Parts that no longer exist in latest version will never be fetched

[nununo]

The part list is obtained based on the latest version. This means that a method existed in the past and was deleted, it will never be picked.

The part list must be complemented with lists from older versions.

Implementing this is probably very complex because standard FMs are being used to get the part lists and these based their results in the active version. I'll have to investigate.
