* Improvement - Improved admin panel styling with bigger input selection.
* Improvement - Admin panel create/edit: datetime row shows a loading state while product details, first-available auto-pick, day slots, or availability AJAX run; success/error only after the check completes.
* Performance - Admin panel create: first-available auto-pick scans the bookable horizon in 14-day chunks and stops at the first slot instead of loading the full range up front.
* Fix - Admin panel create: availability no longer flashes loading twice or clears to blank before first-available prefill; date-only calendar prefill waits for day slots before checking; browse does not re-open after the user closes it during the same unavailable episode.
* Fix - Admin panel: datetime loading no longer sticks when day-slot AJAX fails or returns empty, when a superseded availability request aborts, or while bootstrap waits only on an in-flight slots request (not missing cached data).
* Fix - Slots / day & month products: timed global RRULE blocks (e.g. weekly Tue 4–6pm) block the whole civil day again — date-level checks use RRULE occurrence expansion, not midnight-only overlap, so higher-priority global rules override product day rules (`RuleMinutesRruleCivilDayTest`).
* Fix - Admin panel browse: slot chips show remaining capacity (e.g. **1 available**) on multi-capacity products when only one place is left, not only when two or more remain.
* Fix - Slots: dynamic availability (indexing off) paints full half-open unappointable ranges on the minute mask — priority blocks no longer leave appointable boundary minutes (e.g. 10:00–11:00 block showing 10:59 slots); matches indexed mask painting.
* Fix - Slots / calendars: minute/hour bookings that start at site midnight (including long durations such as 12 hours) block capacity again — timed overlap day-keys use Fake UTC site civil buckets for both occupancy indexing and slot lookup instead of mixing wp_date() site midnight with the civil UTC-midnight fast path.
* Fix - Slots / calendars: multi-day day-unit occupancy for admin-created (site-local midnight) bookings — civil overlap keys use the site calendar date (Fake UTC) so every booked day blocks correctly (e.g. June 4–5 for a 2-day booking starting June 4); `wc_appointments_get_posted_data()` stores matching Fake UTC start/end for new day/month appointments.
* Fix - Slots / calendars: multi-day day-unit products block every booked civil day again — occupancy uses live appointments; overlap day-keys use timezone-agnostic civil dates (gmdate on stored tokens), matching slot tokens, not wp_date() site-local midnight.
* Fix - Admin panel **create**: first available date/time via one AJAX call (`WC_Appointment_Slots_Provider::get_first_available_slot`, same as storefront), including when the first slot is outside the current month; calendar day click/drag date-only prefill auto-picks the first time or opens browse once with `noSlotsOnDateSelect` when that day has no slots; browse auto-opens only on unavailable validation (not during silent auto-pick) and stays dismissible (no immediate re-open after close until date or product changes); live preview placeholder while slots load; panel expands when the product form is ready.
* Fix - Slots / calendars: minute/hour day availability (storefront `day_data`, admin mini-calendar, time-slot lists) counts only bookable slot starts via shared `WC_Appointment_Slots_Collection::slots_for_day_summary()` on the same `get_collection()` engine — fully booked days no longer stay selectable when only sub-duration engine segments remain.
* Fix - Slots / time picker: **Availability check → The starting slot only** no longer lists grid starts in appointable fragments shorter than the booking duration (phantom evening slots such as 19:00 on 12h/12h products when the index leaves a tail after a gap); full-day ranges still allow starts when duration exceeds the window (e.g. 25h in 24h).
* Fix - Checkout validation (`WC_Appointment_Cart_Manager::validate_appointment_order`): re-validates cart slots via `WC_Appointments_Controller::get_indexed_total_available_for_range()` (same `slot_matches_requested_range` tolerance as add-to-cart) instead of strict `start_ts` equality; **all staff together** uses staff id `0` fan-out like `is_appointable()`; in-cart holds are excluded from overlap during the check.
* Fix - **Staff all together:** cart booking no longer collapses multi-staff `_staff_ids` to a single `_staff_id` during `WC_Appointment_Booking_Handler::create_appointment()` availability merge.
* Fix - Admin panel: **WooCommerce Deposits** on create — `calculate_costs` / `create_appointment` honour deposit choice and tax display (incl./excl. catalog); deposit footer quote and order item meta (`_deposit_full_amount`, etc.) match storefront; pay-deposit hides footer price edit (product deposit rules); pay-in-full edits full service price via `raw_full_price`; mistaken deposit-only overrides corrected on save.
