We are proud to announce the release of Version 2.4 of our multi-model database ArangoDB. It’s ready for download now and available for all major platforms.

This release is a major step forward. Use Foxx to create your favorite microservice with a few clicks, dockerize it and access it via a REST/Web API from everywhere. – Dr. Frank Celler (CTO)

You can now use EcmaScript 6 features like iterators, symbols, maps and sets by default and enable even more ES6 features with ArangoDB start options. The V8 engine upgrade in ArangoDB 2.4 also improves performance and speeds up V8 garbage collections.

The ArangoDB query language (AQL) gets more efficient group count calculation queries, an optional return value for AQL data-modification queries and improved index handling in filtering AQL queries.

Foxx 2.0: The new Foxx-Generator is a framework that enables developers to build Hypermedia APIs easily. Developers can create Web APIs based on a semantic description of entities and transitions using a statechart alike design approach. Additional to the recently added job queues and authentication services, Foxx got a new web-frontend to easily create new or install Foxx applications from Github or the ArangoDB Store.

Try the new tutorial Foxx in 10 Minutes to build your first Foxx application. Starting with a new Foxx app has never been easier.

Along with ArangoDB the new light-weight JavaScript driver arangojs 3.0 is ready to use.

A maintenance release for ArangoDB 2.3 is available for download or via your favourite package manager.

v2.3.3 (2014-12-17)
-------------------

* fixed error handling in instantiation of distributed AQL queries, this 
  also fixes a bug in cluster startup with many servers

* issue #1185: parse non-fractional JSON numbers with exponent (e.g. `4e-261`)

* issue #1159: allow --server.request-timeout and --server.connect-timeout of 0

v2.3.2 (2014-12-09)
-------------------

* fixed issue #1173: AQL Editor "Save current query" resets user password

* fixed missing makeDirectory when fetching a Foxx application from a zip file

* put in warning about default changed: fixed issue #1134: Change the default endpoint to localhost

* fixed issue #1163: invalid fullCount value returned from AQL

* fixed range operator precedence 

* limit default maximum number of plans created by AQL optimizer to 256 (from 1024)

* make AQL optimizer not generate an extra plan if an index can be used, but modify
  existing plans in place

* fixed AQL cursor ttl (time-to-live) issue

  Any user-specified cursor ttl value was not honored since 2.3.0.

* fixed segfault in AQL query hash index setup with unknown shapes

* fixed memleaks

* added AQL optimizer rule for removing `INTO` from a `COLLECT` statement if not needed

* fixed issue #1131

  This change provides the `KEEP` clause for `COLLECT ... INTO`. The `KEEP` clause
  allows controlling which variables will be kept in the variable created by `INTO`.

* fixed issue #1147, must protect dispatcher ID for etcd

A maintenance release for ArangoDB 2.3 is available from our download page and through the package manager.

• recreate password if missing during upgrade
• fixed issue #1126
• fixed non-working subquery index optimizations
• do not restrict summary of Foxx applications to 60 characters
• fixed display of “required” path parameters in Foxx application documentation
• added more optimizations of constants values in AQL FILTER conditions
• fixed invalid or-to-in optimization for FILTERs containing comparisons with boolean values
• fixed replication of _graphs collection
• added AQL list functions PUSH, POP, UNSHIFT, SHIFT, REMOVE_VALUES, REMOVE_VALUE, REMOVE_NTH and APPEND
• added AQL functions CALL and APPLY to dynamically call other functions
• fixed AQL optimizer cost estimation for LIMIT node
• prevent Foxx queues from permanently writing to the journal even when server is idle
• fixed AQL COLLECT statement with INTO clause, which copied more variables than v2.2 and thus lead to too much memory consumption. This deals with #1107.
• fixed AQL COLLECT statement, this concerned every COLLECT statement, only the first group had access to the values of the variables before the COLLECT statement. This deals with #1127.
• fixed some AQL internals, where sometimes too many items were fetched from upstream in the presence of a LIMIT clause. This should generally improve performance.

v2.2.7 (2014-11-19)

• fixed issue #1079: AQL editor: keyword WITH in UPDATE query is not highlighted
• fix memory leak in cluster nodes
• fixed registration of AQL user-defined functions in Web UI (JS shell)
• fixed error display in Web UI for certain errors (now error message is printed instead of ‘undefined’)
• fixed issue #1059: bug in js module console
• fixed issue #1056: “fs”: zip functions fail with passwords
• fixed issue #1063: Docs: measuring unit of –wal.logfile-size?
• fixed issue #1062: Docs: typo in 14.2 Example data

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
* 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

A maintenance release for ArangoDB 2.2 is available from the usual channels. v2.2.4 (2014-10-01) ——————-
* fixed accessing `_from` and `_to` attributes in `collection.byExample` and   `collection.firstExample`   These internal attributes were not handled properly in the mentioned functions, so   searching for them did not always produce documents
* fixed issue #1030: arangoimp 2.2.3 crashing, not logging on large Windows CSV file
* fixed issue #1025: Traversal not as expected in undirected graph
* fixed issue #1020   This requires re-introducing the startup option `–database.force-sync-properties`.   This option can again be used to force fsyncs of collection, index and database properties   stored as JSON strings on disk in files named `parameter.json`. Syncing these files after   a write may be necessary if the underlying storage does not sync file contents by itself   in a “sensible” amount of time after a file has been written and closed.   The default value is `true` so collection, index and database properties will always be   synced to disk immediately. This affects creating, renaming and dropping collections as   well as creating and dropping databases and indexes. Each of these operations will perform   an additional fsync on the `parameter.json` file if the option is set to `true`.   It might be sensible to set this option to `false` for workloads that create and drop a   lot of collections (e.g. test runs).   Document operations such as creating, updating and dropping documents are not affected   by this option.
* fixed issue #1016: AQL editor bug
* fixed issue #1014: WITHIN function returns wrong distance
* fixed AQL shortest path calculation in function `GRAPH_SHORTEST_PATH` to return   complete vertex objects instead of just vertex ids
* allow changing of attributes of documents stored in server-side JavaScript variables   Previously, the following did not work:

      var doc = db.collection.document(key);
      doc._key = "abc"; // overwriting internal attributes not supported
      doc.value = 123;  // overwriting existing attributes not supported 

Now, modifying documents stored in server-side variables (e.g. `doc` in the above case)   is supported. Modifying the variables will not update the documents in the database,   but will modify the JavaScript object (which can be written back to the database using   `db.collection.update` or `db.collection.replace`)

• fixed issue #997: arangoimp apparently doesn’t support files >2gig on Windows   large file support (requires using `_stat64` instead of `stat`) is now supported on   Windows
