Upgrading from 1.12 - nothing to change. Your config.yml is kept as it is, gate-dial-spin included, so gates dial with the ring light they had. One permission changes: a rank holding wormhole.build.* without wormhole.build built nothing before and now builds every shape (first bullet). The new max-gates-per-player is appended at 0, no limit, the first time it loads. Captures move to data/captures/ by themselves the first time they are needed. From 1.10 or earlier, read the 1.11.0 upgrade note below first: an unedited config.yml is replaced there, and gets the new gate-dial-spin: none. A first install needs none of this.

• Build permission per shape: wormhole.build.<shape> lets a rank build one gate shape, its name in lower case with anything but a letter, digit or underscore made an underscore (wormhole.build.standard); wormhole.build still allows every shape. A rank given wormhole.build.* now builds every shape.
• A gate limit per player: max-gates-per-player caps the gates one player may own, off at 0; wormhole.gates.max.<n> gives a group its own limit, wormhole.gates.unlimited lifts it, and /wormhole gate list shows a limited player their count and limit.
• A use cost per gate or shape: /wormhole gate edit <gate> cost <amount> gives one gate its own cost and USE_COST=<amount> in a shape file gives every gate of that shape one; default clears a gate's own, so it follows its shape and then economy-use-cost.
• A view level per gate: /wormhole gate edit <gate> view <horizon|behind|open|default> wins over gate-view, and /wormhole mirror debug <gate> says how a gate's view is drawn and, if it is not, why.
• No ring light by default: gate-dial-spin now defaults to none, as the original plugin dialled; /wormhole config gate-dial-spin top brings back the 1.12 default.
• Captures move to data/captures/, gates/ and mirrors/, so data/gates/ holds gate files only. A script reading the old capture folders must look in the new ones.
• Gate views: gate-view: behind leaves a gate with a lava or opaque horizon as it is, and a gate's view is retaken only from chunks that are loaded, so the retake no longer loads or generates chunks.
• bStats counts gate frame blocks: a new gate_material pie sends the game's own block name, never a name a server chose; metrics-enabled: false stops it with the rest.
• Fixes: /wormhole complete and /wormhole gate build without net= use the Public network instead of refusing a builder holding only wormhole.build, a sign gate dials the gate its sign shows after a restart or /wormhole refresh, and a window no longer leaves creatures hidden when the server refuses to hide one.
• Internals: the window drawing, gates and build previews were reorganised into smaller classes; nothing a player or admin sees changes.
