There was a bug discovered that occurs with extremely low probability when writing to or reading from files. The message you see is warning about places in the code where this bug needs a proper fix (there is currently a stop-gap measure in place, a proper fix will be a lot of work).
So there actually was a problem with the old version, it was just unknown. Now at least there's a warning.
