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.

• Currency amounts written to PMXML files are now rounded to 8 decimal places to more closely match the behavior of P6, and avoid unnecessary precision.
• Decimal amounts other than currency and duration are written to PMXML files with 15 decimal places to more closely match the behavior of P6.
• Fix an issue reading ConceptDraw calendars.
• Fixed a misspelled field name in the JSON output (Contributed by Daniel Taylor).

• Ensure the ProjectProperties name attribute is set correctly when reading XER files and P6 databases.
• The ProjectEntityContainer method renumberUniqueIDs has been marked as deprecated.

• 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.

Version 12.3.0

• 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.
• Ensure resource material labels written to MSPDI files meet Microsoft Project's naming requirements.
• Ensure the activity code value Name attribute is populated when read from an Asta PP file.
• Don't allow multiple values for an activity code when writing XER and PMXML files.
• The MSPDI and MPX writers now dynamically renumber Unique ID values which are too large for Microsoft Project. The original schedule is no longer modified to achieve this.

Version 12.2.0

• 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.
