+Upgrade JGit to 4.7.2.201807261330-r.
+
+  This version includes several fixes including a fix for issue 9153 which
+  prevented querying for filenames with special characters, and fixes
+  related to cleaning up ref directories after running GC.
+
+  It also includes the fix
+  [Honor trustFolderStats also when reading packed-refs](https://git.eclipse.org/r/#/c/112015/).
+  Users should note that for repositories with a high number of references
+  (for example in excess of 300K refs) and in a server with high traffic,
+  this solution may not scale well and should be tested carefully.
