I've started the process of making Xenapi Admin Tools XCP 1.6 compliant. I haven't found too many things I've had to change but XCP referrs to a few parameters differently.
For instance the software-version map parameter has changed the product_brand item to platform_name. The item product_version has been changed to platform_version.
|XCP 1.1||XCP 1.6|
Neither of these changes are major and I believe they were made to make XCP more compatible with Xenserver (or at least bring their code into sync) but my lshosts command would bring up nothing for both of those columns. This has been fixed and backwards compatibility has been maintained with XCP 1.1.
