13.9.0 (unreleased)

13.8.0 (2024-12-17)

• Added support for reading and writing Project Codes, Resource Codes, Role Codes and Resource Assignment Codes for Primavera P6 schedules.
• When writing PMXML files, improve handling of P6 schedules where activity code sequence numbers are missing.
• Added an experimental feature to MSPDIWriter to allow the writer to generate timephased data when none is present. Disabled by default, call the setGenerateMissingTimephasedData and pass true to enable.
• To improve consistency, the methods Task.getPrimaryResourceID() and Task.setPrimaryResourceID() have been marked as deprecated. Use the new Task.getPrimaryResourceUniqueID() and Task.setPrimaryResourceUniqueID() methods instead.
• Added the methods Task.getPrimaryResource() and Task.setPrimaryResource().
• Improved accuracy of retrieving the resource assignment GUID attribute when reading MPP files (Contributed by Fabian Schmidt).
• Improve population of Task Start and Finish attributes when reading Primavera P6 schedules.
• Marked the ActivityCodeValue.getParent() method as deprecated. Use ActivityCodeValue.getParentValue() instead.
• Marked the ActivityCodeValue.getParentUniqueID() method as deprecated. Use ActivityCodeValue.getParentValueUniqueID() instead.
• Marked the ActivityCodeValue.Builder.parent() method as deprecated. Use ActivityCodeValue.Builder.parentValue() instead.
• Marked the ActivityCodeValue.getActivityCode() method as deprecated. Use ActivityCodeValue.getParentCode() instead.

13.7.0 (2024-11-25)

• Update the MPXJ ruby gem to allow access to calendar data.
• Mark the ActivityCodeValue.getType() method as deprecated. For clarity this method has been replaced by the new ActivityCodeValue.getActivityCode() method.
• Mark the ActivityCodeValue.Builder.type() method as deprecated. For clarity this method has been replaced by the new ActivityCodeValue.Builder.activityCode() method.
• Added the Task.getActivityCodeValues() method, which returns a Map of ActivityCodeValue instances, keyed by ActivityCode.
• Marked the Task.getActivityCodes() method as deprecated. Replaced with the Task.getActivityCodeValues() method which is more clearly named, and presents the activity code values in a more flexible form.
• Added the Task.addActivityCodeValue() method.
• Marked the Task.addActivityCode() method as deprecated. Replaced with the Task.addActivityCodeValue() method which is more clearly named.
• Further improvements to retrieval of custom field values read from MPP files.
• Ensure that missing resource assignment and task start and finish dates are handled gracefully when working with calendars for manually scheduled tasks.

13.6.0 (2024-11-06)

• Added the Task.getBaselineTask() methods. For applications where a separate baseline schedule is present or a baseline has been manually added to the ProjectFile instance, these methods will allow you to access the underlying baseline task instance from the current task instance.
• Added the Activity Percent Complete attribute to the Task class. The value of this attribute will be the Duration, Physical or Units percent complete value, based on the Percent Complete Type setting. This attribute is provided as a convenience to match the Activity Percent Complete type value shown in P6.
• Improve retrieval of custom field values for certain MPP files.
• Improve handling of PMXML files with more than 11 baselines.
• Improve handling of unexpected data types when writing JSON files.

13.5.1 (2024-10-28)

• Fix CVE-2024-49771: Potential Path Traversal Vulnerability (Contributed by yyjLF and sprinkle).

13.5.0 (2024-10-17)

• Added support for reading and writing Resource Role Assignments for Primavera schedules. The Resource.getRoleAssignments() method retrieves a map representing the roles a resource is assigned to, along with the skill level for each assignment. The Resource.addRoleAssignment() and Resource.removeRoleAssignment() methods allow role assignments to be added and removed.
• Added support for the Resource Primary Role attribute, which is read from and written to Primavera schedules.
• Improve handling Boolean attributes with default values when reading XER files.
• Added the getShowStartText, getShowFinishText and getShowDurationText methods to the Task class. When working with manually scheduled tasks in Microsoft Project, users can potentially supply arbitrary text for the Start, Finish and Duration attributes. Microsoft Project still stores appropriate values for these attributes, which can be accessed in MPXJ as Start, Finish and Duration, but where the user has supplied text, these attributes are available as Start Text, Finish Text, and Duration Text. The methods added by this change allow the caller to determine which version of each attribute should be shown to the user in order to replicate what they see in Microsoft Project.

