A beta release of the next version of Clippings for Thunderbird is now available! It is compatible with the new 
Thunderbird 68 beta release.
Clippings for Thunderbird 5.7 beta 1 is intended for testers and early adopters who want the 
latest and greatest, and are willing to tolerate a few bugs. 
What's New:
- Compatible with Thunderbird 68
- You can now choose how you want the date or time to be formatted for
 the $[DATE] and $[TIME] placeholders; for example, the date with the 
day of the week included, or the time given in the 24-hour clock. To add
 a formatted date or time placeholder to your clipping, open Clippings 
Manager, turn on the Placeholder Toolbar (Tools → Show/Hide menu), then 
from the toolbar, click Presets and select Formatted Date/Time
- Special characters (question mark, parentheses, quotation marks, asterisk, common
	    currency symbols, etc.) can now be used in default values for placeholders. Note that the
	    pipe symbol (|), curly braces ({}) and square brackets([]) cannot be used.
