Epic Online Services’ SDK 1.18 is live! Here’s what you need to know.
September 16, 2025
The Epic Online Services (EOS) SDK 1.18 is live, introducing a collection of new features and improvements designed to save you time, give you more control, and enhance the player experience.
Highlights include an updated Epic Online Services redistributable installer, a new Localized Presence feature, and Epic Account Services Friends Web APIs. Read below to learn more about what’s new in 1.18.
Included with this SDK is an updated redistributable installer that introduces significant improvements to the player experience and overall performance. The new installer features silent installation and updates without UI, ensuring a seamless and undisrupted player experience. Players will also see an approximate 20% size reduction on disk storage, and overall faster startup once installed.
The redistributable installer is a prerequisite for games which use the EOS Overlay to enable cross-platform social features such as in-game invites and friend interactions, regardless of which PC storefront they use to access the game. It ensures the Overlay is installed and automatically kept up to date.
Presence data can now be localized to match each player’s preferred language. Developers can define templates and translations in the Developer Portal to render the translated strings in the Social Overlay, or use the Presence Interface to retrieve them programmatically. Updates to presence can be made dynamically via the SDK to keep friends up to date on progress, in any supported language. Translate once, deliver everywhere, no additional work required.
New Epic Account Services Friends Web APIs make it easier to integrate social features into your games or services. Developers can retrieve players’ friends and block lists, providing more flexibility to deliver connected experiences across devices and platforms.
In addition to the updates above, SDK 1.18 has some notable improvements and bug fixes across several features. See the Release Notes or the SDK Changelog in the Developer Portal for a full changelist.
