Event Tickets with Ticket Scanner

3.0.1 – 2026-04-07

• Improvement: Updated all translations — regenerated POT from source, added 188 new strings, all 11 languages at 100% (de, es, fr, hu, it, ja, nl, pt_BR, pt_PT, zh_CN)
• Improvement: Premium plugin labels (Ticket Template, Excluded Days, License Key etc.) now included in translations

3.0.0 – 2026-03-31

• Fix: Admin CSS was cached by Cloudflare/browsers after plugin updates — added version-based cache buster to dynamically loaded stylesheet
• Fix: Scoped global CSS button selectors to plugin container — no longer affects WP admin sidebar
• Fix: Backend CSS now loaded via wp_enqueue_style instead of JS injection (prevents layout shift)
• Fix: Removed duplicate Settings submenu entry (top-level menu only)
• New: QR code scanner on the validator form — users can scan QR codes with their device camera instead of typing codes manually (enable in plugin settings)
• New: License key prompt dialog on settings page instead of browser alert — with direct link to options page
• Fix: Ticket table button column no longer forces minimum width (cleaner layout on small screens)

2.9.9 – 2026-03-23

• Improvement: License check resilience — brief server outages no longer disable premium features; raised failure threshold from 5 to 10, extended staleness window from 10 to 21 days, and server errors (5xx, empty body) now count as transient failures instead of genuine rejections
• Fix: “Check License” button now resets failure counter before server check — previously, accumulated failures from a server outage could prevent recovery even after the server was back online
• Improvement: Modern admin UI redesign — card-based layout with consistent spacing, branded purple accent color, professional footer grid, improved DataTable styling, smooth loading animations, and responsive design
• New: Plugin header now includes Requires at least, Tested up to, and Requires PHP — displayed in support info area for easier troubleshooting
• Fix: Corrected 10 English typos in source strings that caused translation mismatches (e.g. successfull, duplicat, choosen)
• Fix: No more flash of unstyled content when loading admin page
• Improvement: Regenerated all German backend translations — from 162 to 451 strings (full coverage)
• New: FOMO banner for expired premium subscriptions — shows new features released since expiration with dismissible 30-day reminder
• Fix: Added missing License header to plugin file to satisfy WordPress.org plugin check

2.9.8 – 2026-03-11

• Fix: TypeError in WooCommerce email preview and order emails — removed strict type hints from all WooCommerce hook callbacks to prevent crashes with different WC versions

2.9.7 – 2026-03-11

• Fix: Options migration safety net — premium options (e.g. PDF ticket attachment) are now preserved even if the premium plugin was inactive during the database migration from wp_options to the custom options table

2.9.6 – 2026-03-10

• New: Daily Redemption Summary — view redeemed tickets across all products for any date range (Premium)
• New: No-Show count in Attendance view showing unredeemed tickets per event (Premium)
• New: Drill-down from Attendance rows to individual ticket codes with order links (Premium)
• New: Export Attendance data as CSV (Premium)
• Improvement: Seating CSV export/import now includes visual designer data — position, rotation, shape, and color survive roundtrip (Premium) (#209)
• Fix: Seating CSV export appended JSON artifact at end of file — missing exit after CSV output (#209)
• New: Calendar view and printable ticket list on product edit page for daychooser products (#191)
• Performance: Lazy-load single options via getOption() instead of bulk-loading all options
• New: License Server Connectivity Check — diagnostic button in Support area tests if vollstart.com license/update server is reachable. Shows connection status, response time, and detailed error messages. Helps diagnose Premium update issues caused by firewalls, DNS problems, or network restrictions.
• Improvement: Subscription expiration warnings now distinguish between license types — lifetime/onetime licenses show no warning (continue working with Basic < 2.8.0), monthly subscriptions warn about payment processing, yearly subscriptions warn about expiration.
• Improvement: Renamed “Serial Key” to “License Key” in all user-facing strings for clarity
• Improvement: Complete translations for all 11 languages (DE, ES, FR, HU, IT, JA, NL, PT_BR, PT_PT, ZH_CN, DE_CH) — 100% coverage

2.9.5 – 2026-03-03

• Fix: Premium serial key displayed as 0 after options migration — premium features appeared lost. Options added late during initialization (e.g. by the premium plugin) are now loaded correctly from the custom table.

2.9.4 – 2026-03-03

• Performance: Plugin options migrated from individual wp_options rows to a dedicated custom table — all settings now load in a single query instead of 150+ separate queries (#73)
• New: Options change history — tracks who changed which setting, when, with old and new values. Revert button to restore previous values. Keeps last 10 entries per option, older entries cleaned up automatically. Available in Options > Change History tab (#73)
• New: Context-Wizards — smart suggestions on the options page based on your current configuration. Detects related settings and offers to enable them with one click. Covers email attachments, scanner presets, ticket display, and security settings. Dismissals are per-user (#232)
• New: Export and import seating plan seats via CSV for backup, external editing, or transfer between plans (Premium) (#209)
• Fix: Old premium plugin (< 1.6.0 or without version constant) caused crash instead of being gracefully blocked
• Fix: Options migration is now abort-safe — if interrupted, it resumes on next page load instead of silently losing settings. Existing values are updated correctly on re-run.
• Fix: Database upgrade jobs now run before saving the new DB version, preventing incomplete upgrades from being marked as finished
• Fix: Premium or third-party upgrade hooks that throw exceptions are now caught and logged instead of causing an infinite crash loop
• Security: Activate global ticket counter brake to prevent free limit bypass via delete-and-recreate

