• Fix an issue that could result in messages reaching guest users. This can happen when:
  • a message is sent to a team using the option to send to team members via chat, and the target team contains guest users, or
  • a message is sent to a group, and the group contains guest users, or
  • the Global app setup policy is used to install Company Communicator to all users. (The global setup policy now installs apps to guest users.)
• Fix bug with the author app interface in dark and high-contrast themes
• Resolve potential out of memory errors when sending messages to large numbers of users
• Upgrade NPM packages

See Excluding guest users from messages for steps to remove guest users from the existing users list.
