ICS Calendar

Přehled změn

11.0.0.1 – 2024.04.18

• Fixes an issue with HTTP headers in the new method of retrieving ICS feeds. The issue was hotfixed approximately one hour after the initial release, but some sites may have picked up the update within that hour. This update also increases the timeout from 5 to 30 seconds, to address potential issues with retrieving very large ICS files.

11.0.0 – 2024.04.18

PLEASE NOTE: This version includes a significant rewrite of the function that retrieves the contents of ICS feed URLs. It is now using the built-in wp_remote_get() WordPress function (instead of PHP cURL and fopen functions as before), so it should be fully compatible with all existing installations. However, if you encounter any new issues, please visit the WordPress Support Forums for assistance.

• Admin Settings:
  • Added Allow access to these hostnames that resolve to reserved IP addresses setting. This allows sites to access calendar servers on the same physical IP address as the web server, or within the same internal network. Previously this needed to be handled using custom PHP code as outlined in this blog post.
• Code Refactoring:
  • Replaced previous cURL and fopen logic with wp_remote_get() in R34ICS::_url_get_contents() method. Correspondingly, deprecated the curlopts and method parameters. Note: The second and fourth parameters of the protected method R34ICS::_url_get_contents() were removed rather than deprecated. No external plugins should be using this method other than ICS Calendar Pro, which has been correspondingly updated.
  • Removed admin notice checking for presence of cURL or fopen functions.
• WordPress Playground:
  • Added r34ics_is_playground() function to detect if running in WordPress Playground.
• Miscellaneous:
  • Added missing fourth parameter to r34ics_event_description_html action.
  • Changed Room 34 Creative Services logo link on admin page sidebar.
  • Fixed PHP warning in r34ics_system_report() in rare situations where get_option('active_plugins') returns a plugin that is not included in get_plugins(). (May occur if the plugin has been manually removed from the file system.)
  • Modified R34ICS::event_description_html() to handle $event['start_time'] and $event['end_time'] as alternatives to $event['start'] and $event['end'].
  • Updated header details in ics-calendar.php.
• a11y:
  • Changed CSS for .ics-calendar-arrow-nav > *.inactive to completely hide inactive arrow navigation elements (e.g. „Previous“ while on first month, „Today“ while on current month, etc.) rather than screening back their opacity. Modified jQuery corresponding to these elements to dynamically add aria-hidden="true" when inactive class is added.
• i18n:
  • Added and updated translation strings.
• Bumped ‚tested up to‘ version to 6.5.2.

10.14.1.5 – 2024.04.05

• AJAX:
  • Fixed logic that replaces FILTER_SANITIZE_STRING (introduced in version 10.13.1.1) to properly account for array values in shortcode parameters.
• List and basic views:
  • Eliminated unnecessary JavaScript fade-in on load, except when pagination or ajax option is in use.

10.14.1.4 – 2024.04.01

• General:
  • Fixed issue with extendmultiday where it would extend one-day events as well as multi-day events.
• List and basic views:
  • Added detection of the „current“ page when pagination is turned on. The page will now automatically load with the page containing the current date displayed, instead of the first page, making list and basic views with pagination more useful when pastdays is set to include past events in the list. (Note: The pagination is set independently of the date, so it’s possible the page may still load with a few past events displaying before the current date’s events, but the current date’s events will be on the page.)
  • Minor template code refactoring.
• Month and week views:
  • Added call to r34ics_show_hide_headers() function when clicking „Show past events“ on mobile, as a possible solution to a client-side issue with date headers not displaying when the window is left open over a break between months. (Due to the nature of the bug, it can only be tested at the transition between months.)

10.14.1.3 – 2024.03.08

• AJAX:
  • Added failure handling that will retry the AJAX request up to 5 times in situations where the AJAX response is only 1 instead of the proper calendar HTML output. After the fifth failure, AJAX will report ICS Calendar AJAX request failed for element... to the JavaScript console. (Previous versions would fail in this way after one attempt.)
• Bug fix:
  • Modified conditional introduced in version 10.14.1.2, to resolve possible Undefined array key "VALUE" PHP warnings.
• Misc:
  • Removed unnecessary global $wp_locale; line from all templates.
  • Added changelog.txt and moved older changelogs to that file; truncated changelog in readme.txt to comply with WordPress repository requirements.
• Bumped ‚tested up to‘ version to 6.5.

