removed from scan subcmd.

		[-containers-only]	
		[-libs-only]	
		[-wordpress-only]	

removed from report subcmd.

		[-wp-ignore-inactive]	

The format of config.toml has been changed.

before

[servers]
[servers.foo]
host = "192.168.100.1"
user = "kanbe"
keyPath = "/home/ubuntu/.ssh/id_rsa"

[servers.foo.wordpress]
osUser = "kusanagi"
docRoot = "/home/kusanagi/yokota/DocumentRoot/"
cmdPath = "/usr/local/bin/wp"
wpVulnDBToken = "TOKEN"
IgnoreInactive = false

after

[wpscan]
token = "Token"
detectInactive = false

[servers]
[servers.foo]
host = "192.168.100.1"
user = "kanbe"
keyPath = "/home/ubuntu/.ssh/id_rsa"
scanModules = ["ospkg", "wordpress", "lockfile", "port"]
containersOnly = false

[servers.foo.wordpress]
osUser = "kusanagi"
docRoot = "/home/kusanagi/yokota/DocumentRoot/"
cmdPath = "/usr/local/bin/wp"

scanMode

The following values can be specified for scanMode.
If omitted, it is equivalent to specifying all.

scanModules = ["ospkg", "wordpress", "lockfile", "port"].

For example, if you want to detect only wordPress vulnerabilities, specify the following.

scanModules = ["wordpress"]

if you want to detect vulnerabilities in OS packages and listening ports, specify the following

scanModules = ["ospkg", "port"]

If you want to specify a lockfile and scan only libraries, specify the following.

[servers.localgem]
type = "pseudo"
lockfiles = [
  "/home/ubuntu/work/redmine/Gemfile.lock"
]

If scanModules omitted, it will have the same meaning as scanModules = ["ospkg", "wordpress", "lockfile", "port"].
But since type="pseudo" in the above example, only the detection of lockfile is executed.
