+  **Hellion Chat 0.3.0 — Audit hardening, brand sweep and rebrand of slash commands**
+
+  This release closes the remaining audit follow-ups from the
+  0.2.0 cleanup and finishes turning Hellion Chat into a properly
+  branded fork rather than a Chat 2 with a different name.
+
+  Slash commands have been renamed across the board so they no
+  longer collide with the upstream plugin and tell you which
+  plugin owns them at a glance:
+
+  - /chat2          becomes /hellion
+  - /chat2Viewer    becomes /hellionView
+  - /clearlog2      becomes /clearhellion
+  - /chat2Debugger  becomes /hellionDebugger (internal)
+  - /chat2SeString  becomes /hellionSeString (internal)
+
+  This is a breaking change for anyone with macros bound to the
+  old command names. The upstream Chat 2 commands keep working
+  if you also have that plugin installed.
+
+  Privacy and storage hardening based on the post-0.2.0 audit:
+
+  - Privacy filter master switch now states explicitly that the
+    filter only governs storage, not the live chat log
+  - Emote cache refuses to write outside its own directory if a
+    third-party API ever returns a path that escapes
+  - Retention sweep is serialised so the 24h auto-sweep and the
+    manual button cannot launch in parallel and race for the
+    SQLite connection
+  - DbViewer paging uses an int constant and the matching SQL
+    parameter name (the upstream code passed a float and a name
+    without the parameter prefix; both worked in practice but
+    were inconsistent)
+
+  Visual identity now matches the Hellion Online Media website:
+
+  - Theme palette switched to Arctic Cyan plus Ember Orange,
+    matching the website's BRANDING.md tokens
+  - Active tabs and window title bars use a brand-color-dark teal
+    variation as identity colour, replacing the previous slate
+    violet that did not appear in the brand
+  - Resize grips and scrollbar grabs picked up Ember Orange
+    instead of industrial amber on hover and active states
+
+  About tab rewritten and properly localised:
+
+  - New "Why this fork exists" block sets out the mission in
+    neutral terms, framing Chat 2's full-history default as the
+    right one for most users while explaining the narrower
+    default footprint this fork chose
+  - All Hellion-specific About copy now lives in HellionStrings
+    in EN and DE, so German users see the Hellion sections in
+    German rather than the upstream English fallback
+  - Webinterface absence is described as a focus mismatch
+    (different use case, substantial rebuild) rather than as
+    a security issue with the upstream code
+  - Translator list at the bottom of the About tab is reachable
+    again on smaller settings windows
+
+  Based on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).

By default only your own\nconversations are stored; messages from strangers, NPCs and system\nspam stay out of the database. Retention windows are configurable per\nchannel, history can be wiped retroactively, and stored data can be\nexported on demand.\n\nKey additions on top of Chat 2:\n\n- Channel whitelist with a Privacy-First default\n- Per-channel retention with a daily background sweep\n- Retroactive cleanup with a Ctrl+Shift confirm\n- Export to Markdown, JSON or CSV\n- First-run wizard with three preset profiles (Privacy-First, Casual,\n  Full History)\n- Bilingual UI (English and German) with live language switching\n- Independent plugin state — own config file and database directory,\n  so Hellion Chat does not share state with the upstream plugin\n\nBased on Chat 2 by Infi and Anna, licensed under EUPL-1.2.",
