2021 Se. 2 Patch 1 Hotfix 1 - Re. Notes [2021.03.18.02]


This Hotfix contains some fixes and updates for the 2021 Season 2 Patch 1 Release.


iRACING UI:

General

- The UI should no longer pop-up over a running Sim session with a login prompt.


Paint Shop

- The UI now better automatically tests if a car paint file has been updated, especially in cases where they were not previously (for example when using the "Export" operation from Adobe Photoshop or other image-editing software).



SIMULATION:

Race Control

- Fixed an issue where if a Caution period begins while the leader is in pit lane and has passed the finish line, but everyone else on track is not yet on the same lap, then all drivers on track would get a wave-by to pass the leader.


Dirt Racing

- The dirt tire parameters for a variety of stockcar vehicles have been dramatically updated for more realistic performance, based on feedback from real-world drivers.
- - The following vehicles have these new tires:
- - - ARCA Menards Chevrolet Impala
- - - NASCAR Cup Series Chevrolet Camaro ZL1
- - - NASCAR Cup Series Ford Mustang
- - - NASCAR Cup Series Toyota Camry
- - - NASCAR Gander Outdoors Chevrolet Silverado
- - - NASCAR Gander Outdoors Ford F150
- - - NASCAR Gander Outdoors Toyota Tundra
- - - NASCAR Xfinity Chevrolet Camaro
- - - NASCAR Xfinity Ford Mustang
- - - NASCAR Xfinity Toyota Supra
- - - [Legacy] NASCAR Cup Chevrolet Impala COT - 2009
- - - [Legacy] NASCAR Cup Chevrolet SS - 2013
- - - [Legacy] NASCAR Cup Ford Fusion - 2016
- - - [Legacy] NASCAR Nationwide Chevrolet Impala - 2012
- - - [Legacy] NASCAR Truck Chevrolet Silverado - 2008
- - - [Legacy] NASCAR Xfinity Chevrolet Camaro - 2014
- - - [Legacy] NASCAR Xfinity Ford Mustang - 2016
- - - [Legacy] NASCAR Xfinity Toyota Camry - 2015


New Damage Model

- Fixed the apparent root of the prevalent crash-to-desktop issues plaguing vehicles utilizing the New Damage Model.
- - This issue appears to have been caused by a corruption of the data when opponent wheels were being moderately to severely damaged, or when they were being reattached to a vehicle.

- We are confident in the above fix. However, as a result of this fix, some sweeping updates have been made to our underlying tire attachment system. Because of this, we are taking the extra precaution of keeping the New Damage Model disabled on the following vehicles until we have had some proper time to re-balance their damage states. You can expect the New Damage Model to be re-enabled on these vehicles soon:
- - ARCA Menards Chevrolet Impala
- - NASCAR Chevrolet Monte Carlo - 1987
- - NASCAR Ford Thunderbird - 1987
- - Street Stock


Animation

- Some opponent drivers' heads appeared to be missing. They have been found and successfully re-attached by our expert surgeons. There are only minor complaints of neck pain. Drivers using the following cars were effected:
- - Dallara F3
- - Dallara iR-01
- - Dallara IR18
- - [Legacy] Dallara DW12
- - [Legacy] Indycar Dallara - 2009



CARS:

Lamborghini Huracán GT3 EVO

iRACING UI:

Practice

- Fixed an issue where the drop-down menu for selecting a Setup for an Open Setup Practice was not rendering properly.


3D Model Viewer

- Fixed an issue where if a car already had a custom spec .MIP file actively loaded onto it, it would not update when a new custom spec .MIP file or custom spec .TGA file was copied into the folder.

2021 Season 1 Patch 5 - Release Notes [2021.02.12.01]


This Patch contains some updates and fixes for the 2021 Season 1 Release.



iRACING:

Status Page

- A brand new System Status page has been added for iRacing!
- - https://status.iracing.com

- This web page details the live status of a variety of iRacing's services and servers, allowing you to check-up on our online status at any time.
- - Click on any status report box to get a detailed timeline of that service's performance for the past hour.

- Any current system-wide notifications will be displayed at the top of the page; such as planned maintenance, downtime, or a severe issue we need our Members to know about.

- This web page can be accessed at any time from any device, and is designed to keep you informed.



iRACING UI: (5.06.04)

General

- Fixed a rare issue where the iRacing UI could take the operating system's focus when the connection to the iRacing servers was suddenly severed due to an authentication issue.

- Fixed an issue where the iRacing UI could visually lock-up if it was opened from Membersite when it was already open.


Hosted Racing

- A new Session type, Warm-Up, may now be selected with some event types!
- - A Warm-Up Session precedes a Race Session, and gives drivers, teammates, broadcasters, and race officials some extra free-form time before the big event starts.
- - A Warm-Up Session may be used in Hosted Sessions that contain both a Practice and Qualify Session.
- - When selected, this new Session type includes a time duration slider and an input field for the new Warm-Up period, as well as the ability to set Track State and Time of Day parameters.



MEMBERSITE:

General

- Fixed an issue where opting out of email settings was not being saved correctly.


Hosted Racing

- A new Session type, Warm-Up, may now be selected with some event types!
- - See above for more information.



SIMULATION:

Race Servers

- While a Race Server is creating splits and sessions for an event, no new registrations will be allowed for that event. This process occurs when the window for registering for an event as a participant closes. This is particularly helpful for large-scale special events and team events where dozens of splits and sessions are being created at the same time. Stopping new registrations will reduce the load on the scheduler. Further registration and joining of the sessions, for spotting, spectating, etc., will be allowed again after the sessions have been fully created and launched.
- - This change has no effect on members who register for an event before the splits and sessions are created.



CARS:

Dallara IR18
