2.12.1.0

• Added upsertWhere and upsertManyWhere to persistent-postgresql. #1222.

2.12.0.0

• Decomposed HaskellName into ConstraintNameHS, EntityNameHS, FieldNameHS. Decomposed DBName into ConstraintNameDB, EntityNameDB, FieldNameDB respectively. #1174

• Foreign Key improvements [#1121] https://github.com/yesodweb/persistent/pull/1121
  • It is now supported to refer to a table with an auto generated Primary Kay
  • It is now supported to refer to non-primary fields, using the keyword References
• Implement interval support. #1053
• #1060
  • The QuasiQuoter now supports OnDelete and OnUpdate cascade options.
• Handle foreign key constraint names over 63 characters. See #996 for details.
• Fix a bug in upsertSql query which had not been discovered previously because the query wasn’t actually used. #856
• #1072 Refactored test/JSONTest.hs to use hspec
  • added runConn_ to run a db connection and return result

• Remove unnecessary deriving of Typeable #1114
• Add support for configuring the number of stripes and idle timeout for connection pools #1098
  • PostgresConf has two new fields to configure these values.
    • Its FromJSON instance will default stripes to 1 and idle timeout to 600 seconds

  • Add createPostgresqlPoolWithConf and withPostgresqlPoolWithConf, which take a PostgresConf for the new configuration.
