[Frank Celler]

A maintenance release for ArangoDB 2.2 is available from the usual channels.

v2.2.6 (2014-10-20)
-------------------

* fixed issue #972: Compilation Issue

* fixed issue #743: temporary directories are now unique and one can read
  off the tool that created them, if empty, they are removed atexit

I just found that the following things also occur in the 2.2.6 CHANGELOG and are probably worth a notice:

* Highly improved performance of all AQL GRAPH_* functions.

* Orphan collections in general graphs can now be found via GRAPH_VERTICES
  if either "any" or no direction is defined

* Fixed documentation for AQL function GRAPH_NEIGHBORS.
  The option "vertexCollectionRestriction" is meant to filter the target
  vertices only, and should not filter the path.

* Fixed a bug in GRAPH_NEIGHBORS which enforced only empty results
  under certain conditions
