Different Wiktionaries store their data in different ways. WikDict knows this and handles the data accordingly. Unfortunately, the data structure is not fully consistent even within a single Wiktionary. Recent changes relax some assumptions made with regards to the structure of translations, which allows more translations to find their way into the public WikDict data set. The results are especially beneficial for Turkish, Russian and Bulgarian but have a noticeable effect on nearly all language pairs.
See the GitHub issue if you are interested in more technical details of this change.
