Microsoft has provided pre-release information for Update Rollup 2 for CRM 2013 Service Pack 1 at https://support2.microsoft.com/kb/2963850/en-gb which is due for release in Q4 of 2014.
This update rollup can only be applied if you have installed Service Pack 1 for CRM 2013.
In the issues that are resolved section (you need to expand the section), a long list of fixes is detailed, but the following caught my attention being bugs that I've experienced or seen others report:
- When security roles are changed on a Microsoft Dynamics CRM 2013 form, the changes are not immediately being displayed.
- When using Server Side sync and setting the option to track all email within personal options, received emails do not change the Track button, this causes the View in CRM buttons to not get enabled within the command bar.
- When AutoSave is off in System Settings and a View is modified for an Entity in Customize this System an error is encountered: "Your changes have not been saved. To save you changes click cancel to stay on the page" This error occurs after changing the Edit Filter Criteria and selecting OK, then attempting to Add Columns.
The last item is one that has particularly bugged me - I'm looking forward to the fix.
