Release 2.4.1

* Started porting to Velocity

* Heading down into the rabbit hole.

This begins a refactor of NuVotifier to more easily support other platforms
in the future. Much of this work is required to ensure feature-for-feature
compatibility between NuVotifier for BungeeCord and NuVotifier for Velocity.

Doesn't compile!

* Fixes the compile, adds SLF4J stuff.

Far from done!

* Independent Votifier server bootstrap

* Use independent Votifier server bootstrap across all platforms

* Laying the stones for Velocity forwarding

* Add vote forwarding to Velocity port

* It compiles, enables, and accepts a vote! (Still unfinished.)

* Vote forwarding works.

* Fix Sponge plugin message forwarding config

* Work around BungeeCord problems:

- JsonObject#keySet() is missing in Gson 2.8.0
- Bungee's "special" logging situation

* Remove Velocity repo

* Resolve issues that came up during review

* Handle a null error consumer

* Make the setup documentation proxy-agnostic

* Fix grammar.

* Add ParallelBlock repo

+# NuVotifier
+
+NuVotifier is a Bukkit plugin whose purpose is to be notified (aka *votified*)
+when a vote is made on a Minecraft server top list for the server.  NuVotifier
+creates a *lightweight* server that waits for connections by Minecraft server
+lists and uses a simple protocol to get the required information.  NuVotifier is
+*secure*, and makes sure that all vote notifications are delivered by authentic
+top lists.
+
+## Why fork Votifier?
+
+Votifier has lagged in activity, has severe security flaws in its protocol, and
+is vulnerable to denial of service attacks.
+
+## Is NuVotifier a drop-in replacement for Votifier?
+
+Yes! Except for some minor non-breaking changes (look into the [technical qa
+docs](docs/technical_qa.md) for more info), NuVotifier is 100% compatible with
+the old Votifier with many more features.
+
+# Documentation / Configuration Guide
+
+All documentation is located under the [docs](docs/) directory. A server admin
+configuration guide is available [here](docs/usage.md).

-# NuVotifier
+This document outlines some of the technical reasons for a new NuVotifier.
 
-NuVotifier is a Bukkit plugin whose purpose is to be notified (aka *votified*) when a vote is made on a Minecraft server top list for the server.  NuVotifier creates a *lightweight* server that waits for connections by Minecraft server lists and uses a simple protocol to get the required information.  NuVotifier is *secure*, and makes sure that all vote notifications are delivered by authentic top lists.
-
-## Why fork Votifier?
-
-Votifier has lagged in activity, has severe security flaws in its protocol, and is vulnerable to denial of service attacks.
-
-### Is NuVotifier a drop-in replacement for Votifier?
-
-Yes. NuVotifier is compatible with Votifier server lists and Votifier listeners, with some differences:
-
-* The `Vote` object's setters are deprecated.
-* Support for standalone vote listeners (`.class` files) has been removed, as handling `VotifierEvent` is more flexible.
-
-### Why a new protocol?
+# Why a new protocol?
 
 The old Votifier protocol has three major flaws, which we feel are corrected in the new protocol.
 
@@ -21,39 +8,20 @@ The old Votifier protocol has three major flaws, which we feel are corrected in
 * The canonical Votifier protocol is vulnerable to replay attacks.
 * The canonical Votifier is one key for all clients, which is weak. While NuVotifier still supports a default key (for the less paranoid), this ability can be disabled and force per-server keys.
 
-## Configuring NuVotifier
+# Is NuVotifier a drop-in replacement for Votifier?
 
-NuVotifier configures itself the first time it is run. If you have an existing Votifier configuration, NuVotifier will copy it over and use it.
+Yes. NuVotifier is compatible with Votifier server lists and Votifier listeners, with some differences:
 
-If you want to customize NuVotifier, simply the edit `./plugins/(Nu)Votifier/config.yml` file.
+* The `Vote` object's setters are deprecated.
+* Support for standalone vote listeners (`.class` files) has been removed, as handling `VotifierEvent` is more flexible.
 
