0.13.1

For a server running v0.13.0, this is a drop-in maintenance release. Gameplay, commands, permissions, config keys and stored data are unchanged, and usage reporting sends the same information and respects the same opt-out switches as before.

Changes

Usage reporting

• Updated the bundled usage-reporting client to version 0.6.1. What Fiefs reports and how it decides whether to report are unchanged.
• The usage-reporting details link now points to https://danielstephenson.dev/usage-reporting. The new link appears in the startup log message, the comment in config.yml and the header of a newly created plugins/trace/config.yml. An existing plugins/trace/config.yml is left as it is.

Version

v0.13.0 → 0.13.1 — PATCH. Mechanical floor from comparing the two jars: PATCH. Judgment: The only code change updates the bundled trace usage-reporting client from 0.5.0 to 0.6.1. That update adds an installIdFile option and an installIdFromFile helper, but Fiefs calls neither, so the plugin still reports the same data, resolves the same server ID and honours the same opt-outs. The other changes only replace the 'details' link in a config comment, in a log message and in the header of a newly created plugins/trace/config.yml. No data format, command, config key, permission or plugin behaviour changes, so the patch floor stands.

• no interface or storage difference observed between the jars

0.13.0

For a server running v0.12.1, this is a drop-in upgrade with no config or data changes required. Players now get told why fief protection blocked them, /fi info with no argument works again, and Minecraft 26.3 is supported. If usage reporting is on, the plugin now adds a random server ID to plugins/trace/config.yml and sends it with its usage events. The ID identifies no player, account or IP address.

Changes

Gameplay

• When fief protection blocks breaking, placing, interacting, using buckets or handling item frames and hanging entities, the player is now told which fief owns the land. To avoid chat spam, each player gets the message at most once every two seconds (#210).
• /fi info with no argument now shows your own fief, as the help text says. Before, it did nothing. When run from the console, it now says only players can use it (#208).

Compatibility

• Added support for Minecraft 26.3 (#206).

Usage reporting

• If usage reporting is enabled, the first start adds a random server-id line to plugins/trace/config.yml, and every usage event carries that ID so distinct servers can be counted. The startup message and the comments in config.yml now mention it (#204, #205). If reporting is turned off, nothing is generated or written. Delete the line to get a new ID.

Commands

• /fi config set no longer gives special double-quote handling to denyUsageMessage and denyCreationMessage. Neither was ever a real config option, so the change has no practical effect (#202).

Version

v0.12.1 → 0.13.0 — MINOR. Mechanical floor from comparing the two jars: PATCH. Judgment: This release adds new behaviour that the mechanical check only partly sees. Players now get a chat message when fief protection blocks an action (#210). On its first enabled start, the plugin also writes a new server-id line to plugins/trace/config.yml and sends it with every usage event (#204), which counts as new data written. Nothing existing breaks: no data format, permission or meaningful config key changes, and the dropped denyUsageMessage/denyCreationMessage parsing (#202) applied to names that were never real config options. Minor is enough; major isn't warranted.

0.12.1

This is a small, drop-in update for servers running v0.12.0. It fixes /fi help so that it shows the first help page when no page number is given. It also makes a minor change to usage reporting: every event now includes the plugin version. Commands, permissions, configuration and saved fief data are unchanged.

Changes

Commands

• /fi help with no page number now shows the first page of help. Before, it printed nothing. (#195)

Usage reporting

• Every usage event now includes the plugin version, including the event sent when a command is used. Before, only the startup event included it. No information about players or the server is added, and the existing opt-outs (usage-reporting.enabled, the server-wide plugins/trace/config.yml, and the TRACE_USAGE_REPORTING / DO_NOT_TRACK environment variables) work the same as before. The explanation in the default config.yml has been updated to match. (#196)

Version

v0.12.0 → 0.12.1 — PATCH. Mechanical floor from comparing the two jars: PATCH. Judgment: The mechanical floor of patch stays. This release has one user-facing bug fix: /fi help with no page number used to print nothing and now shows page 1. It also changes what usage reports contain: command events now carry the plugin version, which startup events already sent, so no new kind of information leaves the server and no on-disk data, config key, permission or command argument changes. The TraceClient.builder signature change is in the plugin's own bundled copy of the reporting client, which other plugins aren't expected to use, so it doesn't justify a major bump. #198 only adds tests.

