⁠Appendix B. Changes in Version 3.0
The Symt ab API library has been improved to support access to inline functions.
Checks are now performed and errors returned in case the instrumentation requires traps, but the
user has disabled them.
The generation of XMM registers save and restore has been improved, and function-call snippets
have been optimized as a result.
Block-level instrumentation performance in shared code has been improved.
Whenever possible, checks are now performed on parameter and return-value snippets.
Symbol visibility is now properly controlled, so that only public D yn in st functions and variables
are exposed to users.
