202616 releases

  1. Send Emails with Mandrill 1.6.7Latest

    • Fixed the Template dropdown on the settings page so the selected template name displays correctly instead of appearing blank (thanks Saskia Bouten)
    • Removed the duplicate “Tested up to” field from the main plugin file header; Plugin Check now requires it only in the readme

  2. Send Emails with Mandrill 1.6.6

    • Escaped output in the reports dashboard chart script, as flagged by Plugin Check (no visible change)
    • Requires at least WordPress 5.9, since the plugin already requires PHP 8.1
    • Developer-only: added continuous integration via the shared test harness and Dependabot for GitHub Actions (no effect on the plugin)

  3. Send Emails with Mandrill 1.6.5

    • The WooCommerce line-break fix now applies only to emails sent by WooCommerce, so other emails on WooCommerce sites keep their line breaks (GitHub #82, #84)
    • Recipients that Mandrill rejects (unsubscribed, spam complaint, bounced or invalid) no longer receive the email through the fallback mailer
    • New behavior: if Mandrill rejects every recipient, wp_mail() now returns false and fires the wp_mail_failed action with the rejection reasons instead of falling back to the native mailer
    • Disabling reports now stops the background stats API calls and hides the dashboard widget

  4. Send Emails with Mandrill 1.6.4

    • Fixed Cc: headers being dropped; CC recipients are now passed through to Mandrill (GitHub #46)
    • The wp_mail filter now passes the email body as ‘message’ again (the ‘html’ key is kept for compatibility), which fixes mail-logging plugins; a filter that returns a non-array value no longer causes a crash
    • Mandrill API requests now verify SSL certificates, and stats/admin calls use a shorter 15-second timeout so wp-admin no longer hangs when Mandrill is slow (sending keeps the longer timeout). Added a new mandrill_http_request_args filter to adjust request arguments
    • Error logs now include the actual error message from Mandrill or WordPress instead of an empty message (GitHub #90)
    • Mandrill API errors no longer crash the dashboard widget, reports and settings pages
    • Custom X-* headers are no longer dropped when they aren’t written in lowercase

  5. Send Emails with Mandrill 1.6.3

    • Fixed wp_mail() returning null instead of a boolean on the native mail fallback path, which caused a TypeError in WooCommerce 10.9+ checkout (GitHub #152)
    • wp_mail_native() now returns the native mailer’s actual result instead of discarding it
    • Caught exceptions thrown by the native mailer so they can no longer escape wp_mail() uncaught
    • Updated “Tested up to” to 7.1

  6. Send Emails with Mandrill 1.6.2

    • Added ABSPATH checks to how-tos.php, lib/reviewNotice.class.php, lib/pluginActivation.class.php, stats.php
    • Fixed missing text domain in bare (), esc_html(), esc_attr_e() calls in wpMandrill.class.php
    • Fixed text domain mismatch in how-tos.php (wpmandrill-how-tos -> send-emails-with-mandrill)
    • Replaced heredoc syntax with standard string/ob_start() in wpMandrill.class.php and how-tos.php
    • Updated “Tested up to” to 6.9