-An in-depth configuration guide is located in `usage.md` of this repository.
-
-### Tokens
-
-In `config.yml`, you will notice a `tokens` section. NuVotifier has a new protocol version that requires tokens. The `tokens` section can be used to easily grant or revoke access to a server list based on the keys it uses.
-
-### RSA Keys
-
-RSA keys for use with the old Votifier protocol are available under the `plugins/(Nu)Votifier/rsa` directory.
-
-### Vote Forwarding
-
-Starting from NuVotifier 2.2, there is a feature to forward votes from NuVotifier running on BungeeCord to your Bukkit servers without complicated setup.
-
-You must enable the feature on both your Bukkit and BungeeCord servers. This feature is still in beta but is stable.
-
-## Building NuVotifier
-
-NuVotifier can be built by running `mvn clean package` from within the root directory of NuVotifier. A universal Bukkit/Spigot & BungeeCord plugin will be built to `universal/target/nuvotifier-universal-{version}.jar`

Each string is delimited by the newline character `\n` (byte value 10).  The `space` block is the empty space that is left over, **the block must be exactly 256 bytes** regardless of how much information it holds.

+This document outlines how to configure NuVotifier for a variety of different
+configurations. It should be used by server administrators looking to set up
+NuVotifier on their network.
+
+# Key vs Token
+
+This document uses the terms `token` and `key`. These are two separate terms,
+and it is important to understand the differences.
+
+## Key
+
+Keys in terms of NuVotifier refer to the old Votifier style RSA keys. They
+are typically distributed as a pair of files - a public and private key. When
+dealing with RSA keys, you can share your public key with server lists, but make
+sure to keep your private key safe with you. You can find these keys
+auto-generated under `plugins/(Nu)Votifier/rsa/`, where your public key is
+named `public.key`, while your private key is labeled `private.key`. Make sure
+not to separate the two, as they won't work together.
+
+## Token
+
+Tokens in terms of NuVotifier refer to a new short string of characters. This
+string of characters is secret, and should never be exposed to anyone but you or
+server lists which support NuVotifier voting (check with the server list
+first). Tokens are most commonly used internally within a network for use when
+using the proxy vote forwarding method.
+
+# Single Server Configuration (Bukkit / Spigot / Sponge)
+
+You will want to set up your server using these instructions when you only have
+one Minecraft server (Bukkit / Sponge). These are the most trivial installation
+steps.
+
+## Installing the plugin on a server
+
+To install NuVotifier, you should get a copy from one of the following
+locations:
+
++ [Github](https://github.com/parallelblock/NuVotifier/releases) - Official
+  release location
++ [SpigotMC](https://www.spigotmc.org/resources/nuvotifier.13449/) - SpigotMC
+  release mirror
++ [repo.parallelblock.com](https://repo.parallelblock.com/repository/public-raw/nuvotifier/nuvotifier.jar) - ParallelBlock CI 'hot off the presses' releases
+
+The NuVotifier jar should then be placed within the `plugins/` folder of your
+Minecraft server. When you then start your server, NuVotifier will generate
+the necessary configuration and initial keys for you.
+
+## Configuring the plugin
+
+When running in a single server configuration, NuVotifier's default
+configuration works well. The only value which you may need to change is the
+`port` configuration value - this specifies the port on which NuVotifier
+listens to new votes. This port cannot be any port you are already using. For
+example, if Minecraft is running on the default port (25565), you cannot set
+`port` also to 25565. Make sure port is a number from 1-65535.
+
+You can then add your server to server lists using the port you configured while
+also supplying your public key. At this point, you should be able to send a test
+vote to your server!
+
+# Multi-server / Network configuration
+
+You will want to use these instructions when you have more than one server and
+are using a Minecraft proxy (such as BungeeCord, LilyPad, or Velocity).
+
+## Single-Proxy BungeeCord/Velocity Networks
+
+When running a single-proxy network, NuVotifier is able to operate as both
+a vote receiver (emitting events for proxy based vote listeners) as well as
+a vote forwarder. NuVotifier's vote forwarding logic is also advanced enough
+to be used in a wide variety of ways.
+
+### Installing the plugin on the servers
+
+NuVotifier should be installed on each of the servers you wish to process votes
+on, as well as the proxy server. The proxy's NuVotifier server will act as the
