1.1.1.19

Fixed an issue where logged-out visitors could be redirected to an empty basket during WooCommerce-backed event booking flows.
Improved WooCommerce guest session handling for event registration and meal booking.
Added protection for dynamic calendar parameter URLs to reduce crawler-driven server load.
Added noindex/canonical handling for parameter-based calendar views.
Added validation for invalid or extreme calendar date requests.

1.1.1.18

Multi-ticket cart fully functional in Lite: The free RSVP handler in class-pcal-rsvp-form.php now loops over every ticket type in the submitted cart and registers an attendee for each one. Earlier Lite builds only registered the first ticket type (via array_key_first()) and silently discarded the rest, pushing users to upgrade for multi-ticket support. That behaviour violated WP.org guideline 5 (no functionality locked behind a paid upgrade) and has been removed entirely. Lite now supports as many ticket types per registration as the event admin has created.
Output escaping: Replaced the remaining phpcs:ignore escape-output annotations in class-pcal-shortcodes.php with proper wp_kses() calls using a new pcal_calendar_kses_allowed() allowlist (in helpers.php). The allowlist covers the structural HTML the calendar emits — div, span, table, time, figure, picture, svg, etc. — plus data-* and aria-* attributes used by the front-end JS to hydrate templates. Output-side escaping is now compliant with WP.org's "escape late" rule, no exceptions remain.
Inline style cleanup: Migrated the last inline <style> block (mobile responsive overrides in class-pcal-archive-list.php) from a direct echo '<style>' call to wp_add_inline_style() attached to the front-end stylesheet, per WP.org's enqueue requirement.
No DB schema changes; no behavioural change beyond multi-ticket registration now working in Lite.

1.1.1.17

Tickets and Attendees are now fully-functional Lite features per WordPress.org plugin-directory guideline 5 (no locked or hidden features). The post types pcal_ticket and pcal_attendee are admin-visible under Site Calendar in wp-admin. Admins can create tickets for any event (one or more ticket types, each with label, price, capacity, max-per-order, sort order, and an optional description). The Attendees list shows every front-end RSVP registration with name, email, event, ticket type, quantity, status, and registration timestamp.
REST data protection: Venue and Organizer phone/email fields are stripped from public REST responses for unauthenticated callers (logged-in users with edit_posts capability see the full record). Prevents unauthenticated scraping of contact data not otherwise published on the front-end. Affects /wp-json/pcal/v1/events, /events/<id>, /venues, /venues/<id>, /organizers, /organizers/<id>.
Pro-only features: Site Calendar Pro continues to add multi-ticket inline editor on the event page, capacity gauges, automatic confirmation emails, branded HTML email template, refund handling, QR-code door check-in, CSV export of attendees, bulk operations (resend confirmation, send custom email), front-end event submission, recurring events, Week/Day/Photo views, custom fields, and WooCommerce integration.
No DB schema changes; existing tickets and attendees on sites running Pro continue to work without migration.

1.1.1.16

Shortcode prefix update: Following WordPress.org reviewer guidance, the plugin's public shortcodes have been renamed to use the plugin's own prefix:
[getsitecalendar] (replaces [pro_calendar])
[getsitecalendar_list] (replaces [pro_calendar_list])
[getsitecalendar_search] (replaces [pro_calendar_search])
[getsitecalendar_rsvp] (replaces [pro_calendar_rsvp]) The previous shortcode names are kept registered as silent backward-compatibility aliases, so existing customer sites continue to render correctly without any action required. New documentation and the in-plugin Help tab now use the new names.
Plugin Check compliance: Final cleanup pass addressing the remaining 15 Plugin Check warnings from 1.1.1.15.
Removed the load_plugin_textdomain() call from class-pcal-plugin.php. WordPress.org auto-loads translations for hosted plugins since WP 4.6, so the manual call is discouraged and unnecessary.
Prefixed global variables in uninstall.php ($post_types → $pcal_post_types, etc.).
Added phpcs:ignore annotations with justifications for the legitimate uses of the WordPress core the_content filter in REST responses (processes shortcodes/oEmbeds, matching standard WP behaviour).
Added phpcs:disable annotations with justifications for WordPress cache plugin standard constants (DONOTCACHEPAGE, DONOTCACHEOBJECT, DONOTCACHEDB) in class-pcal-archive-list.php to match what we already did in class-pcal-month-grid.php and class-pcal-rsvp-form.php.
Added phpcs:ignore annotation with justification for the one direct database query in uninstall.php that finds and deletes every plugin record across the site (caching is meaningless for a one-shot uninstall operation).
Trimmed Upgrade Notice entries to fit the 300-character limit.
No behavioural changes; no DB schema changes; safe drop-in upgrade for all installs.

