1.7.4

This patch release expands the mechanism of client-server interactions by allowing batch subscription keep-up and cancel requests.

This reduces the amount of request-response pairs greatly, lowering the load on the webserver.

Automatically, the client will always use the batch versions of the requests. However, the server may still receive singular requests for compatibility. Therefore, when migrating to this version, the server must be updated first and the clients should follow.

See the PR #170 for more details.
