Late
2013 Steinberg announced that the Software Development Kit (SDK) for VST 2
would no longer be maintained and would only be available as subset of the
VST 3 SDK. Five years down the line and this transitional phase is now also
coming to an end.
From
October 2018 onward Steinberg are closing down the second version of VST for
good. While the VST 2 SDK has been unavailable, and so have maintenance and
technical support, the subset within the VST 3 SDK will also be omitted.
VST 2
compatibility with VST hosts will remain, however, Steinberg recommend to
root for the latest version of VST. VST 2 was introduced in 1999 and since
then the technology has evolved dramatically. Since 2008, the SDK for the
third iteration of VST, VST 3, has been available and since then efforts are
focused entirely on the further development of VST3.
