Noteworthy changes in version 3.0.0 (2024-06-18) [C9/A0/R0]
------------------------------------------------

 * 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]

 * Interface changes relative to the 2.5.0 release:

OpenWrt package maintainer note:
autotools is trying to be smart with detecting gpgrt-config, let's
try to be *even smarter* and force it to use the version in
STAGING_DIR...
