I recently updated from version 6.7.0 to 6.8.0 of Aspose.Tasks, and the output for the attached MPP file has changed when saving to pdf using project.Save(outputFilePath, SaveFileFormat.PDF).
In 6.7, the generated PDF has 15 pages and includes project dates in June and July.
In 6.8, the generated PDF is only 9 pages, and the output is cutoff at the end of May.
