Passed directly to GenServer so integer and `:hibernate` responses are supported. - Support closing the connection from the server side. It is best to reserver server side closing for misbehaving connections. - Added callbacks to `Ace.TCP.Server` so that is can be included as a behaviour. ## [0.6.3](https://github.com/CrowdHailer/Ace/tree/0.6.3) - 2016-10-24 ## Changed - Information for new connections is now passed to the server as a map. ## [0.6.2](https://github.com/CrowdHailer/Ace/tree/0.6.2) - 2016-10-24 ## Added - Endpoints can be registered as named processes by passing in a value for the `:name` option. Possible values for this are the same as for the underlying `GenServer`. - The number of servers simultaneously accepting can now be configured. Pass an integer value to the `:acceptors` option when starting and endpoint. Default value is 50. ## [0.6.1](https://github.com/CrowdHailer/Ace/tree/0.6.1) - 2016-10-17 ## Added - `Ace.TCP.Endpoint.port/1` will return the port an endpoint is listening too. Required when the port option is set to `0` and the port is allocated by the OS. ## Fixed - The `handle_packet` and `handle_info` callbacks for a server module are able produce a return of the format `{:nosend, state}`. ## [0.6.0](https://github.com/CrowdHailer/Ace/tree/0.6.0) - 2016-10-17 ## Added - Collect all processes in an endpoint `GenServer` so that they can be started as a unit and only the endpoint is linked to the calling process. This allows for endpoints to be added to supervision tree. ## Removed - `Ace.TCP.start/2` use `start_link/2` instead which takes app as the first argument not the second. ## [0.5.2](https://github.com/CrowdHailer/Ace/tree/0.5.2) - 2016-10-13 ## Changed - The governors will keeps starting server processes to match demand. ## [0.5.1](https://github.com/CrowdHailer/Ace/tree/0.5.1) - 2016-10-10 ## Changed - Send any message that is not TCP related to the `handle_info` callback, previous only messages that matched `{:data, info}` where handled. ## [0.5.0](https://github.com/CrowdHailer/Ace/tree/0.5.0) - 2016-10-07 ## Added - How to hande a tcp connection is specified by an application server module. ## [0.4.0](https://github.com/CrowdHailer/Ace/tree/0.4.0) - 2016-10-06 ## Added - System sends welcome message. - System sends data messages over the socket. ### Changed - Starting a server no longer blocks until the connection has been closed. ## [0.3.0](https://github.com/CrowdHailer/Ace/tree/0.3.0) - 2016-10-04 ## Added - Dialyzer for static analysis, with updated contributing instructions. ### Changed - Nothing, only bumped version due to incorrect publishing on hex. ## [0.2.0](https://github.com/CrowdHailer/Ace/tree/0.2.0) - 2016-10-04 ## Added - ExUnit test suit and single test case. - ExDoc for first hex published version. ### Changed - Restructured to a mix project. Follow new start up instructions in README. ## [0.1.1](https://github.com/CrowdHailer/Ace/tree/0.1.1) - 2016-10-03 ### Fixed - Handle socket closed by client. ## [0.1.0](https://github.com/CrowdHailer/Ace/tree/0.1.0) - 2016-09-18 ### Added - The simplest TCP echo server. - All code exists in a single source file `server.ex`. - Documentation is added to the [source code](https://github.com/CrowdHailer/Ace/blob/master/server.ex).
