It would be really polite if there were an issue or bug that required 
discussion if that could be started on a new topic rather the "ANNOUNCE" topic.

Asking for a friend. :)

John,

The PowerShell's System.Version object supports the form of:

   Major . Minor . Build . Revision

The cast maps the missing elements to -1.
|
For example:

PS C:\Users\sherlock> [version]"1.0"

Major  Minor  Build  Revision
-----  -----  -----  --------
1      0      -1     -1


The sort implemented is an appropriate multi-level numeric order: Major, 
then Minor, then Build, and finally Revision.


If you really want to select the gnucash folder with the greatest 
version suffix in bundle-mingw64.ps1 (assuming there is such a folder), 
the following should suffice:

$gnucash = get-childitem -path $target_dir\build | sort-object { 
[Version] $(if ($_.Name -match "^gnucash-([0-9\.]+)$") { $matches[1] } 
else { "0.0.0.0" }) } | select-object -last 1


You may want to add some logic in bundle-mingw64.ps1 to verify the 
package version subsequently derived from the config.h contained within 
the selected folder is a match.


Regards,

Sherlock
