GA release v1.0.40

Notable:

• Fix to data integrity issue: corruption in timestamp(6) and datetime(6) microsecond values when smaller than 0.1sec, #452

• Fix to data integrity issue: support for alter table .. change column X where X is a different letter case than original column, #447
• supporting tables that reach up to and including max length (64 characters), #451

• http-throttle outputs clearer throttle messahes
• http-throttle is freno aware and outputs clearer throttle messahes

GA release v1.0.34

changes since 1.0.32: v1.0.32...v1.0.34

notable:

• Batched writes for applying binlog events onto ghost table: solving #348, this increases write capacity for gh-ost without introducing delays or stalls. See #352
• Only using internal heartbeat mechanism. --replication-lag-query is now deprecated and unused. gh-ost has its own subsecond resolution replication lag measurement which it uses both on the connected server as well as on the control-replicas. See #347
• support for --master-user and --master-password, for when master and replicas have different credentials.
• Add possibility to set server-id as command line flag - contribution by @cypiszzz, see #349
• --check-flag is a flag with which one can check if other flags are supported. Used for scripting and testing in lieu of evolving and changing versions. See #351

GA release v1.0.32

changes since 1.0.30: v1.0.30...v1.0.32
