You can find the latest release in the Assets list below.
To use it, download the zip file as-is without extracting. Open Blender, click on Edit > Preferences, then go into the Add-ons section/tab and choose the «Install...» button. Select the downloaded file, it will get installed. And, finally, enable the checkbox. Done.
You can now import and export Eurocom files from the File > Import and File > Export menus. Have fun. ¯\_(ツ)_/¯
