• 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.

• Ensure that the user's selected progress period is used to set the project's status date attribute when reading Asta PP files.
• Ensure that a task's Complete Through attribute is not advanced to the start of the next working day (the behaviour of Microsoft Project prior to 2007 was to report Complete Through as the start of the next working day. This change ensures MPXJ matches versions of Microsoft Project from 2007 onwards. Previous behaviour can be restored using the ProjectConfig.setCompleteThroughIsNextWorkStart() method).

• 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.

• Write WBS and Activity notes to PMXML files.
• PMXML compatibility improvements to ensure files can be successfully imported into P6.

8.4.0 (2020-12-29)
