v2.2.2 (2014-08-08)

• allow storing non-reserved attribute names starting with an underscore Previous versions of ArangoDB parsed away all attribute names that started with an underscore (e.g. `_test`, `_foo`, `_bar`) on all levels of a document (root level and sub-attribute levels). While this behavior was documented, it was unintuitive and prevented storing documents inside other documents, e.g.:

{
        "_key" : "foo",
        "_type" : "mydoc",
        "references" : [
          {
            "_key" : "something",
            "_rev" : "...",
            "value" : 1
          },
          { 
            "_key" : "something else",
            "_rev" : "...",
            "value" : 2
          }
        ]
      }

In the above example, previous versions of ArangoDB removed all attributes and sub-attributes that started with underscores, meaning the embedded documents would lose some of their attributes. 2.2.2 should preserve such attributes, and will also allow storing user-defined attribute names on the top-level even if they start with underscores (such as `_type` in the above example).

• fix conversion of JavaScript String, Number and Boolean objects to JSON. Objects created in JavaScript using `new Number(…)`, `new String(…)`, or `new Boolean(…)` were not converted to JSON correctly.
• fixed a race condition on task registration (i.e. `require(“org/arangodb/tasks”).register()`) this race condition led to undefined behavior when a just-created task with no offset and no period was instantly executed and deleted by the task scheduler, before the `register` function returned to the caller.
• changed run-tests.sh to execute all suitable tests.
• switch to new version of gyp
• fixed upgrade button

A maintenance release for ArangoDB 2.2 is available. It will fix the performance problems encountered with the new graph module plus

v2.2.1 (2014-07-24)

• fixed issue with –check-version: when creating a new database the check failed
• issue #947 Foxx applicationContext missing some properties
• added startup option `–wal.suppress-shape-information` Setting this option to `true` will reduce memory and disk space usage and require less CPU time when modifying documents or edges. It should therefore be turned on for standalone ArangoDB servers. However, for servers that are used as replication masters, setting this option to `true` will effectively disable the usage of the write-ahead log for replication, so it should be set to `false` for any replication master servers. The default value for this option is `false`.
• added optional `ttl` attribute to specify result cursor expiration for HTTP API method `POST /_api/cursor` The `ttl` attribute can be used to prevent cursor results from timing out too early.
• (reported by Christian Neubauer): The problem was that in Google’s V8, signed and unsigned chars are not always declared cleanly. so we need to force v8 to compile with forced signed chars which is done by the Flag: -fsigned-char at least it is enough to follow the instructions of compiling arango on rasperry and add “CFLAGS=’-fsigned-char'” to the make command of V8 and remove the armv7=0
• Fixed a bug with the replication client. In the case of single document transactions the collection was not write locked.
