I'm doing openvpn client packaging for WAPT and wanted to know more about the versioning scheme of OpenVPN.
I came across the weird numbering scheme 2.6.0-I004, what is the purpose of the I (capital i) in the version number? Actually the MSI properties version is 2.6.009. After installation, the number in the Windows registry is also 2.6.009. So what is the real number? Why is there some discrepancies between the version numbers?
Moreover, on the website https://openvpn.net/community-downloads/ , the version 2.6.0-I004 is mentioned as released on the 25th of January, while it has been release on the 6th of February.
Thanks for you time
