Easy Theme and Plugin Upgrades

Version Description

Enhancement: Removed the requirement for the user to select "Yes" from the drop down in order to initiate an update. This new version does not change the appearance of the upload form. Instead, it automatically creates a backup and performs an upgrade if the supplied plugin or theme already exists.
- Enhancement: If a zip backup file cannot be created, the old directory is renamed to a new name in order to still keep a backup.
- Enhancement: Updated the code to use a better way of integrating the upgrade logic. This approach should greatly reduce the potential for conflicts with other code or site configurations.
- Enhancement: The backup details now are found in the same format as the rest of the upgrade messages.

15	+ 2.0.0 - 2016-08-15 - Chris Jean
16	+ Enhancement: Removed the requirement for the user to select "Yes" from the drop down in order to initiate an update. This new version does not change the appearance of the upload form. Instead, it automatically creates a backup and performs an upgrade if the supplied plugin or theme already exists.
17	+ Enhancement: If a zip backup file cannot be created, the old directory is renamed to a new name in order to still keep a backup.
18	+ Enhancement: Updated the code to use a better way of integrating the upgrade logic. This approach should greatly reduce the potential for conflicts with other code or site configurations.
19	+ Enhancement: The backup details now are found in the same format as the rest of the upgrade messages.

21	+ Attention: Version 2.0.0 changed the functionality of the plugin. You are no longer required to select "Yes" from a drop down before the theme or plugin can be upgraded. The need for an upgrade is now detected automatically. So, if you are used to the old functionality of the plugin, do not be concerned about the absence of upgrade details on the theme and plugin upload pages. Simply upload the theme or plugin as if you were installing it, and the plugin will automatically handle upgrading as needed.
