libnice 0.1.23 (2025-11-26)

API: Added option NICE_AGENT_OPTION_CLOSE_FORCED to not wait for TURN when

closing asynchronous

Reject invalid remote candidates with priority=0
Add missing mutex in tcp-bsd socket
Add buffer list support to nicesrc
Avoid dropping packing in nicesink, retry instead
Only create a new NiceCandidate if a socket can be opened, as it is
a somewhat costly operation.
Many new tests
Fix leaks
Fix various test flakiness

Adjust dependencies.

Remove pkg-plist in slave port.

Does not work, setting PLIST_FILES does not empty the MASTERDIR
plist. (truckman)

BUILD_WRKSRC and INSTALL_WRKSRC do not work with meson. (truckman)

When building with ssl, gnutls is not needed. (truckman)

These two ports should probably use SUBPACKAGES.