13.4.2 (2024-10-08)

• Added the ProjectCalendarDays.getCalendarHours() method to allow direct access to the ProjectCalendarHours instances for each day of the week.

13.4.1 (2024-10-07)

13.3.1 (2024-08-30)

• Handle duplicate custom field value unique IDs when reading MSPDI files.
• Handle missing remaining early start date when reading timephased data from a P6 schedule.

13.3.0 (2024-08-22)

• When reading multiple Primavera schedules from the same source, MPXJ now ensures that instances of activity code definitions, user defined field definitions, locations, units of measure, expense categories, cost accounts, work contours, and notes topics are shared across projects. This will allow you to, for example, filter tasks from multiple projects using a Location instance. Previously each project had its own independent instances for each of these types, which could not be used across multiple projects.
• When reading Powerproject schedules, ensure that the Activity ID attribute for WBS entries is populated using Powerproject's Unique Task ID attribute.
• Add support for reading timephased planned work from MPP files for manually scheduled tasks (Contributed by Fabian Schmidt).

13.2.2 (2024-08-14)

13.1.0 (2024-07-26)

• Updated to POI 5.3.0
• Add support for reading and writing timephased data for activities in P6 schedules which have a "manual" curve. (Note: MPXJ does not currently support translating timephased data between different applications, so timephased data read from an MPP file won't be written to a P6 schedule and vice versa).
• Add an attribute to the ResourceAssignment class to represent timephased planned work. This is read from/written to P6 as Budgeted Work.
• Update Phoenix schemas to ensure that cost types are represented as doubles.
• Updated to avoid reading apparently invalid resources from Project Commander files.
• Correct the Finish attribute for resource assignments when reading PMXML files.
• Improve accuracy of the RemainingDuration attribute for resource assignments when writing PMXML files.
• Improve recognition of non-working days when reading calendars certain PMXML files.
• Add support for the Resource Assignment field Remaining Units. (Note: this field defaults to the same value as Units if it is not explicitly populated).
• Ensure the Resource Assignment field Remaining Units is read from and written to P6 schedules.
• Improve handling of invalid calendar exception data when reading P6 schedules from XER files or a P6 database.
• Improve the implementation of the Unique ID sequence generator used by MPXJ to avoid issues when multiple classloaders are used.

13.0.1 (2024-07-04)

• For XER files, ignore the "null" resource when writing resource rates.
• When reading MPP files, ensure that Enterprise Custom Field Unique IDs are unique across entities.

13.0.0 (2024-06-20)

• NOTE: this is a major release containing breaking changes. When updating from a 12.x release it is recommended that you first update to the most recent 12.x release and deal with any deprecation warnings before moving to this release.
• NOTE: the original net.sf.mpxj NuGet packages are now deprecated and will be replaced by the MPXJ.Net NuGet Package in the next major MPXJ release. The net.sf.mpxj packages will continue to be maintained until then, at which point they will no longer be distributed. Please migrate your code to use MPXJ.Net at the earliest opportunity, and open an issue in the GitHUb issue tracker if you encounter problems.
• Updated to use JAXB3. Among other things this change ensures compatibility with Spring Boot 3. Note that this may be a breaking change for you if you own application uses JAXB2.
• When reading P6 schedules, the custom properties (as retrieved using ProjectProperties.getCustomProperties) will no longer contain scheduling options. These are now all available as attributes of the ProjectProperties class.
• Removed redundant setUniqueID methods from immutable objects. These previously threw UnsupportedOperationException when called.
• The ProjectEntityWithUniqueID interface no longer contains the setUniqueID method. Entities with a mutable Unique ID attribute now implement the ProjectEntityWithMutableUniqueID interface, which inherits from the ProjectEntityWithUniqueID interface.

