I quite agree. A list of changes of the latest version on the LW update page would help me decide whether it's worth downloading:

They've introduced file hashing and dynamic resume? Yes I'll download it!

They've fixed a bug that doesn't affect me and made a couple of cosmetic changes as an excuse to push the version number up? No, I don't think I'll bother.

They should also include a full version history with the installer like in most other commercial and shareware software.

Paying Pro users have a right to be informed in detail about development of the product we are helping to finance. At the moment to get [some of] this inforamation, you have to spend a lot of time trawling through forum posts or study the Gnutella and LW developer pages (if you're a programmer, which I'm not).
