20264 releases

  1. Booking Manager 2.1.22Latest

    • Improvement Added an option to include bookings from child capacity resources in a parent resource’s .ics feed, while preserving parent-only export as the default.

  2. Booking Manager 2.1.21

    • Security Hardened iCalendar import UID lookups and restricted interface preference updates to the signed-in user’s own settings. Thanks to Mohamed Bassia and Choriyev Qahramon (ciprobe) for responsible disclosure.

  3. Booking Manager 2.1.20

    • New * Added support for the “Append extra day after imported checkout day” import option. When enabled together with “Append check out day”, imported .ics events will include one additional day after the imported checkout day before applying check-in/check-out times.
    • Fix Parent-resource .ics feeds in Booking Calendar Business Large now export only dates assigned to the parent resource, preventing bookings occupying child resources from being included.

  4. Booking Manager 2.1.19

    • Fix Hardened Listing Template settings by restricting access to manage_options and sanitizing listing_template on save and render while preserving safe HTML/placeholders

20258 releases

  1. Booking Manager 2.1.18

    • Fix Fix XSS during listing of .ics feed content, if the .ics file was broken or intentionaly inject by malicious script. (2.1.18.1)

  2. Booking Manager 2.1.17

    • Fix If enabled “Use selected times for each booking date” option on the WP Booking Calendar > Settings > Calendar > Calendar Settings page, system imports time slots, instead of check in/out times for such bookings. (2.1.17.1)

  3. Booking Manager 2.1.16

    • Fix Timed events where end <= start (equal or earlier, e.g., due to a bug or reversed inputs) -> you now get a minimal valid span of +1 hour. Previously this produced invalid ICS (“DTEND before DTSTART”).
    • Fix All-day events where end ≤ start -> coerced to +1 day (exclusive end), which matches iCal semantics for single-day all-day events.
    • Fix So: for correctly formed bookings, durations are identical. The only “change” is that bad/zero/negative durations are repaired to a minimal valid length so calendars won’t reject the feed.

  4. Booking Manager 2.1.15

    • Improvement Block import/delete shortcodes on non-published posts/pages to prevent unintended actions during review. (2.1.15.1)

  5. Booking Manager 2.1.14

    • Improvement Improved iCal/ICS export for full compatibility.
    • Improvement Reworked recurring and multi-date export logic: now generates one VEVENT per date/range instead of RDATE rules, ensuring full compatibility with Google Calendar, Outlook, Apple Calendar, Booking.com, Airbnb, and other iCal consumers.
    • Improvement Corrected date handling to respect the site’s timezone for both all-day and timed events, preventing off-by-one-day issues.
    • Improvement Added safer UID generation and consistent metadata for better sync reliability.

  6. Booking Manager 2.1.13

    • Fix: When accessing the .ics calendar feed for a parent booking resource (with specific capacity) in Booking Calendar Business Large, only bookings from the parent resource are now exported.

  7. Booking Manager 2.1.12

    • New: Added option “Export only full days (not time)” on “oPlugins Panel > Settings General”, to export only full days without time to the .ics feed. This is a limitation in Airbnb and some other services. (2.1.12.1)
    • Fix Notice: Function _load_textdomain_just_in_time was called incorrectly. (2025-04-04)
