NOTE FOR UPGRADERS

If you are using PayPal, you'll need to REMOVE and re-INSTALL the paypal payment module in Admin->Modules->Payment, after upgrading.

If you need a reference for paypal settings, see the Zen Cart + Paypal Setup document in the /docs folder, or refer to the paypal site for technical documentation.

CHANGELOG - List of Changed Files

For a list of files that have been changed since v1.2.6, see the changelog-v1-3-0.html

Whats New ...

The following are the major NEW ADDITIONS to v1.3.0d:

Template System Cleanup

• All catalog pages are XHTML-Compliant (XHTML Transitional)
  
• Template layouts have been redesigned with customer-usability in mind
  
• Business Logic has been removed from templates, leaving only display logic where needed.
  This means template files are smaller, tidier, easier to follow, and easier to customize.
  To accomplish this, many components have been refactored as modules.
  
• Enhancements
  - breadcrumbs can be enabled/disabled via admin switch
  
• New button-set for default/demo templates

Added Features

• New Unlimited EZ-Pages
  Inspired by sunrom's "Unlimited Information Pages" contribution, EZPages has been integrated into the core code, and enhanced to enable use in header, footer, or even sidebox.
  It's even possible to have more than one sidebox, with a few coding alterations.
  Enabling/disabling placement and sort order is all handled from the admin interface under the "Tools->EZ-Pages" menu.
  You can even group pages into chapters, and also specify a TOC (Table of Contents) for a certain chapter, which also allows a previous/next navigation through that chapter's pages.
  Also allows for SSL mode and "open in new window" mode on a per-page basis.
  Currently only supports a single language.
  
• CSS Stylesheet control on a per-page basis
  Inspired by Juxi Joza's contribution, you can now use a different stylesheet for each page of your site, including per-product or per-manufacturer or per-language delineations.
  Also added printer-friendly stylesheet support (css/print*.css files)
  See the readme_css_system.html for more information.
  
• PHPMailer
  The email subsystem has been replaced with the popular PHPMailer class. This will work around many limitations to the older legacy email subsystem which resulted in odd email problems with various hosting configurations and various email clients having problems reading contents.
  
• PayPal IPN updated
  Added missing code to process e-checks
  Added debug facility
  (NOTE: Requires that you "remove" and re-"install" your Paypal payment module in Admin)
  
• Site Map and 404 trapper
  Inspired by NetworkDad's contribution and langer's error404 contribution as well as suggestions/contributions by several others, the Site Map link (now in the Information sidebox) shows a navigable map of all categories and some core static pages. Great "spider food"!
  Enabling the switch to trap for "page not found" and "product not found" errors, also takes customers (and spiders) to the Site Map for alternate choices for finding their intended link.
  Sample .htaccess for "page-not-found" support can be found in the "extras" folder.
  
• PHP Minimum Version requirement is now PHP v4.3.2
  We have raised the minimum supported configuration to PHP v4.3.2 due to the number of bugs fixed to that point. Some session-handling features in 4.3.2 function much more smoothly than in versions previous to that. Specifically, Zen Cart's "recreate session" switch only functions on PHP v4.3.2 or higher. Functionally-speaking, Zen Cart "will" still operate on PHP versions as low as 4.1.2, but you run the risk of odd login/security problems and some email issues.
  If you run into problems with Zen Cart and are using a PHP version prior to v4.3.2, we suggest you strongly encourage your host to upgrade, or to move you to a server that 'is' upgraded.
  
• Notifier Subsystem
  The notifier subsystem allows you to "hook" into various cart events to alter the normal behaviour of standard activities. One possible use for this is the potential to activate a "buy one get one free" sort of feature during checkout.
  See wiki for detailed explanations and examples.
  
• Coding optimization:
  - autoloader system implemented to replace application_top. Now split out into several separate components, found in the "init_includes" folder. Any customizations to these files can be overridden by using the "override" folder.
  - javascript "modules/pages/xxxx/jscript*.js" files now supported for inclusion by reference rather than only as inline javascript sent to the browser (from "jscript*.php" files).
  - More documentation in the wiki
  
• Admin Multiple Categories Links Manager navigation enhanced
• NEW shipping modules
  - freeoptions - offers the ability to have free shipping while any of the other shipping modules are displayed. It can be based on any combination of total, items, or weight. (The older "freeshipper" was free-only, the new freeoptions allows combinations.)
  - perweightunit - allows to charge shipping based strictly on the weight of the entire order. (this could be cloned on a per-currency level if needed, etc)
• Category Metatags support added
  Now you can configure metatag information specific to individual categories.
  
• Attributes System
  - Added textarea option on TEXT attributes, defined in Option Name Manager, allowing multi-line text-input attribute fields.
  - Attribute Controller delete all Option Values to 1 Option Name with confirmation

IMPORTANT NOTES

• Please be sure to review and apply the Site Security Recommendations to your site prior to taking your shop "live". If you are uncertain about how site security applies to you, talk to your web host to ensure that you have proper measures in place.
  
• XHTML Compliance: For true XHTML compliance, you should verify that all your product descriptions are fully XHTML-compliant. Also, any custom pages you have created or modified may need to be reviewed individually for XHTML compliance.

• You may wish to go to Admin->Email Options->Allow Guest To Tell A Friend and set the option to 'false'. This will prevent non-logged-in customers from using your server to send unwanted email messages. (This is turned off by default on fresh installs. Upgraders should consider turning this off manually.)

Notes for Upgraders ... from v1.2.x to v1.3.0

• admin/includes/configure.php

  admin/includes/configure.php now contains DIR_FS_DOWNLOAD for fresh installs. Previously it was defined in admin/download_manager.php. It is advised to add this entry to your admin/includes/configure.php MANUALLY during an upgrade, as future releases may rely on this setting being set as such.
  

• meta_tags custom separators

  meta_tags.php: 'PRIMARY_SECTION', 'SECONDARY_SECTION', 'TERTIARY_SECTION' moved from modules/meta_tags.php into languages/english/meta_tags.php
  

• DEFINE PAGES

  If your active template is 'classic', then you need to BE CAREFUL to not overwrite your customized files in the /includes/languages/english/html_includes/classic/*.* area.
  NOTE: BEFORE UPGRADING, it is wise to make a backup copy of all the files/folders in: /includes/languages/english/html_includes
  

• Tell a friend

  You may wish to go to Admin->Email Options->Allow Guest To Tell A Friend and set the option to 'false'. This will prevent non-logged-in customers from using your server to send unwanted email messages. (This is turned off by default on fresh installs. Upgraders should consider turning this off manually.)

UPGRADING YOUR TEMPLATES

• upgrade your existing template by applying the new stylesheet and moving a few lines of code around; or
• the best way to have almost-tableless and much tidier template code, is to make a new template and carefully re-apply your own customizations to the new template system.

For further information on template upgrading, see the forum discussion on this topic.
