See https://github.com/bruderstein/npp-plugins-x64 for the management of the x64 plugin list. You could contribute, if you want. A template which contains the x86 export is at https://github.com/bruderstein/npp-plugins-x64/blob/master/plugins/plugins_template.xml.
Also the x86 version (management therefore is at https://npppm.bruderste.in/plugins/edit/xml-tools) is not yet at the latest available version 2.4.9.2, but still at 2.4.8.
