April’s patch is now available to download and there’s plenty of fixes and improvements for you to review in the patch notes below.

We recently had some exciting STARSEEKER news to share at our [Triple-i Initiative showcase appearance](https://www.youtube.com/watch?v=O_Lyk1etnjI), including an update on the Open Beta starting later this month! That said, it bears repeating that nothing has changed as far as [our commitment](https://blog.astroneer.space/system-era/astroneer-in-2026/) to continue our monthly patches of fixes and improvements for ASTRONEER.

And don’t forget that the [EXO Cares Initiative](https://blog.astroneer.space/p/lte-guide-exo-cares/) is currently running. So, if you want to make the SOL system neat & tidy while earning some sweet rewards, then make sure you check it out.

Something else I wanted to highlight is our [Live Bug Tracker](https://docs.google.com/spreadsheets/d/1zOna9m0PTfJrPnjpR5SwGHOxkSQZIlhcIrdIx3xl0O8/edit?usp=sharing). As mentioned last month, we’re using this to track legacy bugs that have been around since before the release of Megatech. If you run into a bug that’s not already on there then be sure to report them by emailing [support@systemera.net](https://support@Systemera.net).

Note: This update is not backwards compatible, meaning that saves in this version won't run on older versions of the game. If this is relevant to you, you may want to create a backup duplicate of your save file.

##### **FREE STARSEEKER EXPEDITION SUIT**

While we gear up for the launch of STARSEEKER in 2026, we wanted to make sure the Astroneer crew could get in on the fun! **Log in (open up ASTRONEER) at any time for the next few weeks to automatically unlock STARSEEKER's Expedition Suit**.
