We have encountered possible bug in source control while merging branches and thought it might be a reported bug. Currently we have Team Foundation Server 2013 Update 3 and I try to find release notes about Update4, but without any results. Microsoft has posted a lot about Visual Studio updates, but none about TFS.
Please help to find TFS Update4 release notes - particulary bugfix section.
Short info of problem : have DEV branch, created new branch by changeset 5000 [of 7000 changesets in total]. When opening merging window to continue merging, older changesets with numbers like 2444 and 3567 appears to be unmerged.
