This should be the last of the rapid releases for a while.  The 1.3 release addresses most if not all of the known issues and feature requests that were reported to me.  I also added a few new features.  The plugin can be downloaded at the WordPress Plugins Page.  Enjoy!

Changelog:

• Expiration date is now retained across all post status changes
• Modified date/time format options for shortcode postexpirator tag
• Added the ability to add text automatically to the post footer if expiration date is set

There are currently 3 valid attributes that can be used with the shortcode:

• dateformat – overrides the default date setting
• timeformat – overrides the default time setting
• type – full, date or time – defaults to full

For more information on the date/time format see the PHP Date Function.

The post footer text has 3 variables which can be used that will be replaced with the post expiration date/time.  The date and time format defaults will be used.  The options are:

• EXPIRATIONFULL
• EXPIRATIONDATE
• EXPIRATIONTIME

As always, please report any problems!

Changes in version 1.2:

• Changed wording from "Expiration Date" to "Post Expirator" and moved the configuration options to the "Settings" tab.
• Added shortcode tag to display the post expiration date within the post
• Added new setting for the default format
• Fixed bug where expiration date was removed when a post was auto saved

It can be downloaded at the WordPress Plugins Page.  Enjoy!