0.12.0

Fiefs is a Bukkit/Spigot plugin for servers that run Medieval Factions. It lets faction members create smaller sub-territories called fiefs inside their faction. A fief has its own members, description and flags, and can claim chunks of land. Players can invite others to a fief, transfer ownership of it, and look up which fief a player belongs to. A fief is disbanded if its owner leaves the faction. Install it if your server already uses Medieval Factions and you want a layer of land and membership below the faction.

What it adds

• /fiefs (alias /fi). With no arguments it shows the plugin's version and a pointer to help (fiefs.default).
• /fi help: paged list of commands (fiefs.help).
• /fi list: list the fiefs in your faction (fiefs.list).
• /fi create: create a fief (fiefs.create).
• /fi disband: disband your fief (fiefs.disband).
• /fi claim / /fi unclaim: claim or unclaim the chunk you are standing in for your fief (fiefs.claim, fiefs.unclaim).
• /fi checkclaim: see which fief owns the current chunk (fiefs.checkclaim).
• /fi info: show details of your fief or another fief in your faction (fiefs.info).
• /fi invite, /fi join, /fi leave: manage fief membership (fiefs.invite, fiefs.join, fiefs.leave).
• /fi members: list a fief's members (fiefs.members).
• /fi desc: set the fief description, given in double quotes (fiefs.desc).
• /fi kick: remove a member (fiefs.kick).
• /fi transfer: hand ownership to another member (fiefs.transfer).
• /fi rename: rename a fief (fiefs.rename).
• /fi flags: view and set fief flags (fiefs.flags).
• /fi whois: find out which fief a player belongs to (fiefs.whois).
• /fi config: view and change plugin settings in game (fiefs.config, op only).
• All permissions except fiefs.config are granted to every player by default.
• Config (plugins/Fiefs/config.yml): on first run the plugin writes debugMode, limitLand and enableTerritoryAlerts here, along with its version.
• Usage reporting (on by default): usage-reporting.enabled, usage-reporting.endpoint and usage-reporting.key. When the plugin enables, and each time one of its commands is used, it sends the plugin name, the plugin version or the command name to https://trace.danielstephenson.dev. Nothing about players or the server is sent. Sending happens off the main thread. Every startup logs whether reporting is on.
  • To turn it off for Fiefs, set usage-reporting.enabled: false or run /fi config set usage-reporting.enabled false.
  • To turn it off for every plugin that reports to trace, set enabled: false in plugins/trace/config.yml.
  • Setting either environment variable TRACE_USAGE_REPORTING=off or DO_NOT_TRACK=1 also turns it off.
• The plugin also sends bStats metrics (plugin ID 12743). This follows your server's normal bStats settings.

What it writes

• plugins/Fiefs/config.yml: the settings above.
• plugins/Fiefs/fiefs.json: fiefs, their members, descriptions and flags.
• plugins/Fiefs/claimedChunks.json: chunks claimed by fiefs.
• Data is saved automatically on a schedule and when the server shuts down. If either data file can't be read at startup, the plugin treats the load as failed and won't save over the file.
• plugins/trace/config.yml: the server-wide usage-reporting switch. It is created only if no other plugin that reports to trace has created it already.

Requirements

• A Bukkit/Spigot server supporting API version 1.13 or newer (api-version: 1.13).
• Medieval Factions (hard dependency). This release is built against Medieval Factions 5.7.2. If Medieval Factions isn't available, Fiefs logs that it can't enable and does nothing else.

Since the last prerelease

• Usage events are now reported to trace off the main thread, and the plugin has a per-plugin opt-out (#183).
• Every startup now says whether usage reporting is on. A server-wide opt-out was added in plugins/trace/config.yml. Existing configs get the usage-reporting block written to disk so the switch is visible (#185).
• Fiefs now looks up Medieval Factions when the plugin enables rather than when it is first loaded. This fixes cases where Medieval Factions wasn't found (#190).

Snapshot release marking Fiefs's move to an AI-first development approach.

Day-to-day feature work, grooming, review and maintenance now run through AI agents working directly against this repository, with the maintainers setting direction and approving what lands. The version bump marks that change in how the project is built — it is not a compatibility break. Behaviour, configuration and stored data are unchanged, and existing installations can upgrade in place.

This is a dated snapshot, not a finished release. It follows the precedent set by Medieval Factions' 6.0.0-SNAPSHOT-7-25-2026: the AI-first line has not yet been verified in live operation, and the snapshot designation stays until it has.

Version changes

• pom.xml: 0.11.0-SNAPSHOT → 0.12.0-SNAPSHOT-8-8-2026
