@ -6,6 +6,8 @@ devel
* added C++ implementation for AQL function `SHA512()`
* Added C++ implementation for the AQL TRANSLATE function
* renamed arangoimp to arangoimport for consistency
Release packages will still install arangoimp as a symlink so user scripts
invoking arangoimp do not need to be changed
