Bottles, the environment manager for Windows software on Linux, released version 65.2 today. This update introduces support for Steam Runtime 4 (steamrt4) when using Proton 11 and newer. According to contributor @alairon, this feature "enable[s] steamrt4 for Proton 11+," aiming to provide a more consistent and robust execution environment for modern Windows applications and games managed by Bottles. The release also includes a notable fix for program identification. Contributor @mirkobrombin addressed an issue that would "stop advertising programs as Steam apps," correcting instances where non-Steam applications managed by Bottles were incorrectly presented as Steam titles. This update improves the accuracy of application management within the Bottles platform.