• Marked the ProjectReader method setCharset as deprecated. Readers which support setting the Charset now implement the HasCharset interface, which includes Charset getter and setter methods.
• Implemented the UniversalProjectWriter class. This complements the UniversalProjectReader class by providing a simple way for MPXJ users to write project files without having to be concerned with details of the individual ProjectWriter classes. This is intended to replace the ProjectWriterUtility class. Note that the ProjectWriterUtility has a somewhat brittle mechanism to determine the output file format from the supplied output file name. This is not replicated by UniversalProjectWriter, users are expected to provide their own code to determine the appropriate file format.
• Marked the ProjectWriterUtility class as deprecated.

12.9.0 (2024-04-11)

• Updated UniversalProjectReader to add getProjectReaderProxy methods to allow access to the instance of the reader class which will be used to read a schedule, prior to the schedule being read. This will allow the reader to be configured, or schedule to be ignored without reading its content.
• Deprecated the ProjectReader.setProperties method. This method was originally implemented to allow settings to be passed to reader classes when using UniversalProjectReader. You can now use UniversalProjectReader.getProjectReaderProxy to achieve this.
• Add from method to all Builder classes to allow initialisation from existing objects.
• The CostAccount.Builder class now provides two notes methods to allow formatted or unformatted notes to be added to cost accounts.

• Update representation of Work Variance when writing MSPDI files to more closely match output from Microsoft Project.
• Updated to ensure that when schedules are read from XER files or P6 databases, labor and nonlabor work amounts are combined for the Actual, Remaining and Planned work attributes. This is now consistent with the existing behavior when reading PMXML files.
• Added support for new Task attributes Actual Work Labor, Actual Work Nonlabor, Remaining Work Labor, Remaining Work Nonlabor, Planned Work Labor, Planned Work Nonlabor, when reading and writing P6 schedules.
• Update default readAll method on reader classes to ensure that if the reader is unable to read any schedule data, an empty list is returned rather than a list containing null.
• Ensure that Task Start and Finish dates are both the same when reading milestones from PMXML files, and that the correct date is used depending on whether we have a Start Milestone or a Finish Milestone.

• Added new versions of the TimephasedUtility.segmentBaselineWork and segmentBaselineCost methods which take a ProjectCalendar instance as the first argument rather than a ProjectFile instance.
• Deprecated the TimephasedUtility.segmentBaselineWork and segmentBaselineCost methods which take a ProjectFile instance as the first argument.
• Added a new version of the ProjectCalendar.getDate() method which just takes a date and a duration as its arguments. This method handles both positive and negative durations.

• All P6 scheduling and leveling options which were previously made available via the ProjectProperties custom properties map are now deprecated. These properties now have individual getter and setter methods available on the ProjectProperties class. Note: this may be a breaking change if you were creating schedules from scratch, populating the custom properties map, then writing PMXML or XER files. In this case you will need to update your code, for all other use cases your code will continue to work unchanged until the next major version of MPXJ.
• Added support for reading and writing the ProjectProperties attributes Baseline Type Name, Baseline Type Unique ID, and Last Baseline Update Date for baseline projects in PMXML files.
• When reading projects from PMXML files, if the creation date attribute is not present in the file fall back to populating the ProjectProperties creation date attribute with the PMXML date added attribute.

• Added support for the WBS Code Separator attribute to ProjectProperties.
• Avoid creating duplicate ActivityCodeValue instances when reading Asta PP files.
• Added a new version of the ProjectFile.expandSubprojects method which takes a boolean argument indicating if external tasks should be removed. Passing true to this method will recreate predecessor and successor relationships using the original tasks rather than the placeholder external tasks, and will remove the external tasks.
• Marked the ProjectFile.expandSubprojects() method as deprecated, use the new version which takes a boolean argument instead.
• Ensure the ProjectProperties name attribute is set correctly when reading XER files and P6 databases.

