Version 3.7.4 is now available.

[janiversen]

Version v3.7.3 contains a critical bug, that makes the sync. client disconnect/connect with every request, thus adding a large delay,
due to that fact it was decided to release version 3.7.4 a bit ahead of time.

v3.7.4, contains a number of bug fixes, and especially a new broadcast handling, where slave=0 is treated just as another slave, a new parameter "no_response_expected" is added to allow for broadcasting requests.
