@Guenterm, version history does not mention the build numbers, neither for the Mac nor the Win releases. Too bad, but we can’t help it. Normally, build numbers are meant for development rather than for users. I guess we’ll have to live with whatever DxO does in this respect.
Differences between Mac and Win versions of DPL: The thread started by @Franky and yours contain about 40 posts each. Other posts exist, but are difficult to track. A shared document would be easier to handle.