1.1.1.15

WP.org Plugin Check compliance: Comprehensive code-quality sweep addressing every issue surfaced by the Plugin Check automated linter (155 findings total: 96 errors + 59 warnings). The plugin now passes the full Plugin Check rule set with zero findings.
Output escaping (53 fixes): Every variable echoed into HTML is now wrapped in esc_url(), esc_attr(), esc_html(), wp_kses_post(), or cast to (int). URLs are built unescaped and escaped late at output site (best practice). Pre-built HTML fragments returned from internal renderers (PCAL_Filters, PCAL_Month_Grid, PCAL_Week_View, PCAL_Day_View, PCAL_Photo_View, PCAL_Archive_List, PCAL_Thumb) are documented with phpcs:ignore comments explaining why they are safe.
Date functions (29 fixes): Every bare date() call replaced with gmdate() for deterministic UTC behaviour, except date_i18n() calls which intentionally use site locale.
Input sanitization (17 fixes): Every $_GET / $_POST read now uses wp_unslash() followed by an appropriate sanitiser (sanitize_key, sanitize_text_field, sanitize_email, absint, etc.). Read-only navigation parameters (filter inputs, view switching) are documented as such with phpcs:ignore for the nonce sniff since no data is mutated.
Nonce verification (21 fixes): All state-changing form handlers verify a nonce before processing input. Read-only display of redirect status flash messages is documented.
Translator comments (12 fixes): Every sprintf( __() ) / printf( esc_html__() ) call with placeholders now has a /* translators: */ comment directly above the gettext call for translator clarity.
Constants prefix (8 fixes): All plugin constants prefixed with PCAL_. The three WordPress cache-plugin standard constants (DONOTCACHEPAGE, DONOTCACHEOBJECT, DONOTCACHEDB) are documented with phpcs:disable since these names are fixed by the WP cache plugin ecosystem (W3TC, WP Super Cache, etc.).
Safe redirects (1 fix): Payment-gateway redirect now uses wp_safe_redirect() with the gateway host explicitly added via allowed_redirect_hosts filter.
File operations (1 fix): Replaced @unlink() with wp_delete_file() (WP.org-recommended wrapper). The one remaining file_put_contents() call (used to write a temporary .ics attachment that is immediately consumed by wp_mail() then unlinked) is documented with a justification comment.
Inline <style> removed: The dynamic colour-variables <style> block in class-pcal-assets.php is now attached via wp_add_inline_style() instead of being echoed from a wp_head hook.
No DB schema changes; no behavioural changes. This is a pure code-quality release.

1.1.1.14

Architectural change: The recurrence engine (recurrence authoring meta box, save handler, occurrence expander, RRULE parser) has been relocated from Lite into Site Calendar Pro 1.1.5. This brings Lite into compliance with the WordPress.org plugin-directory trialware guideline, which prohibits shipping locked feature code in a free plugin even when the lock is consensual. Lite-only installs no longer see the recurrence meta box at all; recurrence is now exclusively a Pro feature. The front-end calendar (Month grid and List view) gracefully shows each event as a single occurrence on its declared start date when Pro is not installed.
Compatibility: Sites running Site Calendar Pro must upgrade Pro to 1.1.5 alongside this Lite update. Pro 1.1.5 includes an activation guard that refuses to boot against Lite < 1.1.1.14; conversely, this Lite release relies on Pro 1.1.5 to provide the recurrence classes. Update both together.
Compliance: The "Powered by Site Calendar" credit is now OPT-IN. A new checkbox at Site Calendar → Settings → Appearance lets site administrators enable the credit; default is unchecked. The credit no longer appears anywhere on user-facing pages without explicit consent. (WP.org guideline on user-facing attribution.)
Compliance: The public REST endpoints (/wp-json/pcal/v1/events and /wp-json/pcal/v1/events/<id>) no longer return custom-field values that are marked as show_public=false. Internal-only custom fields are filtered out of the response. Authenticated integrations needing internal fields should register their own route with a proper permission_callback.
Compliance: RSVP form inputs (name, email, phone) are now sanitised with sanitize_text_field() / sanitize_email() at the earliest possible point in the submission handler, before being passed to attendee registration or payment-gateway buyer data.
Compliance: The Google Maps iframe embed on single-event pages is now disclosed in the readme's External services section, with links to Google's Terms of Service and Privacy Policy. The embed only fires when a venue address is present; events without a venue address render no map and produce no external request.
Compliance: Plugin text domain renamed from pro-calendar to getsitecalendar-lite across all 388 gettext call sites, matching the WordPress.org plugin slug. Translation files (if any exist downstream) will need to be re-keyed; no existing translations are bundled.
Fix: The "Subscribe to calendar" button and Add-to-calendar buttons stopped appearing in 1.1.1.12. The script enqueue is now correctly hooked to wp_enqueue_scripts (already fixed in 1.1.1.13 and retained here).
No DB schema changes; drop-in upgrade for Lite-only installs.
Housekeeping: bumped Tested up to to WordPress 7.0. Removed an internal-only MIGRATION.md development file that shouldn't have been included in the production build.

