• WOLFTPM_LIBRARY_VERSION was bumped to 18:0:0, which (per the versioning notes immediately below) implies interfaces were removed/changed because age is reset to 0 (ABI break / SONAME bump). If 4.1.0 is intended to be ABI-compatible and only add new APIs, age should typically be incremented instead of reset. Please confirm the intended ABI compatibility for this release and adjust the libtool version accordingly to avoid an unnecessary SONAME change for downstream packagers.

WOLFTPM_LIBRARY_VERSION=18:0:0
