NuVotifier

This is a minor bug fix release. Changes: · Relocate Gson to potentially fix BungeeCord chat API issues (i.e. SPIGOT-6056) · Fix disabling the plugin messaging fallback server functionality on Velocity. · Do not re-register raw data channel on Sponge

NuVotifier 2.7.1 is now available. This is a bug-fix release. Changes from NuVotifier 2.7.0 Fixes a proxy vote forwarding not working when Epoll is in use.

This release adds some new features, fixes a number of bugs, and improves the security and performance of NuVotifier. All servers are encouraged to upgrade. This release has been tested with Spigot 1.16.1. Changes since 2.6.0: · Make /(p)testvote available on all platforms. This allows you to test your vote listener setup. · Make /(p)nvreload more consistent - /nvreload is used for servers and /pnvreload is used for proxies. · Warn if no vote listeners were found for Bukkit. · Improve compatibility with Sponge and certain Bukkit forks by removing usages of Guava. · Improve security of NuVotifier by hardening it against certain DoS attacks. · Improve scalability of NuVotifier by allowing it to use more threads and implementing Epoll support for Linux. · Add native reloading support for BungeeCord, Sponge, and Velocity so NuVotifier reloads when you reload the configuration on these platforms. · Add extra debug logging for successful plugin message vote forwarding. · A number of minor bug fixes, including improvements to Velocity and Sponge support. This is the first release of NuVotifier from me ( @Tux) in some time - I hope the wait has been worth it!

Fixes a problem when specifying an empty server list. This will be the last release until 3.0.0.

Features: · A negative port for bukkit and sponge servers will disable the external NuVotifier port. · Migrate to Gradle · Migrate to Drone CI Fixes: · Fixes an issue where we used to rely on a direct buffer in sponge, which was removed in 7.0 · Fixes an issue introduced in 2.3.6 on bungeecord where file caching of votes straight out did not work.

The last release had a bad verison number. The only change is correcting the version.

This update only removes support for the enableExternal option in config.yml. No other changes have been made. See this forum post for justification.

· Reduce issues with large vote file caches. · Log successful vote attempt IPs when debug mode is enabled. · Other bug fixes.

This release fixes various anomalies that have been uncovered, as well as various improvements to the codebase.

· Fix "username too long" errors. · Fix debug messages to detect the proper protocol version. · CONFIG CHANGE: Proxy servers need to be changed from key -> token.

· Fixed forwarding when forced to forward to the server that the player was on. · Added filtering for servers. · Sponge support added.

· Vote parsing for protocol v1 packets has been made less strict in order to appease certain broken voting websites. · You can now disable protocol v1 parsing in the configuration. · Protocol v2 key checks are now performed using a more secure way of performing equality checks that is more immune from timing attacks. · Votes forwarded with plugin messaging can now be sent to a fallback server if the player voting isn't online.

· Introduced proxy vote forwarding. NuVotifier can forward votes from your BungeeCord NuVotifier to another NuVotifier server using the NuVotifier protocol. · Fixed compatibility with Java 7. We strongly recommend upgrading to Java 8. · Fixed misleading null address bug when you can not bind to a port.

Vote forwarding has been fixed.

Vote forwarding support has been added to NuVotifier. NuVotifier can now forward votes from your BungeeCord to all of your Bukkit servers easily. Currently, votes are forwarded over plugin messaging, but we've made this system reliable even when players are not on your server. Configuring vote forwarding is simple. You must configure it on both your Bukkit and BungeeCord servers. Example configurations: · BungeeCord: https://github.com/NuVotifier/NuVot...ecord/src/main/reso… · Bukkit: https://github.com/NuVotifier/NuVotifier/blob/master/bukk…

Ported NuVotifier to BungeeCord.