* Feature - WooCommerce block email editor support for appointment transactional emails (synced block templates under templates/emails/block/, hook-driven parts under templates/emails/parts/, personalization tags, preview context, admin styles).
* Improvement - Date picker default date uses `WC_Appointment_Slots_Provider::get_first_available_slot()` which leverages Collection day summaries to skip unavailable days. Complexity reduced from O(all_slots) to O(days + slots_in_first_available_day).
* Improvement - `WC_Product_Appointment::get_first_available_slot()` and `get_slots_in_range_lazy()` (and private `get_slots_lazy_by_duration` / `get_slots_in_range_for_*_lazy` helpers) removed; use `WC_Appointment_Slots_Provider::get_first_available_slot()`.
* Improvement - Removed deprecated dead code with no external calls: 11 methods from `WC_Appointments_Controller` (deprecated 2.4.9–4.7.0), 5 functions from `wc-appointments-functions.php` (deprecated 1.15.0–5.1.0), and 3 methods from `WC_Appointment` (deprecated 4.2.0–5.3.8). Deprecated code still in use internally was retained.
* Improvement - Removed deprecated dead code from `WC_Product_Appointment`: get_time_slots(), get_time_slots_html(), get_slots_availability(), get_all_staff_availability(), get_min_timestamp_for_date(), get_available_appointments(), get_appointments_in_date_range(), get_unavailable_minutes(), get_minutes_from_rules(), get_available_slots(), get_slots_in_range(), get_slots_in_range_for_day(), get_slots_in_range_for_month(), get_slots_in_range_for_hour_or_minutes(), get_appointable_minute_start_and_end(), get_appointable_minute_slots_for_date(), get_max_allowed_date_into_the_future()
* Improvement - Removed deprecated dead code from `WC_Appointment_Slots_Legacy_Adapter`: get_time_slots(), get_available_slots()
* Improvement - Admin appointment panel (`wcaPanel`): localized incl./excl. tax short labels from WooCommerce; footer cost hint and add-on section respect `wc_prices_include_tax()` and whether tax is enabled; AJAX posts (`wc_appointments_panel_cost_excl_tax`, add-on incl./excl. flags, override excl. flag) only when the catalog is exclusive so net/gross semantics stay consistent.
* Improvement - Product Add-Ons integration: panel AJAX uses filters so admin add-on price display and suffix follow the same inclusive/exclusive catalog basis as the appointment panel.
* Improvement - Admin appointment block templates: admin edit link uses the same `printf( esc_html__( … ), '<!--[tag]-->' )` pattern as WooCommerce core block emails (e.g. store email / customer name in default content).
* Improvement - Update translations (+19 new strings).
* Fix - Admin product **Custom availability** rows (`html-appointment-availability-fields.php`): date/time display no longer converts using `get_staff_timezone( get_current_user_id() )`, which applied the **viewing user’s** saved appointment timezone to everyone (including administrators). Uses `WC_Appointments_Timezone_Helper::get_admin_user_timezone()` so **store admins and shop managers** see **site** wall times; **staff-only** users still see their profile timezone. Google/RRule summary only treats `kind_id` as a staff user when the rule `kind` is `availability#staff` (not product/global `kind_id`).
* Fix - Admin user profiles now show a single appointment timezone selector for all users. Staff profiles use the shared field while keeping the staff profile navigation section and enhanced searchable timezone picker.
* Fix - Indexed availability: manual **Re-index** no longer raises per-rule limits so high (e.g. thousands of RRULE occurrences or a full year of days in one pass) that a single AJAX chunk could hit browser/proxy timeouts despite batching. `WC_Appointments_Cache_Availability::run_rule_index_pass()` uses modest multiples of the normal per-pass caps; rules that still need more work are re-scheduled as before.
* Fix - Unified slots when a **specific staff** is selected: `WC_Appointment_Slots_Rule_Resolver::build_minute_mask` (dynamic rules) and `WC_Appointment_Slots_Data_Normalizer::build_minute_mask_from_index_rows` (indexed cache) now apply matching **staff**-scope rows **inline** on the main minute mask in sorted override order, instead of replacing the mask with a staff snapshot that could resurrect minutes a **higher-priority** global/product **not available** row had already cleared. Rule priority vs. staff overrides now match between indexing on and off.
