ArangoDB 2.6.5 现已下载，此版本是个 bug 修复版本：
- fixed busy wait loop in scheduler threads that sometimes consumed 100% CPU while waiting for events on connections closed unexpectedly by the client side
- handle attribute indexBuckets when restoring collections via arangorestore. Previously theindexBuckets attribute value from the dump was ignored, and the server default value forindexBuckets was used when restoring a collection.
- fixed “EscapeValue already set error” crash in V8 actions that might have occurred when cancelling V8-based operations.