+public facing Votifier instance, where as the Minecraft servers will instead
+receive votes forwarded from the proxy's NuVotifier.
+
+Like the single server installation, you can download NuVotifier at any one of
+the following locations:
+
++ [Github](https://github.com/parallelblock/NuVotifier/releases) - Official
+  release location
++ [SpigotMC](https://www.spigotmc.org/resources/nuvotifier.13449/) - SpigotMC
+  release mirror
++ [repo.parallelblock.com](https://repo.parallelblock.com/repository/public-raw/nuvotifier/nuvotifier.jar) - ParallelBlock CI 'hot off the presses' releases
+
+The plugin should then be placed in the `plugins/` directory of the Bungeecord
+server as well as each of the Minecraft servers.
+
+### Vote Forwarding
+
+The following sections describe how vote forwarding works. Vote forwarding is an
+advanced configurable operation, and requires a lot of configuration to get
+correct.
+
+### Plugin messaging based forwarding
+
+This section describes how to set up plugin messaging forwarding. This is
+recommended if you have just one proxy, however this may also work with
+some exceptions in multi-proxy networks.
+
+First off, we should configure each of the Minecraft servers. Open each of the
+servers' NuVotifier configurations. Each one should have `method` under the
+`forwarding` configuration section set to `pluginMessaging`. Under the
+`pluginMessaging` configuration section, `channel` is set to `nuvotifier:votes`.
+Since 1.13, Spigot has decided that channels must now contain a colon. While
+this is a completely senseless change, it is easier to simply conform and change
+the channel name.  This is a safe default (and is protected from injection by a
+hacked Minecraft client), but feel free to change it. If you choose to change
+it, make sure you change it everywhere all around your network!
+
+Since we are receiving forwarded votes through plugin messaging and not through
+network ports, we should set `port` on each of the Minecraft servers to -1. This
+will disable NuVotifier's port, while still allowing it to receive forwarded
+plugin messaging votes. This will only work when using plugin messaging!
+
+Since we have all of that configured, we can now move to the proxy's NuVotifier
+configuration. It is once again located under `plugins/NuVotifier/` directory
+(`config.yml` for BungeeCord, `config.toml` for Velocity). Like the single server,
+`port` should be set to an unbound port. The default `8192` works well, however
+you may have to change it depending on your hosting provider.
+
+Since we are using plugin messaging based forwarding, lets set `method` under
+`forwarding` to `pluginMessaging`. Make sure that `channel` is the same channel
+that you configured your servers to listen to - if you didn't change this value,
+then the default will work.
+
+NuVotifier saves when it can't immediately forward in a user defined cache. In
+almost all installations this should be `file`, however, some installations may
+instead want `none` or `memory`. If you don't know, the `cache` should be set to
+its default, `file`.
+
+By default, NuVotifier will forward the vote to all of the connected Minecraft
+servers (all servers you can get to when typing /server). You can manually
+exclude some of these servers by first uncommenting `excludedServers`, then
+adding the server's name to the `excludedServers` list. After adding, NuVotifier
+will not send any votes to this server. If you only send the vote to the server
+the player joined, these servers are ignored.
+
+NuVotifier can also selectively send the vote to only the server which the
+player has joined. This option can be turned on by setting
+`onlySendToJoinedServer` to true. When this option is on, the vote will attempt
+to go to the server which the player is currently on. If the player is currently
+not on a server (offline), then NuVotifier will then attempt to send the vote to
+the `joinedServerFallback`. If the vote cannot be sent to the
+`joinedServerFallback`, then the vote is saved in the cache until the vote can
+be sent to the `joinedServerFallback` server - note this will not send it to the
+next server the player joins! If you do not want a fallback server and would
+rather the vote be applied when the player next joins, set
+`joinedServerFallback` to `''`. This will cause NuVotifier to save the vote
+until the player joins again.
+
+By default, votes are saved for 10 days in the cache. This time can be increased
+or decreased by changing the `voteTTL` field. This number can be as high or low
+as you want. It is measured in days within the cache.
+
+### Proxy based vote forwarding
+
+In more complex network situations, it may be required to instead use the proxy
