MySQL NDB Cluster 7.5 Release Notes
        Building with CMake3 is now
        supported by the
        compile-cluster script included
        in the NDB source distribution.
       (WL #12303)
Important Change: 
        The dependency of ndb_restore on the
        NDBT library, which is used for internal
        testing only, has been removed. This means that the program no
        longer prints NDBT_ProgramExit: ... when
        terminating. Applications that depend upon this behavior should
        be updated to reflect this change when upgrading to this
        release.
       (WL #13117)
        The requestInfo fields for the long and short
        forms of the LQHKEYREQ signal had different
        definitions; bits used for the key length in the short version
        were reused for flags in the long version, since the key length
        is implicit in the section length of the long version of the
        signal but it was possible for long LQHKEYREQ
        signals to contain a keylength in these same bits, which could
        be misinterpreted by the receiving local query handler,
        potentially leading to errors. Checks have now been implemented
        to make sure that this no longer happens.
       (Bug #29820838)
        Long TCKEYREQ signals did not always use the
        expected format when invoked from TCINDXREQ
        processing.
       (Bug #29772731)
        Improved error message printed when the maximum offset for a
        FIXED column is exceeded.
       (Bug #29714670)
        Data nodes could fail due to an assert in the
        DBTC block under certain circumstances in
        resource-constrained environments.
       (Bug #29528188)
        When restoring TINYBLOB columns,
        ndb_restore now treats them as having the
        BINARY character set.
       (Bug #29486538)
Restoration of epochs by ndb_restore failed due to temporary redo errors. Now ndb_restore retries epoch updates when such errors occur. (Bug #29466089)
        ndb_restore
        --restore-epoch incorrectly
        reported the stop GCP as 1 less than the actual position.
       (Bug #29343655)
Added support which was missing in ndb_restore for conversions between the following sets of types:
