Version 3.18.6

← Back to the Main Changelog

August 10, 2026

Summary​

This is a large translation-quality release. Free and self-hosted servers can now translate Russian and Ukrainian typed on a Latin keyboard (translit), fancy “icon” letter styles are cleaned up before translation, Greek routing is more reliable, and Discord message protection is much safer around emojis, mentions, URLs, and pings.

Changelog​

What is New​

  • Free / self-hosted translation understands Russian and Ukrainian written with Latin letters (examples: privet, spasibo, kak dela, and many common chat variants).
  • Fancy Unicode letterforms (fullwidth, circled, math bold/italic, small caps, squared letters, and similar) are normalized into real text so they can be translated instead of ignored.
  • Greek conversation pairs prefer CPU LibreTranslate engines to reduce GPU out-of-memory failures.
  • Guild ErrorLog now surfaces missing webhook permission problems so servers can see why mirrors/conversations silently fail.

Improvements​

  • Stronger protection and restore for Discord content: custom emoji, mentions, angle-bracket URLs, code, and related placeholders are less likely to leak or break mid-translation.
  • Ping allowlists and @everyone / @here edge cases are handled more carefully during HTML translation.
  • Context-menu command descriptions are cleared correctly on guild deploy / join deploy.
  • OpenAI GPT-5 reasoning models are supported for BYOK, without silently falling back to machine translation.
  • Write-gate / shard tooling improvements, including higher Discord write pool capacity and guild drill-down support for staff ops.
  • Discord changelog webhook posts no longer ping the whole server (allowed_mentions disabled + mention tokens neutralized).

Fixes​

  • Greek text is no longer treated as “nothing to translate” because of emoji/mention stripping bugs.
  • Symbol-only API translate inputs pass through cleanly instead of causing noisy failures.
  • Command deployment queue processing runs on the sharding manager only (avoids duplicate/racy deploys).
  • Single-shard broadcastEval API payloads parse correctly for guild admin routes.
  • Owner-only commands are no longer registered at normal bot startup.
  • Traditional Chinese (zh-Hant) protection and stash collision edge cases are fixed.
  • Split ping / duplicate mention issues after protection restore are cleaned up.

For Server Admins​

  • No config change is required for the translit and fancy-letter improvements — they apply automatically on free/self-hosted paths.
  • If conversation mirrors were silently dropping, check ErrorLog for webhook permission warnings and grant Manage Webhooks where needed.
  • Discord release announcements from HephBot CI will no longer mass-ping your community.
