Martin Rees caught another bug in PHPEnkoder, which was making it difficult to edit posts with comments containing e-mails. This problem has been solved by turning off the enkoder filters when displaying administrative panels.
In addition to the bugfix, there are two improvements. First, the internal enkoding system will choose names that are more likely to be unique. Second, I’ve added a shortcode, enkode. You can use it to manually enkode an arbitrary stretch of text, like so: [enkode]this will be enkoded[/enkode].
