Currently, I only provide software support for the latest stable release and the latest beta. For example, if the latest stable version is 1.1.2, I will provide software support for 1.1.x and 1.2.0-beta.x. If I release a version that adds incompatibility with an old version of FL Studio, I may support that branch for a little while longer.
Although for a project of this nature, I do not expect there to be any security vulnerabilities, if you find any security issues, please contact me at [email protected], or on Discord at HDSQ#2154.
