h3. Important changes affecting 2.x user
# If empty value is specified for a prompted variable, the variable will get value of _null_. In 2.x, the default value will be used when prompted value is left empty.
# View log by step is not possible for migrated builds.
# Executed steps should be referenced by step path instead of step name. Refer to _getStep()_ method of the _steps_ object in scripting help for details.
# RESTful API is not compatible with 2.x. Existing programs needs to be changed to use the [new API|RESTful API] in order to interact with 3.x server.
# QuickBuild tray monitor needs to be reinstalled in order to interact with 3.x server.
# The method _isScheduled()_ of configuration object is now removed. Call _request.scheduled_ instead to check for scheduled build.
# Builds can not be moved from one configuration to another; otherwise, change and issue comparison will not be accurate.
# To build in a future time, define a variable prompting for date or time input, and specify pre-queue script as below:
{code}
request.setRequestDate(vars.get("name_of_the_date_var").asDate())
