Bottles 67.5 fixes Proton Wayland launches, adds UMU controller and identity bridge support

Bottles, the open-source Windows environment manager for Linux, has released version 67.5 with a focus on gaming compatibility and runner infrastructure improvements. The update fixes several long-standing issues including Proton launches failing when Wayland is enabled for a bottle, UMU controller access problems, and broken game search retries. It also resolves dependency installation when the Z: drive is disabled, font installation failures, and prefix architecture detection during imports.

New capabilities include optional Eagle tracing and native analysis for compatible Soda runners, plus an identity bridge that handles browser return flows and stores account credentials in the system keyring. Other runners maintain their existing analyzer and launch behavior. The release also changes playtime tracking to display hours instead of previous units, and fixes desktop shortcuts, drag-and-drop executable launching, and bottle management UI controls.

Runner infrastructure and compatibility fixes in Bottles 67.5

• Proton/Wayland fix: The bottle-specific Wayland setting now correctly applies to Proton launches, resolving a compatibility path that previously failed.
• UMU integration: Controller access through UMU (Unified Linux Wine Game Launcher) is restored, and failed game searches now retry properly instead of hanging.
• Soda runner extensions: Compatible Soda runners gain optional Eagle tracing and native analysis capabilities, while other runners continue using the existing analyzer without disruption.
• Identity bridge: A new authentication bridge for Soda runners handles browser return redirects and stores account data in the system keyring rather than plaintext.
• Offline resilience: Template downloads and component catalog fallback now function when offline, including recognition of already-installed components.

Why it matters

For Linux gamers using Bottles as an alternative to Steam's Proton or Lutris, this release removes several friction points that forced users to command-line workarounds or runner switches. The UMU and Soda runner improvements strengthen Bottles' position in the broader Wine-based gaming stack, where interoperability between launchers and compatibility tools increasingly determines whether Windows games run without manual configuration. System keyring integration for account storage also raises the security baseline for runner-based authentication flows.
