Changelog

1.0.0 - 2026-10-24

The first release.

Added

• One jar for Paper, Purpur, Folia, Spigot, Velocity and BungeeCord (Waterfall too). Minecraft 1.20.6 to 26.3, Java 21 or newer.
• A status message in Discord, sent once and then edited in place every status.interval-seconds (60 by default, 30 at least): online or offline, players, a player list (10 names by default, 0 turns it off), TPS with green, yellow and red markers (18 and 15), MSPT on Paper and Purpur, uptime, version, a copyable server address and the time of the last update. The lines sit under Players, Performance and Server headers, a header goes when all its lines are hidden, and a long player list is cut so that the last-update line always stays. An offline status says since when. Title, a line of your own under it (status.description), colours and icon are set in the config.
• A start and a stop message. After a crash the next start says since when the server was offline.
• Optional join and leave messages, at most 20 a minute by default, the rest in one "and N more" summary. Players in vanish are left out. Off by default.
• One low-TPS warning when the TPS stays below 15 for 5 minutes (both values are set in the config), and no second one until the TPS has recovered and dropped again.
• Network mode for Velocity and BungeeCord: one message about the whole network with each server's state, its players and, when the server runs CoreStatus and has a player online, its TPS, in the same style as the status.
• Each feature can post to its own webhook. Messages in English and Polish, and every text can be changed in messages_en.yml or messages_pl.yml.
• /corestatus reload, /corestatus test and /corestatus status (alias /cstatus), permission corestatus.admin.
• A wrong value in config.yml gives the default and one sentence in the console, and never stops the plugin.
• The guide in English and Polish.

Errors and privacy

• A 401 or 404 from a webhook switches that webhook off until /corestatus reload. A 429 waits as long as Discord says; a 5xx or no connection is retried after 5 s, 10 s, 20 s and so on, up to 10 minutes.
• Sending never runs on the server thread, and stopping the server waits for Discord for 5 seconds at most.
• A webhook token is never written in the console or in data.yml.
• No telemetry, and no connection except to the webhooks you set. The status shows up to 10 player names by default (status.show.player-list: 0 turns the list off); the join and leave messages, which also name players, are off by default.
