• Added BBCode parsing to new Steam chat messages
• Added ability to interact with a GC

Nearly a year in the making, v4 is now available! This release includes many breaking changes, so please carefully read over these release notes.

Breaking

• Now requires node 8 (up from node 4)
• Removed dependency on steam-client
  • Removed ability to specify a custom steam-client. Instead, that functionality is built in directly.
    • Local address binding and proxying are now options
  • Removed the Steam static property
  • Removed the client instance property
• Removed deprecated methods:
  • disableTwoFactor; non-functional, use steamcommunity instead
  • generateAuthCode; use steam-totp instead
  • requestPasswordChangeEmail; non-functional
  • changePassword; non-functional
  • createAccount; non-functional
  • changeEmail; non-functional
• server_time in enableTwoFactor callback data is now a number instead of a string (not a Date as that would break the JSON-stringifyable property of the response)
• Callbacks now have err as their first argument
  • enableTwoFactor
  • requestValidationEmail (changed from eresult)
  • getSteamGuardDetails
  • getCredentialChangeTimes
  • getAuthSecret

  • getServerIPsBySteamID
• promptSteamGuardCode option has been removed
  • Prompting for Steam Guard code from stdin now happens only if no steamGuard listeners have been attached
• parseAppTicket now has an optional second boolean parameter. If omitted or false, the function will return null if the ticket is missing a signature (or it's invalid).
• Extraneous properties have been removed from parseEncryptedAppTicket's output, including isValid and ownershipTicketExpires.
• last_seen_online is now a Date object in the user event
• The behavior of downloadFile's callback and the EventEmitter it returns has changed
  • See the docs