+based vote forwarding. This configuration is less flexible and more difficult to
+set up properly - most people should use plugin messaging based forwarding.
+Proxy based forwarding does not support vote caching or advanced forwarding
+configurations. If you cannot use plugin messaging forwarding, then the
+following section will describe how to set up proxy based vote forwarding. If
+you still require advanced forwarding features or more advanced behaviors, it
+may be worthwhile to write your own plugin to perform the proper forwarding logic
+(you will know if you need to do this).
+
+In proxy based vote forwarding, one of your proxy servers acts as the head vote
+receiver. This server will be the one you configure the voting websites to
+vote to. You can set up multiple vote receivers and load balance between them,
+however this configuration has limited benefit and is probably more work than it
+is worth. Instead of communicating through plugin messaging like the plugin
+messaging forwarding strategy, proxy forwarding instead acts like a voting
+website to each of the backend servers and duplicates the vote it receives to
+each of the backend servers it is configured with.
+
+First, we will set up all of the Minecraft servers before setting up the head
+vote receiver. For each of the servers, NuVotifier should be configured to bind
+to an unused port. This port must be valid. If you have multiple Votifiers on
+the same IP/server, make sure that the port which you are using between
+NuVotifier instances are different. Remember the the port number as we will need
+it later to insert into the proxy NuVotifier configuration. In addition to the
+port number, you will also need the default token - this is the string auto
+generated by NuVotifier under the `default` key under `tokens`. Since we are using
+proxy forwarding, change `disable-v1-protocol` to true - we will only be using the
+new NuVotifier protocol within our network (vote receiver -> minecraft server).
+Once all configured, that is all we need to do. The rest of the defaults will work.
+
+Now we will configure the vote receiving NuVotifier proxy server. The port
+should be configured as described many times above, being a unique port. Instead
+of setting `method` to `pluginMessaging` like above, we will set `method` to
+`proxy`. This will tell NuVotifier that we instead want to proxy the votes
+instead of forward them through plugin messaging channels.
+
+The last step is to set up the proxy forwaring settings. Under the `proxy`
+section is a place to enter each server. Create a unique name for each of the
+server's you will be forwarding votes to. The default proxy NuVotifier
+configuration already has two Minecraft servers filled in - Hub and Hub2. You
+should replace these with your own servers - the names of the servers do not
+matter. Under each of these servers, we need to configure `address`, `port`, and
+`token`. `address` is the IP address of the Bukkit/Sponge server. This may be
+`localhost` or `127.0.0.1` if the Minecraft server is on the same physical
+server as the vote receiving NuVotifier server. `port` is the port of the
+Bukkit/Sponge NuVotifier server. `token` is the default token of the
+Bukkit/Sponge NuVotifier server. This can be found within its configuration,
+usually under the `token` section. Once the servers are configured, NuVotifier
+will forward all votes it receives to the servers configured under the `proxy`
+section.
+
+# Debugging NuVotifier
+
+NuVotifier can be difficult to set up in some configurations. If you find you
+don't know what is wrong, you may want to try setting `debug` in each of the
+server's NuVotifier configurations to `true`. This will increase logging within
+your console. 
+
+# Reloading NuVotifier
+
+For Bukkit and Bungee, you may reload NuVotifier through the `/nvreload` command
+in your console only - this command will not work in-game by design. Make sure to
+ensure that it completed correctly before assuming NuVotifier works!
+
+# Default Configurations
+
+If you find you have messed up NuVotifier beyond repair, you can grab a default
+configuration from the following locations (depending on the server it is
+installed on):
+
++ [Bukkit](https://github.com/parallelblock/NuVotifier/blob/master/bukkit/src/main/resources/bukkitConfig.yml)
++ [Sponge](https://github.com/parallelblock/NuVotifier/blob/master/sponge/src/main/resources/com/vexsoftware/votifier/sponge/spongeConfig.yml)
++ [Bungeecord](https://github.com/parallelblock/NuVotifier/blob/master/bungeecord/src/main/resources/bungeeConfig.yml)
+
+You can also regenerate this configuration by deleting the old configuration and
+restarting the server.