2.9.3 – 2026-03-02

• New: “Check License” button — recheck premium license status on demand from Options page (next to serial field) and Support Info page. Shows status, last check, expiration, failure count.
• Improvement: Saving a serial key now immediately checks the license and shows the result inline. On success, the page reloads automatically so premium features are available without manual refresh.
• Improvement: “Check License Now” button bypasses the 7-day server cache to always get a fresh response
• Fix: Dismiss button for ticket format warnings did not work — two bugs: nonce parameter name mismatch, and wp_redirect() called during admin_notices (after output started). Dismiss handler now runs on admin_init.
• Fix: JavaScript error “cannot call methods on dialog prior to initialization” — closeDialog() tried to destroy all dialog elements on page instead of only the target dialog
• Fix: backend.js could be cached by browser across updates — jQuery.getScript() bypassed WordPress cache busting. Now uses file modification time as additional cache-buster parameter.
• New: Setup Wizard — multi-step dialog guides new users through use-case selection (Event tickets, Day passes, Memberships, Vouchers) and configures optimal settings automatically. Covers redemption rules, scanner behavior, email delivery (ICS, date, order view), and order processing. Premium users also get PDF attachment settings. Re-launchable via “Start Wizard” button.
• New: Premium Wizard — one-time dialog when premium is activated, offers to enable recommended premium defaults (PDF email attachment, merge into one PDF). Re-launchable via “Premium Wizard” button (only visible with premium). (#233)
• New: Export/Import options — backup and restore all plugin settings as JSON file
• New: “Max redeems per day” option per product — limit how many times a multi-redeem ticket can be redeemed on a single day (0 = unlimited, only total max applies)
• Improvement: “First Steps” onboarding box upgraded to interactive card with progress bar, auto-detection of completed steps, and action buttons
• Improvement: Code generation now uses date-based prefix (encoded as 5 letters) to partition address space — virtually eliminates collisions even with short code formats
• Improvement: Increased code generation retry limit from 100 to 500 attempts
• Improvement: Ticket detail view now shows WooCommerce order status, billing email, product name, and variation attributes
• Improvement: Support Info — options list is now hidden behind a button click to reduce page load clutter
• Improvement: Bulk action dropdown now shows a message when no tickets are selected
• Improvement: AJAX calls now properly handle network-level errors (timeout, connection lost)
• Improvement: Cart input fields (name per ticket, restriction code) now auto-save on Enter key (#234)
• New: Auto-update dialog — after entering a serial key with an outdated premium plugin, automatically checks for updates and offers to install them. Shows release notes for users without an active subscription.
• Fix: Value-per-ticket dropdown in cart never saved — selector targeted wrong element type and attribute (#234)
• Fix: Options in-memory cache corruption in _setOptionValuesByKey() — variable name collision caused stale/incorrect values within the same request
• Fix: Restriction code input in cart crashed on PHP 8.x due to wrong constant name case (META_KEY_CODELIST_RESTRICTION_order_item → _ORDER_ITEM)
• Fix: False “Ticket format exhausted” warning when free version ticket limit (32) was reached — #208 exception was incorrectly triggering format warning on first attempt
• Fix: clearFormatWarning() never actually cleared warnings — editList() was called with wrong signature, exception silently caught
• Fix: “Edit list” link in format warning notice and email pointed to non-existent admin page
• Fix: Import options failed silently due to WordPress wp_magic_quotes escaping JSON — now handled via stripslashes
• Fix: Product meta save could trigger PHP warning for undefined array key due to operator precedence bug
• Fix: Admin ping timeout (e.g. when browser tab is frozen) no longer shows repeated error dialogs
• Fix: Typo in displayFirstStepsHelp option description (“activet” → “activated”)

2.9.2 – 2026-02-23

• Fix: Format warning data (attempts, last_email) was never persisted — editList() called with wrong signature and would auto-clear warnings

2.9.1 – 2026-02-23

• Fix: Crash during checkout when format warning check runs (undefined method _json_encode_with_error_handling)

2.9.0 – 2026-02-23

• Fix: Crash on PHP 8.x when plugin loading order puts basic before premium (e.g. after auto-update) — now defers premium loading via plugins_loaded hook
• Fix: Crash in get_expiration() on PHP 8.x when license data contains invalid JSON
• New: Old premium versions (< 1.6.0) are now gracefully blocked instead of causing fatal errors — site runs as free with admin warning
• New: Serial key field shown in basic plugin settings when old premium is detected, so users can still manage their license
• Improvement: License check now properly throttles retries when serial key is invalid, preventing excessive server calls
• Improvement: Changing the serial key now immediately triggers a fresh license check instead of waiting for the next cycle
• Fix: Invalid serial key no longer causes license check on every page load
• Fix: All non-German translations (NL, ES, IT, PT_BR, PT_PT, HU, JA, ZH_CN) replaced with proper localized translations — previously contained German text
• Fix: Renewal and reactivation links in admin notices pointed to wrong URL
• Fix: Ticket redemption blocking (“deny redeem before event start”) was off by the GMT offset for non-UTC timezones

2.8.10 – 2026-02-18