10.14.1.2 – 2024.03.06

• Added a workaround for a possible issue with the ics-parser library on recurrence exclusions (EXDATE) where excluded event dates are still being included in the output array.
• Updated embedded ics-parser library to v. 3.3.1 (carrying over existing modifications).

10.14.1.1 – 2024.02.21

• JavaScript:
  • Replaced wp_localize_script() with the now-preferred wp_add_inline_script() in R34ICS::enqueue_scripts() method. Fixes an issue where the „localized“ script was not actually rendering in the page in some situations.
  • Modified logic that hides „Show past events“ on mobile month/week views, when there are no past events in the current month, to account for the .month_list_all class (an ICS Calendar Pro-only feature).

10.14.1 – 2024.01.25

• Added Remove „Add ICS Calendar“ button in Classic Editor admin option to leverage the existing r34ics_display_add_calendar_button action without the need for custom PHP code.
• Added r34ics_purge_calendar_transients action to allow external cleanup functions to fire off on the Clear Cached Calendar Data utility.
• JavaScript: added type casting to r34ics_boolean_check() function to prevent occasional AJAX loading errors.
• i18n: New translation strings.

10.14.0 – 2024.01.11

• AJAX:
  • Encapsulated AJAX client-side logic in a new r34ics_ajax_init() function, and added r34ics_ajax_start and r34ics_ajax_end events.
  • Two changes to address the issue of AJAX requests occasionally outputting only „1“ instead of the calendar:
  1. Added a check on the R34ICS::display_calendar() method for transient data containing only „1“ instead of the calendar, bypassing the transient cache if true.
  2. Added handling to the AJAX output itself to suppress display of the „1“ if it still occurs, and write an error message to the console. We are still investigating the root cause of this issue.
• JavaScript:
  • Added JavaScript version of r34ics_boolean_check() function.
• List view:
  • Added text underline to events that have a clickable description when the toggle option is turned on, to give users a visual cue.

10.13.1.1 – 2023.12.16

• AJAX: Replaced FILTER_SANITIZE_STRING, deprecated in PHP 8.1, with a new sanitization method, and added conditional to prevent processing the AJAX output if URL is missing.

10.13.1 – 2023.12.08

• Basic view:
  • Switched event layouts to use CSS flexbox instead of float, to address issues where long event titles may force all text to wrap below the date block.
  • Additional minor CSS adjustments.
• Month view:
  • Added „Today“ link to header navigation. Requires monthnav to be set to an option that includes the previous/next arrows (all except the default select).
  • Fixed bug that would prevent „Show past events“ link from appearing in mobile breakpoint under certain conditions.
• i18n: Added new translation strings.

10.13.0.2 – 2023.12.04

• Added missing logic to turn off caching if debug="3" is set; refactored logic for setting reload value.
• Adjusted CSS for event hover effects to improve performance in some views in the Pro version.
• Narrowed jQuery selector scope for pagination logic in List and Basic views, to fix a conflict with some views in the Pro version.

10.13.0.1 – 2023.11.28

• Fixed a display bug introduced in v.10.13.0 that would cause broken HTML code to appear directly on the page for some sites. (The default values for the new htmltageventtitle and htmltageventdesc parameters were not being set correctly for sites with the Use new parameter defaults (v.10.6) setting turned off.)
• Renamed new r34ics_filter_allowed_heading_tags() function to r34ics_allowed_heading_tags_check(), since it’s not technically a filter.
• Hotfix: Added .event-info wrapper element in Basic view to prevent longer event descriptions from wrapping below the floating date block element.

