// Changelog
//
//
// 5.30 - removed email check for registered users in index.php
// - for unsubscribed users names was wrong in list.
// subscribers.php
// - wrote new functions_mail.php to run better. It now saves an
// archive of the text email also. This requires an upgrade.
// edit also pninit.php, pntables.php
// - since we are archiving the text mailers, we might as well make
// them viewable. edit archives.php, functions.php
// I decided not to make this an option for users
// - added option to send all mailers out to each user one at a time
// rather than in bulk. added global.php lang _READYTOSENDSINGLES,
// _OUTOF, _EMAILSSENT, _CONTITOSENDHTML, _CONTITOSENDTEXT
// - Daniel Luttermann updated deu lang files
// - placed english definitions in other global lang files.
//

// - now you can update your plugins with one click. very exciting.
// edit modules.php
// - new feature for all plugins. set initial values with
// modversion[mod_data]. This is really for future plugins so

// - unregistered subscribers can now retrieve their username by
// entering their email address. index.php, global.php

// - probably made a few other minor changes but I regretfully forgot
// to update this changelog when I made them. I don't think any
// other files have been altered.
//
// 5.70 - you must now generate the newsletter before sending it. This way
// you can see it before it goes out. Also, you can generate
// letters without having to email them. The main reason for doing
// this is to speed up the send times for mailing. I think generating
// the letter was making the email appear to take much longer.
// also, nothing wrong with more control :). changed functions_mail.php,
// eng language file
// - remove the "*(r) indicates mailer read by subscriber" as it was
// creating false readings that just makes things confusing. changed
// subscribers.php

// out before refreshing the page. changed vars.php, pninit.php,
// pntables.php, functions.php, admin.php

// module folder and users will have a link in their account area to
// access the pnTresMailer user page.

// username. Turn it on in SETTINGS and add <!-- [USERNAME] -->

// functions_mail.php, archives.php and added to the end language file
// - removed all upgrade support for versions prior to 5.34
// you have to upgrade to that version before this version
// - IMPORTANT!! changed the template inserts. what used to be inserted
// with [ISSUE] is now <!-- [ISSUE] -->. This was done for those
// using the peronalized options. this way these tags aren't
// seen by the user if they don't get replaced.

// that turns it on or off and will display a red (r) when
// a subscribers opens the last newsletter sent. must be sent
// individually or single and not bulk.
// - to use the tracker, turn it on and add the tag: <!-- [TRACKER -->
// Add the tag somewhre in the header, footer, or any other
// part of the body of the newsletter.
// - found error in functions_mail where sending single emails
// was sending bad data.
//
