For example, I’m no longer doing backward compatibility retrieval on posts using the older storage formats, which, looking at older posts, means that some things are not displaying. I have been restoring the information to the posts by manually reparsing it, but I may have to release a version to do so automatically, as no one wants to go through old posts.
Fortunately, I don’t have that many, but I do need to make sure those who posted more aren’t subject to the same problem.
