#' Retrieve OpenSSH (non-portable) Version Release History

#'
|
|
#' Reads <https://www.openssh.com/releasenotes.html> to build a data frame of
|
|
#' OpenSSH (non-portable) version release numbers and dates with semantic version
|
|
#' strings parsed and separate fields added. The data frame is also arranged in
|
|
#' order from lowest version to latest version and the `vers` column is an
|
|
#' ordered factor.
