Version history

Fixed

• Installer: the installer rejected its own echoai.sql ("Invalid SQL file") it now accepts the bundled file again
• Installer: a clean install created no EchoAI tables (every "CREATE TABLE IF NOT EXISTS" statement was skipped while the installer still reported success) all tables are created again
• Chat: "## Heading" lines in AI replies showed "$2" instead of the heading text
• Chat: the default AI avatar (fa-star) showed a broken glyph instead of the star icon
• Upgrade window: empty plan list ("No packages available") on sites still set to Sngine packages from an older version

Revamped / Changed

• The installer now shows and records version 1.6.1 (it showed "Version 1.0")
• New download structure: 1-Clean-Install, 2-Updates (from 1.6 and from 1.4 / 1.5) and 3-Documentation
• New full documentation with screenshots (HTML + PDF) included in the download

Migration note: from 1.6, upload EchoAI-Update-1.6.1.zip in Admin → Update (only index.php changes). From 1.4 / 1.5, upload EchoAI-Update-1.6.1-full.zip and merge admin/settings.php manually. No database changes are needed.

Added

• Session verification (includes/session_guard.php): EchoAI now checks the Sngine login session (c_user + xs against users_sessions) before trusting who is logged in
• OpenAI GPT-6 models: GPT-6 Astra, GPT-6 Sol, GPT-6 Luna
• DeepSeek V4.1 Flash (deepseek-flash) DeepSeek V4.1 Pro listed as "Coming soon [Not yet launched]" (not selectable yet)
• New API action get_message_feedback_counts returns like/dislike counts for a whole conversation in one request
• Addons → EchoBot → Settings opens the EchoBot Command Center (for the EchoBot 1.1 add-on)

Fixed

• Security: a forged c_user cookie could open AdminCP and chat as any member every page, API call and admin action now requires a valid Sngine session
• Security: the legacy user_session cookie fallback allowed SQL injection it now accepts only plain token characters
• OpenAI GPT-5.x and GPT-6 requests failed ("max_tokens is not supported", "temperature not supported") all OpenAI calls now send max_completion_tokens and the default temperature for these models, and DeepSeek is unchanged
• Images whose file was deleted from the server returned 404 errors and showed as broken the chat now shows a placeholder without requesting the missing file
• Mobile header overflowed on phones (the Settings gear was pushed off-screen)
• New installs were stamped version 1.3.1 they are now stamped 1.6

Removed

• AdminCP (shield) and Settings (gear) buttons from the top bar on phones (both are in the sidebar menu) desktop is unchanged
• External documentation links from the installer (it now points to the README included in the download)

Revamped / Changed

• Opening a conversation loads all like/dislike counts in one request instead of one per message (about 80 → 1 on long chats)
• Model selection in Admin → Settings → AI Configuration gains GPT-6 (Astra, Sol & Luna) and DeepSeek V4.1 groups
• Import Conversations wording made provider-neutral ("ChatGPT, DeepSeek, or another AI")
• EchoBot settings popup in Addons renamed to "EchoBot — Command Center"

Migration note: admin/settings.php is skipped by the in-app updater, so merge it manually to get the GPT-6 and DeepSeek V4.1 model choices in Admin → Settings. No database changes are needed. includes/config.php needs no edit, because the session check also loads from includes/functions.php.

Added

• Incognito Mode (per-message toggle, not saved to history/memory, one-time warning modal + persistent banner)
• Full PWA support (installable app, manifest.php, service worker, "Install App" row in Settings)
• Firebase Cloud Messaging push notifications (replaces OneSignal)
• 2 new interface languages: Italian, Spanish (Mexico)

Fixed

• Hamburger menu button stuck visible on desktop after resizing up from mobile width
• Admin dark-mode: .dark class was never applied anywhere (only .light-mode existed) — Admin → Update page, Dashboard Quick Actions, and system-status bar were stuck in light-mode colors

Removed

• Decorative "System Update Manager" header card from Admin → Update
• OneSignal notification integration (replaced by Firebase)

Revamped / Changed

• Memory → Backup now downloads the .json file immediately (previously just showed a toast)
• Data & Storage tab reorganized into Behavior / Data / Danger Zone sections with clearer labels
• Visual pass: Incognito modal uses real Font Awesome icons (was emoji), Settings sidebar tabs get accent-colored icon chips + row hover states, chat view gets header shadow, avatar rings, and "tail"-style message bubble corners

Migration note: admin/settings.php is skipped by the in-app updater — merge it manually to get the Firebase and Incognito admin fields on your live site.

New Features

• Scope Restriction — confine the assistant to specific allowed topics using a real AI classification call
• Hero / Unit Combos — ground gaming-community tactical questions in admin-curated pairing data instead of AI guesses
• Troop / Unit Calculator — exact, server-computed resource training/upgrade answers for gaming communities, never left to the AI to calculate
• Time-zone conversion — EchoAI now actually uses each user's detected browser time zone to answer "what time is X for me" questions with a real computed time, instead of leaving it unused

Fixed

• The Sngine Site URL setting being hardcoded at install time with no way to change it afterward except direct database access — it now has its own editable field in Admin → Settings
• A bug with conversation's Pin/Edit/Delete controls in the chat sidebar staying stuck open instead of only appearing on hover or via a small dedicated button

Revamped

• Library Modal — redesigned with pill-style tabs, refined card styling, and clearer empty states
