v2.7.0

New features and improvements

• You can now choose between two different storage modes:
  • Transactional mode - the default database mode that favors
    strongly-consistent ACID transactions using WAL files and periodic
    snapshots, but requires more time and resources during data import and
    analysis.
  • Analytical mode - speeds up import and data analysis but offers no ACID
    guarantees besides manually created snapshots.
    Switch between modes within the session using the STORAGE MODE IN_MEMORY_{TRANSACTIONAL|ANALYTICAL}; query. #772
• You can now call subqueries inside existing queries using the CALL clause. #794
• When you want to filter data using properties that all have label:property
  indexes set, you can make Memgraph analyze the properties on all or several
  labels with the ANALYZE GRAPH; query. By calculating the distribution of
  property values, Memgraph will be able to select the optimal index for the
  query and it will execute faster. #812
• If, for example, you are no longer interested in the results of the query you
  ran, or the procedure you built is running in an infinite loop, you can stop
  the transaction with the TERMINATE TRANSACTIONS tid; query; Find out the
  transaction ID with SHOW TRANSACTIONS; query. #790
• With the new flag password-encryption-algorithm you can choose between
  bcrypt, sha256, and sha256-multiple encryption algorithms. SHA256 offers
  better performance compared to the more secure but less performant bcrypt. #839
• Import using the LOAD CSV clause has been further improved by

Bugfixes

• The users who have global visibility on the graph will experience a slight
  improvement in performance regarding label-based access control as the engine
  no longer check privileges for each node. #837
• The All shortest paths algorithm now supports multiedges. #832