1.1.1.13

Fix: The "Subscribe to calendar" button and "Powered by Site Calendar" credit stopped appearing below archive/list views in 1.1.1.12. Root cause: the inline-script-to-enqueued-asset refactor in 1.1.1.12 called wp_enqueue_script() inside a wp_footer priority 99 callback, which runs AFTER wp_print_footer_scripts (priority 20) has already emitted the script tags — so ical-injector.js was never actually loaded on the page. The <template> element was correctly emitted, but the injector that reads it never ran. 1.1.1.13 moves the enqueue to the wp_enqueue_scripts hook so the script tag is emitted at the correct point in the page lifecycle. The Add-to-calendar button (Google/Outlook/.ics) on single-event pages was affected by the same bug and is also fixed.
No DB schema changes; drop-in upgrade.

1.1.1.12

Renamed display name to "GetSiteCalendar Lite" to make the WordPress.org directory listing distinctive. Text domain, class names, file names, option keys, custom post types, and shortcodes are all unchanged — this is a directory-listing rename only, with zero impact on existing installs.
Tested up to: WordPress 7.0.
Lowered admin menu position from 25 to 80 so Site Calendar sits below WordPress core items in the standard hierarchy.
Refactored 8 inline <script> and <style> blocks into proper wp_enqueue_script / wp_enqueue_style / wp_add_inline_script / wp_add_inline_style calls. New asset files: assets/js/ical-injector.js, assets/js/recurrence-ui.js, assets/css/help-screen.css. Affected screens: Settings (colour picker), single event page (Add to calendar), archive (Subscribe), Help admin screen, recurrence meta box, admin Add-Ons submenu styling.
Wrapped all 8 wp_verify_nonce() reads with sanitize_text_field( wp_unslash( ... ) ) per WordPress.org guideline that nonce inputs should be sanitized even though wp_verify_nonce is pluggable. Affected save handlers: event meta, featured flag, event options, venue meta, organizer meta, recurrence rule, RSVP form, plugin settings.
Tightened JSON-LD schema output in class-pcal-schema.php with explicit wp_json_encode() step and phpcs-ignore annotation justifying the deliberate non-escaping of the encoded payload.
Added inline justification comments above each public REST permission_callback => '__return_true' confirming that event, venue, and organizer GET endpoints are intentionally public read-only data, matching the visibility of the underlying posts.
No DB schema changes; drop-in upgrade.

1.1.1.11

New: A small "Powered by Site Calendar" credit is now shown next to the "Subscribe to calendar" button at the bottom of calendar views. Helps people discover the plugin. Power users can hide via add_filter( 'pcal_show_credit', '__return_false' ); in their theme, and Site Calendar Pro 1.1.3+ adds a one-click hide toggle in Settings → Appearance.
New: pcal_show_credit filter hook for full programmatic control of the credit.
No DB schema changes; drop-in upgrade.

1.1.1.10

Branded confirmation emails now read brand colours from Settings → Appearance. The HTML email's header bar and accent rules use your Primary and Accent colour settings; the QR code box uses a 6% tint of your Primary colour. Falls back to the classic dark-green / amber palette on sites that haven't customised their Appearance settings.
No DB schema changes; drop-in upgrade.

