Build 4.5.0.62 of xlsgen improves the compatibility of xlsgen with Office 365 updates by making sure to preserve new namespaces that may be included in files, even those who will exist only in the future.

The previous build, 4.5.0.61, tackled a missing revision namespace that was included after Excel 2016 shipped, during one of the many Office 365 updates. That was the needed fix, but the build in question fixed the preservation of this very namespace, not all namespaces that may appear in the future.

Preserving future namespaces automatically is what build 4.5.0.62 by making sure that any part of the file written by xlsgen rewrites any namespace that may be declared when opening an existing file, regardless the version of Excel used to create it.
