May 3, 2016, update for Project 2010 (KB3115001)

Applies to: Microsoft Project 2010 Service Pack 2

This article describes update KB3115001 for Microsoft Project 2010, which was released on May 3, 2016. This update has a prerequisite.

Improvements and fixes

Fixes the following issues:
  • Consider the following scenario:
    • A team member submits a status update.
    • A status manager approves the update.
    • A project manager opens the project and verifies that the status update has been applied correctly to the project.
    • The project manager then saves the project.

    In this situation, depending on the state of the project manager's local active cache, the updated version of the project may be overwritten by an older version of the project in the project manager's active cache. Therefore, the status updates that have been applied are lost.

  • This update also fixes the following issues:
    • After you remove all progress from a task, a leading split is added incorrectly to the task.
    • When a task is observed from the Gantt view, you may see an unexplained split, for example, at the end, and when you try to remove the split, it grows larger, and the task finish is now later than before.
