On every page in the Define Page Editor, it just goes to this default includes/local/skip_version_check.ini. No matter which page I select. It won't let me edit any pages.

It is possible that if you're using plugins which register Observer classes, if more than one is attaching to the same notifier event, only the first one will fire when a notification is dispatched.

This is fixed by making a small code change:
https://github.com/zencart/zencart/pull/3654/files

A select few payment modules may not be fully updating order-payment comments after the order is created.

This can be fixed by making the changes shown here:
https://github.com/zencart/zencart/pull/3769/files

In v1.5.7 the display of products for 'Customers who bought this product also purchased....' at bottom of product info page may not appear.

Fix is here: https://github.com/zencart/zencart/pull/3848

In 1.5.7, when copying a product to a new one, the master category might not get set for the new category.

The fix: https://github.com/zencart/zencart/c...f8c16ffb71c42a

In v1.5.6 and v1.5.7 (before 157a) entering a password in Admin (for an Admin or to reset for a customer) was encoding any "special characters" such as < or > symbols.

The fix will be included in v157a, and can be applied manually by adding the lines shown in green here to the file mentioned:
https://github.com/zencart/zencart/c...14ecd658eb087f

All the above, and several more, have been fixed in v157a, which is now available for download.

A handful of very important bugfixes have been included in the release of v157b.
If you're using v157 or v157a, it is critical that you upgrade to v157b ASAP.

If you are using MySQL 8.0.17 or higher, you may experience issues like this:
