Version 11.4.0

• Added the "Resource Pool File" attribute to ProjectProperties, which represents the full path of the resource pool used by an MPP file. This attribute is accessible via the getResourcePoolFile and setResourcePoolFile methods.
• Added the getResourcePoolObject method to allow the resource pool file to be located and read
• Added support for reading the task attribute Subproject GUID from MPP files. This attribute can be accessed via the getSubprojectGUID and setSubprojectGUID methods.
• Added support for the task attribute "External Project". When this attribute is true it indicates that the task represents a subproject. The attribute is accessed via the getExternalProject and setExternalProject methods.
• When reading an MSPDI file with external task predecessors, MPXJ now attempts to recreate the placeholder external tasks which would be present if the equivalent MPP file was read.
• External task predecessors are now represented when writing an MSPDI file.
• Added the Task method getSubprojectObject which allows the caller to retrieve a ProjectFile instance representing the external project linked to a task.
• Added the Task method expandSubproject. For task which represent an external project, this method automatically loads the external project and attaches the tasks it contains as children of the current task. This is analogous to the behavior in Microsoft Project where a subproject is expanded to reveal the tasks it contains.
• Added the ProjectFile method expandSubprojects which identifies any tasks in the project which represent an external project and expands them, linking the tasks from the external project as children of the task in the parent project. Note that the method works recursively so multiple levels of external tasks will be expanded.
• Updated to ensure that the internal_name attribute of a UserdefinedField is generated if not present.
• Updated to avoid an exception when reading notebook topics from PMXML files.
• Marked the Task method setSubprojectName as deprecated. Use the setSubProjectFile method instead.
• Marked the Task method getSubprojectName as deprecated. Use getSubprojectFile instead.
• Marked the Task method setExternalTaskProject as deprecated. Use the setSubprojectFile method instead.
• Marked the Task method getExternalTaskProject as deprecated. Use the getSubprojectFile method instead.
• Marked the ProjectFile method getSubProjects as deprecated. Use the subproject attributes on individual tasks instead.
• Marked the Task methods getSubProject and setSubProject as deprecated. Use the subproject attributes instead.

• Add method to allow an expense item's category unique ID to be retrieved.
• Added WorkContour.isDefault() method to allow "built in" resouce curves/work contours to be distinguished from user defined curves.
• Updated to retrieve the project's start date from Phoenix PPX files (Contributed by Rohit Sinha).
• Provide access to notebook topics from P6 schedules via the ProjectFile.getNotesTopics() method.
• Capture unique ID of Activity and WBS notes from P6 schedules.
• Improve the calculation used to determine At Completion Duration of activities when reading XER files and P6 databases.
• Improve representation of certain duration values written to MSPDI files.
• Improve accuracy of certain work calculations where the specified time period does not start with a working day.
• Fix an issue which caused negative timephased work values to be generated when reading certain MPP files.
• Fix an issue reading XER files where the critical_drtn_hr_cnt field is expressed a decimal rather than an integer.
• Fix an issue populating the WBS attribute for activities read from certain XER files.

Version 11.2.0

• The project property Critical Slack Limit is now represented as a Duration rather than as an Integer. (Potentially breaking change if you were using this property directly).
• TaskType is now a simple enum with all Microsoft Project specific functionality moved into TaskTypeHelper. (Potentially breaking change if you were using the TaskType methods getInstance or getValue in your code)
• When reading the task type from P6 schedule the mapping to the MPXJ TaskType enum has been updated to more closely match P6. The main changes are that the P6 type "Fixed Units" now maps to TaskType.FIXED_WORK and the "Fixed Duration & Units" type now maps to a new enumeration value TaskType.FIXED_DURATION_AND_UNITS.
• Added support for reading project calendar exceptions from Phoenix schedules (based on a contribution by Rohit Sinha).
• The Resource attribute Active now defaults to true if the schedule being read doesn't support or contain a value for this attribute.
• Add suport for reading and writing the Resource's Active flag for P6 schedules.

Version 11.0.0

• User defined fields read from P6, Asta and GanttProject schedules are now represented by instances of UserDefinedField. They will no longer be mapped to custom field instances.
• Enterprise Custom Fields read from MPP and MSPDI files are now represented by instances of UserDefinedField.
• When writing MSPDI files, UserDefinedField instances which were originally read from enterprise custom fields will be written to the MSPDI file as enterprise custom fields.
• When writing MSPDI files, UserDefinedField instances which were from applications other than Microsoft Project will automatically be mapped to available custom fields.
• When writing MPX files, UserDefinedField instances will automatically be mapped to available custom fields.
• The UserDefinedField type implements the FieldType interface and so can be used with the FieldContainer get and set methods to work with the contents of the user defined fields.
• The ProjectFile.getUserDefinedFields() method has been added to provide access to all user defined fields defined in the project.
• The CustomFieldContainer returned by ProjectFile.getCustomFields() will contain entries for all UserDefinedField instances.
• The various getFieldTypeByAlias and getFieldByAlias methods will retrieve user defined fields by name.
• Added the convenience method ProjectFile.getPopulatedFields() to retrieve details of all populated fields across the project. This avoids the caller having to individually retrieve the populated fields from the tasks container, resource container and so on.
• Updated the getPopulatedFields methods to return a Set of FieldType rather than a Set of TaskField, ResourceField etc.
• The various getPopulatedFields methods will include instances of UserDefinedField in the returned collection if relevant.
• All ENTERPRISE_CUSTOM_FIELDn values have been removed from the TaskField, ResourceField, AssignmentField and ProjectField enumerations.
