This RStudio Connect patch release addresses an urgent security update and an important bug fix.
Security Update: Password Authentication
A vulnerability has been identified for customers using RStudio Connect’s built-in password authentication. Due to the risks involved, password authentication will now require the configuration setting Server.Address for operations that will send emails. If this setting is not configured an error will occur for these operations. More detailed information about the vulnerability will be released in a future post.
