This section contains change history information for MySQL Cluster
releases based on version 7.0 of the
NDB storage engine.
Previously, version 7.0 of
known as version 6.4, and early development versions of MySQL
Cluster NDB 7.0 were known as “MySQL Cluster 6.4”.
The first four releases in this series were identified using NDB
6.4.x version numbers (NDB 6.4.0 through NDB 6.4.3).
MySQL Cluster NDB 7.0.4 is the fifth release in this series. All future MySQL Cluster NDB 7.0 releases will use NDB 7.0.x version numbers.
Users running MySQL Cluster NDB 6.4.3 should upgrade to MySQL Cluster NDB 7.0.4 (or a later MySQL Cluster NDB 7.0 release).
For an overview of new features added in MySQL Cluster NDB 7.0, see MySQL Cluster Development in MySQL Cluster NDB 7.0.
When upgrading to a MySQL Cluster NDB 7.0 release from earlier MySQL Cluster releases, you should be aware of the following issues:
To perform an online upgrade to MySQL Cluster NDB 7.0 from a MySQL Cluster NDB 6.3 release, you must upgrade to MySQL Cluster NDB 7.0.6 or later. See Upgrade and downgrade compatibility: MySQL Cluster NDB 7.x, for more information.
You cannot use a mix of MySQL Cluster NDB 7.0 and earlier binaries, except as part of an online upgrade (where this is supported). You should replace all existing MySQL Cluster executables with the MySQL Cluster NDB 7.0 versions.
NDB API applications built against previous MySQL Cluster versions (NDB 6.3 and earlier) must be recompiled against against the MySQL Cluster NDB 7.0 sources.