1.1.1.9

Mobile layout fix: editorial list view (?pcal_view=list) now stacks vertically below 720px wide. Previously the 280×170 featured image had flex-shrink: 0 set inline, which on phone viewports starved the title column to ~11 pixels wide — causing event titles, dates and excerpts to wrap one letter per line. The fix emits scoped !important CSS rules (necessary because the layout uses inline styles, specificity 1000) that flip the row to vertical-stack: date on top, image full-width, title and excerpt below.
No DB schema changes; drop-in upgrade.

1.1.1.8

[getsitecalendar_list] shortcode — the category attribute now accepts a comma-separated list of category slugs (e.g. category="1st-xv,2nd-xv,fixtures") with an OR-match. Works in both compact and classic layouts.
Paired with Site Calendar Pro 1.1.1+ for full multi-category support in the compact upcoming-list renderer.
No DB schema changes; drop-in upgrade.

1.1.1.7

Header fix: differentiated Plugin URI from Author URI to satisfy the WordPress.org pre-submission scanner. Plugin URI now points to the plugin-specific page; Author URI remains the company root. No functional changes.

1.1.1.6

Documentation: updated Contributors line for WordPress.org plugin directory submission. No code changes.

1.1.1.5

Documentation: corrected the Month view screenshot caption to accurately reflect what the view shows (clean overview grid; the Month view does not render full featured-image thumbnails). No code changes.

1.1.1.4

Readme tightened for WordPress.org submission. No code changes.

1.1.1.3

Settings → Appearance: new "Week view chip colour" picker. One picker drives the chip foreground, background, border and hover shades automatically.
New helper pcal_hex_to_rgba() for tinting colours; pcal_sanitize_hex() now accepts a per-setting fallback default.
Frontend emits four new CSS variables (--pcal-week-chip, --pcal-week-chip-bg, --pcal-week-chip-border, --pcal-week-chip-hover).
Drop-in upgrade; no DB schema changes.

1.1.1.2

Critical fix: restores the missing rsvp-mount.js so the Register / RSVP form actually appears on event pages. Without this file the form HTML rendered into the page footer but never mounted into a visible position. Strongly recommended for any site using ticketing or free RSVP.

1.1.1.1

List-view redesign — full-width editorial layout with the featured image on the right (280 × 170 lazy-loaded), title bigger and bolder, 28-word excerpt, and an inline ticket-pricing CTA in your brand colour.
Drop-in upgrade; existing list shortcode unchanged.

1.1.1.0

Featured-image thumbnails now render in the Month grid and List view, not just the Photo view.
New shared PCAL_Thumb helper class with three fallback paths: WordPress featured image at thumbnail size, a category-coloured icon tile (13 categories), or two-letter title initials in a brand-blue circle.

1.1.0.7

Restructured admin menus and added the Help tab with a friendly "Lite vs Pro — what's included" comparison.
Consolidated several fixes from the 1.1.0.4 – 1.1.0.6 point releases (Add-Ons submenu registration, ghost Tickets/Attendees menu entries removed, recurring-events upgrade nudge styling).

1.1.0.3

Fix: the "Need Recurring Events?" upgrade nudge under Date & Time was incorrectly suppressed in Lite. Now displays for all Lite users and is hidden only when Site Calendar Pro is actually loaded.

1.1.0.2

Removed the "Repeats" recurrence meta box from the event editor in Lite. Recurring events authoring is a Pro feature; recurrence storage helpers remain so any pre-existing _pcal_recurrence meta still renders correctly.

1.1.0.1

Domain change: customer-facing URLs updated to getsitecalendar.com. No functional changes.

1.1.0

Multi-organiser support per event.
Event Options sidebar box with "Sticky in month view" and "Hide from listings".
Per-venue map toggles ("Show map on event page" / "Show Get directions link").
Inline upgrade nudge for recurring events on the event editor (auto-suppressed when Pro is active).
"Calendar" admin-bar shortcut for All Events / Add New / Venues / Organizers / Settings.
Schema.org Event.organizer now emits an array when there are multiple organisers.
REST /events response includes both legacy organizer (single) and new organizers (array) fields.
Fully backward compatible.

1.0.0

First public release. Free core extracted from the commercial Pro Calendar codebase.
Includes Month / List views, venues, organizers, categories, basic weekly recurring events, free RSVP, ICS feed, REST API, schema markup.
