you encounter, preferably within the discord server. I WILL address game-breaking ones/crashes within 48 hours, and others as soon as I am able to. MODS As a reminder, mods ARE now out-dated. Please be patient as modders update. I have added the recent version for those who wish to continue saves. NOTES I was unfortunately not able to get to the oval save editor in time, but I have completed the oval roster editor. This series is very much in beta still, so please remember that prior to expecting…
- v0.99.1 "Definitive" Patch Notes. (Large Content, UI, and Optimization Update) - 27 August 2026
Hello all! Wanted to drop my patch notes a little early this time. I anticipate this update will be live on steam either tomorrow, or Friday evening! I am working at pace to get everything wrapped up and ready to ship. This game has seen some very strong growth recently, so apologies if I am not keeping up with everything as well as I usually am! I thank you guys for the continued support, and please, as always, do not hesitate to provide suggestions or ask questions. As some of the longer term players know, I am willing and open to almost ANY idea (just takes time to actually implement). This is meant to be one hell of a sandbox, and it wouldnt be complete without all of your ideas! v0.99.1 "Definitive" Patch NotesAdditionsPersonnel and negotiationsReplaced the old Personnel Negotiation Points system with a centralized, dynamic negotiation ledger for Formula and Oval, complete with sta…
- Patch v0.99c #3 (Minor Update) - 10 August 2026
Hello! Yet another small-ish patch of items I wanted to clear, and some highly requested features from players! New Features: - Session Log Exports: For those who wish to analyze laptimes, sectors, wear, etc., I have added an "export" button to results screens that allow you to download CSV files of laptimes, track states, and events for all competitive sessions. - Pre-Qualifying: Pre-qualifying historically was a session teams went through when there were a large amount of cars showing up to races, back in the 80s and 90s. This session will trigger if the grid has over 30 cars, and certain teams will have to fight their way through pre-qualifying to make it to qualifying. These sessions are only active on grids of over 30! Drivers who do not make it through pre-qualifying will show as "DNPQ" on standings screens. Improvements: - Improved blue flag behavior in races, racing behavior, an…
- Patch 0.99c Hotfix - 7 August 2026
Hello my favorite people - another small update/hotfix. This addresses two crashes reported, and some other various things I wanted squared away whilst I had a chance to work on them. - Fixed both the academy UI crash that occurs when you scroll up or down on the bottom right panel, and the lap history crash. - Fixed auto-builder in oval not working properly when queuing parts in the Factory. - Made track rubber make sense. It persists between sessions, goes away in the rain, etc.. Track Rubber builds from Practice -> Q1/Q2/Q3 -> Race, and builds faster in hotter conditions. - Fixed Q3 AI run-spacing, so that they stop attempting to pack race in formula cars in qualifying. AI cars will go out in a much more realistic manner now. Qualifying still has much more variety than before 0.99c.(this is more realistic in my opinion) Thanks!
- v0.99c - Major Update (Oval Series Beta) - 5 August 2026

Some Highlights: Drivers use five 1–20 ratings: short oval, intermediate, superspeedway, road course, and control. Each ent…
- Patch v0.99b (Moderate Update) - 14 July 2026
Hello Team Principals! (is that catchy?) I would like to release my patch notes for the newest build - v0.99b! This patch includes various new features, optimizations, UI overhauls, and lots of bug squashing. I will break out the new features below to look forward to in this update. I hope you all enjoy, and as always, feel free to relay feedback or bugs to me so I can address them. Im going to take a different approach to these patch notes this time around, as my documentation log on bug-fixes was lost, so this will focus on features and improvements in this version. Features ERS Development ERS systems can now either be disabled, spec, or open in regulations. Open regulations are enabled within the default26 roster, and spec in others, and are a new development option for teams looking for extra performance. Teams each individually develop their batteries, and can upgrade recharge, ba…

Good evening! The new version of Team Principal (v0.99..i need to change my numerical digits as we are creeping up to 1.0 hahaha) will be published on steam shortly as the MAIN version! This version is a light-weight update, but packs significant UI changes and deepens a couple areas of the game, as well as bug fixes as always! The existing version will remain playable in steam. Here are my quick spark-notes on the big changes, with specific patch-notes to follow later in. There are a LOT of changes not mentioned here. SIGNIFICANTLY revamped dashboard UI. This is a complete change, and I have had to completely tear down and re-implement this UI. I believe this looks a LOT better and will be the standard of my UI's going forward in future updates.Beginnings of a guided tutorial for new players, with a toggle on in the settings to show a guide. This covers about 15% of the game so far and…

- Patch v0.98.2 (Small Patch) - 18 May 2026
Hello all, small patch will be releasing shortly. v0.98.2. This update consists of further fixes to ensure this build is more stable as I begin to plan my next major steps. The only changes to mods will be a new constants file, so to play on the 2026 mods that are updated, just copy paste vanilla constants.py into the mod file 🙂 Additions Added tyre color in practice, qualy, and race UI's, and a small highlight around your drivers on track FINALLY added an icon to the exe lol Fixes/Improvements Fixed AI spending. They are much more competitive at developing in a realistic manner without going endlessly bankrupt for no reason. Spent a lot of time improving AI spending habits. Much improved from my tests. Fixed aero projects at times getting stuck at 99% Fixed small save/reload chassis and engine weight inconsistencies Moved recon emails into debug emails and not development Thanks every…
- Patch 0.98.1 (small maintenance patch) - 14 May 2026
Hi everyone! Just wanted to share that a small update will be live on steam in a few minutes - 0.98.1. This small patch fixes a couple of bugs that shipped alongside 0.98. This patch also adds a feature I have been working on in the background - a spectator mode for those who just wish to watch the AI over time 🙂 Additions: New spectator mode which allows players to watch the game unfold over the seasons, without having any action items themselves. If you wish to jump in, you may do so through the save editor and convert the game into a normal save at any point. Bug fixes: Fixed the game locking players out from signing drivers due to "hierarchy". Driver hierarchy will automatically adjust dynamically depending on what status you sign a driver for, with a small morale boost or buff if you decide to re-order your driver status (i.e, morale will take a hit if you sign a 1st driver alongs…

These will fluctuate through persistent morale/confidence effects from results, team orders, role status, personality, and team context. * Confidence can slightly improve or reduce driver performance depending on current form. * Morale now affects negotiations, contract renewals, team satisfaction, role satisfac…

This update includes two entirely new editors, a refreshed track editor, some bug fixes, loading improvements, race speed improvements, and an additional vanilla roster to enjoy for the newest version of the game! - This patch includes a completely new roster editor, allowing players to easily edit and monitor rosters.

Hello everyone !Not sure what to call this patch, I am thinking 0.97 or something. No clue 😄 but I am releasing the new 0.97 patch tonight! This update focuses on optimizations, bug fixes, and light expansion of features. This will be one of my last patches where I MAINLY focus on optimization, I will continue to overhaul features in the next updates going forward and more features will be added. This patch makes the game much more bug-free, and I have tested up to season 40 with no issues (kill me). Simulated races are still very slow, for which I apologize. This will be something I focus on fixing. Anywways, see below for patch notes! This update will be live within the next hour or so on steam :D. Some high priorities for the game going forward after this update- Negotiation system overhaul for drivers/personnel- In-game editor- Database editor- Speeding up races and simulated races…
