Bottles 64.0 was released today, introducing NTSYNC support to enhance Windows application compatibility and performance on Linux. This new feature, contributed by Tid0lla, is crucial for improving synchronization primitives within the Wine environment used by Bottles. The update also addresses several significant issues, including drastically slow startup times and UI freezes experienced by users with many installed programs or library entries. Additionally, version 64.0 resolves problems with .desktop links for application names containing spaces and ensures correct StartupWMClass handling for executables. Manager startup side effects during command-line interface launches have also been mitigated, alongside fixes for transient document portal rejection.
