PrefixAllGlobals. * Code: added phpcs.xml with explicit prefix configuration so local PHPCS enforces the same rule. #### 1.0.24 * Code: rewrote timeline-script.js to pass WordPress PHPCS standard (tabs, multi- line call formatting, @package tag, period-terminated inline comments). #### 1.0.23 * Improvement: “Show Era Boundary” toggle — displays a styled divider line between BC and AD entries on the timeline. * Improvement: “Era Terminology” radio — choose BC/AD (traditional) or BCE/CE ( modern). Applies to year labels and the divider. #### 1.0.22 * Improvement: Settings > “Show Year Labels” toggle — uncheck to hide the year column and display a compact full-width timeline. * Improvement: any change to a plugin setting now automatically busts the shortcode transient cache. #### 1.0.21 * Improvement: year field now accepts BC dates (-9999 to 9999). Enter -2580 for 2580 BC. * Improvement: BC years display as “2580 BC” on the timeline and in admin columns. * Fix: negative years were stripped to positive by absint(); now uses intval() to preserve sign. * Fix: sort timestamp falls back to year × 31 557 600 when strtotime() cannot parse ancient dates. #### 1.0.20 * Improvement: “Show Today” toggle in Settings — displays a hollow marker at today’s date position, sorted correctly among all entries. Works even with no real entries. Bypasses transient cache while active. #### 1.0.19 * Fix: entries dated exactly 1970 (Unix epoch, timestamp = 0) were incorrectly filtered out and never displayed. #### 1.0.18 * Improvement: added Settings page under Timeline menu with shortcode reference( all attributes, defaults, examples) and existing categories with ready-to-use shortcodes. * Improvement: color pickers on Settings page let admins change the timeline line color and dot color without editing CSS. #### 1.0.17 * Fix: replace named global function in uninstall.php with call_user_func closure to eliminate global namespace warnings. #### 1.0.16 * Fix: wrap uninstall logic in a prefixed function to avoid global variable scope warnings. #### 1.0.15 * Fix: removed load_plugin_textdomain() — WordPress auto-loads translations since 4.6. * Fix: prefixed global variables in uninstall.php to avoid namespace collisions. * Fix: added phpcs:ignore for the_content core hook (not a custom hook). * Fix: updated “Tested up to” to WordPress 6.9. #### 1.0.14 * Improvement: CSS and JS now load only on pages that use the [timeline] shortcode. * Improvement: activation and deactivation hooks flush rewrite rules so CPT slugs work immediately. * Improvement: added uninstall.php to clean up plugin meta keys and transients on deletion. * Improvement: meta fields registered via register_post_meta() for REST API and block editor access. * Improvement: shortcode output cached with transients; cache busts automatically on save or delete. * Improvement: recursion guard prevents infinite loop if [timeline] appears in an entry’s content. * Improvement: new heading shortcode attribute (h2–h6) for correct document outline control. * Improvement: timeline wrapper gets role=”region” and aria-label; marker gets aria-hidden; articles get aria-label. * Improvement: admin notices shown when date/year fields are silently cleared by validation. * Improvement: featured image (thumbnail) added to CPT supports. * Improvement: menu_position changed from 5 (conflicts with Posts) to 20. * Improvement: generated languages/effortless-timeline-posts.pot for translators. #### 1.0.13 * Security: validate year_only as integer clamped to 1900–2100 (server-side). * Security: reject full_date/end_date that don’t match YYYY-MM-DD format. * Fix: format_date() returns empty string instead of “January 1, 1970” for invalid dates. * Fix: correct phpcs:ignore sniff name on virtual stylesheet handle. #### 1.0.12 * Fix: allowlist `_date_type` values to prevent arbitrary meta storage. * Fix: guard `strtotime()` return value before writing timestamp/year meta. * Fix: apply category filter before limit so `limit` counts filtered results. * Fix: admin sort direction now respects the URL `order` parameter. * Fix: shortcode output wrapped in `.timeline-dotcom` container (CSS max-width was broken). * Fix: prime post meta cache before loop (single DB query instead of N×6). * Fix: load plugin textdomain so translations work. * Fix: move meta box inline CSS and JS to properly enqueued handles. * Fix: use `ETP_VERSION` constant for asset versioning. #### 1.0.11 * Code: fix all PHPCS WordPress standard violations (tabs, alignment, short ternary, globals, comment style). #### 1.0.10 * Initial release. ## Meta * Version **1.0.32** * Last updated **10 Stonnen ago** * Active installations **Fewer than 10** * WordPress version ** 5.0 or higher ** * Tested up to **7.0** * PHP version ** 7.0 or higher ** * Language * [English (US)](https://wordpress.org/plugins/effortless-timeline-posts/) * Tags * [chronology](https://ltz.wordpress.org/plugins/tags/chronology/)[custom post type](https://ltz.wordpress.org/plugins/tags/custom-post-type/) [history](https://ltz.wordpress.org/plugins/tags/history/)[shortcode](https://ltz.wordpress.org/plugins/tags/shortcode/) [timeline](https://ltz.wordpress.org/plugins/tags/timeline/) * [Advanced View](https://ltz.wordpress.org/plugins/effortless-timeline-posts/advanced/) ## Ratings No reviews have been submitted yet.
