Once you are familiar with the documented platform features, review these new or changed features for native client Object API development.
The iOS default device support has changed from messaging-based to replication-based synchronization. Replication-based applications use the synchronization channel to keep data synchronized between Unwired Server and the client. This puts iOS synchronization on a par with Android, BlackBerry, Windows, and Windows Mobile. In 2.1 ESD #3, iOS messaging-based synchronization support is deprecated.
The Code Generation wizard now uses replication-based synchronization by default; the messaging-based option is still available. The messaging channel is now mainly used for device-side notifications in DOE-based applications.
Existing message-based iOS applications will continue to be supported after updating to Sybase Unwired Platform 2.1 ESD #3, but new features will not be available. Sybase recommends that you migrate existing message-based iOS applications to replication-based synchronization to take full advantage of new features.
Additional password policy control has been added to the DataVault, making it easier to populate the password policy and enforce enterprise password policies in device applications. A new DataVault API enables you to work with password policy settings, check for default passwords, change password, delete data from the datavault, and iterate through data.
