wolfSSL is announcing a long term support (LTS) version of the wolfSSL library. The goal of this product will be to provide users with fully ABI compatible releases of wolfSSL that are secure against all known vulnerabilities. Patches for vulnerabilities will be backported to the LTS branch in an ABI compatible way to guarantee security and stability.
ABI (Application Binary Interface) is a low-level interface that defines how functions and data structures are accessed in machine code. ABI specifies how parameters are passed to functions, how return values are retrieved, and how data structures are arranged in memory. Guaranteeing ABI stability means that compiling a newer version of the library with the same configuration will work with programs linked against an older release.
wolfSSL LTS will provide users with a stable and reliable library that can be kept up to date with no additional headache. Your programs will always be compatible with the latest wolfSSL LTS release and will be safe from discovered vulnerabilities. Separating out a LTS branch will allow us to continue developing and improving wolfSSL without the strict restrictions of ABI backwards compatibility. Users will be able to choose the appropriate version for them based on their individual priorities.
wolfSSL LTS, like all of our libraries, will be offered under a dual-license model. GPL will be available for open source users and a commercial license will be available for customers integrating it in commercial products. Additional limited backporting services will also be available for customers.
