Version: 2026-08-19 — v1.1.1 FIX: the internal VERSION constant was still hardcoded to 1.0.1 after the 1.1.0 release, so the admin header badge, the About tab, and the Google Safe Browsing clientVersion field kept reporting the wrong version. Now matches the plugin header (1.1.1). Version: 2026-08-14 — v1.1.0 COMPAT: WordPress 7.1 confirmed — reviewed the iframed post editor, client-side media processing, @wordpress/components changes, persistent toolbar, and jQuery UI 1.14.2 update; none of these affect this plugin (no editor, media, toolbar, or jQuery UI hooks used). NEW: SSL certificate details in the WHOIS/DNS modal — issuer, TLS protocol version (best-effort probe), and Subject Alternative Names (SANs) now shown alongside the existing SSL expiry date. Version: 2026-07-15 — v1.0.1 COMPAT: WordPress 7.0.1 confirmed — reviewed the 7.0.1 patch file list; no changes affect admin_post, wp_ajax, admin_menu, cron, or wp_mail hooks used by this plugin. FIX: Uninstall cleanup — uninstall.php was leaving the lmnsimo_order option (card sort order) behind in wp_options after uninstall; now deleted along with the other plugin options. FIX: Uninstall cleanup — per-site malware scan schedules (lmnsimo_scan_site_cron) were not cleared on uninstall, leaving orphaned cron events; now cleared alongside lmnsimo_check_sites_cron. IMPROVE: Requires at least / Requires PHP added directly to the plugin file header, so WordPress core itself blocks activation on incompatible sites. Version: 2026-05-26 — v1.0.0 COMPAT: WordPress 7.0 full compatibility — tested and confirmed against WP 7.0 core changes (Modern theme, PHPMailer 7.0.2, PHP 7.4 minimum). IMPROVE: CSS scoping fix — postbox header rule (.hndle) now correctly scoped to .lm-scope, preventing style leakage to other dashboard widgets on index.php. NEW: Apache ECharts 5.6.0 + echarts-gl 2.0.8 bundled locally in /assets/ (no external CDN, GDPR-safe); Chart.js replaced as charting engine. NEW: 3D bar chart of response times per site via echarts-gl (WebGL). NEW: GitHub-style activity heatmap (checks per day/hour) powered by ECharts heatmap series. NEW: Toggle in the charts UI to switch between 2D and 3D view. IMPROVE: Dark mode for charts uses ECharts native ‘dark’ theme — no extra CSS required. IMPROVE: Chart.js and date-fns adapter removed from plugin bundle; replaced by ECharts 5.6.0 (self-hosted, Apache 2.0 licence). Version: 2026-05-16 — v0.9.4 NEW: Site thumbnail — each card now shows a screenshot preview via Automattic mshots (s0.wordpress.com/mshots/v1/). No API key required; images load lazily with CDN caching and dark-mode brightness filter. NEW: Telegram Bot alerts — new accordion in Settings → Alerts: Bot Token + Chat ID. Formatted HTML messages sent for all alert types (site down, recovery, SSL expiry, domain expiry). Works alongside email and Discord. NEW: Discord Webhook alerts — new accordion in Settings → Alerts: Webhook URL. Alerts delivered as color-coded embeds (red = down, orange = warning, green = recovery). SECURITY: Full secrets encryption — SMTP password, Telegram token, Discord URL, Google Safe Browsing key, and URLhaus key are encrypted with AES-256-CBC using AUTH_KEY + SECURE_AUTH_SALT before storage. Settings forms never return secret values to the browser. IMPROVE: i18n complete — 51 previously untranslated PHP strings added to the .pot template and fully translated across all 16 supported languages; all .po and .mo files recompiled. A pre-existing untranslated string (Google Safe Browsing optional key notice) also filled in for 7 languages. FIX: Closing the security scan modal no longer causes a flash from dark to light mode; page reload removed, scan results update in-place. FIX: Scan status label (“No incidents” / “Incidents detected”) now appears on the card immediately after scanning, without requiring a manual page reload. FIX: Plural-form translations in .mo files were corrupted (drag-to-reorder label was appearing in SSL/domain expiry day fields); all 16 .mo files recompiled with correct GNU gettext plural-form encoding. IMPROVE: Performance charts redesign — neon color palette for bar chart; trend chart shows filled min–max band with adaptive Y axis; distribution chart replaced with animated Polar Area chart; neon glow effect on all chart canvases in dark mode. Version: 2026-04-29 — v0.9.3 NEW: Animated toast notification system — success / error / warning toasts appear