MailPoet Newsletters (version 2)

Fork of legacy version of MailPoet WordPress plugin.

Requirements

• WordPress 3.5 or newer

Changes

Note: All changes can be reviewed by comparing legacy branch to master branch (forked version with updates).

API

• There is no default filter hooked to the wysija_send_ok hook, thus default value passed to wysija_send_ok filter is now true instead of false.
• Following (deprecated) actions have been removed: wysija_send_test_editor and wysija_manual_send.

Fixes

• Compatibility with PHP 7.2 and newer has been improved
• The code has been made more defensive in several places in order to not trigger PHP notices about undefined array keys etc.

Tweaks

• All functionality related to 2000 subscribers limit has been removed, including following actions:
  • wysija_check_total_subscribers
  • wysija_remove_action_check_total_subscribers
• Blacklist functionality (introduced in upstream version 2.12) has been removed
• If Git Updater is installed, this plugin can only be updated from GitHub, never from WordPress.org Plugin Directory.
