How stable are key derivation functions like HKDF?

[TC]

Hi, I am planning to use HKDF in my project to derive keys to use as
data-encryption keys to encrypt persistent data.  Is this kind of function
version protected?  I fear that if any changes happen to these functions
they are going to break backward compatibility, is that a concern?

Thanks!