bottom-right, auto-dismiss 3.8 s, click to close, slide-in/out animation. Replaces silent AJAX operations. IMPROVE: “Force” and “Check all now” buttons change to “Checking…” and disable during server-side check. IMPROVE: Pin/Unpin actions show a success toast; AJAX errors show an error toast with UI rollback. IMPROVE: Card reorder now shows “Order saved” toast on server confirmation. IMPROVE: Site cards lift 2 px on hover with smooth shadow transition; suppressed during drag. IMPROVE: 5 new i18n strings added; translations for 16 languages pending. SECURITY: SSRF protection — admin-supplied URLs validated against private/reserved IP ranges before acceptance; only http/https allowed. SECURITY: error_msg sanitization — HTTP error body snippets sanitized with sanitize_text_field() before storage. NEW: Unified action bar (top + bottom) — Select all checkbox, bulk actions, Check all now, Scan all, Export CSV, Import CSV consolidated in one strip above and below the cards. NEW: Scan all — sequential background scan of all monitored sites with live badge updates and completion toast. IMPROVE: 3 new i18n strings (selectAll, scanAll, scanAllDone) translated in 16 languages. Version: 2026-04-02 — v0.9.2 FIX: URLhaus (abuse.ch) integration now requires an API key (Auth-Key header); added URLhaus API Key field in Settings → Security scanning. Without a key the URLhaus check is skipped gracefully. FIX: Scan modal failed to open with “i18n is not defined” JS error — resolved by declaring i18n from cfg.i18n inside initScanModal(). FIX: PDF security report printed blank — modal is now temporarily moved to document.body before window.print() and restored afterwards so @media print selectors work correctly. FIX: “Scanning…” text rendered as garbled bytes (double-encoded UTF-8) — replaced with an animated indeterminate progress bar. IMPROVE: Scan badge button removed from card header; scan result (shield icon + date + status label) now appears as an inline row inside the card metadata block, consistent with the rest of the card layout. FIX: “Scan” button font-size reduced to match the rest of the card action buttons (11 px). IMPROVE: Status labels renamed to “No incidents” / “Incidents detected” (es_ES: “Sin incidencias” / “Incidencias detectadas”), color-coded green and red respectively; all 16 .po/.mo files updated. NEW: Help tab with 12 documented sections covering all plugin features: Getting started, Uptime monitoring, SSL & domain expiry, Email alerts, Performance charts & statistics, Malware scanning, WHOIS / DNS lookup, Dashboard widget, CSV export / import, Card management, and step-by-step guides for both API keys (Google Safe Browsing and URLhaus). IMPROVE: Top toolbar now shows a compact API keys notice with direct links to Google Cloud Console and abuse.ch, replacing the old generic description block. IMPROVE: 21 new i18n strings added to all 16 supported languages. Version: 2026-03-25 — v0.9.1 NEW: Malware scanning powered by Google Safe Browsing API (free key required) and URLhaus (abuse.ch, no key required). Scan button on each site card opens a security report modal. NEW: Per-site automatic scan schedule (Never / Daily / Weekly) with WP Cron integration.

Version: 2026-03-16 — v0.9.1 NEW: Performance charts (bar, line, donut) powered by self-hosted Chart.js 4.5.1 (GDPR-safe, no external CDN). NEW: Response-time history stored in a dedicated database table (lmnsimo_response_log); rolling 500-entry window per site; table removed cleanly on uninstall.

User Notifications lets you seamlessly inform WordPress & WooCommerce users about updates, sales, and more via the site navigation menu. You can add a notification menu easily by using the [notifications_dogbytemarketing] shortcode to inject a notification bell into your menu. The bell displays a badge when new notifications are available, ensuring users never miss an update. If you use something other than BootStrap icons, you can do [notifications_dogbytemarketing class=”your-icon-class”] to use your own icons. You can also use the “class_container” attribute to add additional classes to the notification-container element. This plugin is ideal for websites and WooCommerce stores looking to improve user engagement and streamline notification delivery. Features Supports WooCommerce Send notifications when a WooCommerce order is completed (shipped) Custom post type for creating and managing notifications.
