Features

• Compatibility with Joomla 3.7
• CSV Import: introduce auto-detection of CSV file format

Improvements

• Diagnosis section prints DB structure info
• Remove unneeded "Show User description" setting
• Do not have the mailing list name in attachment folder structure as a subfolder
• Optimization for high traffic (large queue) installations that have send limits: alternate between sending out mails and digests
• CSV Import: check on PHP's max_input_vars setting to detect when too much entries would be present to inform the user
• Updated Dutch translation (thanks Jean-Paul!)
• Updated French translation (thanks Gilles!)

Fixes

• Send welcome/goodbye messages when admin subscribes/unsubscribes user to list in Joomla user manager
• When emails are resend/reset, put moderation status to "do not moderate" in order to get the email going immediately (avoid double enqueue-ing)
• Store each attachment in its own subfolder to avoid naming/storing conflicts for multiple attachments having the same name
• Remove orphan entries in digests, list members and group users (when user was removed) as part of maintenance job
• Avoid deprecated messages with PHP 7
• Correct subscribe-URL generation for HTTPS pages
• Fix German translation (was unavailable in earlier version)
