* When a baseline is added using one of the `ProjectFile.setBaseline` methods, ensure that the relevant baseline date is set in `ProjectProperties`.
* Marked the `JsonWriter` methods `setEncoding` and `getEncoding` as deprecated, use `setCharset` and `getCharset` instead.
* Marked the `PlannerWriter` methods `setEncoding` and `getEncoding` as deprecated, use `setCharset` and `getCharset` instead.
* Marked the `PrimaveraXERFileWriter` method `setEncoding` as deprecated, use `setCharset` instead.
* Marked the `ProjectCalendarHelper` method `getExpandedExceptionsWithWorkWeeks` as deprecated, use `ProjectCalendar.getExpandedCalendarExceptionsWithWorkWeeks` instead.
* 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.

* Improve handling of non-standard timestamp formats in XER files.

* Ensure calendars in Asta schedules have the correct name.
* Improve assignment of calendars to summary tasks when reading Asta schedules.
* Preserve calendar hierarchy when reading Asta schedules.

* Fix an issue where `UniversalProjectReader` would raise an exception when handling an unknown file type.
* Ensure that resource type is included as part of the resource assignment data when writing PMXML files.

* 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.
* The `CostAccount` method `getDescription()` has been marked as deprecated. Use the `getNotes()` or `getNotesObject()` method instead.
* The `CustomFieldValueItem` methods `getParent` and `setParent` have been marked as deprecated. Use the `getParentUniqueID` and `setParentUniqueID` methods instead.
* JSON output from MPXJ now includes more detail for custom field definitions read from MPP files.
* When reading a PMXML file, populate the Early/Late Start/Finish date attributes from the Remaining Early/Late Start/Finish date attributes.
* Fix an issue reading WBS ID for P3 and SureTrak schedules.

* Improve reading resource assignments from certain FastTrack FTS files.
