Bottles 66.7 has been released as a maintenance update just three days after version 66.6, addressing a catalog loading error by enabling IPv4 fallback when IPv6 resolution times out. The update also normalizes bottle copy paths to prevent overwriting and ensures the UI refreshes correctly after deletions. Additionally, it fixes a Flatpak sandbox crash related to launching games from external storage by exposing the UMU data directory. This release continues Bottles' rapid development for Linux users running Windows software, with a focus on resolving existing issues rather than introducing new features

Bottles 66.7: IPv4 Fix and Flatpak Sandbox Patch for Linux Gaming

Bottles 66.7 has arrived, shipped just three days after 66.6 as a focused maintenance release from lead developer Mirko Brombin. The update resolves a common catalog loading error by retrying repository requests over IPv4 when IPv6 resolution times out on partially configured networks. Additional fixes normalize bottle copy paths to prevent accidental overwrites, ensure the UI refreshes on the main thread after deletion, and expose the UMU data directory to fix Flatpak sandbox crashes on external storage. The 15-file patch cycle continues Bottles' rapid development cadence for Linux users running Windows software via Wine and Proton.