* Fix - Indexed full-day row types **`days` / `months` / `weeks`**: minute-mask painting clamps the day span at **1440** minutes (end of civil day) so the mask tail past midnight is not left appointable from index timestamps; avoids rule-blocked calendar days appearing clickable when availability indexing is enabled.
* Fix - Legacy storefront calendar payload (`WC_Appointment_Slots_Legacy_Adapter::collection_to_scheduled_days`): days with **`unavailable`** status are also copied into **`fully_scheduled_days`** for the same date keys, because `date-picker.js` treats **`fully_scheduled_days`** as non-clickable; rule-only unavailability no longer leaves those days selectable when the modern `day_data` path already marks them closed.
* Fix - Admin appointment panel: create success schedule line uses store date/time formats (`wc_appointments_date_format` / `wc_appointments_time_format`); when the acting user’s admin timezone differs from the site, text is derived from start/end timestamps via `wc_appointment_timezone_locale` so it matches the times they picked. Timezone context uses `abbr.wc-appointments-tz-abbr` beside the line (same pattern as the edit panel When row), not parenthetical suffix text.
* Fix - Admin appointment panel edit mode: footer no longer shows a live-calculated price (slot/product rules); it could disagree with view-mode order line totals, and cost is not editable there. View mode still shows pricing from the order.
* Fix - Admin appointment panel: create submit sends `wc_appointments_field_start_date_timestamp` when a slot is selected so server cost matches the footer (fixes line total 0 when the price field was never focused). Order line total always adds Product Add-Ons to the appointment base; price override prefills/commit uses appointment base only (footer raw minus addon cost) so add-ons still apply after touching the price input.
* Fix - REST `GET wc-appointments/v2/appointments/{id}`: embedded `order_info` now matches calendar batch order payloads—each line item includes `subtotal_tax` / `total_tax`, and the order includes `total_tax`, `discount_tax`, and `coupon_lines`. The admin appointment **view** panel Cost/Tax row uses these fields on first open; previously they were omitted so Tax could appear only after closing and reopening (calendar-loaded appointments already had the fuller shape).
* Fix - Admin manual appointment creation when WooCommerce **prices are entered inclusive of tax**: AJAX cost display and order line totals align with the inclusive/exclusive catalog basis (appointment base + Product Add-Ons as one tax-aware bundle on the line so `calculate_totals()` does not stack VAT on top of tax-inclusive amounts).
* Improvement - Admin calendar: on expired nonce/session (REST 401/403), show an expiry banner with reload link instead of failing silently after long idle periods.
* Improvement - Admin appointment panel: create/edit success step uses a light success-tinted circular badge for the checkmark (aligned with other success affordances), not a plain large icon.
* Improvement - Update translations (+2 strings, −11 strings removed).
* Dev - Removed deprecated per-product `customer_timezones`; timezone support is site-wide. `has_timezones()` now reads `wc_appointments_timezone_support_enabled` (default `true`). Removed `get_customer_timezones` / `set_customer_timezones`, related data store mapping, admin and REST fields, and WCML/Polylang sync for that setting.
* Fix - Admin timezone display: `appointments_time_zone` cookie no longer applies in admin/REST. Only staff (providers) may use profile timezone in admin; admins and shop managers always see site timezone. Remote staff can still set profile timezone.
* Fix - Admin create flow, existing order: order number no longer appears twice in Select2 and the selected chip—both prefixed `#` + internal ID onto labels that already included the display order number.
* Fix - Legacy calendar staff view: staffed appointments no longer also list under Unassigned—`$is_creator` matched `creator_id === 0` because `(int) 'unassigned' === 0`; creator shortcut now requires non-zero `creator_id`.
* Fix - Manual appointment on existing order (admin AJAX): line meta used public `appointment_id`, so emails/item meta showed an extra row. New rows use `_appointment_id` only (checkout parity); formatted order item meta strips legacy public `appointment_id` for display.
* Fix - Admin browse day slots: discounted `price.display` (`<del>` / `<ins>`) was React-escaped; `.wca-slot-price` now renders with `dangerouslySetInnerHTML` (same as panel footer).
