**Noteworthy changes in version 3.0.0** (2024-06-18)
* API change: For new code, which uses libassuan with nPTH, please
use gpgrt_get_syscall_clamp and assuan_control, instead of the
system_hooks API. Use of ASSUAN_SYSTEM_NPTH is deprecated with new
API version 3. If it's really needed to keep using old
implementation of ASSUAN_SYSTEM_NPTH, you need to change your your
application code, to define
ASSUAN_REALLY_REQUIRE_V2_NPTH_SYSTEM_HOOKS before including
<assuan.h>. For an application which uses version 2 API
(NEED_LIBASSUAN_API=2 in its configure.ac), use of
ASSUAN_SYSTEM_NPTH is still supported. [T5914]
* New function assuan_control. [T6625]
* New function assuan_sock_accept. [T5925]
* New functions assuan_pipe_wait_server_termination and
assuan_pipe_kill_server to support abstraction of process. [T6487]
* Windows support for sendfd/recvfd. [T6236]
* Implement timeout in assuan_sock_connect_byname. [T3302]
* No support for WindowsCE, any more. [T6170]
* New socket flags "linger" and "reuseaddr". [rA87f92fe962]

assuan_sock_accept NEW.
assuan_pipe_wait_server_termination NEW.
