Whats with old HH file formats in newer PT versions?

[el_hombre]

Some pokerrooms changed the composition of their HH files during the time. Some very early HH types where supported by earlier PT versions.
I am a user who likes to have a total oversight over his poker career, so i am very interested in PTs policy about supporting obsolete HH formats?
Will you at least support all formats you allready had supported or do i have to reckon that someday, with a newer version of PT, my old statistics wil be gone forever, because PT will not be able to import the corresponding HHs?

Anything we import now we will continue to import in the PT3 line. Anything that PT2 imported and PT3 does not yet import if you have hand histories to provide us with (via the support system), we will add support, but we have not been able to acquire certain hand histories necessary in order to add support for all possible types of sites.
