+# Changelog
+
+All notable changes to MMM-MessageCenter are documented in this file.
+
+## 0.1.0 - 2026-08-01
+
+### Added
+
+- Normalized message contract with independent urgency and retention.
+- Newest-first in-memory history, expiration, deduplication, and acknowledgement.
+- Individual message acknowledgement and dismissal controls and notifications.
+- Webhook ingestion with optional bearer authentication.
+- Optional MQTT and Unix-domain-socket transports using the same normalized schema.
+- Optional ingestion-time image snapshots with full-page and compact presentation.
+- MagicMirror internal notification ingestion for weather and MMM-Remote-Control.
+- Toasts, semantic attention state, and optional MMM-pages channel routing.
+- Integration-neutral attention-event configuration with compatibility for the
+  former Seymour-named option.
+- Inbox UI with urgency styling, read-state transitions, history controls, and
+  MagicMirror locale and clock-format support.
+- Compact region-friendly presentation for standard MagicMirror layouts.
+- Unit tests, product roadmap, static UI preview, and live-test checklist.
+
+### Security
+
+- Webhook JSON size limits and optional bearer-token enforcement.
+- Explicit allowlisting for MMM-Remote-Control ingestion to avoid operational
+  traffic and recursive MessageCenter events.
+- Image download limits, timeouts, signature checks, bounded redirects, and
+  private-host/unencrypted-HTTP blocking by default.
+- Localhost-only webhook binding by default; LAN access now requires explicit
+  configuration.
+- Rolling image-cache limits preserve the newest 12 snapshots within a 12 MiB
+  decoded-byte budget while retaining older text history.
+- Non-touch presentation can hide all buttons and limit rendered messages
+  without deleting bounded queue history.
