ABI Stability
|
|
====================
|
|
|
|
Botan uses semantic versioning for the API; if API features are added the minor
|
|
version increases, whereas if API compatibility breaks occur the major version
|
|
is increased.
|
|
|
|
However no guarantees about ABI are made between releases. Maintaining an ABI
|
|
compatible release in a complex C++ API is exceedingly expensive in development
|
|
time; just adding a single member variable or virtual function is enough to
|
|
cause ABI issues.
|
|
|
|
If ABI changes, the soname revision will increase to prevent applications from
|
|
linking against a potentially incompatible version at runtime.
|
|
|
|
If you are concerned about long-term ABI issues, considering using the C API
|
|
instead; this subset *is* ABI stable.
