Updating WordPress Plugin Updating Tested up to Tag

Sometimes we just need to test and update the Tested up to WordPress version tag fro our plugins in the open repositories.

This can be done using SVN directly.

1. Check out the existing version.
svn co https://plugins.svn.wordpress.org/future-draft/

2. Update the tag in README.txt

3. Commit
svn ci -m 'update to WordPress version 4.8.2'
