OrientDB Graph Edition v1.5

• New PLOCAL (Paginated Local) storage engine. In comparison with LOCAL it's more durable (no usage of MMAP) and supports better concurrency on parallel transactions. To migrate your database to PLOCAL follow this guide: migrate-from-local-storage-engine-to-plocal
• New Hash Index type with better performance on lookups. It does not support ranges
• New "transactional" SQL command to execute commands inside a transaction. This is useful for
  "create edge" SQL command to avoid the graph get corrupted
• Import now migrates RIDs allowing to import databases in a different one from the original
• "Breadth first" strategy added on traversing (Java and SQL APIs)
• Server can limit maximum live connections (to prevent DOS)
• Fetch plan support in SQL statements and in binary protocol for synchronous commands too
• Bug fixing
