Describe the release item

The test transport_tcp_concurrent in github CI on windows panics with message

thread 'transport_tcp_concurrent' panicked at io\zenoh-transport\tests\unicast_concurrent.rs:316:43:
called `Result::unwrap()` on an `Err` value: error scheduling message! at io\zenoh-transport\src\unicast\universal\transport.rs:408.

see windows run, line 2785, https://github.com/eclipse-zenoh/zenoh/actions/runs/9588701994/job/26441248363

The failure occurs only if test is executed separately from other tests, otherwise it's just terminated by timeout. The PR for testing this: https://github.com/eclipse-zenoh/zenoh/pull/1172

I was unable to reproduce this locally

It seems the CI has been happy for a while now and the test didn't fail anymore. Closing the issue. Feel free to reopen it if it's still relevant.