* Fix - Recurring `time:range`: same-day windows ending at **`00:00`** were misclassified as overnight (**string** order: **`00:00` < `08:00`**, **`24:00` < `08:00`**). `WC_Product_Appointment_Rule_Manager` / `WC_Appointment_Slots_Rule_Minutes` now use minute-based wrap helpers (`is_wrap_midnight_hhmm_pair` / `is_wrap_midnight_time_pair`); `evaluate_rule_for_timestamp` shares the same bounds. Availability cache indexing aligns with slot rules for **`00:00`** end-of-day, maps **`24:00` → 1440**, and sets same-day **`eff_to_min = 1440`** when needed. **`time:range` overnight** at midnight merges evening (**from–24:00**) with morning (**00:00–to**) when the prior day is in range (**`RuleMinutesMidnightWrapTest`**).
* Fix - Unified slots + `woocommerce_appointments_slots_display_pricing`: `WC_Appointment_Slots_Pricing::compute_slot_price_raw()` returns the full filtered slot price when the filter runs (not only when below default). `WC_Appointment_Slots_Collection::serialize_slots()` writes `price_data.display` / `price_formatted` HTML; the lazy formatter had read a non-array `price` from `jsonSerialize()`, so strikethrough/sale never reached unified JSON.
* Fix - Availability rules: changing `range_type` (e.g. Date range with time → Days) clears unused `from_date` / `to_date` via `apply_json_rule_to_availability()` (`time:range`, `custom:daterange`, `store_availability` still keep dates), so weekly/monthly rules are not skewed by stale columns.
* Fix - Indexed availability cache: indexer ignores stray `from_date` / `to_date` on **`days`**, **`months`**, **`weeks`** (same as recurring `time` / `time:N`), so corrupt rows no longer shrink the cache window until re-saved.
* Fix - Admin appointment save (`WC_Appointment_Meta_Box_Data::meta_box_save`): failed start/end validation now sets `self::$saved_meta_box` before return (matches success path), avoiding duplicate admin errors or extra `save_post` work in the same request.
* Fix - Day-unit products when add-ons (or `appointment_form_posted_total_duration`) extend past base duration: `WC_Appointments_Controller::get_exact_available_capacity_for_slot()` no longer uses the multi-day “start row only” shortcut (it skipped later days) or `get_extended_range_available_capacity()` for that span (UTC civil-day mismatch caused false unavailability). Added `get_addon_extended_day_span_capacity()` (same UTC keys as `get_multi_day_available_capacity()`, min capacity across span days). Minute/hour add-on extension unchanged.
* Improvement - What's New admin screen (`html-wc-appointments-whats-new.php`): **admin appointment panel** behavior is now described and illustrated clearly—by default the panel **anchors beside the selected calendar appointment** (prefers right, then left, centers only when neither side fits), with backdrop and roadmap/changelog wording aligned. This replaces misleading “side panel” / generic sidebar copy and SVGs that did not show the panel next to the trigger event.
* Fix - Admin appointment save (`WC_Appointment_Meta_Box_Data::meta_box_save`): blank or invalid start/end date (or missing time when not all-day) no longer calls `mktime()` with non-integer parts (PHP 8+ TypeError / fatal). Invalid input shows a WooCommerce admin error and the appointment object is not updated on that request.
Improvements
Unified Slots Standardization (part 1): WC_Appointment_Slot embeds projected business/display TZ metadata, wall times, formatted labels, status/bookable, and selection helpers so storefronts render slots without extra timezone math.
Slots provider/engine accept optional display_timezone; WC_Appointment_Slot:😛roject_display_fields() centralizes projection; resolve_display_timezone() pins day/month and non-timezone products to business TZ and validates IANA zones for timed products.
WC_Appointment_Slots_Collection::get_day_summaries_by_display() groups by display_day; calendar AJAX includes display_day_summaries while legacy scheduled_days remains for compatibility.
WC_Appointment_Day_Summary JSON adds display_day, display_date_formatted, selectable, and first/last slot hints sourced from projected slots.
Fixes
Bundled Product Add-Ons integration JS: strip esbuild's top "use strict" in build-js-addons; initialize window.WC_PAO; declare quickview product_price; broaden PaoValidation minify post-replace for renamed locals.
Slots engine: time-slot start step again uses the product interval (base) when it differs from duration (e.g. 90 min service every 2 hours). 5.3.4.1’s min(duration, interval) grid for all minute/hour products had caused starts every 90m instead of every 120m in that case; duration only defines block length, not the cadence between start times.
Fixes
Day-duration availability and checkout validation are now timezone-agnostic across both negative and positive UTC offsets by aligning day-key generation and matching in slot display, indexed capacity lookup, and multi-day fallback validation.
