• Improve resource hierarchy handling.
• Improve handling of external tasks read from MSPDI files.
• Improve handling of resource assignments read from Asta PP files containing multiple baselines.
• Improve filtering to ignore hammock tasks in Asta PP files and ensure that non-hammock items are not incorrectly ignored.

• Ensure that invalid duplicate Unique ID values encountered when reading schedule data are renumbered to maintain uniqueness.
• Improve reading certain FastTrack FTS files.
• Roll up the expense item at completion values read from P6 schedules to the task Fixed Cost attribute.

Version 12.0.0

• NOTE: this is a major version release, breaking changes have been made to the MPXJ API as documented below.
• Timestamps, dates, and times are now represented by java.time.LocalDateTime, java.time.LocalDate and java.time.LocalTime respectively, rather than java.util.Date as they were originally.
• For .Net users, new ToDateTime and ToNullableDateTime extension methods have been provided to convert java.time.LocalDateTime, java.time.LocalDate, java.time.LocalTime to DateTime instances.
• For .Net users, new ToJavaLocalDateTime, ToJavaLocalDate and ToJavaLocalTime extension methods have been provided to convert DateTime instances to java.time.LocalDateTime, java.time.LocalDate, and java.time.LocalTime.

Version 11.5.4

• Improve accuracy of dates read from Synchro, Suretrak and Turboproject files.
• By default ignore errors in individual records read from XER files. This matches P6's behavior when importing XER files. Use the PrimaveraXERFileReader.setIgnoreErrors method to change the behavior.

• When writing an XER file, provide the necessary default values to allow non-P6 schedules to be successfully imported into P6.
• Ensure multi-day exceptions are written to XER files correctly.
• Ensure GanttProject exception dates are read correctly.
• More closely match the Planner predecessor lag calculation.
• Ensure that java.sql.Date values are correctly formatted when writing XER files.
• When reading from a P6 database, check to ensure the location table is present before attemting to read locations.

Version 11.5.2

• Improve accuracy of calendar data read from certain Powerproject schedules.
• Improve handling of unusual XER files with calendar time ranges expressed in 12-hour format.
• Correctly parse midnight represented as 24:00:00 from MSPDI files written by certain non-Microsoft Project applications.
• For MSPDI files produced by applications other than Microsoft Project which have an incorrectly nested calendar hierarchy, avoid pruning derived calendars which are referenced elsewhere in the hierarchy.
