v2.5.10

This release fixes:

  for the previous release
• index renaming for indexes that had particular assigned options, and
  that were being added rather than renamed or recreated under a different
  name
• date and datetimetz OracleDB type introspection: these two types
  were incorrectly recognized as datetime

• 2555: schema generation maps oracledb DATE fields to datetime
• 2611: #2508 Pass through index options when renaming index on table
• 2612: #2555 Fix date and datetimetz type mapping on Oracle
