1.51: 26.2 Support

Hi all,

We've added 26.2 support in this release.

Have a great summer!

WorldwideChat v1.50: Redesigned for 26.1, Add Guardrails, New AI Options

Hello!
This is a major release focused on backend stability, AI reliability, and user-facing translation experience improvements.

Changes:

1. Added guardrail support for all AI providers. Essentially a 'guardrail' prompt will run before each request with your arbitrary rules. This model can be set to be separate from the main one.
2. Added OpenAI-compatible provider support alongside existing ChatGPT and Ollama paths. This is a third AI option meant for services such as vLLM/OpenRouter.
3. Enabled OpenAI Responses API defaults:
   • Endpoint: https://api.openai.com/v1/responses
   • Default ChatGPT model: gpt-5.3-chat-latest
4. Added optional Guidelines AI checks with configurable prompts and model selection.
5. Added the new loading/translation indicator experience (action bar based progress instead of chat, smoother spinner flow).
6. Added Paper Dialog API input support with configurable General.inputMethod:
   • auto
   • paper-dialog
   • conversation
   • none
7. Added translation controls for capacity and object throughput for better performance:
   • General.translationCapacityLimit
   • General.objectTranslationConcurrencyLimit
8. Added clearer feedback from translation failures and make them less vague.
9. Much better concurrency support for entity/world translation (meaning faster responses with sign/book translation.)
10. Expanded migration + status checks for SQL and MongoDB cleanup/deduplication and lookup performance.
11. Bumped runtime baseline to Java 21 and plugin compatibility docs to Spigot/Paper/Folia 1.20+. 1.19 and below are no longer supported.
12. Fixed bugs across /wwct stop, /wwcg, /wwcs, rate limiting, folia scheduling issues, and more
13. New testing server :)

As always take care!

Technical Notes (for those inclined, see per-commit for more details.)

• Added migration engine wiring:

  • StorageMigrationUtils and migration status model
  • Flyway-backed SQL/PostgreSQL migration path
  • Mongock-backed MongoDB migration path
  • New normalization migration for cache dedupe/index/key consistency
  • Migration failure handling disables plugin on unsafe state rather than continuing partial startup

• AI/prompt pipeline changes:

  • OpenAI-compatible API support (URL/API key/model/prompt integration)
  • Shared guardrail/prompt templates across providers
  • Better OpenAI response parsing for both strict JSON and failure paths
  • Optional Guidelines AI is now explicit and configurable instead of implicit behavior

• Input/interaction refactor:

  • Input abstraction for conversations/paper dialogs/null-input modes
  • General.inputMethod selection exposed in config + GUI paths
  • Paper dialog availability checks by version/classpath plus fallback strategy

• Loading/progress revamp details:

  • Action bar indicator now behaves as a proper lifecycle:
    • delayed start display
    • pulsing frame updates while active
    • safe clear path on completion
    • hard timeout guard and explicit error state behavior
  • Separate handling for object translation UX so long-running object workflows don’t stall or spam chat output

• Throughput and concurrency:

  • Added bounded translation capacity + object concurrency controls
  • Broader race-condition and queue fixes in translation/test flows
  • Threading and scheduler behavior improved for async/folia-safe execution paths

• Storage and startup:

  • Cache loading and sync logic tightened across YAML/SQL/Postgres/Mongo
  • Better startup task orchestration during reload to reduce partial-init races
  • More deterministic plugin bootstrap and background task cancellation/restart behavior

• Maintenance + hygiene:

  • Large dependency refresh across modules
  • GitHub workflow security/CI adjustments
  • Expanded test coverage for migration paths and platform-specific scheduler/performance scenarios

Full Changelog: v1.20.1...v1.20.2

Hello! This is a minor update that fixes some mission-critical bugs:

• Fixes listeners leaking memory by not being unregistered after /wwcr.

Take care

WorldwideChat v1.20.0: 1.21.4 Support, Citizens Support, DecentHolograms Support

Hello! This update fixes 1.21.4 support and adds some requested features:

• Sounds were completely broken on 1.21.4. This has been resolved and sounds no longer have the ability to break this plugin.
• Add Citizens support. If an NPC has dialogue that is periodically sent, you have /wwct turned on, AND you have entity translation enabled, then all messages from these local NPCs will be automatically translated.
• Add DecentHolograms support. Simply right-click on an active hologram to translate it (like you would a sign) after toggling sign translation. The result will be sent to your chat.
• If your Minecraft version is unrecognized, we will default to the latest supported version instead of 1.13 for features.
• Fix several bugs in our commands. See the commit history for specifics.
• Revamped our test suite + bumped dependencies, significant refactoring done internally.

Have a great 2025!
Full Changelog: v1.19.2...v1.20.0

WorldwideChat v1.19.2: Fix Visual Translate Bugs, Add More Sounds

Hello! We have an additional minor update for WorldwideChat. It fixes some important visual/underlying bugs:

• Added new sounds for menus like /wwcs and /wwc.
• Properly handle "auto" translation (previously could cause potential issues)
• Fix inconsistent sign/book translation handling implemented in previous update
• Fix inconsistent REDACTED text in /wwcc
• Fix poorly designed language name displays in /translate
• Fix some bugs where the plugin could raise an exception in 1.13.2
• Bump dependencies

We also now have a youtube tutorial! Check it out: https://www.youtube.com/watch?v=vXl9KDFdPLQ&t=814s

Full Changelog: v1.19.1...v1.19.2

WorldwideChat v1.19.1: Add Sounds, Fix Rate Limit Bugs, Revamp Appearance

Hello! We're pushing one more minor release for WorldwideChat alongside a tutorial video (will be uploaded shortly).

It includes the following changes:

• Sound effects! /wwct, /wwcr, and /wwcl now include sound effects that attempt to not be intrusive. If you'd like to disable them, just set General.enableSounds to false in the main config.
• Better handling of language formats. When a translation session starts with /wwct, instead of showing the lang code by default we show the native language if it is present. This is also updated on notifications for when a player re-joins the server.
• Sign/book translation will more accurately reflect when a translation actually fails instead of blindly claiming "success."
• Fixed the rate limit exempt permission not overriding numerical rate limit permissions.
• Sign translations will now be counted as one translation for rate limits rather than 1 for each line.
• Fixed the http:// protocol throwing an exception on Libre/Systran Translate.

Take care!