10.13.0 – 2023.11.27

• New Features:
  • Added new „Basic“ view. Use view="basic" in your shortcode. This is a variant of List view that does not group events by date/month. By default, the date of each event is displayed in a prominent date box. For a „true“ basic view, also add nostyle="true" to your shortcode. This view supports most of the same parameters (and associated functionality) as List view, including count, pagination, color, eventdesc and toggle.
  • All views: Added <span> wrapping of date elements (day of week, month, day number, year, etc.) with a new data-date-format attribute on each tag. Allows for custom styling of the components of a date. This feature is used for the date boxes in the new Basic view, but also allows for custom styling of List view.
• New shortcode parameters:
  • htmltageventdesc: Sets the HTML tag used for the .eventdesc element on events.
  • htmltageventtitle: Sets the HTML tag used for the .title element on events.
  • htmltagtime: Sets the HTML tag used for the .time element.
  • nostyle: Turns off most of Basic view’s default HTML styling for a „true“ basic view that you can customize with your own CSS. (Currently has no effect on any other views.)
• New filter:
  • r34ics_display_add_calendar_button: Use with the __return_false function to turn off the „Add ICS Calendar“ button in Classic Editor.
• Functionality changes:
  • The paginationposition parameter in List and Basic views now defaults to above rather than below.
  • Minor code refactoring in templates/calendar-list.php and functions.php.

10.12.2 – 2023.11.13

• Admin Utilities:
  • Removed raw data output from ICS Feed URL Tester utility.
  • Minor refactoring of r34ics_system_report() function.
• Security:
  • Streamlined URL validation code added in v.10.12.0.4 to remove redundant custom logic, and instead rely on the WP core [wp_http_validate_url()](https://developer.wordpress.org/reference/functions/wp_http_validate_url/) function. This change also adds the ability for site developers to use the [http_request_host_is_external](https://developer.wordpress.org/reference/hooks/http_request_host_is_external/) filter to selectively grant access to specific internal network URLs, e.g. for retrieving ICS feeds from locally hosted mail/calendar servers.
  • Restricted debugging data collection to users with the Administrator role, and removed raw retrieved URL data from all debugging tools.
• i18n:
  • Updated translation strings.
• Vendors:
  • Updated ICS Parser library to 3.3.1 (with modified namespace, as usual, to avoid plugin conflicts).

10.12.1 – 2023.11.06

• Bug fix: Corrected CSS logic for combinemultiday that would incorrectly display event titles if site’s Week starts on value was anything other than Sunday.
• CSS: Tweaks to compact in Month and Week views.
• Hooks: Added r34ics_eventdesc_include_time_and_title filter. This allows for additional external conditionals to determine whether or not the time and title for events should be included in the .eventdesc element.
• Misc: Removed a few redundant lines of code.

10.12.0.4 – 2023.10.30

• Added an extra security check for extremely rare conditions where the security fix added in versions 10.12.0.2 and 10.12.0.3 may not have been adequate. This fix has been backported to all earlier affected versions of the plugin in the repository.

10.12.0.3 – 2023.10.24

• Critical bug fix: Addresses an additional condition of the same issue first addressed in 10.12.0.2. This is not a second bug, rather a more thorough and effective solution to the same bug. This fix has been backported to all earlier affected versions of the plugin in the repository.
• Drobné změny v kódu.

10.12.0.2 – 2023.10.23

• Critical bug fix: Addresses a security issue identified in earlier versions of the plugin. Per best practices we are not identifying the specific details of the issue or the fix. This fix has been backported to all earlier affected versions of the plugin in the repository.
• Removed unnecessary retrieval of /etc/issue file contents from r34ics_system_report() function. (This is unrelated to the critical bug fix noted above.)

10.12.0.1 – 2023.10.16

• Bug fix: Added stopPropagation() to jQuery logic for toggle feature. The modified selector added in version 10.12.0 was inadvertently causing the code to run twice (instantly re-closing the toggle) when clicking on the event title itself.

10.12.0 – 2023.10.06

• a11y: Added tabindex="0" to all events and corresponding CSS changes to make event hover descriptions tab-accessible. Note: We are still troubleshooting some issues with tabbing to links contained within the description block. However, we are releasing this feature as-is due to the immediate accessibility improvements it can offer.
• Developer: Removed deprecated filter names.
