Vamp Plugin SDK

Version 2.9, 2019-10-23 (maintenance release)

  * Fix non-thread-safe behaviour in PluginAdapter. Plugins built

    using the adapter classes in version 2.8 or earlier cannot safely

    be used simultaneously across threads with other instances of

    themselves or of other plugins in the same library (i.e. shared

    object). Hosts have been required to provide synchronisation for

    such cases. Version 2.9 introduces synchronisation in the plugin,

    making this usage safe. Unfortunately this does not make host code

    safe when using older plugin builds, as the problem and its fix

    are in the plugin side of the SDK. Caution is still required, but

    this fix does allow updated plugin builds to avoid problems with

    some existing hosts

  * Change required C++ language standard from C++98 to C++11. This

    is because of the use of std::mutex in the above fix