-# Votifier v1 vs NuVotifier v2 Protocols
-
-NuVotifier introduces a more secure and failure tolerant protocol for sending votes. In this document, this new protocol
-will be referred to as v2. NuVotifier also supports the legacy Votifier protocol (using public key encryption). In this document,
-the legacy protocol will be referred to v1. As of writing, most if not all vote websites still use v1.
-
-# Configuration
-
-## Enabling the NuVotifier Server port
-
-NuVotifier allows for the server port to be turned off when NuVotifier is only being used to forward votes. This is only
-an option on Bukkit based servers, since it would not make logical sense for the port to be turned off on Bungee servers.
-
-If you are receiving votes from a server list directly on the server in question (votes are not being forwarded through plugin
-messaging), or if votes are being forwarded through the `proxy` method, then `enableExternal` should be set to true. Only
-if you are receiving forwarded votes from your bungee through the `pluginMessaging` forwarding method should `enableExternal`
-be set to false.
-
-## Port Configuration
-
-One of NuVotifier's functions is acting as a vote server (receiver). The IP for NuVotifier to bind to is configured
-by the `host` and `ip` configuration values within the config.yml files within the NuVotifier plugin folder.
-Most times, you will want this `host` value to be set to `0.0.0.0` or your server's ip. `0.0.0.0` will bind to all
-ip ports on your machine, while specifying a certain IP will only bind to that ip. If you don't know what to set this
-to, `0.0.0.0` is a safe bet. By default, NuVotifier listens on port 8192. This is the same as the default Votifier port.
-If you change this, you will have to remember this when setting up forwarding or server lists.
-
-## Debug mode
-
-When first setting up NuVotifier, you will probably want debug mode to be enabled. This prints extra information to the
-console, ensuring that votes are being processed as they should. If you are experiencing an error, or having issues with
-votes being processed, you should first look to enable this. Debug mode can be turned on by setting `debug` in the config.yml
-to true.
-
-## Tokens vs Public Key
-
-As explained earlier, NuVotifier supports 2 different protocols for receiving votes, v1 and v2. v1 uses the private and public
-key pair located in `rsa/` in NuVotifier's plugin folder. When setting up voting websites, the public key, `rsa/public.key`
-should be used. When setting up the `proxy` forwarding method, tokens should be used.
-
-Making a new token is as easy as adding another entry into `tokens` with the serviceName as the key and whatever string you want
-as the value. You can usually find the serviceName of a vote provider on their setup page if they use v2.
-
-Unless a website specifies it, you should assume that the website is using v1, and you should enter your `rsa/public.key`.
-
-## Forwarding
-
-NuVotifier allows for various methods for forwarding the vote from an upstream Bungeecord instance. Currently, 2 methods
-are supported: `proxy` and `pluginMessaging`. These are configured through the `forwarding` configuration section in your
-config.yml files.
-
-### Plugin Messaging Based Forwarding
-
-Plugin Messaging based forwarding works by sending a forwarded vote over Minecraft's plugin messaging system. NuVotifier
-is only capable of forwarding the vote if a player is on each backend server through the BungeeCord running NuVotifier.
-Plugin Messaging can be enabled by setting `method` in `forwarding` to `pluginMessaging`. You may also set the plugin messaging
-channel NuVotifier is to use by setting `channel` in the `pluginMessaging` section. This may be whatever you want, but it
-must be the same on your BungeeCord as well as your backend Bukkit servers. If they are not the same, the backend will not
-be able to receive the vote.
-
-#### Filtering servers
-
-If you only wish to send votes to some servers, but not all, there is a section within `pluginMessaging` called `excludedServers`.
