# Introduction
MSNP11 is the tenth released version of the Mobile Status Notification Protocol.
It was introduced officially in Client Version 7.0.0777.

# Command information
It introduces the notification service commands:
* [GCF](../commands/gcf.md)
* SBS
* [UBX](../commands/ubx.md)
* [UUX](../commands/uux.md)

*No switchboard or dispatch service commands were known to be introduced in this version*

*No error codes were known to be introduced in this version*

*No commands were known to be removed in this version*

# Known changes
(from [MSNP10](msnp10.md)):
* [QRY](../commands/qry.md): Challenge response generation has been drastically overhauled.
  TODO: Write annotated source code explaning new algorithm.
* [OUT](../commands/out.md) RCT `TimeBeforeRetry` now exists.
  `TimeBeforeRetry` is a numerical value in minutes that specifies the amount
  of time in minutes the client should wait before reconnecting.
* All `ABCHMigrated` changes are now the default - `ABCHMigrated: 0` is Undefined Behaviour from now on.
* [ADC](../commands/adc.md): Now supports a telephone address (`tel:`) for `N=`.
* Official Client: Feature blocks are implemented using the [GCF](../commands/gcf.md) command
  to download `Shields.xml`. For more information read the [Shields Configuration Data](../files/shields.md) article.
* Official Client: WebMessenger now canonically exists, the [Client Capability](../files/client_capabilities.md)
  flag `512` (`0x200` mask) is set for clients online via this method.
* Official Client: Notifications ([NOT](../commands/not.md) commands) with encoded
  [`<NotificationData>`](../files/notification.md) sub-documents are supported for spaces (blogs).
* Official Client: Messenger Config requests now support regional arguments via SOAP.
* Official Client: [OUT](../commands/out.md) SSD is actually implemented now.
* Official Client: Error code 913 is handled again after being removed last version. Why?
