1.37 Development Update


Since the official release of 1.37 for American Truck Simulator (ATS) and Euro Truck Simulator 2 (ETS2) over a month ago, we have observed an influx of questions and frustration for multiplayer support on the latest version.

Today, we wanted to reach out to the community to express our mutual thoughts around the situation, and to provide an insight into the current progress.


A lot of effort has already gone into porting multiplayer to 1.37, and we would like to assure you that progress is being made daily. You will be happy to know that 1.37 is now in a 'working state', with 90% of the work complete. This is good news, as this means while using the latest version of ETS2 and ATS we can connect to our test servers. However, if there are unexpected bugs presented, this percentage can change at any time.

There has been some speculation of the latest DLC 'FH Tuning Pack' causing a slow-down on the progress. Thankfully, this is not true, as the new DLC can be supported very quickly.

However, what is causing a delay in progress is the newest sound engine (FMOD). This is a new core feature in the game, which has presented new challenges for our developers. Right now they are currently reimplementing the truck sounds, which is consuming 9% of the 10% remaining to complete the port to 1.37. The remaining 1% is for finalising other minor tasks.

In an effort to answer some popular questions, we have listed our answers below. Of course, if there are additional questions you would like to ask, you are welcome to post it on our forum topic. We will monitor the topic over the next few days and answer them as soon as possible.

When is multiplayer support for 1.37 expected to release?

You may have seen it mentioned often that the 1.37 support is 'ready when it's ready', or 'it is coming soon'. We understand this is not helpful information to you, and it can be frustrating not being given any updates about it.

The reason for this is because there are too many possible outcomes to promise a set date. Instead, we can only speculate on a rough time period. However, if things don't go as planned, this can be extended.

Right now only the lead developer 'mwl4' has the knowledge, skills, and tools to prepare the port from 1.36 to 1.37. In addition to him working on the update, he has personal commitments in the real world.

The whole team are supporting him to the best of our abilities, but we are limited to only minor tasks.

Please remember that ETS2 and ATS are single-player games at their core, and having a working multiplayer for so many years is a feat of its own! We know a lot of you are losing patience, but supporting multiplayer takes an unbelievable amount of skill and time.

I already upgraded to 1.37, how can I play on the multiplayer servers?

As multiplayer does not support the 1.37 version yet, you will need to downgrade your game version.

We have provided a guide on how to downgrade your games to 1.36 here: How to downgrade

Why are you still focusing on large official events such as Real Operations V9, instead of working on 1.37?

The TruckersMP Team consists of over 200 members. Each member has an area in the project to focus on. Official events are created by the Event Management and Event Team. They collectively spend thousands of hours to provide the community with fresh and exciting events.

The multiplayer port to 1.37 is an effort the Developers focus on. Presently, only mwl4 and ShawnCZek work on the game client due to their skills and knowledge in that area.

I have seen a lot of client updates recently, are they contributing towards 1.37?

The updates you will have seen recently were primarily bug fixes and features required in general for the multiplayer mod. The target version for these updates was mostly for 1.36, however, some updates were made in preparation for 1.37.

These updates were required and did not affect the 1.37 update progress.

As Summer is approaching, will the Spring weather mod be removed?

The Spring weather mod will be removed on the release of multiplayer support for 1.37.

ProMods 2.46 is ready, will it be supported on 1.37?

Initially, the ProMods servers will be offline for a few days until multiplayer support for 2.46 is ready.

You can expect ProMods to return on version 2.46 shortly after the release of multiplayer on 1.37.

Will the World of Trucks 'Operation Genoa Bridge' event be supported?

As this event is only available in 1.37, it cannot be supported yet. If the event is still active when we support 1.37 then it will be available on multiplayer.

Will the latest DLC 'FH Tuning Pack' be supported?

Yes. We can support the FH Tuning Pack DLC very quickly, so you can expect this to be added in the initial update for 1.37.

This concludes our development update for 1.37.

We would like to say a huge thank you to everyone that continues to support the TruckersMP project. Your patience is greatly appreciated and we understand you are keen for the 1.37 multiplayer support.

We are listening to your questions and concerns about the 1.37 support and hope this information has helped you in some way.