-By default, this section is commented out, and will never filter out any servers. If you wish to filter out servers, uncomment
-this list and fill it with the names of servers you do not want to send votes to.
-
-#### Plugin Messaging Vote Caching
-
-In the event that the backend server does not have anyone on it from the BungeeCord instance, the vote will need to be cached
-until a player joins and the vote may be sent. There are 3 options for caching, however one is only suitable for actual
-production.
-
-##### Memory Vote Caching
-
-For votes to simply be cached in memory, you can set the `cache` setting of the `pluginMessaging` section of your BungeeCord's
-NuVotifier's config.yml to `memory`. This stores votes in memory. The votes are lost when the BungeeCord server shuts down.
-This is suitable for testing, but not for production system.
-
-##### File Vote Caching
-
-Votes can also be cached in a file located in the NuVotifier plugin folder. To enable this, you can set `cache` to file.
-If you want to change the file location from the default, you can set this under the `name` config under the `file` section.
-This caching method is suitable for most people.
-
-##### No Caching
-
-Caching can also be turned off. This is the default option. You can do this by setting `cache` to `none`. This is also not
-recommended, and is only suitable for a certain number of setups.
-
-### Proxy Based Forwarding
-
-You can also forward votes using the proxy method. This will cause the BungeeCord to act as a voting websites, sending votes
-to each server's NuVotifier port. To enable this method, you must set the `method` under `forwarding` to `proxy` in your
-BungeeCord config.yml. Within the server's config.yml, `forwarding` should be set to `none`.
-
-For each server you wish to forward to, you must add each to your BungeeCord config.yml under the `proxy` section of `forwarding`.
-For each, you must specify the ip address (`address`), port (`port`) and token (`key`). Each backend Bukkit server should have
-1 default token under the `tokens` section. This is the token that should be used as the token for the `key` in that server's
-section within the `proxy` section. If the server is on the same server (same ip) as the BungeeCord server, you may
-use the `127.0.0.1` or `localhost` address, setting both the `proxy` forwarding address and Bukkit config.yml address to it.
-
-In order for vote proxying to work, the backend server __must__ have `enableExternal` set to true. If it is set to
-false, the Bungee server will not be able to forward the vote. 
-
-
-## Default Configurations
-
-The default configuration for Bukkit can be found [here](https://github.com/NuVotifier/NuVotifier/blob/master/bukkit/src/main/resources/bukkitConfig.yml),
-for BungeeCord [here](https://github.com/NuVotifier/NuVotifier/blob/master/bungeecord/src/main/resources/bungeeConfig.yml),
-and for Sponge [here](https://github.com/NuVotifier/NuVotifier/blob/master/sponge/src/main/resources/com/vexsoftware/votifier/sponge/spongeConfig.yml).
-
-
-## Testing
-
-There is a free resource for testing your NuVotifier setups at [ibj.io/v](https://ibj.io/v). If you are setting up your
-network or server and want a server to get test votes on, you are more than welcome to use it.
-
-
-## Basic Setups
-
-### Single Server Quickstart
-
-A single server setup should have `enableExternal` set to `true`, and `forwarding.method` set to `none`. The IP and port
-should also be set to appropriate values. For server lists, you should use the public key found in `rsa/public.key`.
-
-## Advanced Setups
-
-### Multi BungeeCord Setups
-
-Using NuVotifier with multiple BungeeCords is a more tricky setup. You can use one of your player-facing proxies for the
-NuVotifier server, or use a separate one. You are not guaranteed to have players on all of your servers to allow votes to
-be dispatched, so proxy forwarding (requiring `enableExternal` set to `true` on your Bukkit servers) is highly recommended.
