#
# Activiti 5.15 shipped with some broken DDL statements for MySQL 5.6+ concering timestamps with millisecond precision
# If you are currently running on <= 5.14, simply execute the 5.15 and 5.15.1 update scripts.
# They have some duplication, but your shema will be in a correct state afterwards
# If you are currently running 5.15 on MySQL 5.6+ (by a sheer of luck of having data that didn't clash with the DDL),
# execute the 5.15.1 upgrade script, and all bugs shipped in Activiti 5.15 around these timestamp problems have been solved.
#

# Following statements are a duplication of the 5.15 updates. See above explanation why they need to be repeated. 

#  
# ACT-1867: MySQL DATETIME and TIMESTAMP precision
# The way this is done, is by creating a new column, pumping over all data
# and then removing the old column.
