and Arbee's post on his blog is about the fact that (due to some uninitialized variables in the source) with 0.146 chdman slightly different compression could have been achieved even with the same settings on different OSes or in different runs on Windows. Now this is fixed, and everyone should get the same result if they use the same compression