Rule capacity evaluation now correctly returns zero for non-appointable matches in capacity mode, preventing disabled all-day dates from appearing available when global and product-level rules overlap.
Availability rule sorting now applies time-rule specificity only when comparing two time-family rules, so date-specific unavailability (custom/date-range) no longer gets overridden by weekday time rules on the same day.
Indexed availability: availability rules saved while the indexed cache is disabled are queued and processed when indexing is turned back on (bounded synchronous pass for the first batch, Action Scheduler for overflow), avoiding empty or stale cache after long periods with indexing off.
Indexed availability: custom rules that only store YYYY-MM-DD bounds in from_range/to_range (with empty from_date/to_date) now anchor the indexer to that window so far-future custom blocks are not skipped on the first bounded pass.
Indexed availability: open-ended recurring non-RRULE rules (weekday time:*, days, months) prime through the cache horizon on a cold first pass instead of only the per-pass day chunk, so recurring weekdays do not disappear until background continuation runs.
Admin create success message now uses canonical server-provided schedule text to prevent date shifts caused by client-side timezone reformatting.
Multiple appointment_form shortcodes/blocks on the same page now keep datepicker state isolated per form; with auto-select enabled, one form no longer shifts another form's calendar month/year.
PHP 7.4 compatibility: removed PHP 8.0+ union return types from several methods (e.g. string|false, WP_REST_Response|WP_Error) that caused parse errors on PHP 7.4; @return PHPDoc preserved so behavior and tooling contracts stay documented.
PHP 7.4 compatibility: slots subsystem (value objects, collection, engine, provider, legacy bridge, REST v2 slots) no longer uses PHP 8.0+ syntax that failed to parse on PHP 7.4 — readonly typed properties, named arguments in WC_Appointment_Slot construction, trailing commas in function parameter lists, and match (replaced with equivalent switch / conditionals). Runtime slot math and responses are unchanged.
PHP 7.4 compatibility: Google Calendar (WC_Appointments_GCal) and the appointment product model (WC_Product_Appointment) no longer declare PHP 8.0+ union types on properties (int|false, string|false, int|string|false); types are documented in PHPDoc and values/behavior stay the same.
* Fix - REST API v1: Fixed critical bug in Products controller where appointment-specific fields (duration, interval, staff assignments, etc.) could not be updated via PATCH/PUT requests due to incorrect use of array_keys() in the update loop.
* Fix - Timezone display setting now only controls timezone UI/selection by context (frontend/admin/all); when disabled, timezone picker behavior is suppressed and booking/slot/cost calculations consistently fall back to site timezone.
* Fix - Google Calendar: Importing or restoring synced availability rules (including backup restores) no longer triggers rule sync to Google Calendar.
* Improvement - Clear date, time, addons and cost on month/year switching on the date picker.
* Improvement - Remove all transient caching from the slot generation, actually slows down loading with indexing enabled.
* Improvement - Add a fail-safe approach to "woocommerce_appointments_time_slots" filter by adding back the 10th arg.

* Fix - Staff permission for editing and creating products not working, but should grant staff access to all products.
* Fix - Automatically assigned staff together issue when no staff assigned. Issue #1292.
* Fix - Patch non-indexed path where showing sold out slots could trigger fatal error through filter.
* Fix - Minimal CSS patch to prevent transition effect (added elsewhere) on datepicker back/forward buttons.
* Fix - Patch to show status drodown correctly on appointment viewing modal when statuses have long translations.
* Fix - Timezone change to UTC on frontend not working. Issue #1294.
* Fix - Timezone text on frontend not changing when selecting default. Issue #1295.
* Fix - Timezone overnight change not reflected on the calendar date picker. Issue #438.
* Fix - Appointment vierwing modal shows wrong duration for daily or monthly duration types. Issue #1296.
* Fix - Timezone should also be added to daily and monthly durations during creation or editing in admin calendar. Issue #1296.
* Fix - When product is selected in modal, end date/time is not adjusted based on product duration.
* Fix - When staff creates appointment in modal, they should be assigned to the product, not any other staff member.
* Fix - When staff is logged in, admin calendar should server preload appointment for the staff, but loads the via API (slower).
* Fix - Fix get_slots_availability to expand DB query range by padding. Issue #1256.
* Fix - Fix indexed path to include padded range more strictly. Issue #1256.
