Default versions of the plugins downloaded

[Balasubramanian, Ravi Shankar]

Hi all, 
When we dont specify the version of a plugin to be downloaded in our
pom, does maven default to the latest version of the plugin that is
available ? Precisely, i am using the maven surefire plugin in my
projects and want to know if the latest will be downloaded if i dont
specify the version anywhere. 
 
Regards,
Ravi
