It took about four months but I finally got a review by phpBB’s extension team of my Digest extension version 3.0.5. They are requesting some pretty extensive changes so I’ll be in coding mode for a while but it’s good to have a review. No one gets approved on the first time through so I’m hoping the second time is the charm.
There may be an issue when deinstalling digests. I am analyzing that and will post a correction when I figure out what the issue is. If you need to manually deinstall digests and it doesn’t work, use these instructions.
