NOTE: SCROLL DOWN TO THE MOST RECENT POST BELOW FOR THE LATEST UPDATES!!!


After much community contribution, the v1.5.5. release is ready. Thanks to everybody for the feedback and help with testing and coding.

Download available here: http://sourceforge.net/projects/zencart/files/

Minimum Requirements
Zen Cart v1.5.5 requires a minimum of the following:
  • Zen Cart v1.5.5 is compatible with PHP 5.2.10 through PHP 7.1, and MySQL 5.1 thru 5.7
    (Note: PHP versions older than 5.6 are deprecated and no longer supported by PHP ... You REALLY should be using PHP 5.6 as a minimum, for both security and speed benefits.)
  • MySQL 5.1 - 5.7
  • Apache 2.2 - 2.4
  • Apache configured with AllowOverride set to either 'All' or at least both 'Limit' and 'Indexes' parameters, and preferably the 'Options' parameter as well.
  • PHP configured to support CURL with OpenSSL
  • Server's CURL and OpenSSL configured to use the latest modern TLS capabilities (particularly TLS 1.2 is quickly becoming mandatory)

While Zen Cart can run on Windows/IIS servers, Linux/Apache servers are recommended for best results, superior performance, and easier use by shopowners.

UPGRADE NOTES

How To Upgrade A Zen Cart Site
The way DrByte does upgrades is described in this blog post: http://www.zen-cart.com/entry.php?3-...d-of-upgrading

Important Note about CONFIGURE.PHP file changes for v155!

The contents of configure.php have changed (to be simplified) ... and they're MUCH SMALLER now!
The dist-configure.php shows the simplified contents, and zc_install will generate the leaner files (when doing fresh installs).
Also, zc_install will upgrade your configure.php files to the new format as long as the files are writable by your server's PHP.


A NOTE ABOUT THE NEW TEMPLATE

While Zen Cart(R) v1.5.5 contains a newer "responsive_classic" template, we STRONGLY recommend that upgraders first upgrade the site using everything (including template_default) except the responsive_classic template contents.

Then once the upgraded site is working properly you can consider what changes you might want to make to your own active template.

(Important notes about template_default are shown below)

AGAIN: The responsive_classic template should NOT be implemented immediately as part of an upgrade; it should be a separate step ... if it is even used at all. IT IS NOT NECESSARY TO USE responsive_classic ON YOUR EXISTING SITE, AND YOU SHOULD UPGRADE THE REST OF YOUR SITE FIRST BEFORE ATTEMPTING TO CONVERT/ADAPT IT TO YOUR USE.


Notes about changes to TEMPLATE_DEFAULT

UPGRADERS SHOULD BE SURE TO UPDATE BOTH template_default AND YOUR CUSTOM TEMPLATE as described here:

In Zen Cart the template_default directory contains the master copy of all storefront page templates. The normal procedure for customizing template files for use in your own personalized template is to make a copy of the corresponding file from template_default, put it into your own template folder (and matching folder structure), and make your customizations in that copy of the file. This way the only files you need in your personalized template folder are those that you have altered in some way from template_default.

With that explained, it is important that whenever you upgrade your site, you should also inspect ALL the template_default files to determine which changes in those files need to be replicated in your customized files.

Often a tool like Beyond Compare or Araxis Merge or GnuDiff can be helpful for this. The process is simple: compare the template_default directory files from your *old* version against the template_default files in the *new) version, and use those results as a reference to copy those updated changes into each of the files you've customized in your custom/personalized template in your store.
Then, and only after you've done all those comparisons and updated your customized files in your custom template folder, you will copy the template_default files from the new version into the template_default directory of your store. This way you'll be left with updated personalized files *and* updated template_default files.


Changes in template_default for v1.5.5

The template_default files previously had a lot of old <table> markup to specify widths, cell borders and padding and spacing. These have been removed in v1.5.5 and relevant styles added to the bottom of the main stylesheet.css file. You will want to add the updated CSS parts to your own stylesheet if your custom template still uses those tables. (A few 3rd-party templates have aggressively ripped out various tables and may not be affected by this change.)

A few CSS changes were made in template_default to change IDs of repeating elements to be classes instead. Of note #cartDisplay is now .cartDisplay, and #cartImage is .cartImage

NOTE:

Many people have asked about the "missing ?> at the end of some PHP files".
This is INTENTIONAL, and explained here: http://www.zen-cart.com/content.php?271
It is NOT an error in the files or the download.



Also a huge thanks to Anne at Picaflor-Azul for preparing the new Responsive Classic template and for Raymond Barbour of zcadditions.com for the DIY responsive components driving it.
