All releases of OrientDB
Release Notes: A new eval() function for executing expressions, new if() and ifnull() functions, support for server-side configuration for functions, new DELETE VERTEX and DELETE EDGE commands, execution of database functions from SQL commands, and a new create cluster command. Two graph algorithms were bundled: Dijkstra and ShortestPath between vertices. Opening time when a connection is reused from the pool was improved. Management of indexes in ORDER BY was improved. The schema has a new API for handling custom fields. HTTP/REST has support for fetch-plan and limit in "command".
Release Notes: New server-side functions were provided. These are like stored procedures for RDBMS but in JavaScript. New record level security was provided, and the profiler now generates snapshots of metrics. JMX is now a plugin and is no longer installed by default. An automatic rebuild of the schema index is performed on restart after a crash/hard shutdown. A new EXPLAIN SQL command allows you to profile any command, and a LET keyword can be used to set context variables. support for sub-queries in CREATE EDGE was provided. The Object Database JPA interface now supports a configurable naming policy. New abstract classes were provided. Automatic backup can now start at a concrete time. 65 bugs were fixed in total.
Release Notes: This release adds a new distributed server architecture with a balance of workload, full replication, and management of failures, a new MMAP manager optimized for 64bit OSes, new support for binary keys and collections in composite keys in Index, support for in-memory database replication, Object Database support for attaching/detaching, ENUM and binary data (ORecordBytes), a DROP CLUSTER command for SQL, INSERT which supports clusters, and new CREATE VERTEX and CREATE EDGE commands, support for the Gephi visual tool, and 50 bugfixes.
Release Notes: This release adds support for the TinkerPop 2.0 technology stack, adds a new OBinary type to index binary fields, and fixes some bugs.
Release Notes: A new Multi-Master Replication architecture. A new Object Database interface that uses run-time enhancement. Now handles lazy loading, and is lighter and faster than before. A new OTraverse class to traverse graphs via the Java API using a stack-free approach. Data segments: support for multiple ones and create/drop commands. New ODocument.undo() to revert local changes. New Server Side Scripting support. Query: new context variables. Console: a new check database command. Studio: improved Graph management. Improved OSGi support. Fixes for more than 40 bugs in total.
Release Notes: New studio look and feel and an improved Query panel. SQL: new subquery, a new SKIP keyword for pagination, and INSERT accepts SET syntax like SQL UPDATE. Updated Tinkerpop stack: Gremlin 1.5, Blueprints 1.2, and Pipes 1.0. Schema: new support for metadata on property. Many bugs have been fixed (35 issues in total).
Release Notes: This release adds a new TRAVERSE command to traverse records by relationships, a new fetch plan to support more complex use cases, an asynchronous API to speed inserts, updates, and deletes via a remote network, a new DECIMAL type to handle currency without the pains of float and double types, a strict schema mode to work like a Relational DBMS, resolution of the "big-node" problem when a record has many links to other records by using an MVRB-Tree to handle relationships, new NOT and INSTANCEOF operators for SQL, an index which works against MAP types, support for JPA @Embedded annotation, and bugfixes for 54 issues.
Release Notes: Transactions: improved speed, up to 500x. New Multi-Master replication (will be final in the next v1.0). The SQL insert supports MAP syntax. There is a new date() function. The HTTP interface has JSONP support. create-database, import-database, and export-database have been added, and many bugs have been fixed (34 issues in total).
Release Notes: Link navigation was improved in the SQL engine. The console received a new "list databases" command. The index now supports composite indexes and indexing of collections. JPA now supports @Embedded and @Transient annotations. In Object Database, lazy loading can now be enabled or disabled. Server has a new automatic backup task and can be installed as a Windows Service. Load balancing in clustered configuration was added to the client.
Release Notes: The new SQL [] operator was added to extract items from lists, sets, maps, and arrays. ORDER BY works with projection alias. Cross trees and graphs in projections. The IN operator uses Index when available. All known bugs on transaction recovery were fixed. The memory management of MVRB-Tree was rewritten to be faster and to use much less RAM. The common and core modules are compatible with Java 5.