• Implemented the ActivityCode.Builder class.
• Marked the ActivityCode constructor as deprecated, use the ActivityCode.Builder class instead.
• Only predecessor Relation instances are now stored in RelationContainer, successors are generated dynamically. You will only notice a difference if you are iterating over the RelationContainer collection directly, in which case you will only see predecessors.

12.3.0 (2023-11-07)

• Retrieve role availability data when reading a schedule from a P6 database.
• Populate the project's Name and Title attributes when exporting an MSPDI file.
• Ensure the Project ID attribute is populated when writing an XER file.
• Don't include null tasks (blank tasks) when writing an XER file.
• Strip control characters from entity names written to MSPDI files and XER files.

12.2.0 (2023-10-12)

• Add the UnitOfMeasure class to represent the unit of measure for a material resource. The unit of measure corresponds to the current "material label" attribute of a resource. The Resource.getMaterialLabel() method will now retrieve the label from the UnitOfMeasure instance associated with the resource. The Resource.setMaterialLabel() method is now deprecated, the Resource.setUnitOfMeasure() or Resource.setUnitOfMeasureUniqueID() methods should be used instead.
• Unit of measure for material resources are now read from and written to Primavera schedules.
• Improve task duration and percent completion calculation for Asta PP files.
• Improve date parsing when reading XER files written by older versions of P6.
• Added the setIgnoreErrors method to the Primavera database reader class, and MSPDI, Schedule Grid, and SDEF file reader classes. The current default behavior of ignoring data type parse errors is unchanged. Calling setIgnoreErrors(false) on one of these reader classes will ensure that an exception is raised when a data type parse error is encountered.
• Added the ProjectFile.getIgnoredErrors() method. The default behavior for MPXJ reader classes is to ignore data type parse errors. If any errors have been ignored when reading a schedule, details of these errors can be retrieved by calling the ProjectFile.getIgnoredErrors() method.
• Handle duplicate relation unique IDs when reading schedules.
• Include resource availability table in JSON output.
• Add the Resource field Default Units, and ensure this field is read and written for P6 Schedules.
• Updated the Resource attribute Max Units to ensure that this is calculated from the resource's availability table. Note that the Resource.getMaxUnits() method will return the resource's Max Units attribute for the current date. To retrieve the Max Units for a different date, use the AvailabilityTable.getEntryByDate() method.
• Marked the Resource.setMaxUnits() method as deprecated. The Max Units attribute is derived from the resource's availability table. Changes to Max Units should now be made by modifying the availability table.
• Updated the Resource attribute Available From to ensure that this is calculated from the resource's availability table. Note that the Resource.getAvailableFrom() method will return the resource's Available From attribute for the current date. To retrieve the Available From attribute for a different date, use the AvailabilityTable.availableFrom() method.
• Marked the Resource.setAvailableFrom() method as deprecated. The Available From attribute is derived from the resource's availability table. Changes to the Available From attribute should now be made by modifying the availability table.
• Updated the Resource attribute Available To to ensure that this is calculated from the resource's availability table. Note that the Resource.getAvailableTo() method will return the resource's Available To attribute for the current date. To retrieve the Available To attribute for a different date, use the AvailabilityTable.availableTo() method.
• Marked the Resource.setAvailableTo() method as deprecated. The Available To attribute is derived from the resource's availability table. Changes to the Available To attribute should now be made by modifying the availability table.

• When writing an enum value of a JSON file, ensure we write the original enum name rather than the value return by toString. This provides more meaningful output (Potentially breaking change if you use the Ruby gem or consume the JSON output directly. Affected attributes are project properties: currency symbol position, time format, date format, bar text date format, schedule from, mpx file version; resource attribute: type).
• Ensure invalid cost rate table data is handled gracefully when reading from MSPDI files.
